Evidence of dark energy in different cosmological observations
Arindam Mazumdar, Subhendra Mohanty, Priyank Parashari
The idea of a negative-pressure dark energy component in the Universe which causes an accelerated expansion in the late Universe has deep implications in models of field theory and…
Implications of the NANOGrav result on primordial gravitational waves in nonstandard cosmologies
Sukannya Bhattacharya, Subhendra Mohanty, Priyank Parashari
Recently, the NANOGrav collaboration has reported evidence for a common-spectrum stochastic process, which might be interpreted as the first ever detection of stochastic gravitatio…
Primordial black holes and gravitational waves in nonstandard cosmologies
Sukannya Bhattacharya, Subhendra Mohanty, Priyank Parashari
For primordial black holes (PBHs) to form a considerable fraction of cold dark matter, the required amplitude of primordial scalar perturbations is quite large ($P_ζ(k) \sim 10^{-2…
Inflation models in the light of self-interacting sterile neutrinos
Arindam Mazumdar, Subhendra Mohanty, Priyank Parashari
Short baseline neutrino experiments, like LSND and MiniBooNE experiments, pointed towards the existence of eV mass scale sterile neutrinos. To reconcile sterile neutrinos with cosm…
Testing Dark energy models in the light of tension
Gaetano Lambiase, Subhendra Mohanty, Ashish Narang +1
It has been pointed out that there exists a tension in measurement between CMB and LSS observation. In this paper we show that observations can be used to test…
