Cosmic evolution of the Faraday rotation measure in the intracluster medium of galaxy clusters
Yoan Rappaz, Jennifer Schober, Abhijit Bhausaheb Bendre +2
Radio observations have revealed magnetic fields in the intracluster medium (ICM) of galaxy clusters nearly in equipartition with turbulence. This suggests magnetic field amplifica…
On the Combined Role of Cosmic Rays and Supernova-Driven Turbulence for Galactic Dynamos
Abhijit B. Bendre, Detlef Elstner, Oliver Gressel
Large-scale coherent magnetic fields observed in the nearby galaxies are thought to originate by a mean-field dynamo. This is governed via the turbulent electromotive force (EMF, $…
Characterising the Dynamo in a Radiatively Inefficient Accretion Flow
Prasun Dhang, Abhijit Bendre, Prateek Sharma +1
We explore the MRI driven dynamo in a radiatively inefficient accretion flow (RIAF) using the mean field dynamo paradigm. Using singular value decomposition (SVD) we obtain the lea…
Turbulent transport coefficients in galactic dynamo simulations using singular value decomposition
Abhijit B. Bendre, Kandaswamy Subramanian, Detlef Elstner +1
Coherent magnetic fields in disc galaxies are thought to be generated by a large-scale (or mean-field) dynamo operating in their interstellar medium. A key driver of mean magnetic…
GMRT observations of a first sample of Extremely Inverted Spectrum Extragalactic Radio Sources (EISERS) candidates in the Northern sky
Mukul Mhaskey, Gopal-Krishna, Surajit Paul +4
We present an extension of our search for Extremely Inverted Spectrum Extragalactic Radio Sources (EISERS) to the northern celestial hemisphere. With an inverted radio spectrum of…
