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…
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…
Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
F. Iraci, A. Chalumeau, C. Tiburzi +46
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…
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…
On the evidence of a dark matter density spike around the primary black hole in OJ 287
Debabrata Deb, Achamveedu Gopakumar, Mauri J. Valtonen
The central engine of blazar OJ~287 is arguably the most notable supermassive black hole (SMBH) binary candidate that emits nano-Hertz (nHz) gravitational waves. This inference is…
Rapid Construction of Joint Pulsar Timing Array Datasets: The Lite Method
Bjorn Larsen, Chiara M. F. Mingarelli, Paul T. Baker +41
The International Pulsar Timing Array (IPTA)'s second data release (IPTA DR2) combines decades of observations of 65 millisecond pulsars from 7 radio telescopes. IPTA datasets shou…
Exploring the Impact of Extra Dimensions on Neutron Star Structure and Equation of State
Debabrata Deb, Manjari Bagchi, Sarmistha Banik
In this work, we explore the impact of higher dimensional spacetime on the stellar structure and thermodynamic properties of neutron stars. Utilizing the density-dependent relativi…
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…
Comparing recent PTA results on the nanohertz stochastic gravitational wave background
The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…
