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…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Multi-qubit entanglement generation with squeezed modes
Alexandru Macridin, Andrew Cameron, Cristian Pena +3
We present a hybrid continuous variable-discrete variable entanglement generation protocol using linear optics and homodyne measurements, capable of producing multiple high-fidelit…
Discovery of Millisecond Pulsars in the Globular Cluster Omega Centauri
Shi Dai, Simon Johnston, Matthew Kerr +4
The globular cluster Omega Centauri is the most massive and luminous cluster in the Galaxy. The -ray source FL8Y J1326.74729 is coincident with the core of the cluster, lead…
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…
Serendipitous Discovery of PSR J1431-6328 as a Highly-Polarized Point Source with the Australian SKA Pathfinder
David Kaplan, Shi Dai, Emil Lenc +10
We identified a highly-polarized, steep-spectrum radio source in a deep image with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope at 888 MHz. After considering…
Search for an isotropic gravitational-wave background with the Parkes Pulsar Timing Array
Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +26
Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common t…
Experimentally bounding deviations from quantum theory for a photonic three-level system using theory-agnostic tomography
Michael Grabowecky, Christopher Pollack, Andrew Cameron +2
If one seeks to test quantum theory against many alternatives in a landscape of possible physical theories, then it is crucial to be able to analyze experimental data in a theory-a…
Entangling remote superconducting qubits via transducer-generated multi-time-bin states
Jing Wu, Changqing Wang, Andrew Cameron +1
Recent studies have shown long-distance entanglement using NV centers, atoms, and quantum dots with single-photon time-bin encoding. We propose a method to entangle remote supercon…
The First Pulsar Discovered by FAST
Lei Qian, Zhichen Pan, Di Li +20
To assist with the commissioning (Jiang et al. 2019) of the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we performed a pulsar search, with the primary goal of dev…
Entanglement swapping systems toward a quantum internet
Samantha I. Davis, Raju Valivarthi, Andrew Cameron +14
We demonstrate conditional entanglement swapping, i.e. teleportation of entanglement, between time-bin qubits at the telecommunication wavelength of 1536.4 nm with high fidelity of…
WASP-12, shrouded in mystery or just cold gas?
Simon Daley-Yates, Ricarda Beckmann, Lewis McCallum +2
Observations of the planet-hosting star WASP-12 show a distinctive depression in the \ion{Mg}{ii} and \ion{Ca}{ii} resonance lines. This has been interpreted as a marker of atmosph…
A Fast Radio Burst discovered in FAST drift scan survey
Weiwei Zhu, Di Li, Rui Luo +67
We report the discovery of a highly dispersed fast radio burst, FRB~181123, from an analysis of 1500~hr of drift-scan survey data taken using the Five-hundred-meter Aperture…
The Parkes Pulsar Timing Array Third Data Release
Andrew Zic, Daniel J. Reardon, Agastya Kapur +31
We present the third data release from the Parkes Pulsar Timing Array (PPTA) project. The release contains observations of 32 pulsars obtained using the 64-m Parkes "Murriyang" rad…
A small survey of the magnetic fields of planet-host stars
Rim Fares, Claire Moutou, Jean-François Donati +5
Using spectropolarimetry, we investigate the large-scale magnetic topologies of stars hosting close-in exoplanets. A small survey of ten stars has been done with the twin instrumen…
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…
The gravitational-wave background null hypothesis: Characterizing noise in millisecond pulsar arrival times with the Parkes Pulsar Timing Array
Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +19
The noise in millisecond pulsar (MSP) timing data can include contributions from observing instruments, the interstellar medium, the solar wind, solar system ephemeris errors, and…
