Disentangling the Galactic centre X-ray reflection signal using XMM-Newton data
K. Anastasopoulou, I. Khabibullin, E. Churazov +5
We investigate the X-ray emission from the Galactic Centre (GC) region, focusing on the 6.4 keV fluorescent line of neutral or weakly ionised iron, which is commonly attributed to…
Study of the excess Fe XXV line emission in the central degrees of the Galactic centre using XMM-Newton data
K. Anastasopoulou, G. Ponti, M. C. Sormani +14
The diffuse Fe XXV (6.7 keV) line emission observed in the Galactic ridge is widely accepted to be produced by a superposition of a large number of unresolved X-ray point sources.…
A Common Central Engine for Long Gamma Ray Bursts and Type Ib/c Supernovae?
E. Sobacchi, J. Granot, O. Bromberg +1
Long-duration, spectrally-soft Gamma-Ray Bursts (GRBs) are associated with Type Ic Core Collapse (CC) Supernovae (SNe), and thus arise from the death of massive stars. In the colla…
Kink Instability of Force-Free Jets: a Parameter Space Study
E. Sobacchi, Y. E. Lyubarsky, M. C. Sormani
In the paradigm of magnetic acceleration of relativistic jets, one of the key points is identifying a viable mechanism to convert the Poynting flux into the kinetic energy of the p…
A model for periodic blazars
Emanuele Sobacchi, Mattia C. Sormani, Antonio Stamerra
We describe a scenario to explain blazar periodicities with timescales of few years. The scenario is based on a binary super-massive black hole (SMBH) system in which one of…
