New late-time constraints on gravity
Suresh Kumar, Rafael C. Nunes, Supriya Pan +1
Modification of general relativity (GR) inspired by theories like gravity is among the most popular ones to explain the late-time acceleration of the Universe as an alternat…
Exploring the tension and the evidence of dark sector interaction from 2D BAO measurements
Armando Bernui, Eleonora Di Valentino, William Giarè +2
We explore observational constraints on a cosmological model with an interaction between dark energy (DE) and dark matter (DM), using a compilation of 15 measurements of the 2D BAO…
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…
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…
