Gravitational waves associated with known astrophysical
Albert-Einstein-Institut, Max-Planck-Institut für
this lecture I introduce the generic reasons behind the improvement in
GW sensitivity from external triggers, and how it is limited by EM
phenomenology and observation capabilities. I show how astrophysical
models of gamma-ray bursts and soft gamma repeaters guide the
construction of EM triggered GW searches, and what data analysis
techniques are enabled by the presence of an external trigger. I
conclude with several examples of astrophysical statements that could
be determined by EM triggered GW detection.
external triggers help finding GWs ?
astrophysical models of EM and GW emission define the search parameter
analysis techniques that are enabled by external triggers
of potential astrophysical conclusions from EM triggered GW discoveries
gravitational wave (GW) searches are performed as followups of
electromagnetic (EM) observations of astrophysical events, such as
gamma-ray bursts, soft gamma repeaters or pulsar glitches. The presence
of an astrophysical trigger allows the detection of weaker GWs and a
richer result interpretation compared to blind all-time all-sky GW
