The prospects of measuring the angular power spectrum of the diffuse Galactic synchrotron emission with SKA1 Low
Sk. Saiyad Ali, Somnath Bharadwaj, Samir Choudhuri +2
The diffuse Galactic synchrotron emission (DGSE) is the most important diffuse foreground component for future cosmological 21-cm observations. The DGSE is also an important probe…
The visibility based Tapered Gridded Estimator (TGE) for the redshifted 21-cm power spectrum
Samir Choudhuri, Somnath Bharadwaj, Suman Chatterjee +3
We present the improved visibility based Tapered Gridded Estimator (TGE) for the power spectrum of the diffuse sky signal. The visibilities are gridded to reduce the computation, a…
Imaging the redshifted 21-cm pattern around the first sources during the cosmic dawn using the SKA
Raghunath Ghara, T. Roy Choudhury, Kanan K. Datta +1
Understanding properties of the first sources in the Universe using the redshifted \HI ~21-cm signal is one of the major aims of present and upcoming low-frequency experiments. We…
Tapering the sky response for angular power spectrum estimation from low-frequency radio-interferometric data
Samir Choudhuri, Somnath Bharadwaj, Nirupam Roy +2
It is important to correctly subtract point sources from radio-interferometric data in order to measure the power spectrum of diffuse radiation like the Galactic synchrotron or the…
