Mapping gas accretion and stellar kinematics to sub-kiloparsec scales in NGC 4696 with JWST/NIRSpec

Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35

We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (

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…

Photometric detection at of a galaxy beyond redshift with JWST/MIRI

Jakob M. Helton, George H. Rieke, Stacey Alberts +31

The James Webb Space Telescope (JWST) has spectroscopically confirmed numerous galaxies at . While weak rest-ultraviolet emission lines have only been seen in a handful of…

An Investigation Into The Selection and Colors of Little Red Dots and Active Galactic Nuclei

Kevin N. Hainline, Roberto Maiolino, Ignas Juodzbalis +25

Recently, a large number of compact sources at with blue UV slopes and extremely red rest-frame optical slopes have been found in James Webb Space Telescope (JWST) extragal…

No evidence for a significant evolution of - relation in massive galaxies up to z4

Yang Sun, Jianwei Lyu, George H. Rieke +19

Over the past two decades, tight correlations between black hole masses () and their host galaxy properties have been firmly established for massive galaxies ($\log(M_*/…

The Relation between AGN and Host Galaxy Properties in the JWST Era: I. Seyferts at Cosmic Noon are Obscured and Disturbed

Nina Bonaventura, Jianwei Lyu, George H. Rieke +22

The morphology of a galaxy reflects the mix of physical processes occurring within and around it, offering indirect clues to its formation and evolution. We apply both visual class…
