Spectral variability in NGC 1042 ULX1
Tanuman Ghosh, Vikram Rana
We report X-ray spectral variability in an ultraluminous X-ray source NGC 1042 ULX1, using archival XMM-Newton and recent NuSTAR observations. In long-term evolution, the source ha…
Gravitational geometric phase
Banibrata Mukhopadhyay, Tanuman Ghosh, Soumya Kanti Ganguly
We show that spinors propagating in curved gravitational background acquire an interaction with spacetime curvature, which leads to a quantum mechanical geometric effect. This is s…
The Atomic Gas Mass of Green Pea Galaxies
N. Kanekar, T. Ghosh, J. Rhoads +4
We have used the Arecibo Telescope and the Green Bank Telescope to carry out a deep search for H{\sc i}~21\,cm emission from a large sample of Green Pea galaxies, yielding 19 detec…
Super-Eddington accretion onto a stellar mass ultraluminous X-ray source NGC 4190 ULX1
Tanuman Ghosh, Vikram Rana
We present the results of high-quality XMM-NEWTON observations of a ULX in the galaxy NGC 4190. The detection of spectral cutoff in NGC 4190 ULX1 spectra rules out the interpretati…
Geometric phase for Dirac Hamiltonian under gravitational fields in the non-relativistic regime
Tanuman Ghosh, Banibrata Mukhopadhyay
We show the appearance of geometric phase in a Dirac particle traversing in non-relativistic limit in a time-independent gravitational field. This turns out to be similar to the on…
