Revisiting wideband pulsar timing measurements
Abhimanyu Susobhanan, Avinash Kumar Paladi, Réka Desmecht +28
In the wideband paradigm of pulsar timing, the time of arrival of a pulsar pulse is measured simultaneously with the corresponding dispersion measure from a frequency-resolved inte…
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…
Improving DM estimates using low-frequency scattering-broadening estimates
Jaikhomba Singha, Bhal Chandra Joshi, M. A. Krishnakumar +28
A pulsar's pulse profile gets broadened at low frequencies due to dispersion along the line of sight or due to multi-path propagation. The dynamic nature of the interstellar medium…
Multi-band Extension of the Wideband Timing Technique
Avinash Kumar Paladi, Churchil Dwivedi, Prerna Rana +27
The wideband timing technique enables the high-precision simultaneous estimation of pulsar Times of Arrival (ToAs) and Dispersion Measures (DMs) while effectively modeling frequenc…
The Indian Pulsar Timing Array: First data release
Pratik Tarafdar, Nobleson K., Prerna Rana +35
We present the pulse arrival times and high-precision dispersion measure estimates for 14 millisecond pulsars observed simultaneously in the 300-500 MHz and 1260-1460 MHz frequency…
Low-frequency wideband timing of InPTA pulsars observed with the uGMRT
K Nobleson, Nikita Agarwal, Raghav Girgaonkar +29
High-precision measurements of the pulsar dispersion measure (DM) are possible using telescopes with low-frequency wideband receivers. We present an initial study of the applicatio…
MeerTRAP in the era of multi-messenger astrophysics
Kaustubh Rajwade, Benjamin Stappers, Christopher Williams +9
Real-time detections of transients and rapid multi-wavelength follow-up are at the core of modern multi-messenger astrophysics. MeerTRAP is one such instrument that has been deploy…
pinta: The uGMRT Data Processing Pipeline for the Indian Pulsar Timing Array
Abhimanyu Susobhanan, Yogesh Maan, Bhal Chandra Joshi +20
We introduce pinta, a pipeline for reducing the upgraded Giant Metre-wave Radio Telescope (uGMRT) raw pulsar timing data, developed for the Indian Pulsar Timing Array experiment. W…
Initial results from a realtime FRB search with the GBT
Devansh Agarwal, D. R. Lorimer, M. P. Surnis +11
We present the data analysis pipeline, commissioning observations and initial results from the GREENBURST fast radio burst (FRB) detection system on the Robert C. Byrd Green Bank T…
GREENBURST: a commensal fast radio burst search back-end for the Green Bank Telescope
Mayuresh P. Surnis, Devansh Agarwal, Duncan R. Lorimer +13
We describe the design and deployment of GREENBURST, a commensal Fast Radio Burst (FRB) search system at the Green Bank Telescope. GREENBURST uses the dedicated L-band receiver tap…
Verifying and Reporting Fast Radio Bursts
Griffin Foster, Aris Karastergiou, Marisa Geyer +6
Fast Radio Bursts (FRBs) are a class of short-duration transients at radio wavelengths with inferred astrophysical origin. The prototypical FRB is a broadband signal that occurs ov…
ALFABURST: A commensal search for Fast Radio Bursts with Arecibo
Griffin Foster, Aris Karastergiou, Golnoosh Golpayegani +12
ALFABURST has been searching for Fast Radio Bursts (FRBs) commensally with other projects using the Arecibo L-band Feed Array (ALFA) receiver at the Arecibo Observatory since July…
