The GOLIATH Survey: OVI Absorption Reveals CGM Evolution through the Starburst-to-Quiescent Transition in Massive Galaxies
Derick Flores, Rongmon Bordoloi, Jason Tumlinson +12
We present the GOLIATH survey (Galaxies, Outflows, and the Lifecycle of Immense, Active, Transforming Halos), a study of the multiphase circumgalactic medium (CGM) of massive ($\la…
Low Metallicity Gas on the Outskirts of the Local Group: the Circumgalactic Medium of Sextans B
Andrew J. Fox, Sapna Mishra, Frances H. Cashman +6
We present a UV absorption-line analysis of the circumgalactic medium (CGM) of Sextans B, a dwarf irregular galaxy at 1.3 Mpc distance on the outer frontier of the Local Group. Usi…
Discovery of Weak O VI Absorption in Underdense Regions of the Low-Redshift Intergalactic Medium
Sapna Mishra, Vikram Khaire, Romeo Pallikkara +2
We search for weak O VI absorption in the low-redshift intergalactic medium (IGM) using 82 high signal-to-noise quasar spectra obtained with the Cosmic Origins Spectrograph on boar…
New Interpretation for the Orientation of the LMC's Gaseous Arms B and E using ULLYSES
April Horton, Suraj Poudel, Kathleen A. Barger +20
The Large Magellanic Cloud (LMC) experiences disruption from tidal and ram-pressure forces as it travels through the halo of the Milky Way. In this project, we combine radio emissi…
The Warm-Hot Disk-Halo Interface Below the Perseus Spiral Arm
Ananya Goon Tuli, Nicolas Lehner, J. Christopher Howk +3
The Milky Way's disk-halo interface mediates energy and mass exchange between the interstellar thin disk and the halo. In the first detailed study of the Perseus arm's disk-halo in…
Studying the gaseous outskirts of galaxy groups with coherent Ly alpha absorption patterns
P. Richter, J. C. Charlton, A. J. Fox +2
In this study, we explore the properties of diffuse intergalactic gas residing in the outskirts of the four nearby, low-mass galaxy groups NGC1052, NGC5866, NGC4631, and NGC3992 (a…
