Radio Continuum Emission from Evolving Star-Forming Galaxies -- I. Correlations Involving the Total Synchrotron Luminosity
Sukanta Ghosh, Luke Chamandy, Charles Jose +3
Synchrotron radiation dominates the continuum emission of star-forming galaxies in the frequency range from a few to about . We model the total synchrotron…
The Distribution of Cosmic Ray Electrons in Star-Forming Galaxies
Anvar Shukurov, Charles Jose
We derive explicit, algebraic expressions for the steady-state number density of cosmic ray electrons as a function of position and energy using Green's function of the diffusion e…
Turbulent dynamos in a collapsing cloud
Muhammed Irshad P, Pallavi Bhat, Kandaswamy Subramanian +1
The amplification of magnetic fields is crucial for understanding the observed magnetization of stars and galaxies. Turbulent dynamo is the primary mechanism responsible for that b…
The fine structure of the mean magnetic field in M31
Indrajit Paul, R. Vasanth Kashyap, Tuhin Ghosh +4
To explore the spatial variations of the regular (mean) magnetic field of the Andromeda galaxy (M31), we use Fourier analysis in azimuthal angle along four rings in the galaxy's pl…
Mathematical Aspects of Geophysical and Astrophysical Fluid Dynamics: Magnetic buoyancy instability in galaxies
Yasin Qazi, Anvar Shukurov, Devika Tharakkal +1
We study the nonlinear evolution of the magnetic buoyancy instability in rotating and non-rotating gas layers using numerical solutions of non-ideal, isothermal MHD equations. The…
Non-linear magnetic buoyancy instability and galactic dynamos
Yasin Qazi, Anvar. Shukurov, Frederick. A. Gent +2
Magnetic buoyancy (MBI) and Parker instabilities are strong, generic instabilities expected to occur in most astrophysical systems with sufficiently strong magnetic fields. In gala…
