Enhanced tensor non-Gaussianities in presence of a source
Abhishek Naskar, Supratik Pal
We address the possibility of having an enhanced signal for tensor non-Gaussianities in presence of a source, as a signature of Primordial Gravitational Waves. We employ a nearly m…

Strong Bounds on Sum of Neutrino Masses in a 12 Parameter Extended Scenario with Non-Phantom Dynamical Dark Energy ()
Shouvik Roy Choudhury, Abhishek Naskar
We obtained constraints on a 12 parameter extended cosmological scenario including non-phantom dynamical dark energy (NPDDE) with CPL parametrization. We also include the six CD…

Non-Gaussian Features of Primordial Gravitational Waves
Abhishek Naskar, Supratik Pal
We explore possible non-Gaussian features of primordial gravitational waves by constructing model-independent templates for nonlinearity parameters of tensor bispectrum. Our analys…
