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…
Stellar Kinematics in the Complicated Inner Spheroid of M31: Discovery of Substructure Along the Southeastern Minor Axis and its Relationship to the Giant Southern Stream
Karoline M. Gilbert, Mark Fardal, Jasonjot S. Kalirai +9
We present the discovery of a kinematically-cold stellar population along the SE minor axis of the Andromeda galaxy (M31) that is likely the forward continuation of M31's giant sou…
The DEEP2 Galaxy Redshift Survey: Redshift Identification of Single-Line Emission Galaxies
E. N. Kirby, P. Guhathakurta, S. M. Faber +3
We present two methods for determining spectroscopic redshifts of galaxies in the DEEP2 survey which display only one identifiable feature, an emission line, in the observed spectr…
AEGIS: Galaxy Spectral Energy Distributions from the X-Ray to Radio
N. P. Konidaris, P. Guhathakurta, K. Bundy +15
The All-wavelength Extended Groth Strip International Survey (AEGIS) team presents broad-band spectral energy distributions (SEDs), from X-ray to radio wavelengths, for 71 galaxies…
