<div class=""><span style="font-size: 14px;" class="">On Friday February 26 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 Sheng Yang from the Stockholm University.</span></div>

<div class=""><span style="font-size: 14px;" class="">Title: Electromagnetic signals from gravitational wave events</span></div>
<div class=""><span style="font-size: 14px;" class=""><br class="">
</span></div>
<div class=""><span style="font-size: 14px;" class="">Abstract: Gravitational-wave (GW) signal were finally detected by LIGO on 14th September 2015. On 17th August 2017, the joint observations of a compact binary coalescence in both GW and electromagnetic (EM)
channels mark the beginning of the GW multi-messenger astronomy era. In this talk, I will briefly present the followup searches of possible optical counterparts of GW events. I have developed the observational strategies for trigger search, developed pipelines
for image analysis and automatic candidate vetting via machine learning algorithm, as well as contribution to spectroscopic identifications and further inferences. I will show our main contributions (on behalf of GRAWITA and DLT40 projects which I was part
of) during the first three LIGO-VIRGO collaboration runs. In particular, we had an independent discovery of the kilonova AT 2017gfo, that is, the optical counterpart of GW 170817/GRB 170817A. Finally, as a postdoc at OKC Stockholm now, I will present my current
work within the ZTF survey, the GREAT environment, and our plans for search of future GW counterparts.</span></div>
