... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

Central Astronomical Observatory at Pulkovo of Russian Academy of Sciences PUL Analysis Center Pulkovo IVS Analysis Center (PUL) 2009 Annual Rep ort Zinovy Malkin, Natalia Miller, Elena Popova Abstract This report briefly presents the PUL IVS Analysis Center activities during 2009 and plans for the coming year. The main topics of the investigations of PUL staff in that period were ICRF related studies, computation and analysis of EOP series, and VLBI2010 related issues. ...

The NICFPS:FPCalibrate script allows you to take Fabry-P rot calibration data. The script takes a sequence of images over a range of Fabry-P rot etalon positions, as specified in a file. The file format is as follows: . Zero or more lines of X Y Z etalon positions, in steps: . ... Here is a short sample file: # Data for the NICFPS:FPCalibrate script # x y z position (integer steps) 0 0 0 100 -25 33 . ... Input File : select a file containing lines of X Y Z etalon positions. ...

... The GW from coalescing compact binaries composed of NS and BH are the best understood of all astrophysical GW sources. A conservative lower limit to the event rate of galactic binary neutron star coalescence of about 1 per 100000 year follows from double pulsar   statistics studies (Narayan et al. ... In Figure  47 we show the rates of coalescence of binary WD and NS in a model elliptical galaxy   consisting of stars, depending on time elapsed since the (assumed instantaneous) star formation. ...
