I maintain a software tool called scatfit, which I designed and implemented in 2022 to perform scattering fits of very low-S/N fast radio burst (FRB) data. Its primary aim is to measure the scatter broadening incurred by a radio signal (impulse) as it traverses various Galactic and extragalactic turbulent …
more ...I recently submitted the Science Using Single-Pulse Exploration with Combined Telescopes (SUSPECT) paper I to the Astronomy & Astrophysics journal and submitted it to the arXiv shortly afterwards. It gives an overview of the SUSPECT multi-telescope observing project and demonstrates several new data analysis techniques on a small subset of the …
more ...I recently uploaded our scatfit pulse profile scattering fit and simulation software to the official Python Package Index (PyPI). That means you can install it simply by typing
$ pip install scatfit
in one of your shell windows.
As scatfit includes compiled binary extensions to speed up the model evaluation (by …
We had a good representation of the Orléans/Nançay pulsar and FRB team at the 2023 Kerastari neutron star & FRB meeting in Greece. Overall, we had five talks from the group covering topics from FRBs and pulsars to SETI.
It was a truly excellent meeting! The talk quality and topic …
more ...I recently started a new academic research position at the French National Centre for Scientific Research (CNRS) and the Université d’Orléans in the beautiful city of Orléans, France. I will work on pulsars and Fast Radio Bursts as part of a more extensive multi-wavelength collaboration and with several radio …
more ...I recently published software for performing scattering fits of time domain radio signals from Fast Radio Bursts or pulsars on the Astrophysics Source Code Library (ASCL). Please find its description below.
Impulsive time domain radio signals, such as Fast Radio Bursts (FRBs) or pulsars pulses, undergo several propagation effects in …
more ...We discovered an ultra-slow spinning neutron star (~76 second period) that emits at radio frequencies with the MeerTRAP instrument at the MeerKAT telescope. The work was done in collaboration with many and led by Dr Manisha Caleb from MeerTRAP and Dr Ian Heywood from ThunderKAT. The paper was recently accepted …
more ...Back in early 2019, we observed several pulsars to better characterise their emission properties at radio frequencies and to do so systematically. Serendipitously, we caught one of the pulsars, PSR J1452-6036, about 3 hours after it had suffered a sudden spin-up event (or glitch) in its otherwise stable rotation. The …
more ...Today I gave a short public talk about my research at Jodrell Bank Observatory as part of the ‘Meet the Expert’ session. After the presentation, there were about 30 minutes of questions where people could ask me anything related to astronomy, astrophysics or physics in general (this is a somewhat …
more ...Late last year, I released the high-level observing software used for the UTMOST pulsar timing programme I paper through the Astrophysics Source Code Library. It contains monitoring and scheduling tools that we developed as part of the UTMOST project for the Molonglo Observatory Synthesis Telescope (MOST), including the fully-autonomous dynamic …
more ...Before the bustle leading up to the Christmas and New Year’s holidays, my UTMOST pulsar timing programme paper got accepted for publication in the journal Monthly Notices of the Royal Astronomical Society. The publication can be accessed online via the Astrophysics Data System. In that paper, we report updated …
more ...A collaborative paper (Meyers et al.) reporting on the spectral properties of the highly intermittent pulsar J1107-5907 at radio frequencies has recently been accepted for publication.
The publication presents the analysis of simultaneous radio observations of the pulsar with the Murchison Widefield Array (MWA) and the refurbished Molonglo Synthesis Radio …
more ...We have detected another pulsar glitch at the Molonglo Observatory Synthesis Radio Telescope in Australia, where we are observing more than 400 radio pulsars regularly, mainly with very high cadence. This one happened in the pulsar J1709-4429 and is by far the smallest one ever reported in this pulsar. The …
more ...In a recently published paper we have systematically investigated the radio spectral energy distributions of 441 radio pulsars, observed with the Parkes telescope in Australia. The publication can be accessed online via the Astrophysics Data System. This work is significant, because it considers about one fifth of the currently known …
more ...We crossed the 10,000 pulsar observations mark using the tied-array beam with the UTMOST system at the refurbished Molonglo radio telescope last night. This is a big milestone for the pulsar timing project.
Hurray!
