The census of nuclear activity of late-type galaxies in the Virgo cluster
R. Decarli, G. Gavazzi, I. Arosio +4
The first spectroscopic census of AGNs associated to late-type galaxies in the Virgo cluster is carried on by observing 213 out of a complete set of 237 galaxies more massive than…
Spectro-photometry of galaxies in the Virgo cluster
Giuseppe Gavazzi, Christian Bonfanti, Gerry Sanvito +2
As a result of an extensive observational campaign targeting the Virgo cluster, we obtained integrated (drift-scan mode) optical spectra and multiwavelength (UV,U,B,V,H) photometry…
The filament of ionized gas in the outskirt of M87
G. Gavazzi, A. Boselli, J. M. Vilchez +2
We report on the filament of ionized gas found at the NE periphery of M87, the second brightest elliptical galaxy in the Virgo cluster. The object lies at 3.16 arcmin (15.7 kpc) pr…
Optical spectroscopy of galaxies in the direction of the Virgo cluster
G. Gavazzi, C. Bonfanti, P. Pedotti +2
Optical spectroscopy of 76 galaxies, 48 of which are projected in the direction of the Virgo cluster and 28 onto the Coma-A1367 supercluster, is reported. Adding these new measurem…
