    The Experiment to Detect the Global Epoch of reionization Signature (EDGES) collaboration has reported an excess absorption dip in the 21 cm signal during cosmic dawn era. The stronger than expected 21 absorption signal ...
  • Bhatt, Jitesh R.; Natwariya, Pravin Kumar; Nayak, Alekha C.; Pandey, Arun Kumar (Springer, 2020-04)
    We have shown that in presence of a cosmic magnetic field the bounds on baryon dark matter cross-section (?^), dark-matter mass (md) and values of the magnetic field (B0) can strongly influence each other. This requires ...

  • Anand, Sampurn; Bhatt, Jitesh R.; Pandey, Arun Kumar (IOP Publishing, 2017-07)
    We study the generation and evolution of magnetic field in the presence of chiral imbalance and gravitational anomaly which gives an additional contribution to the vortical current. The contribution due to gravitational ...
  • Pandey, Arun Kumar; Natwariya, Pravin Kumar; Bhatt, Jitesh R (Cornell University Library, 2019-11)
    In the present work, we have studied the spectrum of the primordial gravitational waves due to magnetic instability in the presence of neutrino asymmetry. The magnetic instability generates a helical magnetic field on a ...
  • Pandey, Arun Kumar; Natwariya, Pravin Kumar; Bhatt, Jitesh R. (American Physical Society, 2020-01)
    In the present work, we have studied the spectrum of the primordial gravitational waves due to magnetic instability in the presence of neutrino asymmetry. The magnetic instability generates a helical magnetic field on a ...
  • Pandey, Arun Kumar (Indian Institute of Technology Gandhinagar, 2017)
  • Bhatt, Jitesh R.; Pandey, Arun Kumar (Springer, 2014-12-18)
    We reexamine generation of the primordial magnetic fields, at temperature T>80 TeV, by applying a consistent kinetic theory framework which is suitably modified to take the quantum anomaly into account. The modified kinetic ...

  • Bhatt, Jitesh R.; Pandey, Arun Kumar (Cornell University Library, 2015-03)
    We apply the modified kinetic theory to study generation of magnetic field due to anomaly in a primordial plasma of the standard model particles at temperature T >80 TeV. It is known that achiral imbalance in such plasma ...
  • Bhatt, Jitesh R.; Pandey, Arun Kumar (American Physical Society, 2016-08)
    We study the generation of a magnetic field in primordial plasma of standard model particles at a temperature T>80  TeV—much higher than the electroweak scale. It is assumed that there is an excess number of right-handed ...
  • Natwariya, Pravin Kumar; Bhatt, Jitesh R.; Pandey, Arun Kumar (Springer, 2020-08)
    The effective theory of large-scale structure formation based on CDM paradigm predicts finite dissipative effects in the resulting fluid equations. In this work, we study how viscous effect that could arise if one includes ...
