Bounds on sterile neutrino lifetime and mixing angle with active neutrinos by global 21 cm signal
Pravin Kumar Natwariya, Alekha C. Nayak
Sterile neutrinos can be a possible candidate for dark matter. Sterile neutrinos are radiatively unstable and can inject photon energy into the intergalactic medium (IGM). The inje…
EDGES signal in presence of magnetic fields
Pravin Kumar Natwariya, Jitesh R. Bhatt
We study the 21-cm differential brightness temperature in the presence of primordial helical magnetic fields for redshift . We argue that the -effect that sets in at ea…
Magnetic fields in a hot dense neutrino plasma and the Gravitational Waves
Arun Kumar Pandey, Pravin Kumar Natwariya, Jitesh R Bhatt
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…
Viscosity in cosmic fluids
Pravin Kumar Natwariya, Jitesh R Bhatt, Arun Kumar Pandey
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 vi…
Baryon-Dark matter interaction in presence of magnetic fields in light of EDGES signal
Jitesh R. Bhatt, Pravin Kumar Natwariya, Alekha C. Nayak +1
We have shown that in presence of a cosmic magnetic field the bounds on baryon dark matter cross-section (), dark-matter mass () and values of the magnetic field ($B_0…
