LISA compliments LIGO
![Page 5: LISA and Beyond Neil Cornish Louis Rubbo, Seth Timpano & Jeff Crowder](https://reader036.vdocuments.net/reader036/viewer/2022062313/56649d0c5503460f949e0c10/html5/thumbnails/5.jpg)
LISA = LIGO in Space/
Synthetic vs. Fabrey-Perot Interferometery Wavelengths comparable to size of detector Free running vs. locked (Hetrodyne detection)
Key Technologies Accelerometers (disturbance reduction system) Ultra stable lasers and clocks

Astrophysical Information Encoded in Time Series
Internal Parameters
External Parameters
Time series depends on many source parameters
Can estimate parameter resolution using Fisher Information Matrix (Cutler, Hellings & Moore, Vecchio, Seto, Hughes)
Many parameters highly correlated (Cutler) Many sources that interfere (Cornish & Crowder)

The Future is in GEMSGravitational-ElectroMagnetic Sources
• Break Degeneracies• GW : EM (Spc. Binaries)
• Cover Gaps• GW : EM (SMBHB)• GW : EM (LMXBs)
• Verify Source Identity
Can we identify optical counterparts to LISA sources?

ConclusionsMany science drivers will shape future detectors. In almost every case improved angular resolution and electromagnetic counterparts will be very valuable.
