Relaxing cosmological tensions with a sign switching cosmological constant: Improved results with Planck, BAO, and Pantheon data
Ozgur Akarsu, Suresh Kumar, Emre Ozulker +2
We present a further observational analysis of the CDM model proposed in Akarsu et al. [Phys. Rev. D 104, 123512 (2021)]. This model is based on the recent conjecture su…
Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021
Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…
New cosmological constraints on gravity in light of full Planck-CMB and type Ia supernovae data
Suresh Kumar, Rafael C. Nunes, Priya Yadav
We investigate two new observational perspectives in the context of torsional gravitational modification of general relativity, i.e., the gravity: i) We use Pantheon data of…
Updating non-standard neutrinos properties with Planck-CMB data and full-shape analysis of BOSS and eBOSS galaxies
Suresh Kumar, Rafael C. Nunes, Priya Yadav
Using the latest observational data from Planck-CMB and its combination with the pre-reconstructed full-shape (FS) galaxy power spectrum measurements from the BOSS DR12 sample and…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
New tests of dark sector interactions from the full-shape galaxy power spectrum
Rafael C Nunes, Sunny Vagnozzi, Suresh Kumar +2
We explore the role of redshift-space galaxy clustering data in constraining non-gravitational interactions between dark energy (DE) and dark matter (DM), for which state-of-the-ar…
