Search for a stochastic background of 100-MHz gravitational waves with laser interferometers
Tomotada Akutsu, Seiji Kawamura, Atsushi Nishizawa +11
This letter reports the results of a search for a stochastic background of gravitational waves (GW) at 100 MHz by laser interferometry. We have developed a GW detector, which is a…
Optimal Location of Two Laser-interferometric Detectors for Gravitational Wave Backgrounds at 100 MHz
Atsushi Nishizawa, Seiji Kawamura, Tomotada Akutsu +8
Recently, observational searches for gravitational wave background (GWB) have been developed and given constraints on the energy density of GWB in a broad range of frequencies. The…
Constraints on Primordial Black Holes by Distortions of Cosmic Microwave Background
Hiroyuki Tashiro, Naoshi Sugiyama
Possible influence of primordial black hole (PBH) evaporations on cosmic microwave background (CMB) is investigated. The spectrum distortions of CMB from the black-body spectrum ar…
