Optical Counterparts of MeerKLASS L-band and UHF-band surveys
M. Klein, S. Mangla, J. Mohr +7
Context: Wide-area radio continuum surveys require reliable optical and infrared counterpart identification, but high optical source densities and extended or multi-component radio…
Studying Ionosphere Using SKA-Low and SKA-Mid
Abhirup Datta, Samit Kumar Pal, Sarvesh Mangla +4
The Earth's ionosphere introduces systematic effects that limit the performance of radio interferometers operating at low frequencies (\,GHz). These ionospheric effects…
Fast Simultaneous Surveys with On-the-Fly Mapping
Suman Chatterjee, Sarvesh Mangla, Sourabh Paul +10
The SKAO is a next-generation radio telescope that will transform our understanding of the formation and evolution of radio galaxies, quasars, transients, and other cosmic sources.…
Tracing Large-scale Structure with the MeerKLASS On-the-Fly Survey: Angular Clustering of Radio Sources at 816 MHz
Sourabh Paul, Suman Chatterjee, Keith Grainge +8
We present the first measurement of the angular two-point correlation function \(w(θ)\) of radio sources from the MeerKAT Large Area Synoptic Survey (MeerKLASS) UHF on-the-fly (OTF…
The MeerKLASS L-band On-the-Fly Continuum Survey: Data Release 1
Sarvesh Mangla, Joseph J. Mohr, Kristof Rozgonyi +8
The MeerKAT Large Area Synoptic Survey (MeerKLASS) collaboration has acquired multiple passes of L-band (856-1712 MHz) scanning observations over a 268 deg sky region. This sca…
The MeerKLASS On-the-Fly continuum survey: pipeline design and validation
Suman Chatterjee, Mario G. Santos, Kristof Rozgonyi +8
The MeerKAT Large Area Synoptic Survey (MeerKLASS) is designed to map large areas of the Southern sky for cosmology using the single-dish HI intensity mapping (IM) technique, while…
The MeerKLASS UHF On-the-Fly Continuum Survey -- Data Release I
Sourabh Paul, Keith Grainge, Mario G. Santos +9
We present the first public data release (DR1) from the interferometric component of the MeerKAT Large Area Synoptic Survey (MeerKLASS) UHF survey, a legacy program demonstrating a…
Calibration requirement for Epoch of Reionization 21-cm signal observation -- III. Bias and variance in uGMRT ELAIS-N1 field power spectrum
Saikat Gayen, Rashmi Sagar, Sarvesh Mangla +6
Power spectrum of \HI 21-cm radiation is one of the promising probes to study large scale structure of the universe and understand galaxy formation and evolution. The presence of f…
The spectral study of the faint radio sources in the ELAIS N1 field
Akriti Sinha, Sarvesh Mangla, Abhirup Datta
Understanding the spectral properties of sources is crucial for the characterization of the radio source population. In this work, we have extensively studied the ELAIS N1 field us…
Spectral Analysis of ionospheric density variations measured with the large radio telescope in the Low-Latitude region
Sarvesh Mangla, Abhirup Datta
The low-latitude ionosphere is a dynamic region with a wide range of disturbances in temporal and spatial scales. The Giant Metrewave Radio Telescope (GMRT) situated in the low-lat…
Exploring Earth's Ionosphere and its effect on low radio frequency observation with the uGMRT and the SKA
Sarvesh Mangla, Sumanjit Chakraborty, Abhirup Datta +1
The Earth's ionosphere introduces systematic effects that limit the performance of a radio interferometer at low frequencies (\,GHz). These effects become more pronounc…
Study of the equatorial ionosphere using the Giant Metrewave Radio Telescope (GMRT) at sub-GHz frequencies
Sarvesh Mangla, Abhirup Datta
Radio interferometers, which are designed to observe astrophysical objects in the universe, can also be used to study the Earth's ionosphere. Radio interferometers like the Giant M…
