Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping
Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

Galaxy Collisions Found to Activate Supermassive Black Holes, Euclid Data Shows
Astronomers using ESA’s Euclid telescope and AI analysis have found that merging galaxies are significantly more likely to host active supermassive black holes. The gravitational chaos of a collision drives gas toward the galactic core, igniting AGN activity. This discovery strengthens the link between galaxy interactions and the energetic proces...

ESA’s Euclid Telescope Charts Over a Million Galaxies in Landmark First Data
ESA’s Euclid space telescope has captured about 1.2 million galaxies in its first year, providing one of the most detailed wide-field surveys of the universe ever made. Covering distances up to 10 billion light-years, Euclid’s clear, expansive imaging is helping astronomers study galaxy shapes, mergers, dwarf galaxy populations, and the role of...

NASA’s James Webb Space Telescope Spots Rare Quintet of Galaxies From the Early Universe
Astronomers using JWST and Hubble have discovered JWST’s Quintet, a system of at least five merging galaxies just 800 million years after the Big Bang. This rare find shows how galaxies grew rapidly in the early universe and may explain how some became inactive so soon.

Milky Way To Collide With Its Largest Neighbour Andromeda? What New Study Said
Earlier, scientists believed the collision may destroy both galaxies, merging them into an elongated one.

When Two Massive Black Holes Merged And Went Flying Across Cosmos
The researchers propose that this ejection resulted from the collision of two galaxies, causing their central black holes to merge into a larger one.

Astronomers Spot Galaxy NGC 3640 With a Past of Consuming Smaller Galaxies
Recent observations of NGC 3640 reveal a history of merging with smaller galaxies. Located 88 million light-years away, the elliptical galaxy is suspected to be on a collision course with NGC 3641. The Very Large Telescope captured structural distortions, hinting at previous mergers. Researchers have identified ancient stars acting as fossil marker...

Astronomers Seek Binary Supermassive Black Holes in Galactic Centers
Astronomers have detected possible binary black holes at the centres of galaxies, using light patterns from active galactic nuclei as key indicators. The study of PG 1553+153, in particular, shows evidence of a 20-year variation, pointing to a system of two supermassive black holes. If confirmed, this could provide new insights into galaxy formatio...

Astronomers Uncover New Details of CIZA0107 Galaxy Cluster Merger with VLA
A team of astronomers, led by Emma Schwartzmann from the U.S. Naval Research Laboratory, used the Very Large Array (VLA) to study the nearby galaxy cluster merger CIZA J0107.7+5408 (CIZA0107). The observations provided new insights into the dynamics of galaxy mergers, revealing a disturbed system with two subclusters and diffuse radio emission span...

Ancient Galaxy Collisions May Explain Formation of Massive Early Star Systems
Research published in Nature reveals that ancient galaxy collisions may have led to the creation of the universe’s largest star systems. Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), scientists studied over 100 galaxies undergoing intense star formation. These collisions are believed to have occurred 8 to 12 billion yea...
