Reopening the window on charged dark matter
Leonid Chuzhoy, Edward W. Kolb
We reexamine the limits on charged dark matter particles. We show that if their mass and charge fall in the range 100(q_X/e)^2< m_X < 10^8(q_X/e) TeV, then magnetic fields prevent…
Impact of Dark Matter Annihilation on the High-Redshift Intergalactic Medium
Leonid Chuzhoy
We reexamine the impact of dark matter (DM) annihilation on the intergalactic medium, taking into account the clumping of DM particles. We find that energy injection from the annih…
Can ambipolar diffusion solve the cosmic lithium problem?
Leonid Chuzhoy
Recent WMAP observations indicate that the primordial abundance of lithium should have been 2-4 times higher than the value measured in low-metallicity stars. We show that this dis…
The structure of dark matter halos: self-similar models versus N-body simulations
Leonid Chuzhoy
We derive the density profile of cold dark matter halos using a self-similar accretion model. We show that if the clumpiness of the infalling matter is taken into account, then the…
