Stellar kinematics of dwarf galaxies from multi-epoch spectroscopy: application to Triangulum II
Rachel Buttry, Andrew B. Pace, Sergey E. Koposov +9
We present new MMT/Hectochelle spectroscopic measurements for 257 stars observed along the line of sight to the ultra-faint dwarf galaxy Triangulum II. Combining with results from…
Two-Point Separation Functions for Modeling Wide Binary Systems in Nearby Dwarf Galaxies
Christopher Kervick, Matthew G. Walker, Jorge Peñarrubia +1
We use a geometric method to derive (two-dimensional) separation functions amongst pairs of objects within populations of specified position function $\mathrm{d} N/\mathrm{d} \vec{…
Spectroscopic Confirmation of the Sixth Globular Cluster in the Fornax Dwarf Spheroidal Galaxy
Andrew B. Pace, Matthew G. Walker, Sergey E. Koposov +5
The Fornax dwarf spheroidal galaxy has an anomalous number of globular clusters, five, for its stellar mass. There is a longstanding debate about a potential sixth globular cluster…
Dynamical masses and mass-to-light ratios of resolved massive star clusters -- II. Results for 26 star clusters in the Magellanic Clouds
Ying-Yi Song, Mario Mateo, John I. Bailey +5
We present spectroscopy of individual stars in 26 Magellanic Cloud (MC) star clusters with the aim of estimating dynamical masses and -band mass-to-light () ratios over a…
