<p>Hello</p>
<p>On Friday October the 1st we will have the four astronomy
seminar of the year with Daichi Tsuna (University of Tokyo)
speaking via Zoom at 14:00. Please note the special time.</p>
<p><b>Multi-wavelength Emissions from Supernovae with
Circumstellar Interaction</b><br>
<br>
Recent transient observations find that a supernova is often
surrounded by a dense circumstellar matter (CSM), presumably
erupted by the progenitor star just before its death. The
collision of the supernova ejecta with the CSM create shocks,
which can power not only optical emission but also emissions in
other wavelengths. In this seminar I will talk about our recent
theoretical efforts to characterize the multi-wavelength view of
supernovae involving CSM interaction.<br>
</p>
<p>We are trying something new this year with leaving the Zoom
call open after the formal hour of the seminar is up to allow
the speaker, if they wish, to chat informally with anyone who is
interested.</p>
Thanks<br>
<p> Chris and Tine</p>
