Discovering Millisecond Pulsars in Globular Clusters with the GMRT (GCGPS)
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
The Globular Clusters GMRT Pulsar Search (GCGPS) project, launched in mid-May 2023, has emerged as one of the most successful pulsar surveys conducted with the upgraded Giant Metre…
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…
Globular Clusters GMRT Pulsar Search (GCGPS) II: Discovery of five MSPs in M69 and M70
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
This paper reports recent discoveries from the Globular Clusters GMRT Pulsar Search (GCGPS) survey, which aims to uncover pulsars in the globular clusters (GCs) of the Milky Way us…
Globular Clusters GMRT Pulsar Search (GCGPS) I: Survey description, discovery and timing of the first pulsar in NGC 6093 (M80)
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
This paper describes the new Globular Clusters GMRT Pulsar Search (GCGPS) survey. This survey aims to find MSPs in the globular clusters (GCs) of the Milky Way using uGMRT. The obs…
In-field phasing at the upgraded GMRT
Sanjay Kudale, Jayanta Roy, Jayaram N. Chengalur +2
In time-domain radio astronomy with arrays, voltages from individual antennas are added together with proper delay and fringe correction to form the beam in real-time. In order to…
Low-frequency, wideband study of an active repeater, FRB 20240114A, with the GMRT
Ujjwal Panda, Jayanta Roy, Siddhartha Bhattacharyya +2
We report the detection of 167 bursts from an active repeater, FRB 20240114A, using the uGMRT. The observations were carried over a frequency range of 300 750 MHz, and on 4 dif…
