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 optical
This is a summary of the 2013 release of the plasma simulation code Cloudy. Cloudy models the ionization, chemical, and thermal state of material that may be exposed to an external radiation field or
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,
The VLT-UVES survey for molecular hydrogen in high-redshift damped Lyman-alpha systems
We have searched for molecular hydrogen in damped Lyman-alpha (DLA) and sub-DLA systems at z>1.8 using UVES at the VLT. Out of the 33 systems in our sample, 8 have firm and 2 have tentative
A deep search for 21-cm absorption in high redshift damped Lyman-alpha systems
We present deep GMRT 21-cm absorption spectra of 10 damped Lyman- systems (DLAs), of which 8 are at redshifts z> 1:3. HI absorption was detected in only one DLA, the z= 0:5318 absorber toward PKS
Resolved Galaxies in the Hubble Ultra Deep Field: Star Formation in Disks at High Redshift
The photometric redshift distributions, spectral types, Sersic indices, and sizes of all resolved galaxies in the Hubble Space Telescope Ultra Deep Field (UDF) are studied in order to understand the
Lithium abundances of the local thin disc stars
Lithium abundances are presented for a sample of 181 nearby F and G dwarfs with accurate Hipparcos parallaxes. The stars are on circular orbits about the Galactic centre and, hence, are identified as
Discovery of a short orbital period in the Supergiant Fast X-ray Transient IGR J16479–4514
We report here the discovery of a 3.32 d orbital period in the Supergiant Fast X-ray Transient (SFXT) source IGR J16479−4514. Using the long-term light curve of this source obtained with Swift Burst
Filling factors and scale heights of the diffuse ionized gas in the Milky Way
The combination of dispersion measures of pulsars, distances from the model of Cordes & Lazio (2002) and emission measures from the WHAM survey enabled a statistical study of electron densities and
A search for H i 21 cm absorption in strong Mg ii absorbers in the redshift desert
We report results from a deep search for redshifted H I 21 cm absorption in 55 strong Mg IIλ2796 absorbers (having W λ2796 0 > 0.5 A) at intermediate redshifts, 0.58 3σ significance in 32 other Mg II
