Discovery of an Unbound Flyby Companion of UBC 63: In the Immediate Aftermath of a Close Encounter

Samrat Biswas, Biman J Medhi, Sergio Messina +8

We re-investigate the open cluster UBC 63 using the Gaia DR3 data and show that, rather than being a single cluster as previously classified, it is a compelling candidate for a dou…

Inflationary models in a minimally coupled $f (R, T)$ gravity: Constraints from $P l an c k$ , BICEP/ $K ec k$ , and ACT

Biswajit Deb, Atri Deshamukhya

The advent of high-precision cosmological observations has challenged many traditional inflationary models. Data from $P l an c k$ 2018 along with the BICEP/ $K ec k$ 2018 result have alr…
