Uncertainty-Aware Deep Learning for the Ly Forest: CNN-Based Absorber Detection and Characterization
Paryag Sharma, Vikram Khaire, Ting-Yun Cheng +2
The Ly forest is a powerful probe of the intergalactic medium and small-scale matter distribution, but deriving absorber properties traditionally requires computationally expens…
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…
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 from the Cosmic Origins Spectrograph on the Hubble Sp…
Reconstructing galactic feedback history via the Lyman- forest with Habitable Worlds Observatory
Megan T. Tillman, Joseph N. Burchett, Blakesley Burkhart +2
Recent studies have focused on the low- Ly forest as a potential constraint on galactic feedback, as different AGN and stellar feedback models in hydrodynamic simulations pro…
Lyman Limit System with O VI in the Circumgalactic Environment of a Pair of Galaxies
Dheerajkumar Khonde, Purvi Udhwani, Anand Narayanan +3
We report on the analysis of a multiphase Lyman limit system (LLS) at identified towards the background quasar FBQS J0209-0438. The O VI doublet lines associated with t…
Searching for the Imprints of AGN Feedback on the Lyman Alpha Forest Around Luminous Red Galaxies
Vikram Khaire, Teng Hu, Joseph F. Hennawi +3
We explore the potential of using the low-redshift Lyman- (Ly) forest surrounding luminous red galaxies (LRGs) as a tool to constrain active galactic nuclei (AGN) feedback mo…
