The neutron star X-ray binary Aql X-1 shows quasi-periodic outbursts about once a year. These active states are relatively well covered in optical/infrared and...
Early APOGEE Chemical Results for the Milky Way Bulge
The stellar content of the bulge of the Galaxy is not well characterized yet, in part due to the high extinction and, therefore, limited access at optical...
Early Galactic Evolution of Carbon, Nitrogen and Oxygen
We present results on carbon, nitrogen, and oxygen abundances for a sample of unevolved metal-poor stars with metallicities in the range -0.3 [Fe/H] -3. Oxygen...
Early results from ChanPLaNS: Mystery of hard X-ray emitting CSPNe†
We are presently using the Chandra X-ray Observatory to conduct the first systematic X-ray survey of planetary nebulae (PNe) in the solar neighborhood. The...
Early Science Results from the UKIDSS ESO Public Survey
The first large release of data from the UKIDSS ESO public survey took place in July 2006. The size of the data set is about 7% of the size of the final survey...
Early-type Galaxies in Isolation: an HI Perspective with ATLAS 3D
We present preliminary results of our HI WSRT observations of early-type galaxies in the ATLAS3D sample. We discuss the dependence of HI properties on...
Early-type galaxies in the EGS (Fernandez Lorenzo+, 2011)
Physical parameters for 135 early-type galaxies in the Extended Groth Strip (EGS). For each galaxy equatorial coordinates, total magnitudes in B and g-bands...
Early-type galaxies: application of a new spectrophotometric population synthesis model.
The authors have applied a new spectrophotometric stellar population synthesis model, designed to study early-type galaxies (Vazdekis, Casuso et al. 1995), to...
