Gravitational Waves From The Capture of Compact Objects And Observations Of The Galactic Centre
ASTROPHYSICS, GENERAL RELATIVITY, AND OBSERVATIONAL ASTRONOMY OF THE GALACTIC CENTRE
from/for/aiming at understanding the capture of compact objects by massive black holes.
Organised by Pau Amaro-Seoane, Leor Barack, Vítor Cardoso, Wlodek Kluzniak, Harald Pfeiffer and Xian Chen, at the posadas de Alájar and San Marcos, in Alájar, to be pronounced phonetically [ a ‘la xar ], Andalusia, from Aug 25 – Sep 4 2019.
The Laser Interferometer Space Antenna (LISA) will look for GW signals in the low-frequency band (0.1 mHz – 1 Hz). We will focus on the capture of small compact objects by supermassive black holes, and on observations of our Galactic Centre, a proxy in a sense. Considering the possible existence of intermediate-mass black holes, an additional source of gravitational waves for LISA will the inspiral of stellar-mass compact objects into an IMBH or the inspiral of an IMBH into a MBH. These sources, again due to the mass ratio of the binaries, are known as an intermediate-mass ratio inspirals (IMRIs).
