    Assembly bias describes the finding that the clustering of dark matter haloes depends on halo formation time at fixed halo mass. In this paper, we analyse the influence of assembly bias on galaxy clustering using both semi-analytical models (SAMs) and observational data. At fixed stellar mass, SAMs predict that the clustering of {\it central} galaxies depends on the specific star formation rate (sSFR), with more passive galaxies having a higher clustering amplitude. We find similar trends using SDSS group catalogues, and verify that these are not affected by possible biases due to the group finding algorithm. Low mass central galaxies reside in narrow bins of halo mass, so the observed trends of higher clustering amplitude for galaxies with lower sSFR is not driven by variations of the parent halo mass. We argue that the clustering dependence on sSFR represent a direct detection of assembly bias. In addition, contrary to what expected based on clustering of dark matter haloes, we find that low-mass central galaxies in SAMs with larger host halo mass have a {\it lower} clustering amplitude than their counter-parts residing in lower mass haloes. This results from the fact that, at fixed stellar mass, assembly bias has a stronger influence on clustering than the dependence on the parent halo mass.

    A tailward moving plasmoid (flux rope) was observed by the GEOTAIL spacecraft at [-22, 5, -3 RE GSE] after a period with strong geomagnetic activity on November 27, 1995. The structure exhibited classic plasmoid like signatures; bipolar Bz, a strong core field and tailward streaming ions. Measurements from the solar wind and the ground show that the GEOTAIL-observations were correlated with a change in the IMF and a substorm onset. Together, these observations suggest that the flux rope was launched as a result of magnetic reconnection during substorm onset, and that the reconnection site was located earthward of -22 RE. To our knowledge, observations of similar substorm associated flux rope formation and tailward streaming ions at such distances have not been reported earlier.

    Our daily life is surrounded by textual information. Nowadays, the automatic collection of textual information becomes possible owing to the drastic improvement of scene text detectors and recognizer. The purpose of this paper is to conduct a large-scale survey of co-occurrence between visual objects (such as book and car) and scene texts with a large image dataset and a state-of-the-art scene text detector and recognizer. Especially, we focus on the function of "label" texts, which are attached to objects for detailing the objects. By analyzing co-occurrence between objects and scene texts, it is possible to observe the statistics about the label texts and understand how the scene texts will be useful for recognizing the objects and vice versa.

    Authors: R. Stabell; P.S. Wesson;

    Galaxies emit radiation that forms a background of intergalactic light. The energy density at the present epoch of this radiation field depends mainly on three things: (1) the epoch at which galaxies formed; (2) the luminosity evolution that galaxies have undergone since they formed; (3) the cosmology (and in particular the present value H/sub 0/ of Hubble's parameter). We have calculated the expected energy density of the extragalactic background light (EBL) for (1) a range of galaxy formation epochs; (2) a range of luminosity-evolution parameters for galaxies (taking into account differing types of evolution for ellipticals and spirals); (3) a range of Robertson-Walker universe models (with and without the cosmological constant). We discuss how experiments presently being made to measure the EBL can be used to gain information on (1)--(3). Presently available upper limits on the EBL indicate that galaxies in general were not very much more luminous when young than they are now, or that H/sub 0/ lies nearer H/sub 0/=100 km sec/sup -1/ Mpc/sup -1/ than H/sub 0/=50 km sec/sup -1/ Mpc/sup -1/, or possibly both.

    We present Verifi2, a visual analytic system to support the investigation of misinformation on social media. On the one hand, social media platforms empower individuals and organizations by democratizing the sharing of information. On the other hand, even well-informed and experienced social media users are vulnerable to misinformation. To address the issue, various models and studies have emerged from multiple disciplines to detect and understand the effects of misinformation. However, there is still a lack of intuitive and accessible tools that help social media users distinguish misinformation from verified news. In this paper, we present Verifi2, a visual analytic system that uses state-of-the-art computational methods to highlight salient features from text, social network, and images. By exploring news on a source level through multiple coordinated views in Verifi2, users can interact with the complex dimensions that characterize misinformation and contrast how real and suspicious news outlets differ on these dimensions. To evaluate Verifi2, we conduct interviews with experts in digital media, journalism, education, psychology, and computing who study misinformation. Our interviews show promising potential for Verifi2 to serve as an educational tool on misinformation. Furthermore, our interview results highlight the complexity of the problem of combating misinformation and call for more work from the visualization community. Comment: 11 pages, 7 figures

    TMs paper presents first results of the Coronal Diagnostic Spectrometer (CDS) recently launched aboard the Sol, and Heliospheric observatory (SOHO). CDS is a twin spectrometer, operating in the extreme ultraviolet range 151-785 A. Thus, it can detect emission lines from trace elements in the corona and transition region which will be used to provide diagnostic information on the solar atmosphere. In this paper, we present early spectra and images, to illustrate the performance of the instrument and to pave the way for future studies.

    We statistically validated a sample of hot Neptune candidates applying a two-step vetting technique using DAVE and TRICERATOPS. We performed a systematic validation of 250 transit-like events in the Transiting Exoplanet Survey Satellite (TESS) archive in the parameter region defined by $P\leq 4$ d and $3R_\oplus\leq R\leq 5R_\oplus$. Through our analysis, we identified 18 hot Neptune-sized candidates, with a false positive probability $<50\%$. Nine of these planet candidates still need to be confirmed. For each of the nine targets we retrieved the stellar parameters using ARIADNE and derived constraints on the planetary parameters by fitting the lightcurves with the juliet package. Within this sample of nine candidates, we statistically validated (i.e, with false positive probability < $0.3\%$) two systems (TOI-277 b and TOI-1288 b) by re-processing the candidates with TRICERATOPS along with follow-up observations. These new validated exoplanets expand the known hot Neptunes population and are high-priority targets for future radial velocities follow-up. 24 pages, 20 figures. Accepted for publication on MNRAS

    Authors: Geoffrey W. Marcy;

    In 1995, periodic variations in the Doppler shift of the light from the star 51 Pegasi hinted at the presence of a planet -- the first ever detected around another Sun-like star. Then last year, spectral line variations appeared to be present, which could only be caused by an undulating, pulsating stellar surface, not an orbiting planet. But now the spectral evidence of pulsations has disappeared, leaving planets as the only plausible interpretation.

    A detailed analysis of the VLF data collected during January to December, 2003 at the low latitude station Jammu (geomag. lat., 22° 26′ N; L = 1.17) has yielded some unusual VLF events like whistler triplets of very high dispersion D ∼ 70 − 90 sec1/2. From the dispersion analysis of the whistler triplets, it is found that the individual whistlers of the triplets are one-hop high dispersion ducted whistlers having propagation path along higher and closely spaced L-values (L∼4.0) than the L-value of the recording station. The dispersion and occurrence characteristics of these high dispersion whistlers of the triplets are compared with those of the majority of low dispersion whistlers (D ∼ 30 − 40 sec1/2) recorded during the same period. Generation and propagation mechanisms are briefly discussed.

    We have conducted 3.6 cm radio continuum observations of the nearby starburst galaxy NGC 253 with the Effelsberg 100‐m telescope. The polarized emission reveals a prominent radio halo with the magnetic field mainly aligned parallel to the galactic disk. In the south‐east of NGC 253 a huge spur dominates, where the magnetic field lines are along the spur. As this spur can be interpreted as a starburst‐driven outflow, magnetic fields trace (or even control) the occurrence of collimated galactic outflows (chimneys). Thus NGC 253 serves as an ideal case to study the connection between galactic winds and the large‐scale magnetic field structure. With recently obtained VLA‐D observations at 6 cm, to be combined with the Effelsberg data, we will be able to examine this connection in more detail.

    Assembly bias describes the finding that the clustering of dark matter haloes depends on halo formation time at fixed halo mass. In this paper, we analyse the influence of assembly bias on galaxy clustering using both semi-analytical models (SAMs) and observational data. At fixed stellar mass, SAMs predict that the clustering of {\it central} galaxies depends on the specific star formation rate (sSFR), with more passive galaxies having a higher clustering amplitude. We find similar trends using SDSS group catalogues, and verify that these are not affected by possible biases due to the group finding algorithm. Low mass central galaxies reside in narrow bins of halo mass, so the observed trends of higher clustering amplitude for galaxies with lower sSFR is not driven by variations of the parent halo mass. We argue that the clustering dependence on sSFR represent a direct detection of assembly bias. In addition, contrary to what expected based on clustering of dark matter haloes, we find that low-mass central galaxies in SAMs with larger host halo mass have a {\it lower} clustering amplitude than their counter-parts residing in lower mass haloes. This results from the fact that, at fixed stellar mass, assembly bias has a stronger influence on clustering than the dependence on the parent halo mass.

    A tailward moving plasmoid (flux rope) was observed by the GEOTAIL spacecraft at [-22, 5, -3 RE GSE] after a period with strong geomagnetic activity on November 27, 1995. The structure exhibited classic plasmoid like signatures; bipolar Bz, a strong core field and tailward streaming ions. Measurements from the solar wind and the ground show that the GEOTAIL-observations were correlated with a change in the IMF and a substorm onset. Together, these observations suggest that the flux rope was launched as a result of magnetic reconnection during substorm onset, and that the reconnection site was located earthward of -22 RE. To our knowledge, observations of similar substorm associated flux rope formation and tailward streaming ions at such distances have not been reported earlier.

    Our daily life is surrounded by textual information. Nowadays, the automatic collection of textual information becomes possible owing to the drastic improvement of scene text detectors and recognizer. The purpose of this paper is to conduct a large-scale survey of co-occurrence between visual objects (such as book and car) and scene texts with a large image dataset and a state-of-the-art scene text detector and recognizer. Especially, we focus on the function of "label" texts, which are attached to objects for detailing the objects. By analyzing co-occurrence between objects and scene texts, it is possible to observe the statistics about the label texts and understand how the scene texts will be useful for recognizing the objects and vice versa.

    Galaxies emit radiation that forms a background of intergalactic light. The energy density at the present epoch of this radiation field depends mainly on three things: (1) the epoch at which galaxies formed; (2) the luminosity evolution that galaxies have undergone since they formed; (3) the cosmology (and in particular the present value H/sub 0/ of Hubble's parameter). We have calculated the expected energy density of the extragalactic background light (EBL) for (1) a range of galaxy formation epochs; (2) a range of luminosity-evolution parameters for galaxies (taking into account differing types of evolution for ellipticals and spirals); (3) a range of Robertson-Walker universe models (with and without the cosmological constant). We discuss how experiments presently being made to measure the EBL can be used to gain information on (1)--(3). Presently available upper limits on the EBL indicate that galaxies in general were not very much more luminous when young than they are now, or that H/sub 0/ lies nearer H/sub 0/=100 km sec/sup -1/ Mpc/sup -1/ than H/sub 0/=50 km sec/sup -1/ Mpc/sup -1/, or possibly both.
