Dark Energy Survey: Modeling strategy for multiprobe cluster cosmology and validation for the Full Six-year Dataset

Posted by dbos Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Chun-Hao To, Elisabeth Krause, Chihway Chang, Hao-Yi Wu, Risa H. Wechsler | Summary: We introduce an updated To&Krause2021 model for joint analyses of cluster abundances and large-scale two-point correlations of weak lensing and galaxy and cluster clustering (termed CL+3x2pt analysis) and validate that this model meets […]

The Science of the Einstein Telescope

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Adrian Abac, Raul Abramo, Simone Albanesi, Angelica Albertini, Alessandro Agapito | Summary: Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science objectives, providing state-of-the-art predictions for the capabilities of ET in […]

The Chicago Carnegie Hubble Program: Improving the Calibration of SNe Ia with JWST Measurements of the Tip of the Red Giant Branch

Posted by dbos Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Taylor J. Hoyt, In Sung Jang, Wendy L. Freedman, Barry F. Madore, Kayla A. Owens | Summary: We present distances to ten supernova (SN) host galaxies determined via the red giant branch tip (TRGB) using JWST/NIRCAM and the F115W, F356W, and F444W bandpasses. Our analysis, including […]

BlackTHUNDER strikes twice: rest-frame Balmer-line absorption and high Eddington accretion rate in a Little Red Dot at $z=7.04$

Posted by dbos Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Francesco D’Eugenio, Roberto Maiolino, Michele Perna, Hannah Uebler, Xihan Ji | Summary: JWST spectroscopy has revealed a population of compact objects at redshifts $z=2$-9 with `v’-shaped spectral energy distributions, broad permitted lines, and, often, hydrogen Balmer absorption. Among these `Little Red Dots’ (LRDs), Abell2744-QSO1 at $z=7.04$ has […]
