Spectroscopic analysis of Milky Way outer halo satellites: Aquarius II and Bootes II
Jordan Bruce, Ting S. Li, Andrew B. Pace +3
In this paper we present a chemical and kinematic analysis of two ultra-faint dwarf galaxies (UFDs), Aquarius II (Aqu~II) and \text{Boötes II} (Boo~II), using Magellan/IMACS spectr…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
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…
Dynamical Masses and Mass-to-light Ratios of Resolved Massive Star Clusters. I. NGC 419 and NGC 1846
Ying-Yi Song, Mario Mateo, A. D. Mackey +4
As an introduction of a kinematic survey of Magellanic Cloud (MC) star clusters, we report on the dynamical masses and mass-to-light () ratios of NGC 419 (SMC) and NGC 1846 (L…
Detailed Chemical Abundances in the r-Process-Rich Ultra-Faint Dwarf Galaxy Reticulum 2
Ian U. Roederer, Mario Mateo, John I. Bailey +10
The ultra-faint dwarf galaxy Reticulum 2 (Ret 2) was recently discovered in images obtained by the Dark Energy Survey. We have observed the four brightest red giants in Ret 2 at hi…
Determining the local dark matter density with LAMOST data
Qiran Xia, Chao Liu, Shude Mao +7
Measurement of the local dark matter density plays an important role in both Galactic dynamics and dark matter direct detection experiments. However, the estimated values from prev…
Degeneracies in triple gravitational microlensing
Ying-Yi Song, Shude Mao, Jin H. An
We study microlensing light curves by a triple lens, in particular, by a primary star plus two planets. A four-fold degeneracy is confirmed in the light curves, similar to the clos…
