ELAIS-N1 deep field uGMRT Band-2: constraints on diffuse Galactic synchrotron emission power spectrum

Rashmi Sagar, Abhirup Datta, Arnab Chakraborty +13

We present high sensitivity, low radio frequency continuum observations of the ELAIS-N1 field with 32 hours of observations of the uGMRT Band-2 ( MHz) covering $5.86\,\tex…

Mitigating gain calibration errors from EoR observations with SKA1-Low AA*

Eeshan Beohar, Abhirup Datta, Anshuman Tripathi +2

The observations of the redshifted 21-cm signal from neutral hydrogen are a promising probe for understanding the Cosmic Dawn and the Epoch of Reionisation (EoR). One of the primar…
