Most well-known results regarding the distribution of dark matter in the Universe are based upon dissipationless simulations of the cosmological evolution of dark matter only. I will discuss some generic ways in which baryonic processes alter the distribution of dark matter. I will begin with a discussion of the clustering of dark matter on few Mpc scales. Baryonic effects can alter dark...
The center of the Milky Way is predicted to be the brightest source of gamma rays produced by dark matter. An excess consistent with a dark matter annihilation signal has been observed in the data collected by Fermi LAT. Although these results are intriguing, the complexity involved in modeling the foreground and background emission from conventional astrophysical sources makes a conclusive...
I will describe recent progress in structure formation and galaxy formation simulations. I will demonstrate that recent large-scale simulations are able to reproduce the observed galaxy population on large scales. Based on those simulations I will then present results on the dark matter distribution in galaxies and discuss implications for dark matter detection experiments. At the end of my...
Current and upcoming 21-cm measurements during the cosmic dawn can provide a new arena on the search for the cosmological dark matter. This era saw the formation of the first stars, which coupled the spin temperature of hydrogen to its kinetic temperature---producing 21-cm absorption in the CMB. The strength of this absorption acts as a thermostat, showing us if the baryons have been...
The cosmic microwave background has provided the most precise measurement of the dark matter (DM) abundance, and places stringent limits on its annihilation cross section. Yet, its nature remains unknown, motivating the exploration of non-standard models. In this talk I will discuss the imprints that such non-standard DM candidates may leave on CMB spectral distortions and anisotropy...
