A Tour of the Direct Detection Landscape
Neal Weiner - New York University (NYU)
A wide range of results have led to a confusing situation in the area of direct WIMP detection. I'll review the status of these results. The features of the results imply that almost any explanation will require a departure from standard assumptions (Maxwellian halo, elastic WIMP scattering or… -
Dark Matter Annihilation: From High Redshift to the Galactic Center
Doug Finkbeiner - Harvard University
The existence of dark matter is hardly in doubt, yet astrophysicists continue to search in vain for any non-gravitational signals of it. In the case of weakly interacting massive particle (WIMP) models, ongoing annihilation or decay of WIMPs to Standard Model particles could provide observable… -

Dark Matter Halos in 6D
Lawrence Widrow - Queen's University
I will describe various efforts to understand the phase space structure of dark matter halos. Implications for dark matter detection experiments will also be discussed. -
Our Self-Annihilating Neighbours
James Taylor - University of Waterloo
One of the most exciting, albeit slightly speculative, components of the Fermi mission is to search for evidence of energetic events related to dark matter decay or annihilation. The best targets for this search a regions where we suspect there is dark matter, but see few conventional gamma-ray… -
Constraints on Dark Matter Models from a Fermi-LAT Search for Cosmic-Ray Electrons from the Sun
Jennifer Siegal-Gaskins - Ohio State University
No known astrophysical mechanisms are expected to generate a significant high-energy flux of cosmic-ray electrons and positrons (CREs) from the Sun. However, some recently considered classes of dark matter models predict such a signal. We analyzed the CRE events collected by the Fermi-LAT during its… -
Astrophysical Constraints on Dark Matter Annihilation with Sommerfeld Enhancement
Jesus Zavala Franco - University of Iceland
Dark matter models with an annihilation cross section enhanced by a Sommerfeld mechanism have been proposed in the past years to explain a number of observed anomalies, such as the excess of high energy positrons in cosmic rays reported by PAMELA. However, this enhancement can not be arbitrarily… -
Substructure, Sommerfeld, and CR Signals
Tracy Slatyer - Massachusetts Institute of Technology (MIT) - Department of Physics
Models of dark matter with Sommerfeld-enhanced annihilation have been proposed to explain the CR excess observed by the PAMELA and Fermi experiments. In such models, the local annihilation signal can easily be dominated by small, dense, cold subhalos, instead of by the smooth DM halo as usually… -
What Dark Matter Microhalos Can Tell us About Reheating
Adrienne Erickcek - University of North Carolina at Chapel Hill
The expansion history of the Universe before big bang nucleosynthesis is unknown; in many models, the Universe was effectively matter-dominated between the end of inflation and the onset of radiation domination. I will show how an early matter-dominated era leaves an imprint on the small-scale… -
Revealing the Invisible: Strong Gravitational Lensing & Particle Dark Matter
Leonidas Moustakas - California Institute of Technology
The particular properties of different dark matter particle candidates can lead to different properties and distributions of sub-structure within galaxies; structure that may uniquely be probed through specific state of the art observations of galaxy-scale dark matter halos that happen to be acting… -
Certainty And Uncertainty In Dark Matter Searches
Departing from the context of CoGeNT and COUPP, two direct searches for WIMP dark matter, we will inspect the recent landscape of anomalies observed by these and several other detectors. The aim of this talk is to communicate an appreciation for the subtleties inherent to experimental efforts in… -
Status of the XENON100 Dark Matter Search
Guillaume Plante - Columbia University
The XENON100 detector, currently taking data at the Laboratori Nazionali del Gran Sasso in Italy, is a dual-phase xenon time projection chamber used to search for dark matter by simultaneously measuring the scintillation and ionization signals produced by nuclear recoils. These two signals allow the…
