An X-Ray Burst from a Magnetar Enlightening the Mechanism of Fast Radio Bursts
M. Tavani, C. Casentini, A. Ursi +60
Fast radio bursts (FRBs) are short (millisecond) radio pulses originating from enigmatic sources at extragalactic distances so far lacking a detection in other energy bands. Magnet…
The XMM deep survey in the CDFS XI. X-ray properties of 185 bright sources
K. Iwasawa, A. Comastri, C. Vignali +11
We present X-ray spectra of 185 bright sources detected in the XMM-Newton deep survey of the Chandra Deep Field South, combining the three EPIC cameras. The 2-10 keV flux limit of…
Gamma-Ray and X-Ray Observations of the Periodic-Repeater FRB 180916 During Active Phases
M. Tavani, F. Verrecchia, C. Casentini +33
FRB 180916 is a most intriguing source at 150 Mpc distance capable of producing repeating fast radio bursts with a periodic 16.35 day temporal pattern. We report on the X-ray and $…
The Open Universe survey of Swift-XRT GRB fields: a complete sample of HBL blazars
P. Giommi, Y. L. Chang, S. Turriziani +22
We have analysed all the X-ray images centred on Gamma Ray Bursts generated by Swift over the last 15 years using automatic tools that do not require any expertise in X-ray astrono…
Unravelling the complex behavior of Mrk 421 with simultaneous X-ray and VHE observations during an extreme flaring activity in April 2013
MAGIC collaboration, V. A. Acciari, S. Ansoldi +237
We report on a multi-band variability and correlation study of the TeV blazar Mrk 421 during an exceptional flaring activity observed from 2013 April 11 to 2013 April 19. The study…
Probing the circumnuclear absorbing medium of the buried AGN in NGC 1068 through NuSTAR observations
A. Zaino, S. Bianchi, A. Marinucci +9
We present the results of the latest NuSTAR monitoring campaign of the Compton-thick Seyfert 2 galaxy NGC 1068, composed of four 50 ks observations performed between July 201…
