Autoři obrázku: Richard White, MPIK První pozemní širokoúhlá observatoř určená k detekci velmi vysokých až ultra vysokých energií gama záření na jižní polokouli vyroste v Astronomickém parku Atacama v Chile. Observatoř bude studovat záření z vesmíru, které je emitováno nejextrémnějšími objekty ve vesmíru, jako jsou černé díry a neutronové hvězdy, gama záblesky a supernovy.

Enthusiasm for science is the driving force behind success. This is also demonstrated by Lindau Meetings, where for decades young scientists from all over the world have been meeting Nobel laureates. "The atmosphere of togetherness and mutual support they experience there is an invaluable source of inspiration," says this year's participant Petr Veřtát, a postdoctoral fellow from the Department of Magnetic Measurements and Materials at the Institute of Physics of the Czech Academy of Sciences.

We invite you to an in-house seminar by Anne Gärtner from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF, which will take place on Friday 16 August at 10 am in the PERLA Seminar Room.

Scientists from the Joint Laboratory of Optics, a collaboration between Palacký University and the Institute of Physics of the Czech Academy of Sciences, have significantly refined and improved the efficiency of quantum entanglement tests, which play a crucial role in the development of quantum computers, by incorporating artificial intelligence. Their research results were recently published in the prestigious journal Physical Review Research.

From 4 to 10 November 2024, the Week of the Academy of Sciences of the Czech Republic will take place. During this event, you can attend lectures and workshops organized by many institutes of the Academy of Sciences.We are traditionally involved in the event and are preparing for you Open Days for schools and the public, which will take place at the Na Slovance and Cukrovarnická sites from 7-9 November.

This year, we will also participate in the national event Researchers’ night, during which hundreds of scientific buildings will come alive! You can look forward to excursions, a mobile planetarium, a fun zone and we are preparing two big surprises that we will gradually reveal. The theme of this year's event is Transformation!

Experience Ořechovka differently! Once again, after a year, we are going to play with physics. Get to know your neighbours and friends while sitting in the outdoor café and practice yoga together. We are preparing the program for you.

Jiří Hybler (15. 4. 1949–25. 7. 2024) Image Jiří Hybler studied geology at the Faculty of Science and was directed to crystallography, which was then beginning to develop rapidly in our country, by Professor Jiří Novák. He put him in contact with Associate Professor Syneček in the Metals Department of the then Institute of Solid State Physics in Cukrovarnická, where Jiri started his career. 

Cosmic strings are predicted in many particle physics models beyond the Standard Model. If such a model describes our universe, a network of strings inevitably forms in the early universe and persists to the present time. Cosmic strings lead to nonlinear density fluctuations at early times and will dominate the nonlinear structure at high redshifts. I will discuss how cosmic string loops dominate the halo mass function and can lead to early galaxy formation and to the formation of supermassive black holes at high redshifts. Long string segments lead to wakes which leave behind characteristic imprints in 21-cm redshift maps.

Eleven enthusiastic students from high schools in and around Olomouc participated in the Summer School of Optics, which was organized for the tenth time by the Joint Laboratory of Optics. A week full of science allowed them to take a peek into the secrets of optics and get acquainted with the latest findings in this promising field. Image Show all 7 photos

The latest episode of the popular series Undistorted Science focuses on a key topic of our time – the photovoltaic harnessing of the Sun's energy.  

Abstract:  The Pierre Auger Observatory is the world's largest detector of ultrahigh-energy cosmic rays (UHECRs). The data, unrivaled in quality and statistics, collected by the observatory over nearly two decades greatly shaped the current state of UHECR physics. We review this impact using the most recent highlights from the Pierre Auger Observatory on the UHECR energy spectrum, mass composition, arrival directions, nuclear interactions, searches for neutral particles and multimessenger physics.  However, progress in our understanding of the UHECR properties has led to a complex picture with new challenges for discovering the UHECR origins. On this account, we discuss the nearly completed upgrade of the Pierre Auger Observatory (dubbed AugerPrime) and its potential to address these challenges during the next decade.   The seminar will be held in the main conference hall, Institute of Physics, Na Slovance 2, Prague 8.

The highest energy cosmic ray particles are likely to penetrate much deeper into the atmosphere than previously thought. The incoming particles are therefore likely to be much heavier. New and fundamental insights emerge from a method that generalises the approach to predicting models of cosmic particle collisions with the Earth's atmosphere. The accuracy of Jakub Vícha's method has been confirmed by hundreds of international scientists at the Pierre Auger Observatory, as shown in a study published these days in Physical Review D.
