Challenges of Relativistic Astrophysics
Reuven Opher
I discuss some of the most outstanding challenges in relativistic astrophysics in the subjects of: compact objects (Black Holes and Neutron Stars); dark sector (Dark Matter and Dar…
The Effect of a Single Supernova Explosion on the Cuspy Density Profile of a Small-Mass Dark Matter Halo
Rafael S. de Souza, Luiz Felippe S. Rodrigues, Emille E. O. Ishida +1
Some observations of galaxies, and in particular dwarf galaxies, indicate a presence of cored density profiles in apparent contradiction with cusp profiles predicted by dark matter…
Generalized Non-Commutative Inflation
U. D. Machado, R. Opher
Non-commutative geometry indicates a deformation of the energy-momentum dispersion relation for massless particles. This distorted energy-momentum…
A large change in the predicted number of small halos due to a small amplitude oscillating inflaton potential
Luiz Felippe S. Rodrigues, Reuven Opher
A smooth inflaton potential is generally assumed when calculating the primordial power spectrum, implicitly assuming that a very small oscillation in the inflaton potential creates…
Random Primordial Magnetic Fields and the Gas Content of Dark Matter Halos
Rafael S. de Souza, Luiz Felippe S. Rodrigues, Reuven Opher
We recently predicted the existence of random primordial magnetic fields (RPMF) in the form of randomly oriented cells with dipole-like structure with a cell size and an aver…
Are the magnetic fields of millisecond pulsars ~ 10^8 G?
Rafael S. de Souza, Reuven Opher
It is generally assumed that the magnetic fields of millisecond pulsars (MSPs) are G. We argue that this may not be true and the fields may be appreciably greater. We…
