Updated 1.1% Precision Values of the Hubble Constant with Corrected Pantheon+ and Dark Energy Survey (DES)-DOVEKIE Type Ia Supernovae
Shouvik Roy Choudhury
We update the Hubble constant measurement with corrected Pantheon+ and DES-DOVEKIE supernovae. The use of DES-DOVEKIE here is the first application of DES-DOVEKIE to a distance-lad…
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.…
First constraints on non-minimally coupled Natural and Coleman-Weinberg inflation and massive neutrino self-interactions with Planck+BICEP/Keck
Nilay Bostan, Shouvik Roy Choudhury
In this work, for the first time in literature, we study the predictions of non-minimally coupled Natural and Coleman-Weinberg potentials in the plane, and an extended C…
A gravitational constant transition within cepheids as supernovae calibrators can solve the Hubble tension
Ruchika, Himansh Rathore, Shouvik Roy Choudhury +1
Local universe measurements of the Hubble constant (H0) using SNe Ia with Cepheids as calibrators yield a value of H0 which is in tension with the value inferred from the CMB and o…
Neutrino mass and mass ordering: No conclusive evidence for normal ordering
Stefano Gariazzo, Martina Gerbino, Thejs Brinckmann +8
The extraction of the neutrino mass ordering is one of the major challenges in particle physics and cosmology, not only for its implications for a fundamental theory of mass genera…
Neutrino Properties with Ground-Based Millimeter-Wavelength Line Intensity Mapping
Azadeh Moradinezhad Dizgah, Garrett K. Keating, Kirit S. Karkare +2
Line intensity mapping (LIM) is emerging as a powerful technique to map the cosmic large-scale structure and to probe cosmology over a wide range of redshifts and spatial scales. W…
Updated constraints on massive neutrino self-interactions from cosmology in light of the tension
Shouvik Roy Choudhury, Steen Hannestad, Thomas Tram
We have updated the constraints on flavour universal neutrino self-interactions mediated by a heavy scalar, in the effective 4-fermion interaction limit. We use the relaxation time…
Updated results on neutrino mass and mass hierarchy from cosmology with Planck 2018 likelihoods
Shouvik Roy Choudhury, Steen Hannestad
In this work we update the bounds on from latest publicly available cosmological data and likelihoods using Bayesian analysis, while explicitly considering particular ne…
Updated Bounds on Sum of Neutrino Masses in Various Cosmological Scenarios
Shouvik Roy Choudhury, Sandhya Choubey
We present strong bounds on the sum of three active neutrino masses () in various cosmological models. We use the following baseline datasets: CMB temperature data from P…
