RATOP2020 — Relativistic astrophysics, Theory and observational perspectives
16 jui 2020 - 19 jui 2020 • Varsovie, Pologne
Organisateur:
Center for Theoretical Physics, Polish Academy of Sciences
Résumé:
Theoretical studies have shown that the muti-wavelength emission in the nuclei of the active galaxies, and black hole binaries, is fueled by their accretion disks. The magnetic fields therein must mediate the transfer of mass and angular momentum. In addition, shock waves, possibly related to the regions tidally excited by the companion star in a binary system, may influence the accretion process and observed flaring emission. Finally, the episodes of jets being launched from the central engines, in both radio-blazars and in gamma ray bursts, are giving important insight into the physics of black hole accretion, and help estimate the fundamental parameters of the black holes, such as their masses and spins. These effects are studied by advanced numerical simulations, that use the methods of general relativistic magnetohydrodynamics.

Theoretical investigations are verified experimentally through the timing and spectral properties of the observed sources. In the last years, the observational context has been enormously enhanced due to discovery of gravitational waves, which give independent constraints on the masses (and possibly spins) of the merging compact stars. The multi-wavelength detection of accompanying events of the short GRBs, such as the kilonovae, have brought further important information about the conditions within the post-merger environment. Finally, the fundamental theories of gravity can be tested now with unprecedented precision through the signals from compact objects, such as quasars, supernovae, and gravitational-wave sources.

5th Cosmology School — 5th Cosmology School „Introduction to Cosmology”
18 jul 2020 - 02 aou 2020 • Cracovie, Pologne
Organisateur:
Astronomical Observatory of the Jagiellonian University
Résumé:
The 5th Cosmology School „Introduction to Cosmology” is the continuation of the series of cosmology schools of which the last one took place in 2018 in Cracow. It is an event aimed at giving an introduction to the current knowledge in cosmology, both in theory and observations.

Summer School — Formation and evolution of planetary systems and habitable planets
19 aou 2020 - 26 aou 2020 • Torun, Pologne
Organisateur:
Faculty of Physics, Astronomy and Informatics of the Nicolaus Copernicus University in Torun, Poland
Résumé:
The idea behind the school is to gather people from different backgrounds, incl. astronomy, geology, biology, physics, journalism and teaching, and provide them with the opportunity to work in multidisciplinary groups on solving scientific problems.The program of the school will include joint lectures - from protoplanetary discs and exoplanets to geologic features of the surfaces of Earth and Mars - and afternoon hands-on sessions in small, interdisciplinary groups. Participants will present posters and flash talks about their work at the beginning of the school. Presentations by groups of students about the results obtained as part of the school are schedules at the final day of the school.
