Reciprocating Magnetic Fields in the Pulsar Wind Observed from the Black Widow Pulsar J1720-0534
Chen-Chen Miao, Victoria Blackmon, Wei-Wei Zhu +41
We report the radio observations of the eclipsing black widow pulsar J1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 M. We obtain t…
Ultra-wide Bandwidth Observations of 19 pulsars with Parkes telescope
Z. R. Zhou, J. B. Wang, N. Wang +2
Flux densities are basic observation parameters to describe pulsars. In the most updated pulsar catalog, 24% of the listed radio pulsars have no flux density measurement at any fre…
High-precision search for dark photon dark matter with the Parkes Pulsar Timing Array
Xiao Xue, Zi-Qing Xia, Xingjiang Zhu +20
The nature of dark matter remains obscure in spite of decades of experimental efforts. The mass of dark matter candidates can span a wide range, and its coupling with the Standard…
Constraining cosmological phase transitions with the Parkes Pulsar Timing Array
Xiao Xue, Ligong Bian, Jing Shu +15
A cosmological first-order phase transition is expected to produce a stochastic gravitational wave background. If the phase transition temperature is on the MeV scale, the power sp…
Wideband Monitoring Observations of PSR J1803-3002A in the Globular Cluster NGC 6522
Lei Zhang, Richard N. Manchester, Andrew D. Cameron +10
We report the first wideband monitoring observations of PSR J1803-3002A, a relatively bright millisecond pulsar in the globular cluster NGC 6522 with a spin period of 7.1 ms and no…
The two emission states of PSR B1534+12
S. Q. Wang, G. Hobbs, J. B. Wang +10
We have observed PSR~B1534+12 (J1537+1155), a pulsar with a neutron star companion, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We found that this pulsa…
Precision orbital dynamics from interstellar scintillation arcs for PSR J0437-4715
Daniel J. Reardon, William A. Coles, Matthew Bailes +17
Intensity scintillations of radio pulsars are known to originate from interference between waves scattered by the electron density irregularities of interstellar plasma, often lead…
Radio observations of two intermittent pulsars: PSRs J1832+0029 and J1841-0500
S. Q. Wang, J. B. Wang, G. Hobbs +8
We present long-term observations of two intermittent pulsars, PSRs~J1832+0029 and J18410500 using the Parkes 64\,m radio telescope. The radio emission for these pulsars switche…
The Parkes Pulsar Timing Array Project: Second data release
M. Kerr, D. J. Reardon, G. Hobbs +27
We describe 14 years of public data from the Parkes Pulsar Timing Array (PPTA), an ongoing project that is producing precise measurements of pulse times of arrival from 26 millisec…
Probing the emission states of PSR J1107-5907
Jingbo Wang, George Hobbs, Matthew Kerr +14
The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very…
Wide Bandwidth Observations of Pulsars C, D and J in 47 Tucanae
Lei Zhang, George Hobbs, Richard N. Manchester +13
We report the first wideband observations of pulsars C, D and J in the globular cluster 47Tucanae (NGC 104) using the Ultra-Wideband Low (UWL) receiver system recently installed on…
Flux density measurements for 32 pulsars in the 20 cm band
Yan-Wei Xie, Jing-Bo Wang, George Hobbs +11
Flux density measurements provide fundamental observational parameters that describe a pulsar. In the current pulsar catalogue, 27% of radio pulsars have no flux density measuremen…
Parkes Pulsar Timing Array constraints on ultralight scalar-field dark matter
Nataliya K. Porayko, Xingjiang Zhu, Yuri Levin +27
It is widely accepted that dark matter contributes about a quarter of the critical mass-energy density in our Universe. The nature of dark matter is currently unknown, with the mas…
Correcting for the solar wind in pulsar timing observations: the role of simultaneous a nd l ow-frequency observations
Ze-xi Niu, George Hobbs, Jing-bo Wang +1
The primary goal of the pulsar timing array projects is to detect ultra-low-frequency gravitational waves. The pulsar data sets are affected by numerous noise processes including v…
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…
Gravitational waves from binary supermassive black holes missing in pulsar observations
R. M. Shannon, V. Ravi, L. T. Lentati +19
Gravitational waves are expected to be radiated by supermassive black hole binaries formed during galaxy mergers. A stochastic superposition of gravitational waves from all such bi…
Detection and localization of single-source gravitational waves with pulsar timing arrays
Xing-Jiang Zhu, Linqing Wen, George Hobbs +7
Pulsar timing arrays (PTAs) can be used to search for very low frequency (-- Hz) gravitational waves (GWs). In this paper we present a general method for the dete…
