A redshifted excess in the broad emission lines after the flare of the -ray narrow-line Seyfert 1 PKS 2004-447
W. Hon, M. Berton, E. Sani +6
PKS 2004-447 is a narrow-line Seyfert 1 (NLS1) harbouring a relativistic jet with gamma-ray emission. On 2019-10-25, the Fermi-Large Area Telescope captured a -ray flare from th…
BASS XXXIX: Swift-BAT AGN with changing-look optical spectra
Matthew J. Temple, Claudio Ricci, Michael J. Koss +13
Changing-look (CL) AGN are unique probes of accretion onto supermassive black holes (SMBHs), especially when simultaneous observations in complementary wavebands allow investigatio…
Multi-wavelength observations of the Galactic X-ray binaries IGR J20155+3827 and Swift J1713.4-4219
F. Onori, M. Fiocchi, N. Masetti +4
In recent years, thanks to the continuous surveys performed by INTEGRAL and Swift satellites, our knowledge of the hard X-ray/soft gamma-ray sky has greatly improved. As a result i…
Optical spectroscopic classification of 35 hard X-ray sources from the Swift-BAT 70-month catalogue
E. J. Marchesini, N. Masetti, E. Palazzi +15
The nature of a substantial percentage (about one fifth) of hard X-ray sources discovered with the BAT instrument onboard the Neil Gehrels Swift Observatory (hereafter Swift) is un…
Identification of newly-discovered sources belonging to the 4th IBIS catalog and to the 54 months Palermo Swift/BAT catalog
P. Parisi, N. Masetti, A. F. Rojas +17
The most recent all-sky surveys performed with the INTEGRAL and SWIFT satellites allowed the detection of more than 1500 sources in hard X-rays above 20 keV. About one quarter of t…
