We present new empirical estimates of the ΔV bump HB parameter for 15 Galactic globular clusters (GGCs) using accurate and homogeneous ground-based optical data...
Outside-In Disk Evolution in the Large Magellanic Cloud
From the analysis of the color-magnitude diagrams and color functions of four wide LMC fields located from ~=2 to 6 kpc from the kinematic center of the LMC we...
Panning for gold, but finding helium: Discovery of the ultra-stripped supernova SN 2019wxt from gravitational-wave follow-up observations
We present the results from multi-wavelength observations of a transient discovered during an intensive follow-up campaign of S191213g, a gravitational wave (GW...
Photometric Properties of the M33 Star Cluster System

Proper Motions and Orbits of Distant Local Group Dwarf Galaxies from a Combination of Gaia and Hubble Data
We have determined the proper motions (PMs) of 12 dwarf galaxies in the Local Group (LG), ranging from the outer Milky Way (MW) halo to the edge of the LG. We...
Proper Motions of Local Group Dwarf Spheroidal Galaxies I: First Ground-Based Results for Fornax
In this article we present in detail the methodology and the first results of a ground-based program to determine the absolute proper motion of the Fornax dwarf...
