Multi-wavelength VLA observations of two extended radio galaxies, 0235-197 and 1203+043 are presented. There is some evidence from earlier studies that these two sources exhibit low frequency (

Radio astronomy has seen major advances in both instrumentation and scientific discovery during the last three years. This report is not encyclopedic but is intended to show the breadth of activity in the field. Division X is a technique-based divisi
On the 100th anniversary of Marconi's successful experiment on radio broadcasting, 250 astronomers from all over the world met in Bologna (Italy) for five days, to update their knowledge of the physics and statistical properties of powerful extragala

This is the second paper based on the 408 MHz monitoring program with the East-West arm of the Bologna interferometer. The monitoring concerned 125 radio sources measured approximately once a month for 15 years. We present the summary of the variabil

VLA 5-GHz and MERLIN 408-MHz observations of a sample of steep-spectrum low-frequency-variable sources are presented. The radio observations show that the vast majority of sources have linear sizes typical of the compact steep spectrum sources. A cla

Let me start with a short historical excursion, taking the Bologna University as an example. The Bologna University was founded in 1088, but only at the beginning of 1700, when a deep transformation in the tradition and female behaviour model occurre

We have performed a statistical analysis of a sample of 408 MHz variable sources with low-frequency VLBI data. The purpose of the investigation is a test of the refractive interstellar scintillation theory and the determination of parameters of the i

There have been many advances in radio astronomy during the last three years, and a sample of these are highlighted in the following Report. The coverage of all facets of radio astronomy is certainly not uniform, because much of the text has been pro

We present preliminary results from imaging and spectroscopy of a complete sample of radio quasars selected from the B2 survey. The optical data, which provide us information on the environment around the quasars, as well as the redshifts, allow us t
