Primordial Black Holes from Vector-Induced Curvature Perturbations Sourced by Primordial Magnetic Fields
Chang Han, Zu-Cheng Chen, Hongwei Yu +1
Generating an appreciable abundance of primordial black holes (PBHs) requires a substantial enhancement of primordial curvature perturbations on small scales. In this work, we prop…
Searching for Anisotropy in the Gravitational Wave Background Using the Parkes Pulsar Timing Array
Yiqin Chen, Shi-Yi Zhao, Zhi-Zhang Peng +17
In recent years, several pulsar timing array collaborations have reported evidence for a nanohertz gravitational wave background (GWB). Such a background signal could be produced b…
Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21
We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…
Frequency- and phase-resolved polarimetry of millisecond pulsars and its application to timing
Małgorzata Curyło, Andrew Zic, Shuangqiang Wang +16
Pulsar timing is used for a variety of applications including tests of fundamental physics, probing the structure of neutron stars, and detecting nanohertz gravitational waves. Dev…
A Multimessenger Search for the Supermassive Black Hole Binary in 3C 66B with the Parkes Pulsar Timing Array
Jacob Cardinal Tremblay, Boris Goncharov, Rutger van Haasteren +15
A subparsec supermassive black hole binary (SMBHB) at the center of the galaxy 3C 66B is a promising candidate for continuous gravitational-wave searches with pulsar timing arrays…
Searching for continuous gravitational waves in the Parkes Pulsar Timing Array Data Release 3
Shi-Yi Zhao, Zu-Cheng Chen, Jacob Cardinal Tremblay +19
We present results from an all-sky search for continuous gravitational waves from individual supermassive binary black holes using the third data release (DR3) of the Parkes Pulsar…
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…
Infrared Behavior of Induced Gravitational Waves from Isocurvature Perturbations
Chang Han, Zu-Cheng Chen, Hongwei Yu +1
Induced gravitational waves provide a powerful probe of primordial perturbations in the early universe through their distinctive spectral properties. We analyze the spectral energy…
Constraining inflation with nonminimal derivative coupling with the Parkes Pulsar Timing Array third data release
Chang Han, Li-Yang Chen, Zu-Cheng Chen +13
We study an inflation model with nonminimal derivative coupling that features a coupling between the derivative of the inflaton field and the Einstein tensor. This model naturally…
Pulsar Polarization Array Limits on Ultralight Axion-like Dark Matter
Xiao Xue, Shi Dai, Hoang Nhan Luu +20
We conduct the first-ever Pulsar Polarization Array (PPA) analysis to detect the ultralight Axion-Like Dark Matter (ALDM) using the polarization data of 22 millisecond pulsars from…
The neutron star mass, distance, and inclination from precision timing of the brilliant millisecond pulsar J04374715
Daniel J. Reardon, Matthew Bailes, Ryan M. Shannon +17
The observation of neutron stars enables the otherwise impossible study of fundamental physical processes. The timing of binary radio pulsars is particularly powerful, as it enable…
Reducing instrumental errors in Parkes Pulsar Timing Array data
Axl F. Rogers, Willem van Straten, Sergei Gulyaev +10
This paper demonstrates the impact of state-of-the-art instrumental calibration techniques on the precision of arrival times obtained from 9.6 years of observations of millisecond…
NANOGrav hints for first-order confinement-deconfinement phase transition in different QCD-matter scenarios
Zu-Cheng Chen, Shou-Long Li, Puxun Wu +1
Recent observations from several pulsar timing array (PTA) collaborations have unveiled compelling evidence for a stochastic signal in the nanohertz band. This signal aligns remark…
