Dwarf Galaxies in CDM, WDM, and SIDM: Disentangling Baryons and Dark Matter Physics
Alex Fitts, Michael Boylan-Kolchin, Brandon Bozek +9
We present a suite of FIRE-2 cosmological zoom-in simulations of isolated field dwarf galaxies, all with masses of M at , across a r…
Warm FIRE: Simulating Galaxy Formation with Resonant Sterile Neutrino Dark Matter
Brandon Bozek, Alex Fitts, Michael Boylan-Kolchin +8
We study the impact of a warm dark matter (WDM) cosmology on dwarf galaxy formation through a suite of cosmological hydrodynamical zoom-in simulations of $M_{\rm halo} \approx10^{1…
Dispersal of tidal debris in a Milky-Way-sized dark matter halo
Wayne Ngan, Raymond G. Carlberg, Brandon Bozek +3
We simulate the tidal disruption of a collisionless N-body globular star cluster in a total of 300 different orbits selected to have galactocentric radii between 10 and 30 kpc in f…
Properties of Resonantly Produced Sterile Neutrino Dark Matter Subhalos
Shunsaku Horiuchi, Brandon Bozek, Kevork N. Abazajian +4
The anomalous 3.55 keV X-ray line recently detected towards a number of massive dark matter objects may be interpreted as the radiative decays of 7.1 keV mass sterile neutrino dark…
Resonant Sterile Neutrino Dark Matter in the Local and High-z Universe
Brandon Bozek, Michael Boylan-Kolchin, Shunsaku Horiuchi +3
Sterile neutrinos comprise an entire class of dark matter models that, depending on their production mechanism, can be hot, warm, or cold dark matter. We simulate the Local Group a…
Simulating tidal streams in a high resolution dark matter halo
Wayne Ngan, Brandon Bozek, Raymond G. Carlberg +3
We simulate tidal streams in the presence and absence of substructures inside the zero redshift snapshot of the Via Lactea II (VL-2) simulation. A halo finder is used to remove and…
Galaxy UV-luminosity function and reionization constraints on axion dark matter
Brandon Bozek, David J. E. Marsh, Joseph Silk +1
If the dark matter (DM) were composed of axions, then structure formation in the Universe would be suppressed below the axion Jeans scale. Using an analytic model for the halo mass…
The Dark Matter Contribution to Galactic Diffuse Gamma Ray Emission
Lin F. Yang, Joseph Silk, Alexander S. Szalay +3
Observations of diffuse Galactic gamma ray emission (DGE) by the Fermi Large Area Telescope (LAT) allow a detailed study of cosmic rays and the interstellar medium. However, diffus…
Luminous Satellites versus Dark Subhaloes: Clustering in the Milky Way
Brandon Bozek, Rosemary F. G. Wyse, Gerard Gilmore
The observed population of the Milky Way satellite galaxies offer a unique testing ground for galaxy formation theory on small-scales. Our novel approach was to investigate the clu…
Curvature Constraints from the Causal Entropic Principle
Brandon Bozek, Andreas Albrecht, Daniel Phillips
Current cosmological observations indicate a preference for a cosmological constant that is drastically smaller than what can be explained by conventional particle physics. The Cau…
Exploring Parameter Constraints on Quintessential Dark Energy: the Inverse Power Law Model
Mark Yashar, Brandon Bozek, Augusta Abrahamse +2
We report on the results of a Markov Chain Monte Carlo (MCMC) analysis of an inverse power law (IPL) quintessence model using the Dark Energy Task Force (DETF) simulated data sets…
A measure of the impact of future dark energy experiments based on discriminating power among quintessence models
Michael Barnard, Augusta Abrahamse, Andreas Albrecht +2
We evaluate the ability of future data sets to discriminate among different quintessence dark energy models. This approach gives an alternative measure for assessing the impact of…
Exploring Parameter Constraints on Quintessential Dark Energy: The Exponential Model
Brandon Bozek, Augusta Abrahamse, Andreas Albrecht +1
We present an analysis of a scalar field model of dark energy with an exponential potential using the Dark Energy Task Force (DETF) simulated data models. Using Markov Chain Monte…
Exploring Parameter Constraints on Quintessential Dark Energy: the Pseudo-Nambu Goldstone Boson Model
Augusta Abrahamse, Andreas Albrecht, Michael Barnard +1
We analyze the constraining power of future dark energy experiments for Pseudo-Nambu Goldstone Boson (PNGB) quintessence. Following the Dark Energy Task Force methodology, we forec…
Exploring Parameter Constraints on Quintessential Dark Energy: the Albrecht-Skordis model
Michael Barnard, Augusta Abrahamse, Andreas Albrecht +2
We consider the effect of future dark energy experiments on ``Albrecht-Skordis'' (AS) models of scalar field dark energy using the Monte-Carlo Markov chain method. We deal with the…
