Nuclear Kinetic Equilibrium During Big Bang Nucleosynthesis

Samuel D. McDermott, Michael S. Turner

Sasankan et al, have recently claimed that there are significant deviations in the phase-space distributions of the kinetic energies of nuclei from the Maxwell-Boltzmann form usual…

A Deeply Bound Dibaryon is Incompatible with Neutron Stars and Supernovae

Samuel D. McDermott, Sanjay Reddy, Srimoyee Sen

We study the effect of a dibaryon, S, in the mass range 1860 MeV < m_S < 2054 MeV, which is heavy enough not to disturb the stability of nuclei and light enough to possibly be cosm…

Constraining Dissipative Dark Matter Self-Interactions

Rouven Essig, Samuel D. McDermott, Hai-Bo Yu +1

We study the gravothermal evolution of dark matter halos in the presence of dissipative dark matter self-interactions. Dissipative interactions are present in many particle-physics…

WIMPflation

Dan Hooper, Gordan Krnjaic, Andrew J. Long +1

We propose a class of models in which a stable inflaton is produced as a thermal relic in the early universe and constitutes the dark matter. We show that inflaton annihilations ca…

Robust Constraints and Novel Gamma-Ray Signatures of Dark Matter That Interacts Strongly With Nucleons

Dan Hooper, Samuel D. McDermott

Due to shielding, direct detection experiments are in some cases insensitive to dark matter candidates with very large scattering cross sections with nucleons. In this paper, we re…

Severely Constraining Dark Matter Interpretations of the 21-cm Anomaly

Asher Berlin, Dan Hooper, Gordan Krnjaic +1

The EDGES Collaboration has recently reported the detection of a stronger-than-expected absorption feature in the global 21-cm spectrum, centered at a frequency corresponding to a…
