Evidence for 3XMM J185246.6+003317 as a massive magnetar with a low magnetic field
Rodrigues, Claudia V.; de Lima, Rafael C. R.; Pereira, Jonas P. +10 more
3XMM J185246.6+003317 is a transient magnetar located in the vicinity of the supernova remnant Kes79. So far, observations have only set upper limits to its surface magnetic field and spindown, and there is no estimate for its mass and radius. Using ray-tracing modelling and Bayesian inference for the analysis of several light curves spanning a pe…
A multiwavelength study of the most distant gamma-ray detected BL Lacertae object 4FGL J1219.0+3653 (z = 3.59)
Domínguez, A.; Gallego, J.; Cardiel, N. +3 more
BL Lac objects are a class of jetted active galactic nuclei that do not exhibit or have weak emission lines in their optical spectra. Recently, the first γ-ray emitting BL Lac beyond
The challenge of identifying INTEGRAL sources on the Galactic plane
Ubertini, Pietro; Bazzano, Angela; Fiocchi, Mariateresa +6 more
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 sources that populate our Universe at soft γ-ray energies. The latest IBIS/ISGRI survey lists 929 hard X-ray sources, of which 113 are reported as unidentified, i.e. lacking a…
