Two-integral distribution functions in axisymmetric galaxies
Mihael Petač, Piero Ullio
Izvirni znanstveni članek
Oznake: dark matter;astrophysics of galaxies;high energy physics;phenomenology;
We address the problem of reconstructing the phase-space distribution function for an extended collisionless system, with known density profile and in equilibrium within an axisymmetric gravitational potential. Assuming that it depends on only two integrals of motion, namely the energy and the compo ...

On velocity-dependent dark matter annihilations in dwarf satellites
Mihael Petač, Piero Ullio, Mauro Valli
Izvirni znanstveni članek
Oznake: dark matter;indirect detection;dwarf satellites;sommerfeld enhancement;gamma-rays;
Milky Way dwarf spheroidal satellites are a prime target for Dark Matter (DM) indirect searches. There have been recent reassessments of the expected DM gamma-ray signals in case of long-range interactions, commonly known as Sommerfeld enhancement. Since details of the underlying DM phase-space dist ...
