Spheroidal force-free neutron star magnetospheres

Jérôme Pétri

Abridged. Fast rotating and self-gravitating astrophysical objects suffer strong deformations from centrifugal forces. If moreover they are magnetized, they generate an electromagn…

High-energy neutrinos from X-rays flares of blazars frequently observed by the Swift X-Ray Telescope

S. I. Stathopoulos, M. Petropoulou, P. Giommi +3

Blazar flares have been suggested as ideal candidates for enhanced neutrino production. While the neutrino signal of -ray flares has been widely discussed, the neutrino yield of…

New XMM-Newton observations of faint, evolved supernova remnants in the Large Magellanic Cloud

P. J. Kavanagh, M. Sasaki, M. D. Filipovic +5

The Large Magellanic Cloud (LMC) hosts a rich population of supernova remnants (SNRs), our knowledge of which is the most complete of any galaxy. However, there remain many candida…

Radio emission from colliding outflows in high-mass X-ray binaries with strongly magnetized neutron stars

Margaritis Chatzis, Maria Petropoulou, Georgios Vasilopoulos

We present a toy model for radio emission in HMXBs with strongly magnetized neutron stars (NS) where a wind-collision region is formed by the NS outflow and the stellar wind of the…

Spheroidal magnetic stars rotating in vacuum

Jérôme Pétri

Gravity shapes stars to become almost spherical because of the isotropic nature of gravitational attraction in Newton's theory. However, several mechanisms break this isotropy like…

Multi-wavelength observations of the Blazar 4C +28.07

Davit Zargaryan, Jonathan Mackey, Thibault Barnouin +1

The active galactic nucleus 4C +28.07 is a flat spectrum radio quasar, one of the brightest at -ray energies. We study its multi-wavelength emission by analysing year…
