AoT Leiden: Galaxies in the Universe!
September 27, 2021 @ 8:00 PM - 9:30 PM CESTFree
For our next event, we will be back at Grandcafé De Burcht (Burgsteeg 14, 2312 JS Leiden) on Monday 27 September at 20:00 CEST. It’s a free event, but registration is required due to COVID-19 regulations! Please read the important information below.
There is limited space so save your seat at https://aotleiden.eventbrite.nl and join us for an evening of informal astronomy, fun games, and great beer! François Mernier and Erik Osinga will tell us about galaxies in our Universe.
François Mernier: “The link between supernovae, supermassive black holes, and the large-scale Universe”
François Mernier is a research fellow at ESTEC (Noordwijk), one of the main centres of the European Space Agency. Although he loves all sides of X-ray astronomy, his work mainly focuses on galaxy clusters. In particular, he investigates the properties of the “intracluster medium”, a very hot (X-ray emitting) gas pervading the large-scale structure of our Universe. This hot gas actually represents a huge fraction of the “ordinary” matter in galaxy clusters: more than 4 times the total mass of all their galaxies! In his talk, François will focus on a key connection between this intracluster medium and the fascinating world of stars, supernovae, and even supermassive black holes in galaxies.
Erik Osinga: “Clusters of galaxies through radio eyes”
Erik Osinga is a PhD student at Leiden University, studying clusters of galaxies. Clusters of galaxies are the largest collections of galaxies that are bound together by gravity. Erik uses radio telescopes such as the LOFAR telescope to study what happens when these huge objects collide with each other, that is to say: when multiple galaxy clusters merge. In his talk, Erik will focus on the many processes that happen during these mergers, that would be invisible to us were it not for radio telescopes.
Important information: All ages and backgrounds welcome! The entry is free but registration is required due to COVID-19 regulations set in place! By signing up, you are agreeing to follow the 1.5 metre social distancing rules, will not attend if you have any symptoms and will clean your hands upon arrival at De Burcht (disinfectant will be provided). Attendance is on the understanding that we have put in place meeting protocols yet cannot guarantee no risk of possible coronavirus infection. Due to the limited space, if you have registered but can no longer attend the event, please get in contact with us as soon as possible to allow other interested persons to attend. We hope to make the event accessible to all by also streaming it live on our YouTube channel.
We start at 8 PM sharp and recommend you arrive early to get to your seat and grab a drink. And of course, beside the talks, we will have fun games where you can win cool science prizes!
