A stellar dynamical mass measurement of an inactive black hole at redshift 2
Andrew B. Newman, Meng Gu, Sirio Belli +34
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…
JWST's PEARLS: A clumpy ring galaxy at
David Vizgan, Ming-Yang Zhuang, Ian Smail +22
Ring galaxies are an uncommon class of galaxies whose morphology is closely related to dynamical processes that govern galaxy evolution. Some ring galaxies, known as "collisional r…
A Compact Radio Ring with a Diffuse Envelope in LOFAR: Odd Radio Circle or Distinct Phenomenon?
M. Polletta, A. L. Coil, B. L. Frye +1
We report the discovery and investigate the nature of J1248+4826, an ORC-like source identified in the LOFAR Survey. We analyze its radio morphology, size, luminosity, and spectral…
Euclid Quick Data Release (Q1). The first Euclid view of Planck galaxy protocluster candidates at cosmic noon
Euclid Collaboration, T. Dusserre, H. Dole +339
[ABRIGED ABSTRACT] A large catalogue of candidate galaxy protoclusters with high star-formation rates was produced by the Planck collaboration. We search, in the first data release…
Lonely Little Red Dots: Challenges to the AGN-nature of little red dots through their clustering and spectral energy distributions
MarÃa Carranza-Escudero, Christopher J. Conselice, Nathan Adams +31
Observations with the James Webb Space Telescope (JWST) reveal a previously unseen population of compact red objects, known as ``little red dots`` (LRDs). We study a new photometri…
PASSAGES: The Discovery of a Strongly Lensed Protocluster Core Candidate at Cosmic Noon
Nicholas Foo, Kevin C. Harrington, Brenda Frye +24
Investigating the processes by which galaxies rapidly build up their stellar mass during the peak of their star formation () is crucial to advancing our understanding of the…
