Faszination Astronomie: Ultrakalte Röntgendetektoren

In the organizer's words:

Atomic matter appears in the form of extremely hot plasmas inside stars, around neutron stars and black holes and as "gas" in the intergalactic medium. At the temperatures prevailing there in the megakelvin range, X-ray telescopes in Earth orbit offer the last opportunity to study the chemical elements and their state as highly charged ions spectroscopically. One such telescope is XRISM, the only one that has an X-ray microcalorimeter and can record the entire X-ray spectrum simultaneously.

At the MPIK, we operate a similar instrument from the Dutch space research organization SRON and use it to observe highly charged ions prepared in the laboratory, which are dominant in the hottest plasmas. The aim is to obtain precise physical parameters and calibration data for the diagnostics of the hottest astrophysical plasmas.

José Crespo is group leader at the Max Planck Institute for Nuclear Physics (MPIK), Heidelberg since 2001.
