Constraining axion quadratic couplings with the Hulse-Taylor binary system
Ziwen Yin, Shyam Balaji, Malcolm Fairbairn +1
The orbital evolution of the Hulse-Taylor binary neutron star system is described to high precision by general relativity, in which gravity is the only long-range force and gravita…
A Solar Probe of Dark Matter Decay in the Galaxy
Maximilian Detering, Shyam Balaji
Dark matter (DM) particles decaying in the Galactic halo can inject energetic that inverse-Compton scatter (ICS) solar photons into -rays, producing a diffuse and extend…
Spontaneous Baryogenesis and Primordial Black Hole Dark Matter from Ultra-Slow-Roll Inflation
Shyam Balaji
We propose a unified framework where the totality of dark matter (DM), the baryon asymmetry of the universe, and a detectable stochastic gravitational wave (GW) background originat…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
An Excited Dark Matter Solution to the MeV Galactic Center Excesses
Shyam Balaji, Damon Cleaver, Pedro De la Torre Luque
Recent COMPTEL data analysis reveals a 2 MeV continuum excess whose spatial distribution closely matches the long-standing 511 keV line observed by INTEGRAL/SPI, indicating…
