We study the size and structure of globular cluster (GC) systems of 118 early-type galaxies from the NGVS, MATLAS, and ACSVCS surveys. Fitting Sérsic profiles, we investigate the relationship between effective radii of GC systems ( R _e _,gc ) and g

The formation of compact elliptical galaxies in the vicinity of a massive galaxy: the role of ram-pressure confinement

Autor: Thomas R. Quinn, Patrick Côté, Joseph Caruana, Chelsea Spengler, James Wadsley, Luis C. Ho, Samuel W. F. Earp, Min Du, Karl Fiteni, Victor P. Debattista, Peter Erwin, Mark A. Norris

Compact ellipticals (cEs) are outliers from the scaling relations of early-type galaxies, particularly the mass-metallicity relation which is an important outcome of feedback. The formation of such low-mass, but metal-rich and compact, objects is a l

The Pan-Andromeda Archaeological Survey is a survey of $>400$ square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive panorama of a $L_\star$ galaxy group to large projected galactocentric rad

We present an analysis of 39 nuclei and their early-type hosts in the Virgo Cluster using ten broadband filters: F300W, F475W, F850LP, F160W, $u^*griz$, and $K_s$. We describe the Virgo Redux program, which provides high-resolution UV and NIR imaging
