Hunting for extreme high-energy-peaked BL Lacs: Rare to find and difficult to classify
Loredana Bassani, Raffaella Landi, Nicola Masetti
We explore the possible existence of a new population of BL Lacs, called ultra extreme high-energy-peaked BL Lacs (UEHBLs), whose synchrotron emission component peaks in the MeV ba…
The challenge of identifying INTEGRAL sources on the Galactic plane
Raffaella Landi, Loredana Bassani, Gabriele Bruni +6
The International Gamma-ray Astrophysics Laboratory (INTEGRAL) has been surveying the sky above 20 keV since its launch in 2002 providing new insights into the nature of the source…
Update of the INTEGRAL/IBIS AGN catalogue: deeper on the Galactic plane and wider beyond
A. Malizia, L. Bassani, R. Landi +7
In this work we have updated the list of AGN detected by INTEGRAL taking into account the new objects listed in the last published INTEGRAL/IBIS survey. We have collected 83 new AG…
Investigating the X-ray counterparts to unidentified sources in the 1000-orbit INTEGRAL/IBIS catalogue
R. Landi, L. Bassani, A. Bazzano +6
The latest INTEGRAL/IBIS all-sky survey lists 219 hard X-ray sources whose nature is still unknown. We report on our ongoing campaign aimed at identifying these high-energy emitter…
The nature of fifty Palermo Swift-BAT hard X-ray objects through optical spectroscopy
A. F. Rojas, N. Masetti, D. Minniti +16
We present the nature of 50 hard X-ray emitting objects unveiled through an optical spectroscopy campaign performed at seven telescopes in the northern and southern hemispheres. Th…
Looking for blazars in a sample of unidentified high-energy emitting Fermi sources
E. J. Marchesini, N. Masetti, V. Chavushyan +12
Context. Based on their overwhelming dominance among associated Fermi gamma ray catalogue sources, it is expected that a large fraction of the unidentified Fermi objects are blazar…
