The Cosmic Ultraviolet Baryon Survey X: Density and Pressure Profiles of Clumpy Circumgalactic Gas at

Suyash Kumar, Hsiao-Wen Chen, Gwen C. Rudie +14

The thermodynamic state and turbulent properties of the cool circumgalactic medium (CGM) are investigated for 23 galaxies and galaxy groups at intermediate redshift (--0.7)…

From IFS Maps to 3D Structure I: Constraining Geometry in the Circumgalactic Medium

Mandy C. Chen, Michael Rauch, Zhijie Qu +3

The three-dimensional geometric structure of the cool (T~ K) circumgalactic medium (CGM) -- the line-of-sight depth and the number of discrete clumps -- is poorly constrained…

The Low-Mass Baryon Cycle in QUEST Dwarf Galaxies I: Sample definition and first results

Ava Polzin, Hsiao-Wen Chen, Zhijie Qu +3

We introduce the QUEST Dwarfs program, which connects low-mass galaxies' stellar populations, interstellar medium, and circumgalactic medium in a large and coherently analyzed samp…

An emerging baryon cycle in a galaxy 500 million years after the Big Bang

Shengzhe Wang, Xin Wang, Hang Zhou +17

The emergence of stellar feedback as a regulator of galaxy growth marks a fundamental transition in cosmic history. At early times, rapid gas accretion and collapse may induce inte…

High-S/N Quasar Observations with HST/COS: Deep Fields for Spectroscopy

Andrew J. Fox, Jerry Kriss, Philipp Richter +49

Hubble is still in prime observing condition for making transformative discoveries in UV astronomy. In this white paper we describe the science case for a deep (S/N>30) UV spectros…

A Comprehensive Study of Morphology and Kinematics in Extended Nebulae Around UV Luminous Quasars at

Zhuoqi Liu, Sean D. Johnson, Eric F. Bell +20

Gas flows between galaxies and the circumgalactic medium (CGM) play a central role in galaxy evolution and can become observable as giant nebulae when illuminated by the quasars. W…

Probing Large-scale Structure and the Multi-Phase IGM at the Cosmic Noon -- Insights from a Joint Survey with Euclid, CSST, JPCam, and JUST

Jiang-Tao Li, Renato A. Dupke, Yan Gong +4

We present scientific and technical justifications of a potential coordinated Euclid/CSST/JPCam/JUST survey of the Euclid Deep Field North (EDF-N), aimed at probing the multi-phase…
