Constraints on electromagnetic form factors of sub-GeV dark matter from the Cosmic Microwave Background anisotropy
Gaetano Lambiase, Subhendra Mohanty, Akhilesh Nautiyal +1
We consider dark matter which have non-zero electromagnetic form factors like electric/magnetic dipole moments and anapole moment for fermionic dark matter and Rayleigh form factor…
Hydrogen spin oscillations in a background of axions and the 21-cm brightness temperature
G. Lambiase, S. Mohanty
The 21-cm line signal arising from the hyperfine interaction in hydrogen has an important role in cosmology and provides a unique method for probing of the universe prior to the st…
Resurrecting Quartic and Quadratic inflaton potentials in two-field inflationary model
Suratna Das, Girish Kumar Chakravarty, Gaetano Lambiase +1
After the release of the PLANCK data, it is evident that inflationary paradigm has stood the test of time. Even though, it is difficult to realise inflationary paradigm in a partic…
Testing theories of Gravity and Supergravity with inflation and observations of the cosmic microwave background
Girish Kumar Chakravarty, Gaetano Lambiase, Subhendra Mohanty
Many extensions of Einstein's theory of gravity have been studied and proposed with various motivations like the quest for a quantum theory of gravity to extensions of anomalies in…
Plateau Inflation in -parity Violating MSSM
Girish Kumar Chakravarty, Ujjal Kumar Dey, Gaetano Lambiase +1
Inflation with plateau potentials give the best fit to the CMB observables as they predict tensor to scalar ratio stringently bounded by the observations from Planck and BICEP2/Kec…
Plateau Inflation in SUGRA-MSSM
Girish Kumar Chakravarty, Gaveshna Gupta, Gaetano Lambiase +1
We explored a Higgs inflationary scenario in the SUGRA embedding of the MSSM in Einstein frame where the inflaton is contained in the Higgs doublet. We include all higher o…
