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…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…

The model with a heavy Higgs spectrum consisting of and a light Higgs spectrum consisting of plet represen…
Cosmological tensions and as an alternative to CDM
Amin Aboubrahim, Pran Nath
The Standard Model of cosmology, CDM, while enormously successful, is currently unable to account for several cosmological anomalies the most prominent of which are in the measu…
Supercooled Phase Transitions: Why Thermal History of Hidden Sector Matters in Analysis of Pulsar Timing Array Signals
Jinzheng Li, Pran Nath
The detection of a gravitational wave background in the nano-Hertz frequency range from Pulsar Timing Array (PTA) observations offers new insights into evolution of the early unive…
