Impact of Intense Geomagnetic Storm on NavIC Signals Over Indore
Deepthi Ayyagari, Sumanjit Chakraborty, Abhirup Datta +1
Intense geomagnetic storms can have a strong impact on the signals (termed ionospheric scintillations) emitted by any global navigation satellite system (GNSS). The paper reports t…
An ANN Approach in Predicting Solar and Geophysical Indices from Ionospheric TEC Over Indore
Sumanjit Chakraborty, Abhirup Datta
In this paper, preliminary results from the artificial neural network (ANN) based model developed at IIT Indore has been presented. One year's hourly total electron content (TEC) d…
Study of Low-latitude Ionospheric Scintillation using NavIC
Sumanjit Chakraborty, Abhirup Datta
Equatorial ionospheric irregularities have been studied in the past and have produced interesting insights into ionospheric physics and processes. Here, we present the initial resu…
Interpreting the HI 21-cm cosmology maps through Largest Cluster Statistics -- I: Impact of the synthetic SKA1-Low observations
Saswata Dasgupta, Samit Kumar Pal, Satadru Bag +7
We analyse the evolution of the largest ionized region using the topological and morphological evolution of the redshifted 21-cm signal coming from the neutral hydrogen distributio…
Towards -cm intensity mapping at with uGMRT using the tapered gridded estimator II: Cross-polarization power spectrum
Kh. Md. Asif Elahi, Somnath Bharadwaj, Abhik Ghosh +8
Neutral hydrogen () -cm intensity mapping (IM) offers an efficient technique for mapping the large-scale structures in the universe. We introduce the 'Cross' Tapered G…
Systematic study of ionospheric scintillation over the indian low-latitudes during low solar activity conditions
Deepthi Ayyagari, Abhirup Datta, Sumanjit Chakraborty
A systematic study of ionospheric scintillation at the low-latitudes, especially around the Equatorial Ionization Anomaly (EIA) and the magnetic equator, is essential in understand…
