We find a significant number of massive and compact galaxies in clusters from the ESO Distant Clusters Survey (EDisCS) at 0.4 z 1. They have similar stellar masses, ages, sizes, and axial ratios to local z ~ 0.04 compact galaxies in WIde field Nearby Galaxy clusters Survey (WINGS) clusters, and to z = 1.4-2 massive and passive galaxies found in

We review some recent developments which make use of the concept of `superstatistics', an effective description for nonequilibrium systems with a varying intensive parameter such as the inverse temperature. We describe how the asymptotic decay of stationary probability densities can be determined using a variational principle, and present some new

We report on observations of 11 transit events of the transiting extrasolar planet XO-1b by the SuperWASP North observatory. From our data, obtained during 2004 May-September, we find that the XO-1b orbital period is 3.941634 +/- 0.000137 days, the planetary radius is 1.34RJ +/- 0.12RJ, and the inclination is 88.92d +/- 1.04d, in good agreement

We discuss here the results obtained in the determination of effective temperatures and metallicities of late-type stars. We provide the abundances of MgH, TiI and TiII, with a list of selected lines, for the red giant of Arcturus and the metal-poor K subdwarf G 224-58 A. The Sun was used as a template star. After computing synthetic spectra for

In its most general acceptation, surface photometry is a technique applicable to any "extended" object, irrespective of the spectral band of the observational frame. The subject of this paper is restricted to the mapping of galaxies in the "standard" bands of the visible. By combining CCD images with deep large-field photographs, this technique

An X-ray burst from the direction of the neutron star (NS) transient and thermonuclear burster KS 1741-293 triggered the Swift-BAT on 2011-09-01 at 12:07:22 UTC. The burst was detected only in the 15-25 keV band, lasted for about 10s, had a peak flux of (9.0+/-2.5)e-9 ergs/cm^2/s and an integrated fluence of (5.5+/-1.2)e-8 erg/cm^2 (both in the 15
