Bits missing: Finding exotic pulsars using bfloat16 on NVIDIA GPUs
Jack White, Karel Adamek, Jayanta Roy +3
The Fourier Domain Acceleration Search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy datasets. This paper quantifies the sensitivity…
A Novel Greedy Approach To Harmonic Summing Using GPUs
Karel Adamek, Jayanta Roy, Wesley Armour
Incoherent harmonic summing is a technique which is used to improve the sensitivity of Fourier domain search methods. A one dimensional harmonic sum is used in time-domain radio as…
The Polarization Convention of the uGMRT in Band 4
Barnali Das, Sanjay Kudale, Poonam Chandra +3
We present an experiment performed to understand the polarization convention adopted for band 4 (550--900 MHz) of the upgraded Giant Metrewave Radio Telescope (uGMRT). For that we…
The Expanded Giant Metrewave Radio Telescope
N. N. Patra, N. Kanekar, J. N. Chengalur +22
With 30 antennas and a maximum baseline length of 25 km, the Giant Metrewave Radio Telescope (GMRT) is the premier low-frequency radio interferometer today. We have carried out a s…
Post-correlation beamformer for time-domain studies of pulsars and transients
Jayanta Roy, Jayaram N. Chengalur, Ue-Li Pen
We present a detailed analysis of post-correlation beamforming (i.e. beamforming which involves only phased sums of the correlation of the voltages of different antennas in an arra…
Time-domain Astronomy with the GMRT: uGMRT to eGMRT
Jayanta Roy
The upgraded GMRT (uGMRT) with its unprecedented sensitivity and high figure of merit, is expected to result in the discovery of a large population of pulsars including pulsars of…
