The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278
G. Giovannini, M. Giroletti, G. B. Taylor
We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278 with a linear resolution of < 0.1 pc. Our radio data reveal a two sided structure, with s…
The two sided parsec scale structure of the Low Luminosity Active Galactic Nucleus in NGC 4278
M. Giroletti, G. B. Taylor, G. Giovannini
We present new Very Long Baseline Interferometry observations of the LINER galaxy NGC 4278. The observations were taken with the Very Long Baseline Array (VLBA) and a single antenn…
A2255: the First Detection of Filamentary Polarized Emission in a Radio Halo
Federica Govoni, Matteo Murgia, Luigina Feretti +3
A deep radio observation of the A2255 cluster of galaxies has been carried out at 1.4 GHz with the Very Large Array synthesis telescope. Thanks to the excellent (u,v) coverage and…
The Bologna Complete Sample of Nearby Radio Sources
G. Giovannini, G. B. Taylor, L. Feretti +3
We present a new, complete, sample of 95 radio sources selected from the B2 and 3CR catalogues, with z < 0.1. Since no selection effect on the core radio power, jet velocity, or so…
Parsec scale properties of nearby BL Lacs
M. Giroletti, G. Giovannini, G. B. Taylor +1
We present new radio data completing the imaging for a sample of 30 nearby (z < 0.2) BL Lac objects on parsec and kiloparsec scale. The sample is composed of both high and low lumi…
The nature of close companions of the BL Lac Objects 1ES 0502+675 and 1ES 1440+122
G. Giovannini, R. Falomo, R. Scarpa +2
We report on deep radio images and optical spectroscopy of two BL Lac objects that have very close compact companions. The two targets, 1ES 0502+675 and 1ES 1440+122, were selected…
