Einstein Telescope: a 3rd-generation gravitational-wave detector
Abstract
Einstein Telescope (ET) is a planned ground-based 3rd generation interferometer, whose sensitivity will cover a wider frequency range than the one currently covered by the existing gravitational-wave detectors. This will allow it to detect the signals from a various collection of sources and to test general relativity and fundamental physics. In this talk, I will give a brief overview of the ET project and discuss its scientific potential.

Search for Gravitational Waves at Low Frequencies
Abstract
The performance of the current and future ground-based detectors is severely limited at low frequencies
due to steeply rising seismic noise. LISA (Laser Space Interferometer Antenna) is a space-based
ESA led mission to be launched in 2035. It will operate in the milli-Hz band. In this presentations
I will give a latest update on the mission status and its objectives.
The International Pulsar Timing Array – a consortium of several regional collaborations – is aiming at detecting
gravitational waves in the nano-Hz band. I will present the latest result pointing at a strong evidence of
detecting GWs by PTAs and briefly discuss their origin.

Czech contribution to international scientific space missions
Abstract
I will review the Czech participation in the international scientific space missions, mainly led by the European Space Agency, including the space gravitational-wave observatory LISA. I will discuss the supporting programmes for these projects that include the ESA PRODEX and also support of the Czech Academy of Sciences.

Prague waveform group
Abstract
I will provide summary of waveform modelling efforts of the groups at Charles University and Astronomical Institute CAS. This includes in particular the breaking of integrability in orbital dynamics and its imprint in gravitational waves, and the effect of secondary spin in large mass ratio inspirals.

A secondary black-hole under collisions with an accretion disc
Abstract
The long-term evolution of the orbit of a satellite black hole captured by a massive galactic nucleus is examined. Repetitive transits across the accretion disk slab create a turbulent wake that needs to be further studied in order to estimate the effects of dragging and the amount of material pushed out of the disk plane. The hydrodynamical drag competes with the orbital decay by gravitational waves.

Constraining equation of state of dense matter using gravitational waves
Abstract
Neutron stars are laboratories that enable us to study the behaviour of nuclear matter at densities that are up to ten times higher than those in atomic nuclei. In this talk, I will briefly review universal relations among neutron star parameters and their role in the study of neutron stars. Finally, I will discuss constraints on dense matter coming from observations of gravitational waves, especially ones coming from GW170817.

Gravitational Radiation outgoing from ČSR, ČSSR, ČSFR, ČR
Abstract
A brief overview of selected topics in the gravitational radiation
theory investigated in our country in the last >70 years will be given.
These topics include plane waves, cylindrical waves, boost-rotation
symmetric spacetimes, Robinson-Trautman spacetimes, cosmological models
with gravitational waves, dragging of inertial frames by gravitational
radiation etc.
