The Effect of on Visibility Correlation and Power Spectrum Estimation
Prasun Dutta, Tapomoy Guha Sarkar, S. Pratik Khastgir
Visibility-visibility correlation has been proposed as a technique for the estimation of power spectrum, and used extensively for small field of view observations, where the effect…
Probing Turbulence in the Interstellar Medium of Galaxies
Prasun Dutta, Ayesha Begum, Somnath Bharadwaj +1
The power spectrum of HI intensity fluctuation of the interstellar medium carries information of the turbulence dynamics therein. We present a method to estimate the power spectrum…
A Study of ISM of Dwarf Galaxies Using HI Power Spectrum Analysis
Prasun Dutta, Ayesha Begum, Somnath Bharadwaj +1
We estimate the power spectrum of HI intensity fluctuations for a sample of 8 galaxies (7 dwarf and one spiral). The power spectrum can be fitted to a power law P_HI(U) = A U^αfor…
