The eleventh and twelfth data releases of the Sloan Digital Sky Survey: final data from SDSS-III
The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed opticalExpand
The mass of the neutron star in Vela X-1 and tidally induced non-radial oscillations in GP Vel
We report new radial velocity observations of GP Vel / HD 77581, the optical companion to the eclipsing X-ray pulsar Vela X-1. Using data spanning more than two complete orbits of the system, weExpand
The evolution of stellar mass and the implied star formation history
We present a compilation of measurements of the stellar mass density as a function of redshift. Using this stellar mass history we obtain a star formation history and compare it to the instantaneousExpand
Structure and Kinematics of the Stellar Halos and Thick Disks of the Milky Way Based on Calibration Stars from Sloan Digital Sky Survey DR7
The structure and kinematics of the recognized stellar components of the Milky Way are explored, based on well-determined atmospheric parameters and kinematic quantities for 32360 "calibration stars"Expand
The Australia Telescope Compact Array Broadband Backend (CABB): Description & First Results ⋆
Here we describe the Compact Array Broadband Backend (CABB) and present first results obtained with the upgraded Australia Telescope Compact Array (ATCA). The 16-fold increase in observing bandwidth,Expand
Zero-metallicity stars I. Evolution at constant mass
We present extensive evolutionary models of stars with initial zero-metallicity, covering a large range of initial masses (i.e. 0:7 M M 100 M). Calculations are carried out at constant mass, withExpand
We present the properties of an extensive sample of molecular clouds in the Large Magellanic Cloud (LMC) mapped at 11?pc resolution in the CO(1-0) line. Targets were chosen based on a limiting COExpand
Are the Narrow-Line Regions in Active Galaxies Dusty and Radiation Pressure Dominated?
The remarkable similarity between emission spectra of narrow-line regions (NLRs) in Seyfert galaxies has long presented a mystery. In photoionization models, this similarity implies that theExpand
A New Red Giant-based Distance Modulus of 13.3 Mpc to the Antennae Galaxies and Its Consequences
The Antennae galaxies are the closest example of an ongoing major galaxy merger and, as such, represent a unique laboratory for furthering the understanding of the formation of exotic objects (e.g.,Expand
Molecules at z = 0.89 - A 4-mm-rest-frame absorption-line survey toward PKS 1830−211
We present the results of a 7 mm spectral survey of molecular absorption lines originating in the disk of a z = 0.89 spiral galaxy located in front of the quasar PKS 1830-211. Our survey wasExpand
