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…
Probing the nova shock physics with future gamma-ray observations of the upcoming outburst from T Coronae Borealis
Liu, Ruo-Yu; Zheng, Jian-He; Zhang, Hai-Ming +2 more
Nova shocks behave like scaled-down supernova remnant shocks with a lifetime of only a few weeks or months, thereby providing a unique opportunity to study the dynamics of non-relativistic shocks as well as the shock acceleration physics. Recently, GeV and TeV gamma-ray emissions from an outburst of the recurrent nova RS Ophiuchi have been observe…
