Flashes of gravitationally lensed starlight could act as cosmic lighthouses revealing the presence of binary supermassive ...

Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion ...

Astronomers propose a new method to detect hidden supermassive black hole pairs using warped starlight, offering early clues before gravitational wave signals arrive.

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.
