FPGA-based Matched Filter Group Optimisation for SKA Pulsar Search Engine
Haomiao Wang, Ben Stappers, Prabu Thiagaraj +1
Pulsar search is one of the main tasks for the Square Kilometre Array (SKA), implemented in the central signal processor (CSP) sub-element. As most the characteristics of undiscove…
GBD-DART-II: 175 MHz Polarimetric Observation of Pulsars from Gauribidanur and a New Pulsar Signal Processing Pipeline
Arul Pandian B, Joydeep Bagchi, Prabu Thiagaraj +2
A new pulsar signal-processing pipeline has been developed for observing pulsars with the Diamond Array Radio Telescope at the Gauribidanur radio observatory. The array consists of…
GBD-DART-I : Pulsars and transient source observation between 130 MHz and 350 MHz at Gauribidanur
Arul Pandian B, Joydeep Bagchi, Prabu Thiagaraj +8
Gauribidanur Diamond Array Radio Telescope (GBD-DART) is a new small LPDA antenna array consisting of 64 short dipoles and associated receivers that has been custom developed and d…
Effects of Coronal Mass Ejection on PSR J1022+1001 and Possible Mode Change of PSR J2145-0750 in the InPTA DR2
Shaswata Chowdhury, M. A. Krishnakumar, Manjari Bagchi +27
The Indian Pulsar Timing Array (InPTA) has recently published its second data release (DR2), comprising the timing analysis of seven years of data on 27 millisecond pulsars (MSPs),…
The Indian Pulsar Timing Array Data Release 2: I. Dataset and Timing Analysis
Prerna Rana, Pratik Tarafdar, Nobleson K +44
The Indian Pulsar Timing Array (InPTA) employs unique features of the upgraded Giant Metrewave Radio Telescope (uGMRT) to monitor dozens of the International Pulsar Timing Array (I…
FPGA-based Acceleration of FT Convolution for Pulsar Search Using OpenCL
Haomiao Wang, Prabu Thiagaraj, Oliver Sinnen
The Square Kilometre Array (SKA) project will be the world largest radio telescope array. With its large number of antennas, the number of signals that need to be processed is dram…
Harmonic-summing Module of SKA on FPGA--Optimising the Irregular Memory Accesses
Haomiao Wang, Prabu Thiagaraj, Oliver Sinnen
The Square Kilometre Array (SKA), which will be the world's largest radio telescope, will enhance and boost a large number of science projects, including the search for pulsars. Th…
A GPU implementation of the Correlation Technique for Real-time Fourier Domain Pulsar Acceleration Searches
Sofia Dimoudi, Karel Adamek, Prabu Thiagaraj +3
The study of binary pulsars enables tests of general relativity. Orbital motion in binary systems causes the apparent pulsar spin frequency to drift, reducing the sensitivity of pe…
A study of fundamental limitations to statistical detection of redshifted HI from the epoch of reionization
Nithyanandan Thyagarajan, N. Udaya Shankar, Ravi Subrahmanyan +46
In this paper we explore for the first time the relative magnitudes of three fundamental sources of uncertainty, namely, foreground contamination, thermal noise and sample variance…
