There is morphological evidence that the activity in powerful radio galaxies could be triggered by mergers and galaxy interactions. However, nothing is known about the timescales, order of events, and the type of interaction involved. It is not yet known whether there exists an evolutionary link between radio galaxies and other merger systems such

This abstract details the engineering processes used in the overall landing site selection process. The performance of the landing RADAR, IMU, thrusters and robustness of the lander structure to slopes and rocks drive safety concerns.

We review the progress of ESO/WFI Imaging and VLT/FLAMES spectroscopy of large numbers of individual stars in nearby dwarf spheroidal galaxies by the Dwarf galaxy Abundances and Radial-velocities Team (DART). These observations have allowed us to show that neither the kinematics nor the abundances nor the spatial distributions are easy to explain

Aims.Our aim in this paper is to present an explanatory scenario for the formation of the observed relatively metal rich globular clusters associated with the thick disc of the Galaxy, distinct from the mode of formation of the lower metallicity halo clusters.Methods.The observations to be accounted for here are the two peaks in the metallicity

Point sources detections in J, H and K obtained along the TCS-CAIN survey in the 530 recorded Galactic fields. Individual magnitudes for each point source in the three bands, their coordinates (both equatorial and galactic ones), and cross-matching with 2MASS sources is provided in each catalogue file. Each file corresponds to a single field

We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary systems with component masses between 3 and 20M&sun;. Optimally oriented binaries with distances up to 1 Mpc could be detected with efficiency of at least 90%. We found no
