Astro-GR@Paris 2010: Gravitational-wave and electromagnetic signatures of massive black hole binaries and extreme mass-ratio inspirals

TOPIC

ASTROPHYSICS, GENERAL RELATIVITY, DATA ANALYSIS

for gravitational wave and electromagnetic signatures of massive black hole binaries (MBHBs) and extreme/intermediate mass-ratio inspirals (EMRIs/IMRIs). Organised by Pau Amaro-Seoane and Ed Porter.

When LISA flies, it will provide us with an opportunity to detect gravitational waves from high redshift sources (z~ 20). Observations of MBHBs could provide invaluable information on galaxy formation models, while EMRI observations could provide information on the strong field regime around a Kerr black hole. As LISA will be a precision tool is determining when a possible merger may take place, it is important that the astrophysical and data analysis communities work hand in hand. With this in mind, the main topics of interest for the meeting will be

  1. Astrophysical modelling of EM/GW sources
  2. Modelling of strong field sources within General Relativity
  3. LISA Data analysis
  4. Early warning of possible mergers either from the data analysis or by EM detection

for MBHBs, EMRIs and IMRIs.
