An arm length stabilization system for KAGRA and future gravitational-wave detectors
T. Akutsu, M. Ando, K. Arai +198
Modern ground-based gravitational wave (GW) detectors require a complex interferometer configuration with multiple coupled optical cavities. Since achieving the resonances of the a…
The Assembly of the First Massive Black Holes
Kohei Inayoshi, Eli Visbal, Zoltán Haiman
The existence of 10^9 Msun supermassive black holes (SMBHs) within the first billion year of the universe has stimulated numerous ideas for the prompt formation and rapid…
Application of the independent component analysis to the iKAGRA data
KAGRA Collaboration, T. Akutsu, M. Ando +244
We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, a…
Electromagnetic Window into the Dawn of Black Holes
Zoltán Haiman, William N. Brandt, Alexey Vikhlinin +28
Massive 10^6-10^10 Msun black holes (BHs) are ubiquitous in local galactic nuclei. They were common by the time the Universe is several Gyr old, and many of them were in place with…
Intermediate-Mass Black Holes in Extragalactic Globular Clusters
Joan M. Wrobel, Zoltan Haiman, Kelly Holley-Bockelmann +6
Intermediate-mass black holes (IMBHs) have masses of about 100 to 100,000 solar masses. They remain elusive. Observing IMBHs in present-day globular clusters (GCs) would validate a…
Transition of BH feeding from the quiescent regime into star-forming cold disk regime
Kohei Inayoshi, Kohei Ichikawa, Jeremiah P. Ostriker +1
We study the properties of rotating accretion flows onto supermassive black holes (SMBHs) using axisymmetric two-dimensional hydrodynamical simulations with radiative cooling and B…
Super-Eddington growth of black holes in the early Universe: effects of disk radiation spectra
Eishun Takeo, Kohei Inayoshi, Ken Ohsuga +2
We investigate the properties of accretion flows onto a black hole (BH) with a mass of embedded in an initially uniform gas cloud with a density of in ord…
