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…

Spatial decomposition of Little Red Dots with JWST/NIRSpec IFU into broad-line red cores and narrow-line blue host galaxies

Yuzo Ishikawa, Anna-Christina Eilers, Rohan P. Naidu +11

Little Red Dots (LRDs) are a population of compact red sources discovered by the James Webb Space Telescope (JWST). Imaging and spectroscopy have shown that LRDs exhibit a complex…

Little Red Dots at z~2 in EIGER reveal a gentle decline with respect to their peak number density at z~5

Shrriya Kapoor, Jorryt Matthee, Alberto Torralba +10

We report the discovery of a sample of little red dots (LRDs) at identified from deep JWST/NIRCam imaging and wide-field slitless spectroscopy over arcmin f…

Possible chemical signatures of first-star enrichment in a very metal-poor galaxy overdensity near the end of reionization

Zihao Li, Koki Kakiichi, Lise Christensen +24

The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…

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…

The Synthetic Absorption Line Spectral Almanac (SALSA)

Dylan Nelson, Celine Peroux, Philipp Richter +10

We create the first large-scale mock spectroscopic survey of gas absorption sightlines traversing the interstellar medium (ISM), circumgalactic medium (CGM), and intergalactic medi…
