An analytical method to simulate the HI 21-cm visibility signal for intensity mapping experiments
Anjan Kumar Sarkar, Somnath Bharadwaj, Visweshwar Ram Marthi
Simulations play a vital role in testing and validating HI 21-cm power spectrum estimation techniques. Conventional methods use techniques like N-body simulations to simulate the s…
Simulated foreground predictions for HI at z = 3.35 with the Ooty Wide Field Array: I. Instrument and the foregrounds
Visweshwar Ram Marthi, Suman Chatterjee, Jayaram Chengalur +1
Foreground removal is the most important step in detecting the large-scale redshifted HI 21-cm signal. Modelling foreground spectra is challenging and is further complicated by the…
Prowess - a software model for the Ooty Wide Field Array
Visweshwar Ram Marthi
One of the scientific objectives of the Ooty Wide Field Array(OWFA) is to observe the redshifted HI emission from z ~ 3.35. Although predictions spell out optimistic outcomes in re…
Simulating the z = 3.35 HI 21-cm visibility signal for the Ooty Wide Field Array(OWFA)
Suman Chatterjee, S. Bharadwaj, V. R. Marthi
The upcoming Ooty Wide Field Array (OWFA) will operate at which corresponds to the redshifted 21-cm signal from neutral hydrogen (HI) at z = 3.35. We present t…
