R. M. Rich, M. L. M. Collins, C. M. Black +4
NGC 4449 is a nearby Magellanic irregular starburst galaxy with a B-band absolute magnitude of -18 and a prominent, massive, intermediate-age nucleus at a distance from Earth of 3.…
The Bulge Radial Velocity Assay (BRAVA): II. Complete Sample and Data Release
Andrea Kunder, Andreas Koch, R. Michael Rich +13
We present new radial velocity measurements from the Bulge Radial Velocity Assay (BRAVA), a large scale spectroscopic survey of M-type giants in the Galactic bulge/bar region. The…
The Stellar and Gaseous Contents of the Orion Dwarf Galaxy
John M. Cannon, Korey Haynes, Hans Most +5
We present new KPNO 0.9-m optical and VLA HI spectral line observations of the Orion dwarf galaxy. This nearby (D ~ 5.4 Mpc), intermediate-mass (M_dyn = 1.1x10^10 Solar masses) dwa…
