New blazars from the cross-match of recent multi-frequency catalogs
A. Maselli, F. Massaro, R. D'Abrusco +4
Blazars are radio-loud active galactic nuclei well known for their non thermal emission spanning a wide range of frequencies. The Roma-BZCAT is, to date, the most comprehensive lis…
Refining the associations of the Fermi Large Area Telescope Source Catalogs
F. Massaro, R. D'Abrusco, M. Landoni +10
The Fermi-Large Area Telescope (LAT) First Source Catalog (1FGL) was released in February 2010 and the Fermi-LAT 2-Year Source Catalog (2FGL) appeared in April 2012, based on data…
Optical spectroscopic observations of blazars and gamma-ray blazar candidates in the Sloan Digital Sky Survey Data Release Nine
F. Massaro, N. Masetti, R. D'Abrusco +2
We present an analysis of the optical spectra available in the Sloan Digital Sky survey data release nine (SDSS DR9) for the blazars listed in the ROMA-BZCAT and for the gamma-ray…
The low-frequency radio catalog of flat spectrum sources
F. Massaro, M. Giroletti, R. D'Abrusco +5
A well known property of the gamma-ray sources detected by COS-B in the 1970s, by the Compton Gamma-ray Observatory in the 1990s and recently by the Fermi observations is the prese…
Unveiling the nature of the unidentified gamma-ray sources VI: gamma-ray blazar candidates in the WISH survey and their radio properties
M. Nori, M. Giroletti, F. Massaro +4
According to the second Fermi LAT Catalog (2FGL), about one third of the gamma-ray sources listed have no assigned counterparts at lower energies. Many statistical methods have bee…
