Automatic detection of fast oscillations of dark matter scalar field and updated cosmological constraints on QCDM
Amin Aboubrahim, Pran Nath
It is well known that a scalar field dark matter with a quadratic potential undergoes fast oscillations when the time period represented by the mass scale in the Klein-Gordon equat…
Natural Supercooling and Reheating along Supersymmetric Flat Directions and Observable Gravitational Waves at the Einstein Telescope and the Cosmic Explorer
Jinzheng Li, Pran Nath
We study supercooled first-order phase transitions in a supersymmetric hidden sector with a spontaneously broken , focusing on the frequency range of the Einstein Telescope…
Gravitational waves from supercooled phase transitions and pulsar timing array signals
Jinzheng Li, Pran Nath
The recent detection of a gravitational wave background in the nano-Hertz frequency range by Pulsar Timing Array (PTA) collaborations, including NANOGrav, EPTA, and PPTA, has opene…
A study of dark matter-dark energy interaction under the DESI DR2 data constraint
Amin Aboubrahim, Pran Nath
While CDM provides a good fit to cosmological data, it fails to address many of the outstanding questions in contemporary cosmology. Chief among these are the Hubble tension and…
