We test the prediction of Hamilton and Helfand (1993) that faint radio selected galaxies are a new class contributing to the diffuse X-ray background (XRB) radiation. The test is based on the correlation of X-ray optical and radio positions for sourc

We analyze late-time observations, available photometry and spectra, of a sample of type II plateau supernovae (SNe IIP). The possibility of using Hα luminosity at the nebular epoch as a tracer of 56Ni mass in this class of objects is investigated,

An asymmetry of optical emission lines that appeared in Sept. 1988 is interpreted as evidence of dust condensation within the metal-rich ejecta of SN 1987A. A quantitative analysis of this spectroscopic effect is given and shown to be compatible with

We present the results of long slit spectroscopy and deep imaging of the quasar PKS 0812+02 and its environment, obtained with the ESO 3.6m telescope using the ESO Faint Object Spectrograph and Camera (EFOSC) and the Boller and Chivens spectrograph.

From five spectrograms obtained at five different positions in the nebula, relative ionic concentrations have been derived with respect to the nucleus. They show that the degree of excitation generally decreases with distance from the nucleus. But th

The results of an 11-color photometric study of 20 globular clusters and eight open clusters in the Magellanic Clouds and three globulars in Fornax are reported. Because the photometric system is designed to measure absorption-line features in latety
