Early-type galaxies at intermediate redshift observed with HST WFC3: perspectives on recent star-formation
M. Rutkowski, H. Jeong, S. H. Cohen +7
We present an analysis of the stellar populations of 102 visually-selected early-type galaxies (ETGs) with spectroscopic redshifts (0.3<z<1.5) from observations in the Early Releas…
The role of major mergers in the size growth of intermediate-mass spheroids
S. Kaviraj, M. Huertas-Company, S. Cohen +11
We study of the role of major mergers (mass ratios >1:4) in driving size growth in high-redshift (1<z<2) spheroidal galaxies (SGs) with stellar masses between 10^9.5 MSun and 10^10…
Climate Change Task Force Report for the American Astronomical Society
T. A. Rector, L. Barbier, A. Couperis +11
The AAS Strategic Plan for 2021-26 called for the creation of a task force to identify how the AAS can meet the goals of the Paris Agreement. The AAS and its membership recognize t…
On the observability of individual Population III stars and their stellar-mass black hole accretion disks through cluster caustic transits
Rogier A. Windhorst, M. Alpaslan, S. Andrews +44
Recent near-IR power-spectra and panchromatic Extragalactic Background Light measurements provide upper limits on the near-IR surface brightness (SB>31 mag/arcsec^2) that may come…
The insignificance of major mergers in driving star formation at z~2
S. Kaviraj, S. Cohen, R. A. Windhorst +7
We study the significance of major-merger-driven star formation in the early Universe, by quantifying the contribution of this process to the total star formation budget in 80 mass…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
