The Disks In Scorpius-Centaurus Survey (DISCS) I: Four Newly-Resolved Debris Disks in Polarized Intensity Light

Posted by dbos Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Justin Hom, Thomas M. Esposito, Katie A. Crotts, Gaspard Duchêne, Jennifer Patience | Summary: The presence of infrared excesses around stars directly correlates to spatially-resolved imaging detections of circumstellar disks at both mm and optical/near-infrared wavelengths. High contrast imagers have resolved dozens of circumstellar disks with scattered […]

Redshift Assessment Infrastructure Layers (RAIL): Rubin-era photometric redshift stress-testing and at-scale production

Posted by dbos Stanford

Kavli Affiliate: Eric Charles | First 5 Authors: The RAIL Team, Jan Luca van den Busch, Eric Charles, Johann Cohen-Tanugi, Alice Crafford | Summary: Virtually all extragalactic use cases of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) require the use of galaxy redshift information, yet the vast majority of its […]

Evidence of a fraction of LIGO/Virgo/KAGRA events coming from active galactic nuclei

Posted by dbos Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Liang-Gui Zhu, Xian Chen, , , | Summary: The formation channels of the gravitational-wave (GW) sources detected by LIGO/Virgo/KAGRA (LVK) remain poorly constrained. Active galactic nucleus (AGN) has been proposed as one of the potential hosts but the fraction of GW events originating from AGNs has not […]

Measurement of the time-integrated $CP$ asymmetry in $D^0toπ^0π^0$ decays at Belle II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, Y. Ahn, N. Akopov, S. Alghamdi | Summary: We measure the time-integrated $CP$ asymmetry, $A_{CP}$, in $D^0topi^0pi^0$ decays reconstructed in $e^+e^-to cbar{c}$ events collected by Belle II during 2019–2022. The data corresponds to an integrated luminosity of 428$mathrm{fb}^{-1}$. The $D^0$ decays are […]

Abundant Population of Broad H$α$ Emitters in the GOODS-N Field Revealed by CONGRESS, FRESCO, and JADES

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Junyu Zhang, Eiichi Egami, Fengwu Sun, Xiaojing Lin, Jianwei Lyu | Summary: We present a spectroscopic search for broad H$alpha$ emitters at z~3.7-6.5 in the GOODS-N field, utilizing JWST/NIRCam slitless spectroscopy from FRESCO and CONGRESS, complemented by JADES imaging. We identify 19 broad H$alpha$ emitters with FWHM […]

Baryon Acoustic Oscillations from a Different Angle

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: This paper presents an alternative way of analysing Baryon Acoustic Oscillation (BAO) distance measurements via rotations to define new quantities Dperp and Dpar. These quantities allow simple tests of consistency with the Planck LCDM cosmology. The parameter Dperp is determined […]
