Hunting Wandering 3<z<8 Black Holes: Spatial Offsets in Ionization Ratio and Continuum Emission
Urvi Thakurdesai, Anthony J. Taylor, Steven L. Finkelstein +14
The early growth and assembly of supermassive black holes (SMBHs) remain key topics of interest in galaxy evolution. One of the scenarios predicted by theoretical models is that fr…
THRILS -- The High-(Redshift+Ionization) Line Search: Program Description & Redshift Catalog
Taylor A. Hutchison, Rebecca L. Larson, Pablo Arrabal Haro +46
To date, many spectroscopic confirmations of z>7 galaxies have been obtained using JWST/NIRSpec prism observations, with most of their physical properties inferred from these obser…
Significant Evidence of an AGN Contribution in GHZ2 at z = 12.34
Oscar A. Chavez Ortiz, Steven L. Finkelstein, Adele Plat +19
GHZ2 is among the highest-redshift galaxies discovered to date, exhibiting a spectrum rich with prominent emission lines in the rest-frame ultraviolet (UV) and optical. These featu…
The Prevalence of Bursty Star Formation in Low-Mass Galaxies at z=1-7 from Hα-to-UV Diagnostics
Marissa N. Perry, Anthony J. Taylor, Oscar A. Chavez Ortiz +15
We present an analysis of bursty star-formation histories (SFHs) of 346 star-forming galaxies at , selected from JWST/NIRSpec G395M and PRISM spectroscopy provided b…
Broad-Line AGN at 3.5<z<6: The Black Hole Mass Function and a Connection with Little Red Dots
Anthony J. Taylor, Steven L. Finkelstein, Dale D. Kocevski +48
We present a sample of 50 H-alpha detected broad-line active galactic nuclei (BLAGN) at redshifts 3.5<z<6.8 using data from the CEERS and RUBIES surveys. We select these sources di…
The Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX) Active Galactic Nuclei Catalog: the Fourth Data Release
Chenxu Liu, Karl Gebhardt, Erin Mentuch Cooper +7
We present the Active Galactic Nuclei (AGN) catalog from the fourth data release (HDR4) of the Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX). HETDEX is an untargete…
