The on-axis view of GRB 170817A

, 2019
The peculiar short gamma-ray burst GRB 170817A has been firmly associated to the gravitational wave event GW170817, which has been unaninmously interpreted as due to the coalescence of a double neutron star binary.

Observed jet power and radiative efficiency of black hole candidates in the Kerr+PFDM model

European Physical Journal C: Particles and Fields
In this research, we explore the electromagnetic energy emitted by astrophysical black holes within the Kerr+PFDM (Kerr + perfect fluid dark matter) spacetime, a model comprising rotating black holes surrounded by dark matter.

Merger-driven Growth of Intermediate-mass Black Holes: Constraints from Hubble Space Telescope Imaging of Hyper-luminous X-Ray Sources

The Astrophysical Journal
Hyper-luminous X-ray sources (HLXs) are extragalactic off-nuclear X-ray sources with luminosities exceeding the theoretical limit for accretion onto stellar-mass compact objects.

Pressure-Driven Instabilities in Astrophysical Jets [PDF]

, 2008
Astrophysical jets are widely believed to be self-collimated by the hoop-stress due to the azimuthal component of their magnetic field. However this implies that the magnetic field is largely dominated by its azimuthal component in the outer jet region.

Maximum Energy of Particles in Plasmas

The Astrophysical Journal
Particles are accelerated to very high, nonthermal energies in space, solar, and astrophysical plasma environments. In cosmic-ray physics, the Hillas limit is often used as a rough estimate (or the necessary condition) of the maximum energy of particles.
