The Outburst Decay of the Low Magnetic Field Magnetar SWIFT J1822.3-1606: Phase-resolved Analysis and Evidence for a Variable Cyclotron Feature
Guillermo A. Rodríguez Castillo, Gian Luca Israel, Andrea Tiengo +12
We study the timing and spectral properties of the low-magnetic field, transient magnetar SWIFT J1822.3-1606 as it approached quiescence. We coherently phase-connect the observatio…
The central engine of GRB 130831A and the energy breakdown of a relativistic explosion
M. De Pasquale, S. R. Oates, J. L. Racusin +37
Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, yet the nature and physical properties of their energy sources are far from understood. Very important clu…
Polarization of neutron star surface emission: a systematic analysis
Roberto Taverna, Roberto Turolla, Denis Gonzalez Caniulef +3
New-generation X-ray polarimeters currently under development promise to open a new window in the study of high-energy astrophysical sources. Among them, neutron stars appear parti…
Magnetars: the physics behind observations
Roberto Turolla, Silvia Zane, Anna Watts
Magnetars are the strongest magnets in the present universe and the combination of extreme magnetic field, gravity and density makes them unique laboratories to probe current physi…
The X-ray outburst of the Galactic Centre magnetar SGR J1745-2900 during the first 1.5 year
F. Coti Zelati, N. Rea, A. Papitto +17
In 2013 April a new magnetar, SGR 1745-2900, was discovered as it entered an outburst, at only 2.4 arcsec angular distance from the supermassive black hole at the Centre of the Mil…
