Axion Emission Can Explain a New Hard -ray Excess from Nearby Isolated Neutron Stars
Malte Buschmann, Raymond T. Co, Christopher Dessert +1
Axions may be produced thermally inside the cores of neutron stars (NSs), escape the stars due to their feeble interactions with matter, and subsequently convert into X-rays in the…
Characterizing the Nature of the Unresolved Point Sources in the Galactic Center
Laura J. Chang, Siddharth Mishra-Sharma, Mariangela Lisanti +3
The Galactic Center Excess (GCE) of GeV gamma rays can be explained as a signal of annihilating dark matter or of emission from unresolved astrophysical sources, such as millisecon…
Early-Universe Simulations of the Cosmological Axion
Malte Buschmann, Joshua W. Foster, Benjamin R. Safdi
Ultracompact dark matter (DM) minihalos at masses at and below arise in axion DM models where the Peccei-Quinn (PQ) symmetry is broken after inflation. The min…
Direct Acceleration: Cosmic and Exoplanet Synergies
David Erskine, Alex Kim, Eric Linder +10
Direct measurement of acceleration is a key scientific goal for both cosmology and exoplanets. For cosmology, the concept of redshift drift (more than 60 years old by the 2020s) co…
Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider
Juliette Alimena, James Beacham, Martino Borsato +198
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Had…
