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…

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…

Impact of magnetic field on the gas mass fraction of galaxy clusters
Sandhya Jagannathan, Sunil Malik, Deepak Jain +1
Magnetic fields have been observed in galaxy clusters with strengths of the order of G. The non-thermal pressure exerted by magnetic fields also contributes to the total pr…
