Table main gives the names, coordinates (J2000), epoch, proper motions, and optical (BjRI) and near-infrared (JHKs) magnitudes for new, red proper motion objects published in this paper. Table obslog1 provides the observing logs for a subset of proper motion objects observed photometrically with FORS1 and ISAAC on the VLT. It includes observing

The site survey for the Advanced Technology Solar Telescope concluded recently after more than 2 years of data gathering and analysis. Six locations, including lake, island, and continental sites, were thoroughly probed for image quality and sky brightness. The present paper describes the analysis methodology employed to determine the height

We present new medium-band uvby Strömgren and broadband VI photometry for the central regions of the globular cluster ω Cen. From this photometry we have obtained differential reddening estimates relative to two other globular clusters (M13 and NGC 288) using a metallicity-independent, reddening-free temperature index, [c]≡(u-v)-(v-b)-0.2(b-y), for

The process of $ u ar{ u}$ radiation from a relativistic plasma of electrons and positrons is studied within the Random Phase Approximation.

Spectroscopic redshifts for 102 galaxies in the central region of the galaxy cluster Abell 2744 are presented. For each galaxy equatorial coordinates and radial velocity are given. (1 data file).
