Reconciling large-scale Lyman- correlations with the SCRIPT Semi-numerical Model
Saptarshi Sarkar, Tirthankar Roy Choudhury
Recent analyses of high-redshift Lyman- forest observations have revealed strong correlations on scales exceeding 200 cMpc at redshift z = 6. Reproducing these large-scale corre…

Detection of giant pulses from the transitional millisecond pulsar J12274853
Saptarshi Sarkar, Jayanta Roy, Bhaswati Bhattacharyya +5
We report the discovery of giant pulse (GP) emission from the transitional millisecond pulsar (tMSP) PSR J12274853, using 174 hours of single-pulse data from the upgraded Giant…

Accelerating reionization constraints: An ANN-emulator framework for the SCRIPT Semi-numerical Model
Saptarshi Sarkar, Tirthankar Roy Choudhury
Constraining the Epoch of Reionization (EoR) with physically motivated simulations is hampered by the high cost of conventional parameter inference. We present an efficient emulato…
