CERN celebrates its 70th anniversary

Abstract

On 29 September this year, CERN, a European laboratory for particle physics, the place where the web was born in 1989 and the Higgs boson was discovered in 2012, celebrated its 70th anniversary. The impetus came from Louis de Broglie, a French theoretical physicist and 1929 Nobel Prize winner in Physics, who proposed the establishment of a European physics laboratory in 1949 to prevent the outflow of talented physicists to the US. 

Showers of cosmic rays may reveal new physics

Abstract

On open questions in astroparticle physics with Jakub Vícha

Where do high-energy cosmic ray particles come from and how can we even learn what they are? Can they open up an opportunity for us to discover completely new physical processes? And can cosmic rays influence the weather? These questions have not been answered yet, but research by Jakub Vícha from the Department of Astroparticle Physics at FZU is bringing us closer to unravelling these mysteries.

Atacama Desert will get hundreds of thousands of tons of water placed into. Scientists are looking for sources of cosmic rays

Abstract

The first ground-based wide-field observatory designed to detect very high to ultra-high energy gamma rays in the Southern Hemisphere will be built in the Atacama Astronomical Park in Chile. The observatory will study radiation from space that is emitted by the most extreme objects in the universe, such as black holes and neutron stars, gamma-ray bursts and supernovae.

Czech physicist Jakub Vícha's method helps determine what cosmic rays consist of

Abstract

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.

Eva Maria Martins dos Santos of the FZU received the Auger Impact Award 2023

Abstract

Dr. Eva Maria Martins dos Santos of the FZU received the Auger Impact Award 2023 on November 17 in recognition of the outstanding efforts on Monte-Carlo simulation coordination, which has a tremendous impact on the results published by the Pierre Auger Observatory but is not necessarily visible, and for her extremely responsive and service oriented attitude.

Miloš Lokajíček Jr.

Abstract

Our friend and colleague, Miloš Lokajíček, PhD, CSc., long-standing staff member of the Division of Elementary Particle Physics at the Institute of Physics of the CAS, passed away at the age of 70 on Wednesday, June 14th. Miloš was involved in almost all the key experiments in which we participated and contributed significantly to them, especially in the field of acquisition and processing of experimental data.

For Václav Vrba

Abstract

Václav Vrba, our classmate, friend and colleague passed away after a long illness on Tuesday, December 29. His life’s pilgrimage crossed ours in a number of places and for years in our working as well as personal lives and it is difficult for us to accept that it no longer will be so.

The World´s Largest Astrophysics Array 20th Anniversary

Abstract

This year marks the 20th anniversary since the founding agreement of the international Pierre Auger Observatory in Argentina has been signed. The celebration ceremony that took place last week in Malargüe was attended not only by a delegation of Czech scientists but also by the Czech Ambassador in Argentina Karel Beran.
