Analytic solutions to the accretion of a rotating finite cloud towards a central object - II. Schwarzschild spacetime

We construct a general relativistic model for the accretion flow of a rotating finite cloud of non-interacting particles infalling onto a Schwarzschild black hole. The streamlines start at a spherical...

An ultra-high-energy cosmic ray (UHECR) colliding with the Earth's atmosphere gives rise to an Extensive Air Shower (EAS). Due to different charge separation mechanisms within the thin shower front co...
Spin and spin-isospin instabilities in asymmetric nuclear matter at zero and finite temperatures using Skyrme functionals
Spin spin-isospin instabilities asymmetric nuclear matter at zero finite temperatures

Self-consistent mean field methods based on phenomenological Skyrme effective interactions are
known to exhibit spurious spin and spin-isospin instabilities both at zero and finite temperatures when ...

An unexpected distribution of temperatures in the CosmicMicrowave Background (CMB) could be
a sign of new physics. In particular, the existence of cosmic defects could be indicated by temperature dis...

Conventional equilibrium statistical mechanics of open gravitational systems is known to be problematical. We first recall that spherical stars/galaxies acquire unbounded radii, become infinitely mass...
