New bounds on light scalars from the tip of the red giant branch
Natnael Debru, Audrey Fung, Saniya Heeba +3
Light, weakly coupled particles can be copiously produced in the hot and dense interior of stars, and the resulting energy loss can leave observable imprints on entire stellar popu…
Asteroseismological constraints on--and hints of--dark matter interactions
Stephanie Beram, Aaron C. Vincent
If dark matter interacts with nuclei or electrons, then elastic collisions with constituents of stars will cause some of the galactic dark matter to fall below the escape velocity…
Refining the sensitivity of new physics searches with ancient minerals
Audrey Fung, Thalles Lucas, Levente Balogh +2
Paleodetection has been proposed as a competitive method for detecting dark matter and other new physics interactions, complementing conventional direct detection experiments. In t…
Simulation of thermal conduction by asymmetric dark matter in realistic stars and planets
Hannah Banks, Stephanie Beram, Rashaad Reid +1
Dark matter captured in stars can act as an additional heat transport mechanism, modifying fusion rates and asteroseismoloigcal observables. Calculations of heat transport rates re…
Boxed in from all sides: a global fit to loopy dark matter and neutrino masses
Karen Macías Cárdenas, Gopolang Mohlabeng, Aaron C. Vincent
We investigate a dark matter model that couples to the standard model through a one-loop interaction with neutrinos, where the mediator particles also generate neutrino masses. We…
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…
Dark matter limits from the tip of the red giant branch of globular clusters
Haozhi Hong, Aaron C. Vincent
Capture and annihilation of WIMP-like dark matter in red giant stars can lead to faster-than-expected ignition of the helium core, and thus a lower tip of the red giant branch (TRG…
Constraints on Heavy Asymmetric and Symmetric Dark Matter from the Glashow Resonance
Qinrui Liu, Ningqiang Song, Aaron C. Vincent
The decay of asymmetric dark matter (ADM) can lead to distinct neutrino signatures characterized by an asymmetry between neutrinos and antineutrinos. In the high-energy regime, the…
Resonant or asymmetric: The status of sub-GeV dark matter
Sowmiya Balan, Csaba Balázs, Torsten Bringmann +9
Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the strong constraints on heavier DM candidates but at the same time face a multitude of new constr…
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…
Cosmic Ray-Boosted Dark Matter at IceCube
Christopher Cappiello, Qinrui Liu, Gopolang Mohlabeng +1
Cosmic ray (CR) upscattering of dark matter is considered as one of the most straightforward mechanisms to accelerate ambient dark matter, making it detectable at high threshold, l…
New bounds on light millicharged particles from the tip of the red-giant branch
Audrey Fung, Saniya Heeba, Qinrui Liu +3
Stellar energy loss is a sensitive probe of light, weakly coupled dark sectors, including ones containing millicharged particles (MCPs). The emission of MCPs can affect stellar evo…
