Conversations and Deliberations: Non-Standard Cosmological Epochs and Expansion Histories
Brian Batell, Keith R. Dienes, Brooks Thomas +17
This document summarizes the discussions which took place during the PITT-PACC Workshop entitled "Non-Standard Cosmological Epochs and Expansion Histories," held in Pittsburgh, Pen…
Structure formation with primordial black holes: collisional dynamics, binaries, and gravitational waves
M. Sten Delos, Antti Rantala, Sam Young +1
Primordial black holes (PBHs) could compose the dark matter content of the Universe. We present the first simulations of cosmological structure formation with PBH dark matter that…
Detecting dark objects with plasma microlensing by their gravitational wakes
M. Sten Delos
A moving mass makes a gravitational wake in the partially ionized interstellar medium, which acts as a lens for radio-frequency light. Consequently, plasma microlensing could compl…
Limits on Early Matter Domination from the Isotropic Gamma-Ray Background
Himanish Ganjoo, M. Sten Delos
In cosmologies with hidden sector dark matter, the lightest hidden sector species can come to dominate the energy budget of the universe and cause an early matter-dominated era (EM…
