Reconciling PTA and JWST and preparing for LISA with POMPOCO: a Parametrisation Of the Massive black hole POpulation for Comparison to Observations

A. Toubiana, L. Sberna, M. Volonteri +7

We develop a parametrised model to describe the formation and evolution of massive black holes, designed for comparisons with both electromagnetic and gravitational wave observatio…

UNCOVER: Significant Reddening in Cosmic Noon Quiescent Galaxies

Jared Siegel, David Setton, Jenny Greene +19

We explore the physical properties of five massive quiescent galaxies at , revealing the presence of non-negligible dust reservoirs. JWST NIRSpec observations were obtain…

The Small Sizes and High Implied Densities of `Little Red Dots' with Balmer Breaks Could Explain Their Broad Emission Lines Without an AGN

Josephine F. W. Baggen, Pieter van Dokkum, Gabriel Brammer +10

Early JWST studies found an apparent population of massive, compact galaxies at redshifts . Recently three of these galaxies were shown to have prominent Balmer breaks,…

Silencing the Giant: Evidence of AGN Feedback and Quenching in a Little Red Dot at z = 4.13

Vasily Kokorev, John Chisholm, Ryan Endsley +8

The James Webb Space Telescope (JWST) has uncovered a ubiquitous population of dust-obscured compact sources at . Many of these objects exhibit signs of active galactic…

Radio Scrutiny of the X-ray-Weak Tail of Low-Mass Active Galactic Nuclei: A Novel Signature of High-Eddington Accretion?

Jeremiah D. Paul, Richard M. Plotkin, W. N. Brandt +6

The supermassive black holes () that power luminous active galactic nuclei (AGNs), i.e., quasars, generally show a correlation between t…

[Ne v] emission from a faint epoch of reionization-era galaxy: evidence for a narrow-line intermediate mass black hole

J. Chisholm, D. A. Berg, R. Endsley +16

Here we present high spectral resolution NIRSpec observations of GN42437, a low-mass (log(M), compact (pc), extreme starburst galaxy…

Evidence for Intrinsic X-ray Weakness Among Red Quasars at Cosmic Noon

Yilun Ma, Andy Goulding, Jenny E. Greene +3

Quasar feedback is a key ingredient in shaping galaxy evolution. A rare population of extremely red quasars (ERQs) at are often associated with high-velocity [O III]$\lambd…
