Optical spectroscopic observations of low-energy counterparts of Fermi-LAT gamma-ray sources
H. A. Peña-Herazo, R. A. Amaya-Almazán, F. Massaro +15
A significant fraction of all -ray sources detected by the Large Area Telescope aboard the \fer\ satellite is still lacking a low-energy counterpart. In addition, there is still…
The 3CR extragalactic survey at high redshift
A. Jimenez-Gallardo, F. Massaro, M. A. Prieto +13
We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with during Cycle 20 in the redshift range between 1.5 and 2…
Optical spectroscopic observations of gamma-ray blazar candidates. IX. Optical archival spectra and further observations from SOAR and OAGH
H. A. Peña-Herazo, F. Massaro, V. Chavushyan +11
Nearly one-third of the sources in the -LAT catalogs lack a lower energy counterpart, hence being referred as unidentified/unassociated gamma-ray sources (UGSs). In order to…
BAT AGN Spectroscopic Survey -- XV: The High Frequency Radio Cores of Ultra-hard X-ray Selected AGN
Krista Lynne Smith, Richard F. Mushotzky, Michael Koss +14
We have conducted 22 GHz radio imaging at 1" resolution of 100 low-redshift AGN selected at 14-195 keV by the Swift-BAT. We find a radio core detection fraction of 96%, much higher…
