Deficiency of Broad Line AGNs in Compact Groups of Galaxies
M. A. Martinez, A. del Olmo, R. Coziol +1
Based on a new survey of AGN activity in Compact Groups of Galaxies, we report a remarkable deficiency of Broad Line AGNs as compared to Narrow Line AGNs. The cause of such deficie…
Nuclear Activity in UZC Compact Groups of Galaxies
M. A. Martinez, A. del Olmo, P. Focardi +1
We analyse the level of nuclear activity in galaxies belonging to UZC-CGs. Spectra are available for 868 galaxies (90% of the whole catalog); 67 % of them show nuclear activity (AG…
Detection of optical linear polarization in the SN2006aj/XRF060218 non-spherical expansion
J. Gorosabel, V. Larionov, A. J. Castro-Tirado +10
We have performed optical polarimetric observations of the SN2006aj associated to the X-ray flash (XRF) of February 18, 2006, XRF060218 that provide information on its expansion ge…
