Efficient survey design for finding high-redshift galaxies with JWST
Luka Vujeva, Charles L. Steinhardt, Christian Kragh Jespersen +9
Several large JWST blank field observing programs have not yet discovered the first galaxies expected to form at . This has motivated the search for more effecti…
UNCOVER: The growth of the first massive black holes from JWST/NIRSpec -- spectroscopic redshift confirmation of an X-ray luminous AGN at z=10.1
Andy D. Goulding, Jenny E. Greene, David J. Setton +27
The James Webb Space Telescope is now detecting early black holes (BHs) as they transition from "seeds" to supermassive BHs. Recently Bogdan et al. (2023) reported the detection of…
A persistent excess of galaxy-galaxy strong lensing observed in galaxy clusters
Massimo Meneghetti, Weiguang Cui, Elena Rasia +18
Previous studies have revealed that the estimated probability of galaxy-galaxy strong lensing in observed galaxy clusters exceeds the expectations from the Cold Dark Matter cos…
First Detection of an Over-Massive Black Hole Galaxy UHZ1: Evidence for Heavy Black Hole Seed Formation from Direct Collapse
Priyamvada Natarajan, Fabio Pacucci, Angelo Ricarte +3
The recent Chandra-JWST discovery of a quasar in the z = 10.1 galaxy UHZ1 reveals that accreting supermassive black holes (SMBHs) were already in place 470 million years after the…
The NANOGrav 15-year Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111
The NANOGrav 15-year data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gr…
Fly-by galaxy encounters with multiple black holes produce star-forming linear wakes
Nianyi Chen, Patrick LaChance, Yueying Ni +4
We look for simulated star-forming linear wakes such as the one recently discovered by van Dokkum et al. (2023) in the cosmological hydrodynamical simulation ASTRID. Amongst the ru…
