On the change of old neutron star masses with galactocentric distance gr-qc astro-ph.HE hep-ph nucl-th We show that the pulsar mass depends on the environment, and that it decreases going towards the center of the Milky Way. This is due to two combined effects, the capture and accumulation of self-interacting, non-...

How to avoid collisions in 3D-realizations for moving graphs math.CO If we parameterize the positions of all vertices of a given graph in the plane such that distances between adjacent vertices are fixed, we obtain a moving graph. An L-linkage is a realization of a moving graph in 3D-space, by representing edges us...

Shadow of a black hole surrounded by dark matter gr-qc We consider a simple spherical model consisting of a Schwarzschild black hole of mass $M$ and a dark matter of mass $\Delta M$ around it. The general formula for the radius of black-hole shadow has been derived in this case. It is shown that the change of the s...
