Zapraszamy na wykład specjalny z cyklu “Spotkania z Astronomią”. Raz w sezonie organizujemy wykład w języku angielskim (z opcją automatycznie tłumaczonych napisów dla uczestników na Zoom).
Tym razem wykład wygłosi Dr. Matteo Guainazzi z Europejskiej Agencji Kosmicznej (European Space Agency, ESA).
Formy udziału:
– na miejscu, w sali wykładowej na ul. Bartyckiej 18 w Warszawie, uczestnicy otrzymają gratis książkę “Across the Universe. Research at the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences”,
– przez Zoom, dostępne automatycznie tłumaczone napisy w języku polskim (i innych),
– poprzez YouTube.
Streszczenie: Black holes lurk everywhere in the cosmos. They shape the evolution of the galaxies hosting them, constitute unique laboratory of extreme physics, and could contribute to the elusive “dark matter”. Being “dark”, Humankind has been able only very recently to take direct “images” of their shadow. However, their surroundings are far from being “dark”: they are copious sources of high-energy radiation, X-rays and γ-rays. Space observatories of the European Space Agency (ESA) have been chasing these signals for decades, and the Polish scientific community has given a key contribution to their understanding. Furthermore, pairs of black holes dancing around each other trigger ripples in the space-time fabric: gravitational waves, which Humankind has also recently learned to decode. ESA is preparing the first space-born mission to listen to the gravitational cry of black holes in the last phases of their dramatic merging. How can we “see” the “invisible” black holes? What have they taught us on the history of the Universe? How does matter behave under the extreme physical conditions in their surroundings? These will be amongst the questions that I will address in my talk.
