The Rotation Curve of the Milky Way: State of the Art, the Keplerian Decline Debate, and Implications for Dark Matter
Alessandro Melchiorri, Ruchika
For four decades, the roughly flat rotation curve (RC) of the Milky Way (MW) stood as local evidence for an extended dark matter (DM) halo. \textit{Gaia} DR3 has changed the pictur…

Observational Constraints on Axion(s) Dark Energy with a Cosmological Constant
Ruchika, Shahnawaz A. Adil, Koushik Dutta +2
The present work deals with a dark energy model that has an oscillating scalar field potential along with a cosmological constant (CC). The oscillating part of the potential repres…

Model independent constraints on dark energy evolution from low-redshift observations
Salvatore Capozziello, Ruchika, Anjan A Sen
Knowing the late time evolution of the Universe and finding out the causes for this evolution are the important challenges of modern cosmology. In this work, we adopt a model-indep…
