MADHAT: Model-Agnostic Dark Halo Analysis Tool

1 code implementation7 Oct 2019 Kimberly K. Boddy, Stephen Hill, Jason Kumar, Pearl Sandick, Barmak Shams Es Haghi

We present the Model-Agnostic Dark Halo Analysis Tool (MADHAT), a numerical tool which implements a Fermi-LAT data-driven, model-independent analysis of gamma-ray emission from dwarf satellite galaxies and dwarf galaxy candidates due to dark matter annihilation, dark matter decay, or other nonstandard or unknown astrophysics.

Effective $J$-factors for Milky Way dwarf spheroidal galaxies with velocity-dependent annihilation

1 code implementation29 Sep 2019 Kimberly K. Boddy, Jason Kumar, Andrew B. Pace, Jack Runburg, Louis E. Strigari

Due to the assumptions made in our gamma-ray data analysis, our bounds are comparable to previous bounds on both the $p$-wave and Sommerfeld-enhanced cross sections using dSphs.

Constraints on Dark Matter Microphysics from the Milky Way Satellite Population

1 code implementation22 Apr 2019 Ethan O. Nadler, Vera Gluscevic, Kimberly K. Boddy, Risa H. Wechsler

Alternatives to the cold, collisionless dark matter (DM) paradigm in which DM behaves as a collisional fluid generically suppress small-scale structure.

Disentangling Dark Physics with Cosmic Microwave Background Experiments

1 code implementation26 Jun 2018 Zack Li, Vera Gluscevic, Kimberly K. Boddy, Mathew S. Madhavacheril

The constraints benefit from a wide survey, and show gradual improvement for instrumental noise levels from 10 $\mu$K-arcmin to 1 $\mu$K-arcmin and resolution from 5 arcmin to 1 arcmin.

Model-independent constraints on dark matter annihilation in dwarf spheroidal galaxies

1 code implementation11 Feb 2018 Kimberly K. Boddy, Jason Kumar, Danny Marfatia, Pearl Sandick

We present a general, model-independent formalism for determining bounds on the production of photons in dwarf spheroidal galaxies via dark matter annihilation, applicable to any set of assumptions about dark matter particle physics or astrophysics.
