Study of pulse jitter characteristics of PSR J1744-1134: Towards high precision pulsar timing with InPTA
Jibin Jose, Manoneeta Chakraborty, Neelam Dhanda Batra +15
Variations in the shapes of individual pulses introduce a broadband noise component in pulsar times of arrival beyond what is expected from radiometer noise, referred to as the jit…
Profile Reconstruction from Temporally Stable Emission Components for Timing PSR J1713+0747
Shaswata Chowdhury, M. A. Krishnakumar, Sharika Dhakappa +26
The assumption of long-term pulse-profile stability underpins high-precision pulsar timing and forms the basis of pulsar timing array experiments. However, several millisecond puls…
The Indian Pulsar Timing Array Data Release 2: III. Search for a Stochastic Gravitational Wave Background
Hemanga Tahbildar, Kunjal Vara, Mayuresh Surnis +28
We present the first independent search for an isotropic stochastic gravitational wave background in the second data release of the Indian Pulsar Timing Array, comprising of 27 mil…
Low-Frequency VLBI Network Using SKA-LOW
Hideyuki Kobayashi, Tomoaki Oyama, Kazuma Fujita +17
We propose the development of a low-frequency Very Long Baseline Interferometry (VLBI) network operating in the 100-350 MHz range, incorporating the Square Kilometre Array Low (SKA…
The SKAO Pulsar Timing Array
Ryan M. Shannon, N. D. Ramesh Bhat, Aurélien Chalumeau +22
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…
VLBI-Enabled Localization of Continuous GW Sources
Keitaro Takahashi, Takuya Akahori, Kenta Fujisawa +8
Pulsar timing arrays (PTAs) are opening the nanohertz gravitational-wave (GW) band by timing millisecond pulsars (MSPs) to target signals from supermassive black hole binaries (SMB…
Rotational Doppler Cartography of Technosignatures on Unresolved Planets
Keitaro Takahashi
The discovery of many Earth-like planets has renewed interest in whether life and technological civilizations exist elsewhere. The Search for Extraterrestrial Intelligence (SETI) s…
The SKAO Pulsar Timing Array
Ryan M. Shannon, N. D. Ramesh Bhat, Aurelien Chalumeau +23
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…
The Indian Pulsar Timing Array Data Release 2: II. Customised Single-Pulsar Noise Analysis and Noise Budget
K. Nobleson, Churchil Dwivedi, Shantanu Desai +33
We present the results of customised single-pulsar noise analysis of 27 millisecond pulsars from the second data release of the Indian Pulsar Timing Array (InPTA-DR2). We model var…
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…
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…
Realistic assessment of a single gravitational wave source localization taking into account precise pulsar distances with pulsar timing arrays
Ryo Kato, Keitaro Takahashi
Pulsar timing arrays (PTAs) are anticipated to detect continuous gravitational waves (GWs) from individual supermassive black hole binaries (SMBHBs) in the near future. To identify…
Low-frequency pulse-jitter measurement with the uGMRT I : PSR J04374715
Tomonosuke Kikunaga, Shinnosuke Hisano, Neelam Dhanda Batra +22
High-precision pulsar timing observations are limited in their accuracy by the jitter noise that appears in the arrival time of pulses. Therefore, it is important to systematically…
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…
