Search for the multiwavelength counterparts to extragalactic unassociated Fermi γ-ray sources
Alberto Ulgiati, Simona Paiano, Fabio Pintore +7
Aims. In this paper, we searched for multi-wavelength (X-ray, optical and radio) counterparts to the unassociated gamma-ray sources (UGS) of the Fermi 4FGL-DR4 catalog. The main go…
Changing Look of the optical spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
Simona Paiano, Renato Falomo, Aldo Treves +2
Following the high activity of the gamma-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we obtained optical spectr…
Swift X-Ray and UV Observations of six Gaia Binaries supposedly containing a Neutron Star
B. Sbarufatti, F. Coti Zelati, A. Marino +3
Recent observations have led to the discovery of numerous optically selected binaries containing an undetected component with mass consistent with a compact object (neutron star or…
Spectroscopy of a Sample of Unidentified Gamma-ray Fermi Sources
Alberto Ulgiati, Simona Paiano, Aldo Treves +5
The fourth-DR3 version (4FGL-DR3) of the Fermi/LAT catalogue of -ray sources contains 1000 objects at a galactic latitude |b| > 10 which are not identified with…
