Magnetic Fields, Star Formation Rates and Gas Densities at Sub-kpc Scales in a Pilot Sample of Nearby Galaxies
Souvik Manna, Subhashis Roy
We have estimated the magnetic field strengths of a sample of seven galaxies using their non-thermal synchrotron radio emission at metre wavelengths, and assuming energy equipartit…
The Galactic Faraday rotation sky 2020
Sebastian Hutschenreuter, Craig S. Anderson, Sarah Betti +34
This work gives an update to existing reconstructions of the Galactic Faraday rotation sky by processing almost all Faraday rotation data sets available at the end of the year 2020…
Cosmic ray flux and lockdown due to COVID19 in Kolkata -- any correlation?
A. Sen, S. Chatterjee, S. Roy +4
Cosmic ray muon flux is measured by the coincidence technique using plastic scintillation detectors in the High Energy Physics detector laboratory at Bose Institute, Kolkata. Due t…
Detection of radio emission from the gamma-ray pulsar J1732-3131 at 327 MHz
Yogesh Maan, M. A. Krishnakumar, Arun K. Naidu +4
Although originally discovered as a radio-quiet gamma-ray pulsar, J1732-3131 has exhibited intriguing detections at decameter wavelengths. We report an extensive follow-up of the p…
Probing magnetic fields with Square Kilometre array and its precursors
Subhashis Roy, Sharanya Sur, Kandaswamy Subramanian +3
Origin of magnetic fields, its structure and effects on dynamical processes in stars to galaxies are not well understood. Lack of a direct probe has hampered its study. The first p…
Synchrotron spectral index and interstellar medium densities of star-forming galaxies
Aritra Basu, Rainer Beck, Philip Schmidt +1
The spectral index of synchrotron emission is an important parameter in understanding the properties of cosmic ray electrons (CREs) and the interstellar medium (ISM). We determine…
