Mixed Weak type inequalities for pairs of weights related to the Hardy-Littlewood maximal funcion, Calderón-Zygmund operators and their commutators
Rocío Ayala, Fabio Berra, Gladis Pradolini
We study two-weight weak-type estimates for the operator , where is the Hardy-Littlewood maximal operator or a Calderón-Zygmund operator (C…
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…
Cosmology of axion dark energy in supersymmetric models and constraints on high scale parameters
Amin Aboubrahim, Andrew H. Giman, Pran Nath
An analysis is given of interacting dark energy and dark matter where the dark energy is assumed to be an ultralight axionic field with a pseudo-Nambu-Goldstone Boson potential whi…
Gauge-independent Gravitational Waves from Cogenesis in a Conserving Universe
Wan-Zhe Feng, Jinzheng Li, Pran Nath +1
An analysis of baryogenesis and stochastic gravitational wave production is presented for an extension of the standard model where the dark sector consists of dark matter particles…
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 an…
