Molecular Chemistry for Dark Matter III: DarkKROME
Michael Ryan, Sarah Shandera, James Gurian +1
Dark matter that is dissipative may cool sufficiently to form compact objects, including black holes. Determining the abundance and mass spectrum of those objects requires an accur…
Molecular Chemistry for Dark Matter II: Recombination, Molecule Formation, and Halo Mass Function in Atomic Dark Matter
James Gurian, Donghui Jeong, Michael Ryan +1
Dissipative dark matter predicts rich observable phenomena that can be tested with future large-scale structure surveys. As a specific example, we study atomic dark matter, consist…
Molecular Chemistry for Dark Matter
Michael Ryan, James Gurian, Sarah Shandera +1
Molecular cooling is essential for studying the formation of sub-structure of dissipative dark-matter halos that may host compact objects such as black holes. Here, we analyze the…
Gauge-Invariant Tensor Perturbations Induced from Baryon-CDM Relative Velocity and the B-mode Polarization of the CMB
James Gurian, Donghui Jeong, Jai-chan Hwang +1
At second-order, scalar perturbations can source traceless and transverse perturbations to the metric, called induced gravitational waves (IGW). The apparent gauge-dependence of th…
