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…
