KAGRA is a second-generation interferometric gravitational-wave detector with 3 km arms
constructed at Kamioka, Gifu, Japan. It is now in its final installation phase, which we call …

The construction of the Japanese second-generation gravitational-wave detector KAGRA (previously
called LCGT) has been started. In the next 6–7 years, we will be able to observe …

We report the mirror suspension design for large-scale cryogenic gravitational wave telescope,
KAGRA, during bKAGRA phase 1. Mirror thermal noise is one of the fundamental noises …

KAGRA [1, 2] is a second-generation interferometeric Gravitational wave detector (GWD)
located in Gifu, Japan. The optcial confirguration of the detector is a dual-recycled Fabry Perot …

In 2015, two LIGO detectors had directly detected the gravitational wave (GW) from the black-hole
binary merger event, GW150914. In 2017, three detectors, including the Virgo detector…

Direct detection of the gravitational waves opened a new window to observe the Universe.
The recent observations have discovered astronomically important events such as the” mass-…

Gravitational wave detectors, such as KAGRA, require complex mirror suspension systems
to reach high sensitivity. One particular concern in these suspensions is the presence of …

Recent observations made with advanced LIGO and advanced Virgo have initiated the era
of gravitational-wave astronomy. The number of events detected by these'2nd generation'(2G…
