<div><b data-stringify-type="bold"><u>When/where:</u></b><b><u> 30th of May 11:00 in FC61</u></b><br>
<b>Speaker</b>: Juri Poutanen (University of Turku, Finland)<span aria-label="" class="c-mrkdwn__br" data-stringify-type="paragraph-break"></span><br>
<b>Title</b>: Highlights from IXPE observatory<br>
<span aria-label="" class="c-mrkdwn__br" data-stringify-type="paragraph-break"></span><b>Abstract</b>: How to learn about geometry of astrophysical sources if they cannot be resolved?<br>
One of the options is to study them in polarized light. Scattering in an asymmetric medium produces polarized radiation with
<br>
the polarization degree reflecting the asymmetry and the polarization angle - the orientation of the medium.
<br>
Polarization of synchrotron radiation allows us to measure the orientation of the magnetic field and its homogeneity.<br>
<span aria-label="" class="c-mrkdwn__br" data-stringify-type="paragraph-break"></span>Compact objects such as neutron stars and black holes emit most of their radiation in the X-ray band and thus it is natural to look for polarization in that band.
<br>
The launch of the Imaging X-ray Polarimeter Explorer (IXPE) in December 2021 opened a new window to the Universe allowing us to study compact sources with polarized X-rays.<br>
In this talk, I will give an overview of the IXPE observatory and present major results concentrating mostly on X-ray pulsars and weakly magnetized neutron stars.
<br>
I will also mention discoveries made in other fields, such as magnetars, supernova remnants, and jets in blazars.</div>
