<p>Hi everyone,</p>
<p>I would like to inform you that the LPC2E team (Orléans, France)
is offering between one and three PhD positions, starting this
autumn, <b>for the study of pulsars and fast transients </b>(details
below). Please contact us if you are interested or circulate this
message around you.<br>
</p>
<p>Regards,</p>
<p>Gilles<br>

Thanks to the extreme stability of pulsar rotation, pulsars are considered “cosmic clocks” with a wide range of astrophysical applications. One notable example is the measurement with high evidence for Gravitational Waves via the Pulsar Timing Array (PTA) experiment recently announced in 2023. Pulsar discoveries have directly resulted in two Nobel prizes (1974 and 1993); finding more pulsars is therefore a gateway to new science. Pulsar searching has also indirectly led to the discovery of the new phenomenon of Fast Radio Bursts (FRBs), which are energetic bursts of radio waves coming from extragalactic distances. The precise nature of FRBs is still a mystery and is the driver of an active, ongoing research field.</span></p>

The $2-billion Square Kilometre Array (SKA) project is a multinational effort to build the most sensitive radio telescope ever constructed. France is a member country of the SKA and enabling the SKA is high on the national science agenda. With the SKA coming online in the near future, it is thus an exciting time to join the radio astronomy community. The LPC2E ASTRO team is involved in a range of SKA Pathfinder projects, including but not limited to NenuFAR, LOFAR, MeerKAT, Parkes, CHIME and CHORD. These instruments are already providing useful insights in the preparation for SKA. In addition, there are also huge scientific potentials we can realise with these high quality data sets, for example in searching for pulsars, FRBs, as well as PTA analyses. </span></p>

Depending on the aptitude of the candidate(s), the project could be oriented on the instrumentation and the development of signal processing algorithms, time series data processing and modeling, statistical analysis and parameter estimation using Bayesian inference, and/or the exploitation of Machine Learning (ML) based algorithms to reduce false positives caused by human generated interference signals in the observational data as opposed to genuine astrophysical signals. At the end of the PhD, we expect the student to become fully proficient in radio astronomical signal processing and an expert in time domain data analysis, particularly in the area of pulsars and fast transients. The PhD student will also take the lead on conducting a follow-up study of pulsar discoveries using the Nançay Radio Telescope (NRT) and the NenuFAR telescope at the Nançay Radio Astronomical Observatory in France. </span></p>

The team boasts the largest pulsar research group in France and is closely connected to the Nançay Radio Astronomical Observatory in the forest of Sologne. The PhD student will also have the opportunity to travel to collaborate with other partnering radio facilities mentioned above, as well as to present the research work at international conferences. A laptop will be provided, as well as access to necessary computing resources.</span><span
