Postdoc position in Theoretical Modelling of Bright and Fast Radio Transients

The goal of this project is to conduct theoretical modelling and interpretation of bright and fast radio transients, as detected by low frequency radio telescopes such as LOFAR (the LOw Frequency ARray). We are finding increasing numbers of radio transients with durations from seconds to minutes, such as the recently identified population of Long Period Radio Transients (LPTs). Our group identified the first progenitor of one of these systems, a white dwarf and M dwarf binary system, though it remains unclear if this can explain the full population of LPTs. It also remains unclear what the emission mechanisms are for these radio transients. Given their brightness and short duration, the sources producing this emission are very likely coherent and/or highly relativistic. This position aims to push forward our understanding of these mysterious sources by developing novel theoretical models of different progenitor systems, such as binary systems containing at least one compact source.

Through the QuickBlitz team, we will detect more fast and bright transients using imaging observations conducted by LOFAR2.0, a significantly upgraded LOFAR. In addition to standard LOFAR2.0 observations, the QuickBlitz team are building a new instrument for LOFAR2.0, AARTFAAC2.0, that can produce whole visible sky images every second to search for the most extreme and rarest radio transients. You will work closely with the observers in our team to model and interpret our discoveries.

Tasks and responsibilities:

• You will develop novel models of coherent radio outbursts that can be tested by observational data.
• You will use your theoretical expertise to model and interpret radio transients detected by the QuickBlitz team.
• You will conduct research, communicate results via peer-reviewed publication and at conferences.
• You will be a proactive member of the research group and have the opportunity to co-advise projects of MSc and BSc students.
• You will contribute to creating an open, safe and inclusive working environment. 

 Your profile:

• A PhD in physics, astronomy or a related field completed upon your arrival
• A committed researcher, demonstrated by previous research experience, publications and presentations at international conferences.
• Experience in theoretical modelling of coherent emission mechanisms.
• Excellent communication and writing skills in English.
• The ability to work both independently and collaboratively in a multidisciplinary environment.
