cosmological sources inflation
Cosmological Sources: Inflation
  • Detectors
    • LISA/LIGO parametric amplification
    • WMAP
    • BICEP
  • Prediction: In 20 years...
    • Polarization of CMB
    • 1 million redshifts
cosmological sources cosmic strings
Cosmological Sources: Cosmic Strings
  • LIGO may detect cusps of superstrings
    • String tension, mean reconnection probability
    • SDSS, WMAP, parametric amplification
  • If detected, will push on numerical simulations of string networks.
  • Stochastic background from kinks, detected by pulsar timing

cosmological sources dark energy
Cosmological Sources: Dark Energy
  • SMBH binaries as standard candles.
  • Interplay with Type Ia supernovae
extragalactic sources massive black holes
Extragalactic Sources: Massive Black Holes
  • LISA will detect them as stuff falls in and gets ripped apart.
  • Follow-up game
  • Can we confirm the M-sigma relationship?
extragalactic sources mbh mbh binaries
Extragalactic Sources: MBH-MBH binaries
  • Detectable both as a background by PTA and by LISA as individual sources (LISA may predict what PTA will see)
  • Follow-up game – jets
  • Standard candles
extragalactic sources gamma ray bursts
Extragalactic Sources: Gamma-ray bursts
  • A possible source of GW.
  • Can you play the follow-up game?
galactic sources supernovae
Galactic Sources: Supernovae
  • LIGO will detect core collapse supernovae.
  • Bounce
  • Convection
  • Rotation
  • Neutrino emission
  • Asymmetries -> kicks -> optical follow-up
  • Neutron stars emerging?

Thanks Adam Burrows

galactic sources lmxbs
Galactic Sources: LMXBs
  • Seem to be some dispute about whether we'll see these?
  • Combination of EM and GW observations will tell you about neutron star crust strength and structure.
galactic sources ns ns inspirals
Galactic Sources: NS-NS inspirals
  • Double pulsar system (J0737-3039) By 2024 at least a handful of double pulsar systems will be known.
  • Follow-up game?
  • Standard candles
    • Measure mass of the neutron star
    • Free electron density of galaxy
  • Galactic populations of NS-NS binaries (Kalogera)
galactic sources stellar binaries
Galactic Sources: Stellar Binaries
  • Mike Eracleous will talk about these.
galactic sources triaxiality of neutron stars
Galactic Sources: Triaxiality of Neutron Stars
  • Timing noise may be detectable in a few dozen pulsars by Advanced LIGO (D. I. Jones)
summary
Summary
  • Cosmological sources of GW waves give another way of measuring what are elusive parameters.
  • Models of active galaxies, gamma ray bursts, supernovae, and neutron stars may be greatly enhanced in conjunction with EM observations.
  • Binaries as standard GW candles (MBH-MBH, NS-NS) will provide cosmological constraints, and constraints on free electron density in our galaxy.
  • When the objects are easier to detect in GWs than via EM waves the GW detections will constrain population studies greatly and most likely implicate corrections that EM observers will have to make.
