<div class=""><span style="font-size: 14px;" class="">On Friday 21st May at 10:30, we will have the next Astronomy Seminar, remotely via zoom.</span></div>

<div class=""><span style="font-size: 14px;" class="">Our speaker is Franz Kirsten from the Chalmers University of Technology. </span></div>

<div class=""><span style="font-size: 14px;" class="">Title: Towards understanding fast radio bursts -- activities at and recent results from Onsala Space Observatory</span></div>
<div class=""><span style="font-size: 14px;" class=""><br class="">
</span></div>
<div class=""><span style="font-size: 14px;" class="">Abstract: Fast radio burst are bright, millisecond-duration flashes of extragalactic origin, so far only observed at centimeter- to meter-wavelengths. The vast majority of the roughly 150 published FRBs
have only ever been seen once, roughly 20 are known to burst repeatedly, but do so in an unpredictable way. Key ingredients in understanding the source and physical origin of the emission are the environments the bursts are generated in and their spectro-polarimetric
properties. In this talk I will summarize the field and discuss the efforts that we conduct at Onsala Space Observatory. Besides running a VLBI-campaign to precisely localise FRBs, we also perform multi-telescope, multi-band observations in collaboration with
Westerbork (NL) and Torun (Poland). In 2020 we detected FRB-like bursts from a Galactic magnetar and, most recently, we precisely localised two FRBs.</span></div>
