Louis Bondonneau’s NenuFAR pulsar catalogue paper has recently been published in A&A!

If you are interested in which (Northern Hemisphere) pulsars are detected and what their pulse profiles look like at the very lowest radio frequencies observable from Earth (10-85 MHz), have a look.

I just submitted SUSPECT Paper II for publication this afternoon. The paper deals with profile evolution and frequency-dependent single-pulse modulation, in particular at low frequencies.

Let’s hope for a quick review and publication. Fingers crossed!

Some of the SKAO Science Book Chapters (“Advancing Astrophysics with the SKA II”) have appeared on the arXiv recently, with an overview given at the link below.

SKAO Science Book Overview

Unfortunately, the links in that document do not currently work, and you have to search for the publications manually …

Last week I attended the Pulsar and Neutron Star Entretiens 2026 meeting in Paris, which is an informal gathering of mostly French-affiliated pulsar and neutron star experts, similar to the Orange Pulsar Meeting in Australia or the SPINS-UK meeting in the UK. I much enjoyed the more interactive format …

I attended the Paris SKA conference at Paris Observatory - PSL in Meudon this week. I gave a poster presentation titled “Pulsar Radio Phenomenology and Fundamental Physics”, which summarised the key pulsar observables and some of our recent work on an approachable level, targeted at non-experts.

Here is the abstract:

In …

After an earlier wave of Zenodo submissions in February, I published my slides on absolute flux density calibrating beam-formed pulsar data from the NenuFAR beam model & polarisation meeting 2025 on Zenodo.

Here is the DOI link:

Absolute Flux Density Calibration of Pulsar Data, Paris Meudon, France

I just published some supplementary data for SUSPECT Paper I on Zenodo.

This includes the integrated pulse profile of PSR B1822-09 at 650 MHz obtained from our uGMRT observations on 2023-04-23, as well as the entire dataset (8723 files) of single pulse dynamic spectrum plots in PDF format. This amounts …

In April 2025, I gave an invited review talk about FRBs called “Fast Radio Bursts: An observational perspective” at the Les Houches workshop in the French Alps, near Chamonix. This was done as part of the Feeling the pull and the pulse of relativistic magnetospheres conference, which brought together world …

This week, I published some of my recent conference slides and posters on the Zenodo website. This is beneficial because it makes them more widely available and because Zenodo assigns a static DOI to each upload. It is easy to cite and reference my conference publications this way, for instance …

Our paper on FRB optical constraints was accepted for publication in the journal MNRAS!

Our SUSPECT project overview paper (paper I) was accepted for publication in the journal Astronomy & Astrophysics (A&A)!

Please find the abstract and selected plots from the paper below.

Context. Radio pulsars exhibit a plethora of complex phenomena at the single-pulse level. However, the intricacies of their radio emission remain …

Our paper on FRB multiwavelength constraints was accepted for publication!

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 …

The MeerTRAP team recently discovered the first repeating fast radio burst (FRB), FRB 20240619D, with the MeerKAT telescope. Despite the MeerKAT discoveries of dozens of apparently one-off FRBs, canonical radio pulsars, and long-period radio sources, this is the first discovery of a clearly repeating FRB source with MeerKAT.

Here is …

My MeerKAT FRB paper was accepted for publication!

Please find the abstract and selected plots from the paper below.

We present a sample of well-localised Fast Radio Bursts (FRBs) discovered by the MeerTRAP project at the MeerKAT telescope in South Africa. We discovered the three FRBs in single coherent tied-array …

We had a bit of a “paper splash” today with 4 new MeerTRAP FRB papers posted on the arXiv this morning. I just wanted to quickly share the excitement with you, as it is quite a rare opportunity, at least for such a significant release.

Please find the links to …

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 …

Our paper led by Dr Kaustubh Rajwade on the first three Fast Radio Bursts (FRBs) reported by MeerTRAP was published in the journal Monthly Notices of the Royal Astronomical Society. We report on their discoveries, localisations, scattering and scintillation properties and identify a potential host galaxy for one of them …

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 …

Our paper led by PhD student Tiaan Bezuidenhout on the first twelve Galactic sources discovered with the MeerTRAP single-pulse search instrument at the MeerKAT telescope in South Africa was accepted for publication in the journal Monthly Notices of the Royal Astronomical Society. It reports on twelve discoveries of what might …
