The auto and cross angular power spectrum of the Cas A supernova remnant in radio and X-ray
Preetha Saha, Somnath Bharadwaj, Susmita Chakravorty +4
The shell type supernova remnant (SNR) Cas A exhibits structures at nearly all angular scales. Previous studies show the angular power spectrum of the radio emission t…
Angular power spectrum of supernova remnants: effects of structure, geometry and diffuse foreground
Samir Choudhuri, Preetha Saha, Nirupam Roy +2
The study of the intensity fluctuation power spectrum of individual supernova remnants (SNRs) can reveal the structures present at sub-pc scales, and also constrain the physical pr…
A study of Kepler supernova remnant: angular power spectrum estimation from radio frequency data
Preetha Saha, Somnath Bharadwaj, Nirupam Roy +2
Supernova remnants (SNRs) have a variety of overall morphology as well as rich structures over a wide range of scales. Quantitative study of these structures can potentially reveal…
On estimating the atomic hydrogen column density from the H I 21 cm emission spectra
Preetha Saha, Nirupam Roy, Mukul Bhattacharya
The 21 cm hyperfine transition of the atomic hydrogen (HI) in ground state is a powerful probe of the neutral gas content of the universe. This radio frequency transition has been…
