Seeking the nearest neutron stars using a new local electron density map
Joseph Bramante, Katherine Mack, Nirmal Raj +2
Neutron stars provide a compelling testing ground for gravity, nuclear dynamics, and physics beyond the Standard Model, and so it will be useful to locate the neutron stars nearest…
Dark Matter Candidates and Searches
Nassim Bozorgnia, Joseph Bramante, James M. Cline +7
Astrophysical observations suggest that most of the matter in the cosmos consists of a new form that has not been observed on Earth. The nature and origin of this mysterious dark m…
Dimming Starlight with Dark Compact Objects
Joseph Bramante, Melissa D. Diamond, J. Leo Kim
We demonstrate a new technique to search for dark compact objects. When dark matter comprising a dark compact object interacts with photons, the compact object can disperse light t…
Loosely Bound Composite Dark Matter
Javier F. Acevedo, Yilda Boukhtouchen, Joseph Bramante +3
We investigate loosely bound composite states made of dark matter, where the binding energy for constituent particles is less than the constituent mass. We focus on models of nucle…
Mineral Detection of Neutrinos and Dark Matter 2024. Proceedings
Sebastian Baum, Patrick Huber, Patrick Stengel +57
The second "Mineral Detection of Neutrinos and Dark Matter" (MDvDM'24) meeting was held January 8-11, 2024 in Arlington, VA, USA, hosted by Virginia Tech's Center for Neutrino Phys…
Cosmology of self-replicating universes in black holes formed by dark matter-seeded stellar collapse
Joseph Bramante, Nirmal Raj
We show that dark matter with certain minimal properties can convert the majority of baryons in galaxies to black holes over hundred trillion year timescales. We argue that this ha…
Dissipative Dark Cosmology: From Early Matter Dominance to Delayed Compact Objects
Joseph Bramante, Christopher V. Cappiello, Melissa D. Diamond +3
We demonstrate a novel mechanism for producing dark compact objects and black holes through a dark sector, where all the dark matter can be dissipative. Heavy dark sector particles…
Neutrino and Gamma-Ray Signatures of Inelastic Dark Matter Annihilating outside Neutron Stars
Javier F. Acevedo, Joseph Bramante, Qinrui Liu +1
We present a new inelastic dark matter search: neutron stars in dark matter-rich environments capture inelastic dark matter which, for interstate mass splittings between about $45…
