Massive stars exploding in a He-rich circumstellar medium X. Flash spectral features in the Type Ibn SN 2019cj and observations of SN 2018jmt
Z. -Y. Wang, A. Pastorello, K. Maeda +48
We present optical and near-infrared observations of two Type Ibn supernovae (SNe), SN 2018jmt and SN 2019cj. Their light curves have rise times of about 10 days, reaching an absol…
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…
Evaluating the prevalence of spurious correlations in pulsar timing array datasets
Andrew Zic, George Hobbs, R. M. Shannon +13
Pulsar timing array collaborations have recently reported evidence for a noise process with a common spectrum among the millisecond pulsars in the arrays. The spectral properties o…
On the evidence for a common-spectrum process in the search for the nanohertz gravitational-wave background with the Parkes Pulsar Timing Array
Boris Goncharov, R. M. Shannon, D. J. Reardon +26
A nanohertz-frequency stochastic gravitational-wave background can potentially be detected through the precise timing of an array of millisecond pulsars. This background produces l…
The Parkes pulsar timing array second data release: Timing analysis
D. J. Reardon, R. M. Shannon, A. D. Cameron +14
The main goal of pulsar timing array experiments is to detect correlated signals such as nanohertz-frequency gravitational waves. Pulsar timing data collected in dense monitoring c…
Comparison of Pulsar Positions from Timing and Very Long Baseline Astrometry
J. B. Wang, W. A. Coles, G. Hobbs +22
Pulsar positions can be measured with high precision using both pulsar timing methods and very-long-baseline interferometry (VLBI). Pulsar timing positions are referenced to a sola…
The disturbance of a millisecond pulsar magnetosphere
R. M. Shannon, L. T. Lentati, M. Kerr +21
Pulsar timing has enabled some of the strongest tests of fundamental physics. Central to the technique is the assumption that the detected radio pulses can be used to accurately me…
Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays
D. R. Madison, X. -J. Zhu, G. Hobbs +23
By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…
Timing analysis for 20 millisecond pulsars in the Parkes Pulsar Timing Array
D. J. Reardon, G. Hobbs, W. Coles +18
We present timing models for 20 millisecond pulsars in the Parkes Pulsar Timing Array. The precision of the parameter measurements in these models has been improved over earlier re…
Pulsar Observations of Extreme Scattering Events
W. A. Coles, M. Kerr, R. M. Shannon +17
Extreme scattering events (ESEs) in the interstellar medium (ISM) were first observed in regular flux measurements of compact extragalactic sources. They are characterized by a flu…
An all-sky search for continuous gravitational waves in the Parkes Pulsar Timing Array data set
X. -J. Zhu, G. Hobbs, L. Wen +16
We present results of an all-sky search in the Parkes Pulsar Timing Array (PPTA) Data Release 1 data set for continuous gravitational waves (GWs) in the frequency range from $5\tim…
Limitations in timing precision due to single-pulse shape variability in millisecond pulsars
R. M. Shannon, S. Osłowski, S. Dai +17
High-sensitivity radio-frequency observations of millisecond pulsars usually show stochastic, broadband, pulse-shape variations intrinsic to the pulsar emission process. These vari…
