The Dilaton: A Natural Resolution to the Hubble Tension via Spontaneous Scale Symmetry Breaking
Arpit Kottur, Jui Mahajan, Raka Dabhade
The statistical tension between early and late universe measurements of the Hubble constant () suggests that the dark sector is dynamical rather than static. We propose that t…
A Dynamical Scalar Field Model for Dark Energy: Addressing the Hubble Tension and Cosmic Evolution
Arpit Kottur, Jui Mahajan, Raka Dabhade
We propose a dynamical dark energy model based on a canonical scalar field with a hybrid potential of the form . We constrain the model's 11-d…
A First Order Filter for the Detection of Potentially Habitable Exoplanets
Raka Dabhade, Jebraan Mudholkar, Siddhesh Durgude +1
The search for potentially habitable exoplanets is a primary objective in modern astrophysics, yet the vast number of candidates discovered by missions like Kepler and TESS present…
Investigating the Correlation between Dark Matter Content, Ages and Mass-to-Light Ratios in Spiral Galaxies
Arpit Kottur, Meet Mehta, Raka Dabhade
We present an empirical investigation into the relationship between galactic age and dark matter content across a sample of 16 nearby, well-resolved spiral galaxies. Using raw rota…
