The Life and Science of Thanu Padmanabhan
Jasjeet Singh Bagla, Krishnakanta Bhattacharya, Sumanta Chakraborty +21
Thanu Padmanabhan was a renowned Indian theoretical physicist known for his research in general relativity, cosmology, and quantum gravity. In an extraordinary career spanning fort…
Imprints of the post recombination dissipation of helical magnetic field on the Cosmic Microwave Background Radiation
Sandhya Jagannathan, Ramkishor Sharma, T. R. Seshadri
Astrophysical magnetic fields decay primarily via two processes namely, ambipolar diffusion and turbulence. Constraints on the strength and the spectral index of non-helical magnet…
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…
Scalar spectral index in the presence of Primordial Black Holes
Gaveshna Gupta, Ramkishor Sharma, T. R. Seshadri
We study the possibility of reheating the universe in its early stages through the evaporation of Primordial Black Holes (PBHs) that are formed due to the collapse of the inhomogen…
The generation of helical magnetic field in a viable scenario of Inflationary Magnetogenesis
Ramkishor Sharma, Kandaswamy Subramanian, T. R. Seshadri
We study the generation of helical magnetic fields in a model of inflationary magnetogenesis which is free from the strong coupling and back-reaction problems. To generate helical…
Role of intervening Mg II absorbers on the rotation measure and fractional polarisation of the background quasars
Sunil Malik, Hum Chand, T. R. Seshadri
We probed the magnetic fields in high-redshift galaxies using excess extragalactic contribution to residual rotation measure (RRM) for quasar sightlines with intervening Mg II abso…
