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…

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…

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…

Upper limits on dark energy-dark matter interaction from DESI DR2 in a field-theoretic analysis

Amin Aboubrahim, Pran Nath

One of the important issues both in particle physics and cosmology relates to whether dark energy is a cosmological constant , or is dynamical in nature such as quintessence. I…

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.…

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 meas…
