Synchrotron self-Compton Reverse Shock in Energy-Injection and Radiative Scenarios
Fraija Nissim, Betancourt-Kamenetskaia Boris, Galván Antonio +1
Gamma-ray bursts (GRBs) are among the most energetic extragalactic transients, providing a unique laboratory to investigate the physical origin of the diverse morphologies observed…
Signature of iron line profile from a Kerr-like wormhole
Cheng Liu, Hoongwah Siew, Hong-Xuan Jiang +2
Broad, skewed iron K emission lines in the X-ray spectra of accreting black holes encode key information about the spacetime geometry of the innermost disk. While the Kerr metri…
Decoding Cygnus X-2: The Critical Role of Reflection in IXPE Data
Honghui Liu, Jiachen Jiang, Adam Ingram +10
We present a spectro-polarimetric re-analysis of the first IXPE observation of Cygnus X-2 which we determine to be mainly in the normal branch, from quasi-simultaneous observations…
Stellar-Mass Black Holes
Cosimo Bambi
Stellar-mass black holes ( ) are the natural product of the evolution of heavy stars ( ). I…
About the accuracy of the relxill/relxill_nk models in view of the next generation of X-ray missions
Honghui Liu, Askar B. Abdikamalov, Temurbek Mirzaev +4
X-ray reflection spectroscopy is a powerful tool to study the strong gravity region of black holes. The next generation of astrophysical X-ray missions promises to provide unpreced…
What we can learn about compact binary mergers from their kilonova signals?
Agnieszka Janiuk, Joseph Saji, Gerardo Urrutia
Compact binary mergers are sources of gravitational waves, and can be accompanied by electromagnetic signals. We discuss the possible features in the kilonova emissions which may h…
