Gravitational lenses - a gold mine for astronomers
How does gravitational lensing affect gravitational waves?
What do lensed gravitational waves tell us?
Are any of the recent detections gravitationally lensed?
Apart from this, various researchers of LISC are involved in multiple lensing projects, which will benefit the collaboration, and the new analyses might be included in future LIGO-Virgo-KAGRA (LVK) publications. LISC researchers continue to contribute in the various aspects of the LVK collaboration efforts and the strong presence of Indian researchers is a good indication of the preparedness for the upcoming LIGO-India project.
- Black Hole: A massive dense object whose gravitational pull is so strong that light cannot escape.
- Compact binary: A system of two stellar remnants (a neutron star or a black hole) orbiting each other closely.
- Gravitational-wave polarisation: The geometric shape of the stretching and squeezing of spacetime caused by a gravitational-wave as it moves.
- Distant universe: Due to the finite speed of light, the further we look into the distant universe, the further we also look back in time.
- Stochastic Gravitational waves: A background “noise” of gravitational wave signals which arises due to various processes from different directions, for example, the waves produced in the earliest phases of big bang or weak signals produced by populations of compact binaries in the Universe.
