Exploring diffuse radio emission in galaxy clusters and groups with the uGMRT and the SKA
Surajit Paul, Ruta Kale, Abhirup Datta +13
Diffuse radio emission has been detected in a considerable number of galaxy clusters and groups, revealing the presence of pervasive cosmic magnetic fields, and of relativistic par…
Towards 21-cm Intensity Mapping at with uGMRT using the Tapered Gridded Estimator I: Foreground Avoidance
Srijita Pal, Kh. Md. Asif Elahi, Somnath Bharadwaj +8
The post-reionization neutral hydrogen (HI) 21-cm intensity mapping signal holds the potential to probe the large scale structures, study the expansion history and cons…
A study on the Clustering Properties of Radio-Selected sources in the Lockman Hole Region at 325 MHz
Aishrila Mazumder, Arnab Chakraborty, Abhirup Datta
Studying the spatial distribution of extragalactic source populations is vital in understanding the matter distribution in the Universe. It also enables understanding the cosmologi…
Observing the Reionization : Effect of Calibration and Position Errors on Realistic Observation Conditions
Aishrila Mazumder, Abhirup Datta, Arnab Chakraborty +1
Observation of the redshifted 21-cm signal from Cosmic Dawn and Epoch of Reionization is a challenging endeavor in observational cosmology. Presence of orders of magnitude brighter…
A Comparative Analysis To Deal With Missing Spectral Information Caused By RFI In Cosmological HI 21CM Observations
Arnab Chakraborty, Abhirup Datta, Aishrila Mazumder
We investigate the effect of radio-frequency interference (RFI) excision in estimating the cosmological \hi\ 21 cm power spectrum. Flagging of RFI-contaminated channels results in…
