Prospects for GMRT to Observe Radio Waves from UHE Particles Interacting with the Moon
Sukanta Panda, Subhendra Mohanty, Padmanabhan Janardhan +1
Ultra high energy (UHE) particles of cosmic origin impact the lunar regolith and produce radio signals through Askaryan effect, signals that can be detected by Earth based radio te…
Gravitational Leptogenesis
Gaetano Lambiase, Subhendra Mohanty
We introduce a dimension five CP violating coupling between the Ricci scalar and fermions. This operator splits the energy level between neutrinos and anti-neutrinos and can genera…
Imprint of spatial curvature on inflation power spectrum
Eduard Masso, Subhendra Mohanty, Akhilesh Nautiyal +1
If the universe had a large curvature before inflation there is a deviation from the scale invariant perturbations of the inflaton at the beginning of inflation. This may have some…
Enhanced polarization of CMB from thermal gravitational waves
Kaushik Bhattacharya, Subhendra Mohanty, Akhilesh Nautiyal
If inflation was preceded by a radiation era then at the time of inflation there will exist a decoupled thermal distribution of gravitons. Gravitational waves generated during infl…
Astrophysical signals of P and T violation by gravity
A. R. Prasanna, Subhendra Mohanty
We study the observational consequences of the leading order P and T violating gauge invariant graviton-photon interactions. Such interactions give rise to gravitational birefringe…
No birefringence in Einstein's gravity
S. Mohanty, A. R. Prasanna
Einstein's theory predicts that, massive test particles with non-zero spin or angular momentum, in an external gravitation field, follow geodesics which depend upon the orientation…
