Identification of two new HMXBs in the LMC: a 2013 s pulsar and a probable SFXT
G. Vasilopoulos, C. Maitra, F. Haberl +2
We report on the X-ray and optical properties of two high-mass X-ray binary systems located in the Large Magellanic Cloud (LMC). Based on the obtained optical spectra, we classify…
X-ray mapping of the stellar wind in the binary PSR J2032+4127/MT91 213
M. Petropoulou, G. Vasilopoulos, I. M. Christie +2
PSR J2032+4127 is a young and rapidly rotating pulsar on a highly eccentric orbit around the high-mass Be star MT91 213. X-ray monitoring of the binary system over a 4000 day…
Plasmoid statistics in relativistic magnetic reconnection
M. Petropoulou, I. M. Christie, L. Sironi +1
Plasmoids, quasi-spherical regions of plasma containing magnetic fields and high-energy particles, are a self-consistent by-product of the reconnection process in the relativistic…
Collapsar Gamma-Ray Bursts: how the luminosity function dictates the duration distribution
Maria Petropoulou, Rodolfo Barniol Duran, Dimitrios Giannios
Jets in long-duration -ray bursts (GRBs) have to drill through the collapsing star in order to break out of it and produce the -ray signal while the central engine is still a…
Point-source and diffuse high-energy neutrino emission from Type IIn supernovae
Maria Petropoulou, Stefan Coenders, Georgios Vasilopoulos +2
Type IIn supernovae (SNe), a rare subclass of core collapse SNe, explode in dense circumstellar media that have been modified by the SNe progenitors at their last evolutionary stag…
Radio Emission from Sgr A*: Pulsar Transits Through the Accretion Disc
Ian Christie, Maria Petropoulou, Petar Mimica +1
Radiatively inefficient accretion flow models have been shown to accurately account for the spectrum and luminosity observed from Sgr A* in the X-ray regime down to mm wavelengths.…
