We present the first results of an ambitious work still in progress. We are modeling the light distribution of a large sample (˜10000) of cluster galaxies from the WINGS survey as single Sérsic or bulge plus disk systems. Our classification scheme is based on a logical filter that takes advantage of well-known characteristics of these two kinds of

Observations of the WMAP sources were made using the AMI-SA during 14 separate observing runs between 2007 April and 2008 September. Observations of the WMAP sources using VSA were performed during 10 separate observing runs between 2007 February and 2008 July. (1 data file).

Using the Arcminute Microkelvin Imager (AMI) at 16GHz and the Very Small Array (VSA) at 33GHz to make follow-up observations of sources in the New Extragalactic WMAP Point Source catalogue, we have investigated the flux density variability in a complete sample of 97 sources over time-scales of a few months to ~1.5yr.

Extreme ultraviolet (EUV) and X-ray emission is of great importance in several phenomena related to the formation of planetary systems and the atmospheres of planets. The atmospheric composition and the mass of an exoplanet are partly dependent on the X-ray and EUV radiation received during the first stages of formation and even during main

We report the X-ray detection of Nova Vul 2007 (S. Nakano, IAUC 8861) with the Swift X-ray Telescope in a 6.7ks observation obtained on 2007 October 18 at UT 01:05. The XRT spectrum contains 192 X-ray photons and is largely consistent with a thermal plasma model with temperature kT=0.2 +0.4/-0.07 keV and absorbing column NH=(8 +2/-3)e21 cm^-2. A
