A Vast Thin Plane of Co-rotating Dwarf Galaxies Orbiting the Andromeda Galaxy
Rodrigo A. Ibata, Geraint F. Lewis, Anthony R. Conn +13
Dwarf satellite galaxies are thought to be the remnants of the population of primordial structures that coalesced to form giant galaxies like the Milky Way. An early analysis noted…
Evolution of the Bar Fraction in COSMOS: Quantifying the Assembly of the Hubble Sequence
Kartik Sheth, Debra Meloy Elmegreen, Bruce G. Elmegreen +13
We have analyzed the redshift-dependent fraction of galactic bars over 0.2<z<0.84 in 2,157 luminous face-on spiral galaxies from the COSMOS 2-square degree field. Our sample is an…
Revised metallicity classes for low-mass stars: dwarfs (dM), subdwarfs (sdM), extreme subdwarfs (esdM), and ultra subdwarfs (usdM)
Sebastien Lepine, R. Michael Rich, Michael M. Shara
The current classification system of M stars on the main sequence distinguishes three metallicity classes (dwarfs - dM, subdwarfs - sdM, and extreme subdwarfs - esdM). The spectros…
The Bulge Radial Velocity Assay (BRAVA): I. Techniques and a Rotation Curve
R. Michael Rich, David B. Reitzel, Christian D. Howard +1
We are undertaking a large scale radial velocity survey of the Galactic bulge which uses M giant stars selected from the 2MASS catalog as targets for the CTIO 4m Hydra multi-object…
Number Counts of GALEX Sources in FUV (1530A) and NUV (2310A) Bands
C. Kevin Xu, Jose Donas, Stephane Arnouts +21
Number Counts of galaxies in two GALEX bands (FUV: 1530A and NUV: 2310A, both in AB magnitudes) are reported. They provide for the first time in the literature homogeneously calibr…
Draco 119: A Remarkable Heavy Element-deficient Giant
Jon. P. Fulbright, R. Michael Rich, Sandra Castro
We report the abundance analysis of new high S/N spectra of the most metal-poor ([Fe/H] ) star presently known to be a member of a dwarf galaxy, the Draco dSph red giant,…
