The meeting took place on Wednesday 9 April in Spořilov. Its first part focused on the restructuring of the LISA Consortium, where Ondřej Zelenka summarized the principles of operation of the new consortium and its implications for the Czech member group.

In the second part, Lukáš Polcar presented a talk titled Adiabatic inspirals into a black hole surrounded by matter calculated using a modified Teukolsky equation. Afterwards, Paola Delgado presented her work in the talk Testing gravitational wave polarizations with LISA.

Our spring czechLISA meeting will take place on Monday 11.3.2024 at the:

Adéla Kochanovská large lecture hall (SOLID21)                                                       Institute of Physics of the Czech Academy of Sciences    Pod vodárenskou věží 2531/3, Praha 8, Czech Republic

Apart from scientists and students from Czech Republic interested in the LISA mission, we would like to invite LISA/ESA members visiting Prague for the IDS Project Manager Meeting 12.-13.3.2024, so we might have a fruitful interaction during the czechLISA meeting.
