Truncated, Tilted Discs as a Possible Source of Quasi-Periodic Oscillations
A. Deepika Bollimpalli, P. Chris Fragile, W. Janosz Dewberry +1
Many accreting black holes and neutron stars exhibit rapid variability in their X-ray light curves, termed quasi-periodic oscillations (QPOs). The most commonly observed type is th…
Effect of geometrically thin discs on precessing, thick flows: Relevance to type-C QPOs
D. A. Bollimpalli, P. C. Fragile, W. Kluźniak
Type-C quasi-periodic oscillations (QPOs) are the low-frequency QPOs most commonly observed during the hard spectral state of X-ray binary systems. The leading model for these QPOs…
Accretion disc backflow in resistive MHD simulations
R. Mishra, M. Čemeljić, W. Kluźniak
We investigate accretion onto a central star, with the size, rotation rate, and magnetic dipole of a young stellar object, to study the flow pattern (velocity and density) of the f…
A deep spectromorphological study of the -ray emission surrounding the young massive stellar cluster Westerlund 1
F. Aharonian, H. Ashkar, M. Backes +156
Young massive stellar clusters are extreme environments and potentially provide the means for efficient particle acceleration. Indeed, they are increasingly considered as being res…
Time-resolved hadronic particle acceleration in the recurrent Nova RS Ophiuchi
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +171
Recurrent Novae are repeating thermonuclear explosions in the outer layers of white dwarfs, due to the accretion of fresh material from a binary companion. The shock generated by e…
Levitating atmospheres around naked singularities
Ronaldo S. S. Vieira, Włodek Kluźniak
For a wide class of spherically symmetric naked singularities there is a sphere within which gravity is effectively repulsive. In such spacetimes accreting matter cannot reach the…
Diffuse Galactic gamma-ray emission with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +225
Diffuse -ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over sev…
HESS J1818-154, a new composite supernova remnant discovered in TeV gamma rays and X-rays
H. E. S. S. Collaboration, A. Abramowski, F. Aharonian +217
Composite supernova remnants (SNRs) constitute a small subclass of the remnants of massive stellar explosions where non-thermal radiation is observed from both the expanding shell-…
