Pinpointing the cosmic web between massive galaxy clusters I. The incidence of HI and OVI as WHIM tracers

Karen Martínez-Acosta, Nicolas Tejos, Ismael Pessa +6

At redshift z<1, the CDM paradigm predicts that 40-50\% of baryons reside in the warm-hot intergalactic medium (WHIM) within cosmic web filaments. Characterizing the physi…

Cool CGM MgII Absorption Across the Star-Forming, Green Valley, and Quiescent Transition

Simon Xinlin Wu, Rongmon Bordoloi, Robert A. Simcoe +4

We investigate the distribution and kinematics of cool circumgalactic medium (CGM) gas across the star-forming to quiescent transition using MgII absorption for 716 galaxies spanni…

Observing Co-Located Neutral and Ionized Gas-Phase Iron Depletion in the Magellanic Clouds

Yun Qi Li, Jessica K. Werk, Caleb R. Choban +5

Depletion is the observed phenomenon where gas-phase elemental abundances are reduced through accretion onto dust grains. We measure neutral gas-phase elemental abundances (S, Fe)…

Ardua: Unveiling the Baryon Cycle from Stars to the Cosmic Web

Carlos J. Vargas, Caroline Kilbourne, Haeun Chung +29

The circumgalactic medium (CGM) -- the multiphase gas reservoirs surrounding galaxies -- remains the least understood component of the baryon cycle governing galaxy growth, despite…

A First Measurement of Circumgalactic Dust Reddening from Only 4.6 deg of the Rubin Observatory's Data Preview 1

John Franklin Crenshaw, Matthew McQuinn, Jessica K. Werk

We present the first measurement of circumgalactic dust reddening from the Vera C. Rubin Observatory, using only 4.6 deg of ComCam Data Preview 1 --- roughly of the fi…

Revealing Cosmic Ecosystems with the Hubble Space Telescope in 2030s and Beyond

Sanchayeeta Borthakur, Tanmay Singh, David French +22

Ultraviolet spectroscopy with the Hubble Space Telescope (HST) provides the most direct and sensitive probe of the disk-circumgalactic medium (CGM) interface at radii of 20 kpc, wh…
