MiXDM: Cosmic Ray Signals from Multiple States of Dark Matter
Ilias Cholis, Neal Weiner
Recent data from cosmic ray experiments such as PAMELA, Fermi, ATIC and PPB-BETS all suggest the need for a new primary source of electrons and positrons at high (>~100 GeV) energi…
The Fermi Haze: A Gamma-Ray Counterpart to the Microwave Haze
Gregory Dobler, Douglas P. Finkbeiner, Ilias Cholis +2
The Fermi Gamma-Ray Space Telescope reveals a diffuse inverse Compton signal in the inner Galaxy with a similar spatial morphology to the microwave haze observed by WMAP, supportin…
Hydrodynamical Response of a Circumbinary Gas Disk to Black Hole Recoil and Mass Loss
Lia R. Corrales, Zoltán Haiman, Andrew MacFadyen
Finding electromagnetic (EM) counterparts of future gravitational wave (GW) sources would bring rich scientific benefits. A promising possibility, in the case of the coalescence of…
A New Approach to Searching for Dark Matter Signals in Fermi-LAT Gamma Rays
Spencer Chang, Lisa Goodenough
Several cosmic ray experiments have measured excesses in electrons and positrons, relative to standard backgrounds, for energies from ~ 10 GeV - 1 TeV. These excesses could be due…
On discrepancy between ATIC and Fermi data
Dmitry Malyshev
Either ATIC or Fermi-LAT data can be fitted together with the PAMELA data by three components: primary background ~ E^{-3.3}, secondary background ~ E^{-3.6}, and an additional sou…
A Dynamical Model for the Evolution of a Pulsar Wind Nebula inside a Non-Radiative Supernova Remnant
Joseph D. Gelfand, Patrick O. Slane, Weiqun Zhang
A pulsar wind nebula inside a supernova remnant provides a unique insight into the properties of the central neutron star, the relativistic wind powered by its loss of rotational e…
