Bayesian Model Comparison of versus CDM using HII galaxy Hubble diagram

Yuva Himanshu Pallam, Shantanu Desai

We complement a recent analysis comparing with CDM/CDM using HII galaxies and giant extragalactic HII regions, by carrying out Bayesian model comparison. Fo…

Fermionic versus Bosonic Dark Matter in Neutron Stars: A Bayesian Study with Multi-Density Constraints

Payaswinee Arvikar, Sakshi Gautam, Anagh Venneti +1

We perform a comparative Bayesian analysis of fermionic and bosonic dark matter admixed neutron stars (DMANS) by incorporating a comprehensive set of theoretical, experimental, and…

Redshift-space galaxy bispectrum in presence of massive neutrinos: A multipole expansion approach for Euclid

Sourav Pal, Debanjan Sarkar, Rickmoy Samanta +1

Massive neutrinos imprint distinctive signatures on the evolution of cosmic structures, notably suppressing small-scale clustering. We investigate the impact of massive neutrinos o…

Big Bang Nucleosynthesis constraints on gravity

Sai Swagat Mishra, Ameya Kolhatkar, P. K. Sahoo

Big Bang Nucleosynthesis provides us with an observational insight into the very early Universe. Since this mechanism of light element synthesis comes out of the standard model of…

Revisiting kink-like parametrization and constraints using OHD/Pantheon+/BAO samples

Simran Arora, P. K. Sahoo

We reexamine the kink-like parameterization of the deceleration parameter to derive constraints on the transition redshift from cosmic deceleration to acceleration. This is achieve…

AGN Activity and Black Hole Masses in Low Surface Brightness Galaxies

S. Ramya, T. P. Prabhu, M. Das

We present medium resolution optical spectroscopy of a sample of nine Low Surface Brightness (LSB) galaxies. For those that show clear signatures of AGN emission, we have disentang…

Detection of Extended Molecular Gas in the Disk of the LSB Galaxy Malin~2

M. Das, F. Boone, F. Viallefond

Our goal is to see if there is molecular gas extending throughout the optical low surface brightness disk of the galaxy Malin 2. We used the heterodyne receiver array (HERA) mounte…
