主持人/Host: 陶炼/Lian TAO

摘要/Abstract: After briefly summarising the results of the gamma-ray burst detectors on the GRBAlpha and VZLUSAT-2 CubeSats, I will present the status and summarise the science case of the Quick Ultra-Violet Kilonova surveyor—QUVIK mission. QUVIK is an ultra-violet (UV) space telescope on an approximately 130 kg small satellite with a moderately fast re-pointing capability and a real-time alert communication system, approved for a Czech national space mission. The satellite, which is expected to launch in five years, will provide key follow-up capabilities to increase the discovery potential of gravitational wave observatories and future wide-field multi-wavelength surveys. The primary objective of the mission is the measurement of the UV brightness evolution of kilonovae, resulting from mergers of neutron stars, to distinguish between different explosion scenarios. The mission, which is designed to be complementary to the Ultraviolet Transient Astronomy Satellite—ULTRASAT, will also provide unique follow-up capabilities for other transients both in the near- and far-UV bands. Between the observations of transient sources, the satellite will perform observations of other targets of interest for the scientific community, such as stars, stellar systems, and galactic nuclei.

个人简介/Biography：

Norbert Werner is an astrophysicist, a professor and the leader of the High-Energy Astrophysics research group in the Department of Theoretical Physics and Astrophysics at Masaryk University, Brno, Czech Republic. He is mainly interested in the hot atmospheres of galaxies and clusters of galaxies, black hole feedback, and in the use of nano-satellites in astrophysics.

Norbert earned his PhD at the Netherland's Institute for Space Research and Utrecht University in 2008, where he mainly worked on the physics and chemical enrichment of the hot gas permeating clusters of galaxies and the cosmic web. Then he spent 8 years at Stanford University, in the beautiful San Francisco Bay Area, mainly studying the influence of supermassive black holes on the hot gaseous haloes, investigating the faint and mysterious cluster outskirts, and working on preparations for the science with the Japanese ASTRO-H/Hitomi satellite. Between 2016 and 2020 he was the leader of the MTA-ELTE Lendulet Hot Universe research group in Budapest, where he helped to initiate the development of CubeSats to detect gamma-ray bursts. Norbert and his team now continue their research activities in the Department of Theoretical Physics and Astrophysics thanks to the MUNI Award in Science and Humanities (MASH) grant from Masaryk University and an EXPRO grant from the Czech Science Foundation.
