The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies

Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29

We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…

The new era of Lyman alpha emitters (LAEs): Efficiency in the selection criteria

P. Layana-Astudillo, I. Laferte-Urrutia, L. Guaita +6

The ODIN survey has detected thousands of Lyman-alpha emitting galaxies across seven sky fields, covering nearly one hundred square degrees. One of these regions is the SHELA field…

A Changing-Look Seyfert Discovered by eROSITA Reveals a Two-Component Broad-Line Region

Alex Markowitz, Mirko Krumpe, David Homan +12

Extreme sudden changes in the flow of accreting gas onto SMBHs manifest themselves via large-amplitude continuum variability and changes to broad Balmer emission profiles, driving…

A search for the first galaxies across deg of JWST imaging: new evidence for a rapid decline in star-formation activity at

D. J. McLeod, J. S. Dunlop, R. J. McLure +20

We present a new determination of the evolving galaxy UV luminosity function (LF) over the extreme redshift range , based on a wide-area search of 0.6 deg of JW…

Constraining the mass of the M31 ionized baryon Halo using CHIME/FRB Catalog 2

Lordrick A. Kahinga, J. Xavier Prochaska, Sunil Simha +21

The circumgalactic medium (CGM) surrounding galaxies is believed to be a significant reservoir of baryons, yet its total mass remains poorly constrained. We present a novel approac…

Searching for strong lensing by late-type galaxies in UNIONS

J. A. Acevedo Barroso, B. Clément, F. Courbin +8

Recent wide-field galaxy surveys have led to an explosion in the number of galaxy-scale strong gravitational lens candidates. However, the vast majority of them feature massive lum…
