Resonant Dynamics of Gravitational Wave and Chiral Alfvén wave in the Early Universe

Arun Kumar Pandey, Subalakshmi A, Sampurn Anand

In this work, we investigate the resonant interaction between stochastic gravitational waves (GWs) and chiral Alfvén waves in a magnetized chiral plasma in the early Universe. Star…

Thermal SZ effect in a magnetized IGM dominated by interacting DM decay/annihilation during dark ages

Arun Kumar Pandey, Sunil Malik

During cosmic dawn, the thermal history of the universe is well studied, and a study of this era can give us some of the most useful insight into the universe before the recombinat…

Generating Seed magnetic field à la Chiral Biermann battery

Arun Kumar Pandey, Sampurn Anand

Cosmological and astrophysical observations indicate the presence of magnetic field over all scales. In order to explain these magnetic fields, it is assumed that there exists a se…

Gravitational waves in neutrino plasma and NANOGrav signal

Arun Kumar Pandey

The recent finding of the gravitational wave (GW) signal by the NANOGrav collaboration in the nHZ frequency range has opened up the door for the existence of stochastic GWs. In the…

Implications of baryon-dark matter interaction on IGM temperature and tSZ effect with magnetic field

Arun Kumar Pandey, Sunil Malik, T. R. Seshadri

We show that the combined effect of cosmic magnetic field and a possible non-standard interaction between baryons and dark matter has interesting consequences on the thermal Sunyae…

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…

Chiral plasma instability and primordial Gravitational wave

Sampurn Anand, Jitesh R. Bhatt, Arun Kumar Pandey

It is known that cosmic magnetic field, if present, can generate anisotropic stress in the plasma and hence, can act as a source of gravitational waves. These cosmic magnetic field…
