New Structures in Galactic Disks: Predictions and Discoveries
Our main goal is to review: 1) some physical mechanisms which form the observed structures in galactic disks; 2) the discovery of new galactic structures...
Synthetic horizontal branch (HB) stars in globular clusters, when computed on the basis of HB evolutionary tracks and pulsation theory constraints, furnish the...
New technologies for the Tenerife Microwave Spectrometer and current status
The Tenerife Microwave Spectrometer (TMS) is part of a renewed effort to study and characterize the CMB frequency distribution. The spectrometer is based on a...
New ultra-cool dwarfs from SDSS and 2MASS (Zhang+, 2009)
SDSS and 2MASS photometry of 129 ultra-cool dwarf candidates. The photometric data are from the seventh Data Release of the SDSS Photometric and the 2MASS All...
The authors present VI CCD photometry for nine fields towards the centre of NGC 1851 covering an area of 22×22 arcmin2, out to 1.2 tidal radii. These were...
