Tytuł:: Black holes: do they exist?
Autorzy:: Malec, Edward

first observations of black holes
present status of black holes
black holes
Opis:: Black holes entered scientific literature as early as at the end of eighteenth century. They had been known at that time as dark stars, but their concept did not find its way to physics or astronomy, and had been abandoned for more than one hundred years. I shall sketch historical developments and discuss present mathematical and observational status of black holes.

Tytuł:: Some remarks on the first image of a black hole

Opis:: On the 10th of April, 2019 the Event Horizon Telescope Collaboration presented the first image of the black hole. The image was obtained with a planet-scale array of eight ground-based radio telescopes. The observation relied on a technique called very long base interferometry which synchronises telescope facilities around the world. The image of a black hole together with the recent detections of gravitational waves confirms one of the most intriguing predictions of Einstein’s gravity theory, namely, the existence of black holes. I will provide more details on this remarkable observation and explore its consequences for our understanding of nature. The physical reality of black holes is strongly supported by recent advances of astronomy. I claim that this fact is the key to understanding the relation between our world and the world of mathematics.

Opis:: A short historical description of Polish contribution to astronomy and rocket technology is given. Then Polish activities in field of space exploration, such as instrument designed and build in Poland and placed on board of rockets, satellites and space probes during last 50 years are described. Contributions of the Space Research Center of the Polish Academy of Sciences as well as astronomical discoveries made by Polish astrophysicists are presented. Most important missions in which instruments build in Poland were placed on board are among others: Mars Express and Venus Express, Cassini-Huygens, Rosetta and Integral. Among numerous discoveries made by Polish astrophysicists, one should mention the discovery and proper identification of powerful burst from magnetar SGR 1806-20 and the discovery of unusually rapid bursts from black hole Cyg X-1.

Tytuł:: Joint detection of gravitational waves from binary black hole and binary neutron star mergers by LIGO and Virgo

Opis:: Advanced Virgo detector joined advanced LIGO twin detectors on 1st August 2017 in the quest to look for the gravitational waves. The global network of three detectors was operational for 25 days until the LIGO shut down on 25th August 2017. Two gravitational wave events were registered during this period. One of them was the binary black hole merger dubbed as GW170814 and other one is binary neutron star merger referred to as GW170817. Electromagnetic counterpart associated with binary neutron star merger was promptly identified which marks the beginning of multi-messenger astronomy. This article describes these events emphasizing on the crucial role played by the Virgo and focusing on some methodological issues.
