Limiting Light Dark Matter with Luminous Hadronic Loops
Joe Bramante, Melissa Diamond, Christopher V. Cappiello +1
Dark matter is typically assumed not to couple to the photon at tree level. While annihilation to photons through quark loops is often considered in indirect detection searches, su…
Multimessenger Constraints on Radiatively Decaying Axions from GW170817
Melissa Diamond, Damiano F. G. Fiorillo, Gustavo Marques-Tavares +2
The metastable hypermassive neutron star produced in the coalescence of two neutron stars can copiously produce axions that radiatively decay into ~MeV photons. T…
Axion-sourced fireballs from supernovae
Melissa Diamond, Damiano F. G. Fiorillo, Gustavo Marques-Tavares +1
New feebly interacting particles would emerge from a supernova core with 100-MeV-range energies and produce -rays by subsequent decays. These would contribute to the diffuse cos…
Binary Collisions of Dark Matter Blobs
Melissa D. Diamond, David E. Kaplan, Surjeet Rajendran
We describe the model-independent mechanism by which dark matter and dark matter structures heavier than GeV form binary pairs in the early Universe that spi…
Gamma-Ray Flashes from Dark Photons in Neutron Star Mergers
Melissa D. Diamond, Gustavo Marques-Tavares
In this letter we begin the study of visible dark sector signals coming from binary neutron star mergers. We focus on dark photons emitted in the 10 ms - 1 s after the merger, and…
Constraints on Relic Magnetic Black Holes
Melissa D. Diamond, David E. Kaplan
We present current direct and astrophysical limits on the cosmological abundance of black holes with extremal magnetic charge. Because they don't Hawking radiate, much lighter prim…
