The Least Luminous Galaxy: Spectroscopy of the Milky Way Satellite Segue 1
Marla Geha, Beth Willman, Josh D. Simon +4
We present Keck/DEIMOS spectroscopy of Segue 1, an ultra-low luminosity (M_V = -1.5) Milky Way satellite companion. While the combined size and luminosity of Segue 1 are consistent…
BH Accretion in Low-Mass Galaxies Since z~1
Yong Shi, George Rieke, Jennifer Donley +3
We have selected a sample of X-ray emitting active galactic nuclei (AGNs) in low-mass host galaxies (5e9-2e10 Msun) out to z~1. By comparing to AGNs in more massive hosts, we have…
Metallicity and Alpha-Element Abundance Measurement in Red Giant Stars from Medium Resolution Spectra
Evan N. Kirby, Puragra Guhathakurta, Christopher Sneden
We present a technique that applies spectral synthesis to medium resolution spectroscopy (MRS, R ~ 6000) in the red (6300 A < lambda < 9100 A) to measure [Fe/H] and [alpha/Fe] of i…
