Extended Universal Rotational Curve of Spiral Galaxies
Esha Bhatia, Paolo Salucci, Tiziano Schiavone +1
In this work, we aim to advance the Universal Rotation Curve (URC) paradigm by leveraging new data and extending its observational domain. Building on previous studies that establi…
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.…
Exploring velocity dispersion anisotropy in a dark matter dominated ultra-diffuse galaxy with modified gravity models
Esha Bhatia, Sayan Chakrabarti, Sovan Chakraborty
The kinematics of the ultra-diffuse galaxy (UDG) NGC1052-DF44 is primarily influenced by the presence of dark matter (DM). In this paper, we conduct a contrasting kinematic study o…
Phenomenology of renormalization group improved gravity from the kinematics of SPARC galaxies
Esha Bhatia, Sayan Chakrabarti, Sovan Chakraborty
Renormalization Group correction to General Relativity (RGGR) proposes a logarithmic running of the gravitational coupling , resulting in a modified description of…
Velocity dispersion of dark matter deficient ultra-diffuse galaxies: A case for modified gravity
Esha Bhatia, Sayan Chakrabarti, Sovan Chakraborty
The line of sight velocity dispersion of the ultra-diffuse galaxies (UDGs) NGC1052-DF2 and NGC1052-DF4 have been reasonably explained only with the baryonic matter, without requiri…
