Galaxy mergers in Subaru HSC-SSP: a deep representation learning approach for identification and the role of environment on merger incidence
Kiyoaki Christopher Omori, Connor Bottrell, Mike Walmsley +7
We take a deep learning-based approach for galaxy merger identification in Subaru HSC-SSP, specifically through the use of deep representation learning and fine-tuning, with the ai…
A rest-frame near-IR study of clumps in galaxies at 1 < z < 2 using JWST/NIRCam: connection to galaxy bulges
Boris S. Kalita, John D. Silverman, Emanuele Daddi +4
A key question in galaxy evolution has been the importance of the apparent `clumpiness' of high redshift galaxies. Until now, this property has been primarily investigated in rest-…
COSMOS-Web: Intrinsically Luminous z10 Galaxy Candidates Test Early Stellar Mass Assembly
Caitlin M. Casey, Hollis B. Akins, Marko Shuntov +39
We report the discovery of 15 exceptionally luminous candidate galaxies discovered in the first 0.28 deg of JWST/NIRCam imaging from the COSMOS-Web Sur…
IllustrisTNG in the HSC-SSP: image data release and the major role of mini mergers as drivers of asymmetry and star formation
Connor Bottrell, Hassen M. Yesuf, Gergö Popping +13
At fixed galaxy stellar mass, there is a clear observational connection between structural asymmetry and offset from the star forming main sequence, SFMS. Herein, we use the TNG…
A Robust Bayesian Meta-Analysis for Estimating the Hubble Constant via Time Delay Cosmography
Hyungsuk Tak, Xuheng Ding
We propose a Bayesian meta-analysis to infer the current expansion rate of the Universe, called the Hubble constant (), via time delay cosmography. Inputs of the meta-analysis…
Uncovering a Massive z~7.7 Galaxy Hosting a Heavily Obscured Radio-Loud QSO Candidate in COSMOS-Web
Erini Lambrides, Marco Chiaberge, Arianna Long +47
In this letter, we report the discovery of the highest redshift, heavily obscured, radio-loud AGN candidate selected using JWST NIRCam/MIRI, mid-IR, sub-mm, and radio imaging in th…
Unveiling the distant Universe: Characterizing Galaxies in the first epoch of COSMOS-Web
Maximilien Franco, Hollis B. Akins, Caitlin M. Casey +47
We report the identification of 15 galaxy candidates at using the initial COSMOS-Web JWST observations over 77 arcmin through four NIRCam filters (F115W, F150W, F277W,…
Resolving galactic-scale obscuration of X-ray AGN at with COSMOS-Web
John D. Silverman, Vincenzo Mainieri, Xuheng Ding +25
A large fraction of the accreting supermassive black hole population is shrouded by copious amounts of gas and dust, particularly in the distant () Universe. While much…
Strong gravitational lensing by AGNs as a probe of the quasar-host relations in the distant Universe
Martin Millon, Frédéric Courbin, Aymeric Galan +4
The tight correlations found between masses of supermassive black holes (SMBHs) and the luminosities, total stellar masses, and velocity dispersions of their host galaxies are ofte…
Morphological asymmetries of quasar host galaxies with Subaru Hyper Suprime-Cam
Shenli Tang, John D. Silverman, Hassen M. Yesuf +7
How does the host galaxy morphology influence a central quasar or vice versa? We address this question by measuring the asymmetries of 2424 SDSS quasar hosts at using b…
Survey of Gravitationally Lensed Objects in HSC Imaging (SuGOHI). IX. Discovery of Strongly Lensed Quasar Candidates
James H. H. Chan, Kenneth C. Wong, Xuheng Ding +7
We report the discovery of new lensed quasar candidates in the imaging data of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) DR4, covering of the sk…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Host-galaxy Demographics of X-ray AGNs with Subaru Hyper Suprime-Cam
Junyao Li, John D. Silverman, Andrea Merloni +12
We investigate the physical properties, such as star-forming activity, disk vs. bulge nature, galaxy size, and obscuration of 3796 X-ray selected AGNs at in the eFEDS f…
Hidden Little Monsters: Spectroscopic Identification of Low-Mass, Broad-Line AGN at with CEERS
Dale D. Kocevski, Masafusa Onoue, Kohei Inayoshi +34
We report on the discovery of two low-luminosity, broad-line AGN at identified using JWST NIRSpec spectroscopy from the CEERS Survey. We detect broad H emission from both…
