Constraining light sterile neutrino mass with the BICEP2/Keck Array 2014 B-mode polarization data

Shouvik Roy Choudhury, Sandhya Choubey

We explore the thermal light sterile neutrino situation from cosmological perspective in the $Λ CDM + r_{0.05} + N_{eff} + m_{s}^{eff}$ model usi…

Strong Bounds on Sum of Neutrino Masses in a 12 Parameter Extended Scenario with Non-Phantom Dynamical Dark Energy ( $w (z) \geq - 1$ )

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 $Λ$ CD…
