When Spectral Modeling Meets Convolutional Networks: A Method for Discovering Reionization-era Lensed Quasars in Multi-band Imaging Data
Irham Taufik Andika, Knud Jahnke, Arjen van der Wel +8
Over the last two decades, around 300 quasars have been discovered at , yet only one has identified as being strongly gravitationally lensed. We explore a new approach -…
Detection of stellar light from quasar host galaxies at redshifts above 6
Xuheng Ding, Masafusa Onoue, John D. Silverman +41
The detection of starlight from the host galaxies of quasars during the reionization epoch () has been elusive, even with deep HST observations. The current highest redshift q…
Staring at the Shadows of Archaic Galaxies: Damped Ly and Metal Absorbers toward a Young Weak-line Quasar
Irham Taufik Andika, Knud Jahnke, Eduardo Bañados +6
We characterize the Ly halo and absorption systems toward PSO J083+11, a unique weak-line quasar, using Gemini/GNIRS, Magellan/FIRE, and VLT/MUSE data. Strong absorpt…
