Periodic Gamma-ray Modulation of the blazar PG 1553+113 Confirmed by Fermi-LAT and Multi-wavelength Observations
S. Abdollahi, L. Baldini, G. Barbiellini +98
A 2.1-year periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in almost 7 year of data from the Fermi Large Area Tele…
Unraveling the Origins of GRB X-ray Plateaus through a Study of X-ray Flares
H. Dereli-Bégué, A. Pe'er, D. Bégué +1
The X-ray light curves of gamma-ray bursts (GRBs) display complex features, including plateaus and flares, that challenge theoretical models. Here, we study the properties of flare…
Failed-Transition outbursts in Black hole low-mass X-ray binaries
K. Alabarta, D. Altamirano, M. Méndez +6
Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst. Based on the X-ray spectrum and variability, this evolution can be divided into three canonic…
Can jets make the radioactively powered emission from neutron star mergers bluer?
Lorenzo Nativi, Mattia Bulla, Stephan Rosswog +5
Neutron star mergers eject neutron-rich matter in which heavy elements are synthesised. The decay of these freshly synthesised elements powers electromagnetic transients ("macronov…
Bayesian Time-Resolved Spectroscopy of GRB Pulses: -Intensity Correlation
Hüsne Dereli Bégué, Hoi-Fung Yu, Felix Ryde
Gamma-ray bursts (GRBs) show different behaviours and trends in their spectral evolution. One of the methods used to understand the physical origin of these behaviours is to study…
Observations of a GX 301-2 Apastron Flare with the X-Calibur Hard X-Ray Polarimeter Supported by NICER, the Swift XRT and BAT, and Fermi GBM
Q. Abarr, M. Baring, B. Beheshtipour +28
The accretion-powered X-ray pulsar GX 301-2 was observed with the balloon-borne X-Calibur hard X-ray polarimeter during late December 2018, with contiguous observations by the NICE…
