Milky Way Satellite Census. I. The Observational Selection Function for Milky Way Satellites in DES Y3 and Pan-STARRS DR1
A. Drlica-Wagner, K. Bechtol, S. Mau +55
We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and PS1…
Two Ultra-Faint Milky Way Stellar Systems Discovered in Early Data from the DECam Local Volume Exploration Survey
S. Mau, W. Cerny, A. B. Pace +56
We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system, Centaurus I (DELVE J1238-40…
On the nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
David Martinez-Delgado, A. Katherina Vivas, Eva K. Grebel +35
Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their outer regions, which ultimatel…
Modelling the Milky Way. I -- Method and first results fitting the thick disk and halo with DES-Y3 data
A. Pieres, L. Girardi, E. Balbinot +53
We present MWFitting, a method to fit the stellar components of the Galaxy by comparing Hess Diagrams (HDs) from TRILEGAL models to real data. We apply MWFitting to photometric dat…
Brown dwarf census with the Dark Energy Survey year 3 data and the thin disk scale height of early L types
A. Carnero Rosell, B. Santiago, M. dal Ponte +44
In this paper we present a catalogue of 11,745 brown dwarfs with spectral types ranging from L0 to T9, photometrically classified using data from the Dark Energy Survey (DES) year…
Rediscovery of the Sixth Star Cluster in the Fornax Dwarf Spheroidal Galaxy
Mei-Yu Wang, Sergey Koposov, Alex Drlica-Wagner +58
Since first noticed by Shapley in 1939, a faint object coincident with the Fornax dwarf spheroidal has long been discussed as a possible sixth globular cluster system. However, deb…
