Czech Science Café: Czech Scientists and the World’s Largest Astrophysical Observatory

Join us for a talk on the construction and principles of the Pierre Auger Observatory (PAO) a cosmic ray observatory in Argentina, spiced up with fresh shots from the presenter’s last trip. Followed by a Q&A with the presenter, material physicist Jan Tomáštík, PhD. At the PAO a group of international scientists (including Czechs) now study the most distant mysteries of space through a telescope whose area is roughly three times that of New York City.



Czech Scientists and the World’s Largest Astrophysical Observatory

with Jan “JaRon” Tomáštík, Ph.D.

May 28 EDT, 2020, 7 pm, On-Line via ZOOM 



Jan “JaRon” Tomáštík, PhD, is a material physicist from Palacký University in Olomouc and the Czech Academy of Sciences. Thanks to a Fulbright-Masaryk scholarship, he is currently performing research at Virginia Tech University in Blacksburg, VA. However, he is also an active science popularizer, co-creator of the project Vedator (The Science Guy), which is the most followed pop-science project on Czech Facebook, also with its own Youtube Channel, Instagram, and website. He has been traveling with his science and pop-science lectures to schools, universities, and observatories for the past several years.

Did you know that…

15 out of 27 fluorescence detectors (FDs) of the Argentinian Pierre Auger Observatory were produced in the Czech Republic, specifically in Olomouc?

Olomouc Joint Laboratory of Optics of Faculty of Science of Palacký University and Institute of Physics of the Academy of Sciences of the Czech Republic (JLO) is characterized not only by possibly the longest name of a laboratory in the world, but also by the tradition of manufacturing sensitive optical elements. Thanks to the know-how from two important Czech research organizations and thanks to the experience transferred from the famous company Meopta Přerov, JLO was able to satisfy Pierre Auger Collaboration demands on quality, price, and speed of production. Czech mirrors are located in Coihueco and Loma Amarilla, two of four fluorescence detector buildings. Each fluorescence detector (FD) consists of 6 telescopes, or "eyes," looking in 180 degrees at the atmosphere above the surface detectors (SDs). Each mirror mesh is then comprised of a fly-eye style of 60 hexagonal segments. Olomouc supplied almost 1,000 mirrors to Argentina, including spare ones. Czech scientists nowadays regularly travel to Argentina to check the condition of mirrors and measure their reflectance.



Science Café is a new series of popular science presentations and talks by the best Czech scientists of today presented by the Czech Center New York. Inspired by the phenomenon of Cafe Scientifique which was first established in the UK in 1998 and spread across the world as a place where anyone could come to discuss the latest ideas in science and technology over a cup of coffee or a glass of wine, Science Café is an informal forum for the discussion of current work and interesting scientific issues.

Come and mingle with people with different interests while enjoying a cup of coffee or tea. An informal presentation from the speaker introducing the topic will be followed by a discussion where everyone will have an opportunity to ask questions.
