Estimating brightness temperature fluctuations using the 150-MHz TGSS survey. Monthly Notices of the Royal Astronomical Society, 494(2), 1936–19451365-2966https://doi.org/10.1093/mnras/staa762http://hdl.handle.net/10566/5882Measurements of the Galactic synchrotron emission are important for the 21-cm studies of the epoch of reionization. The study of synchrotron emission is also useful for quantifying the fluctuations in the magnetic field and the cosmic-ray electron density of the turbulent interstellar medium (ISM) of our Galaxy. Here, we present the all-sky angular power spectrum (Cℓ) measurements of the diffuse synchrotron emission obtained using the TIFR GMRT Sky Survey (TGSS) at 150 MHz.enMethods: data analysisMethods: statisticalTechniques: interferometricDark agesRadio continuum: generalBook
