Origin of 10(15)-10(16) G magnetic fields in the central engine of gamma ray bursts
(IOP PUBLISHING LTD, 2010)
Various authors have suggested that the gamma-ray burst (GRB) central engine is a rapidly rotating, strongly magnetized, (similar to 10(15)-10(16) G) compact object. The strong magnetic field can accelerate and collimate ...
MeV-GeV γ-ray telescopes probing axino LSP/gravitino NLSP as dark matter in the μνSSM
(IOP Publishing, 2020-01)
Axino and gravitino are promising candidates to solve the dark matter (DM) problem in the framework of supersymmetry. In this work, we assume that the axino is the lightest supersymmetric particle (LSP), and therefore ...
Non-thermal processes around accreting galactic black holes
(EDP Sciences, 2010-09)
Context. Accreting black holes in galactic X-ray sources are surrounded by hot plasma. The innermost part of these systems is likely a corona with different temperatures for ions and electrons. In the so-called low-hard ...
Secluded and putative flipped dark matter and Stueckelberg extensions of the standard model
(Iop Publishing Ltd, 2018-02-01)
We consider here three dark matter models with the gauge symmetry of the standard model plus an additional local U(1)(D) factor. One model is truly secluded and the other two models begin flipped, but end up secluded. All ...
Neutrinos from accreting neutron stars
(IOP Publishing, 2003-12)
The magnetospheres of accreting neutron stars develop electrostatic gaps with huge potential drops. Protons and ions, accelerated in these gaps along the dipolar magnetic field lines to energies greater than 100 TeV, can ...
