Comment on ``Nonextensive theory of dark matter and gas density profiles''
Mikhail V. Medvedev
Self-gravitating systems with nonlocal, long-range interactions are described by nonextensive statistics. Recently, Leubner demonstrated that the nonextensivity parameter shoul…
Hot Radiative Accretion onto a Spinning Neutron Star
Mikhail V. Medvedev
(Abridged) A new type of self-similar hot viscous radiative accretion flow onto a rapidly spinning neutron star has recently been discovered. This ``hot brake'' flow forms in the t…
Kinetics of Particles in Relativistic Collisionless Shocks
Mikhail V. Medvedev, Luis O. Silva, Ricardo A. Fonseca +2
Charged plasma particles form an anisotropic counter-streaming distribution at the front of a shock. In the near- and ultra-relativistic regimes, Weibel (or two-stream) instability…
Limits on thermal conduction in galaxy clusters
Mikhail V. Medvedev, Adrian L. Melott, Chris Miller +1
We have calculated lower limits for the global effective thermal conductivity in a sample of 165 Abell clusters. We assumed that cluster X-ray luminosity is compensated by a conduc…
Thermal Conduction and the Stability of Hot Accretion Flows
Mikhail V. Medvedev, Ramesh Narayan
Recently, Medvedev & Narayan (2001) discovered a new type of accretion flow, a hot settling flow around a rapidly rotating neutron star. The flow is cooling-dominated and energetic…
Constraints on SIDM with flavor mixing
Mikhail Medvedev
The self-interacting dark matter (SIDM) model with flavor mixing (astro-ph/0010616) was proposed to resolve problems of the CDM model on small scales by keeping attractive features…
