Measurements of quasar proximity zones with the Ly forest of DESI Y1 quasars

Ryuichiro Hada, Paul Martini, David H. Weinberg +41

The intergalactic medium (IGM) around quasars is shaped by their dense environments and by their excess ionizing radiation, forming a "quasar proximity zone" whose size and anisotr…

The variability angular diameter distance and the intrinsic brightness temperature of active galactic nuclei

Whee Yeon Cheong, Sang-Sung Lee, Chanwoo Song +5

Context. It has recently been suggested that angular diameter distances derived from comparing the variability timescales of blazars to angular size measurements with very long bas…

Probing the nature of gravity in the low-acceleration limit: wide binaries of extreme separations with perspective effects

Youngsub Yoon, Yong Tian, Kyu-Hyun Chae

Recent statistical analyses of wide binaries have revealed a boost in gravitational acceleration with respect to the prediction by Newtonian gravity at low internal accelerations $…

Unveiling the nature and fate of the almost-dark cloud AGC 226178 through HI mapping

Yu-Zhu Sun, Hong-Xin Zhang, Elias Brinks +18

The origin of extragalactic, almost dark HI clouds with extreme gas-to-stellar mass ratios remains poorly understood. We investigate the nature and fate of the "almost dark" cloud…
