How many people work at LIGO?
The LIGO Laboratory is the largest member of the LIGO Scientific Collaboration (LSC). Established in 1997, the LSC includes over 1200 scientists from over 100 institutions in 18 different countries.
Who worked on LIGO?
Barish ushered LIGO through its final design stages and secured funding through NSF’s National Science Board. He oversaw construction of the two LIGO facilities from 1994 to 1999, and then the installation and commissioning of the initial LIGO interferometers from 1999 to 2005.
What is the LIGO Scientific Collaboration working on?
The LIGO Scientific Collaboration (LSC) is a group of scientists focused on the direct detection of gravitational waves, using them to explore the fundamental physics of gravity, and developing the emerging field of gravitational wave science as a tool of astronomical discovery.
What is the LIGO Virgo collaboration?
Most prominently, LIGO closely collaborates with Virgo, a 3 km gravitational wave interferometer located near Pisa Italy. Data from LIGO and Virgo are combined and analyzed jointly by the LIGO and Virgo groups. This collaboration significantly enhances the search for gravitational waves.

Who paid for LIGO?
LIGO is funded by NSF and operated by Caltech and MIT, which conceived of LIGO and led the Initial and Advanced LIGO projects.
Who is the founder of LIGO?
The very idea for LIGO came to Rainer Weiss in the early 1970’s when, as associate professor of physics at MIT, he had to find a way to explain gravitational waves (a prediction of general relativity) to his students.
Is India part of LIGO?
LIGO-India is a collaboration between the LIGO Laboratory (operated by Caltech and MIT) and three Institutes in India: the Raja Ramanna Center for Advanced Technology (RRCAT, in Indore), the Institute for Plasma Research (IPR in Ahmedabad), and the Inter-University Centre for Astronomy and Astrophysics (IUCAA, in Pune) …
How many detections has LIGO?
Observations are made in “runs”. As of January 2022, LIGO has made 3 runs (with one of the runs divided into 2 “subruns”), and made 90 detections of gravitational waves….LIGO.

What is the future of LIGO?
Soon, astronomers say, LIGO will record and unveil far more than the birth cries of newborn black holes. It and other operational observatories are already looking for ripples from the violent death throes of massive stars and from collisions of city-size orbs of degenerate matter called neutron stars.
Is LIGO still operating?
LIGO resumes work in 2023 and will catch gravitational wave signals fainter than ever. The gravitational wave detector will be able to spot neutron star mergers as distant as 620 million light-years away.
How many interferometers does LIGO have?
LIGO currently consists of two interferometers, each with two 4 km (2.5 mile) long arms arranged in the shape of an “L”. These instruments act as ‘antennae’ to detect gravitational waves.
How many LIGO are there in the world?
A Nation-Wide Research Facility Although it is considered one observatory, LIGO comprises four facilities across the United States: two gravitational wave detectors (the interferometers) and two university research centers.
How expensive is LIGO?
The observatory, which will cost 12.6 billion rupees (US$177 million) and is scheduled for completion in 2024, will be built in the Hingoli District of Maharashtra state in western India.
Why does LIGO use two interferometers?
Using Multiple Detectors Multiple interferometers are needed to confidently detect and locate the sources of gravitational waves (except continuous signals), since directional observations cannot be made with a single detector like LIGO, which is sensitive to large portions of the sky at once.
