Fundamental Noise Limits of Infrared Detectors in the Presence of Readout Glow
Michael Bottom, Gustav Pettersson, Pavaman Bilgi +5
Read noise in infrared sensor arrays remains a major obstacle for ground- and space-based astronomy. It has long been recognized that the upcoming extremely large telescopes cannot…
SuperFIRE: Concept evolution of a seeing-limited broadband spectrograph for the GMT
Gustav M. Pettersson, Gábor Fűrész, Nathan P. Lourie +4
We are developing the SuperFIRE concept, which builds on the heritage of the FIRE spectrograph at Magellan, as a broadband (about 340 nm to 2.5 um) intermediate resolution (R=10,00…
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…
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…
Little Red Dots as Intermediate Mass, Super-Eddington Engines: Insights from Type IIn Supernovae and The 1837-1856 Great Eruption of Carinae
Rohan P. Naidu, Jorryt Matthee, Anna de Graaff +20
JWST's Little Red Dots (LRDs) display a unique constellation of features that do not occur simultaneously in any other class of galaxies or AGN. Here we observe that many of these…
Little Red Dot Host Galaxy Black Hole Star: A Gas-Enshrouded Heart at the Center of Every Little Red Dot
Wendy Q. Sun, Rohan P. Naidu, Jorryt Matthee +30
The central engines of Little Red Dots (LRDs) may be ``black hole stars" (BH*s), early stages of black hole growth characterized by dense gas envelopes. So far, the most direct evi…
