Rubin LSST DP2 unveils almost-dark galaxies in the Virgo Cluster
Minh Ngoc Le, Johan H. Knapen, Željko Ivezić +27
Galaxies with the faintest surface brightness are currently known only in the Local Group. Similar objects should exist beyond our vicinity and are crucial for understanding galaxy…
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…
The haloes and environments of nearby galaxies (HERON) -- III. A 45 kpc spiral structure in the GLSB galaxy UGC 4599
Aleksandr V. Mosenkov, R. Michael Rich, Michael Fusco +10
We use a 0.7-m telescope in the framework of the Halos and Environments of Nearby Galaxies (HERON) survey to probe low surface brightness structures in nearby galaxies. One of our…
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,…
The AMIGA sample of isolated galaxies. XIV. Disc breaks and interactions through ultra-deep optical imaging
P. M. Sánchez-Alarcón, J. Román, J. H. Knapen +10
In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently isolated are thus interest…
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…
