We present a deep, wide-field optical survey of the young stellar cluster Alpha Per, in which we have discovered a large population of candidate brown dwarfs. Subsequent infrared photometric follow-up shows that the majority of them are probable or possible members of the cluster, reaching to a minimum mass of 0.035 Msun. We have used this list of

We report the detection with the BeppoSAX Wide Field Cameras of a superburst from 4U 1254-69. The superburst is preceded by a normal type-I X-ray burst, has a decay time that is the longest of all eight superbursts detected so far and a peak luminosity that is the lowest. Like for the other seven superbursts, the origin is a well-known type-I X-ray

We have completed a survey of early-type galaxies in a region covering 700 sq. degrees with cz -20 that satisfy our isolation criteria. The sample galaxies obey the Mg-sigma relation but have a higher frequency of [OII] and [OIII] emission than found in the Fornax cluster. They appear to be younger than the ellipticals in the Fornax cluster having

We are observing two sets of Low Polarization Quasars (LPQs), one of which have low (

We present results of a CCD optical imaging survey of the ionized gas in 73 luminous elliptical and lenticular galaxies, selected from the RC3 catalog to represent a broad variety of X-ray, radio, infrared and kinematical properties. For each galaxy we have used broad-band R images and narrow-band images centered at the Hα and [NII] emission lines

We present the results of an optical imaging survey of 73 luminous early-type galaxies directed to study the properties of their interstellar medium. We have found that a large fraction of E (72%) and S0 (85%) galaxies in our sample contain a measurable amount of ionized gas. The gas morphology appears to be rather smooth; however 12% of the sample
