  14. Complete GW Classification (I) • Ultra high frequency band (above 1 THz): Detection methods include Terahertz resonators, optical resonators, and ingenious methods to be invented. • Very high frequency band (100 kHz – 1 THz): Microwave resonator/wave guide detectors, optical interferometers and Gaussian beam detectors are sensitive to this band. • High frequency band (10 Hz – 100 kHz): Low-temperature resonators and laser-interferometric ground detectors are most sensitive to this band. • Middle frequency band (0.1 Hz – 10 Hz): Space interferometric detectors of short armlength (1000-100000 km). • Low frequency band (100 nHz – 0.1 Hz): Laser-interferometer space detectors are most sensitive to this band.

  15. Complete GW Classification (II) • Very low frequency band (300 pHz – 100 nHz): Pulsar timing observations are most sensitive to this band. • Ultra low frequency band (10 fHz – 300 pHz): Astrometry of quasar proper motions are most sensitive to this band. • Extremely low (Hubble) frequency band（1 aHz – 10 fHz): Cosmic microwave background experiments are most sensitive to this band. • Beyond Hubble frequency band (below 1 aHz): Inflationary cosmological models give strengths of GWs in this band. They may be verified indirectly through the verifications of inflationary cosmological models. Galaxy-BH co-evolution, Dark Energy and GW detection W-T Ni

  22. LISA LISA consists of a fleet of 3 spacecraft 20º behind earth in solar orbit keeping a triangular configuration of nearly equal sides (5 × 106 km). Mapping the space-time outside super-massive black holes by measuring the capture of compact objects set the LISA requirement sensitivity between 10-2-10-3 Hz. To measure the properties of massive black hole binaries also requires good sensitivity down at least to 10-4 Hz. (2020) Galaxy-BH co-evolution, Dark Energy and GW detection W-T Ni

  23. Primordial Black Holes • Planck Mass BHs (formed at the Planck epoch) to solar mass (M⊙) BHs (formed at the QCD phase transition) up to 105M⊙ BHs • Physical or Astrophysical Constraints (i) BH mass < 5 x 1014 g: already evaporated due to Hawking radiation; (ii) BH mass about 1015 g: contribution to matter density less than 10-8 (constraints from diffuse gamma ray background; (iii) BH mass below about 103 (constraints from microlensing and CMB distorsions) Galaxy-BH co-evolution, Dark Energy and GW detection W-T Ni

  26. Models of formation of massive black hole binary systems (1) • (i) the VHM model (Volonteri, Haardt & Madau 2003), • (ii) the KBD model (Koushiappas, Bullock & Dekel 2004), • (iii) the BVRhf model (Begelman, Volonteri & Rees 2006) and • (iv) the VHMhopk model. • In these scenarios, seed black holes are massive (M ∼ 104 M⊙) as in the case of KBD and BVRhf, or light (M ∼ 102 M⊙), as prescribed by VHM; seed black holes are abundant (VHM, KBD) or just a few (BVRhf). • The VHMhopk model assumes essentially the same assembly history of the VHM model, but with a somewhat different accretion prescription (Volonteri, Salvaterra & Haardt 2006). Galaxy-BH co-evolution, Dark Energy and GW detection W-T Ni

  27. Models of formation of massive black hole binary systems (2) • the merger hierarchy of 220 dark matter halos in the mass range 1011 − 1015 M⊙ up to z = 20 (Volonteri, Haardt & Madau 2003), then populating the halos with seed black holes and following their evolution to the present time. • For each of the 220 halos all the coalescence events happening during the cosmic history are collected. The outputs are then weighted using the EPS (Extended Press-Schechter) halo mass function and integrated over the observable volume shell at every redshift to obtain numerically the coalescence rate of MBHBs as a function of black hole masses and redshift. • the outcome of this procedure is the numerical distribution d3N/dzdMdt.
