New link found between mass of Supermassive black holes and their host galaxies

A team of astronomers has discovered a novel way to “weigh” supermassive black holes at the centres of galaxies by measuring the distances between the galaxies that contain them. Mysterious, massive dark objects lurk at the centre of nearly all galaxies and can be observed with high enough sensitivity. Astronomers believe these to be black … Read more New link found between mass of Supermassive black holes and their host galaxies

Massive filaments fuel the growth of galaxies and supermassive black holes

An international group of scientists led by the RIKEN Cluster for Pioneering Research have used observations from the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT) in Chile and the Suprime-Cam at the Subaru telescope to make detailed observations of the filaments of gas connecting galaxies in a large, distant proto-cluster … Read more Massive filaments fuel the growth of galaxies and supermassive black holes

Oldest galaxy protocluster forms ‘queen’s court’

Using the Subaru, Keck, and Gemini Telescopes, an international team of astronomers has discovered a collection of 12 galaxies which existed about 13.0 billion years ago. This is the earliest protocluster ever found. One of the 12 galaxies is a giant object, known as Himiko, which was discovered a decade ago by the Subaru Telescope … Read more Oldest galaxy protocluster forms ‘queen’s court’

Researchers discover that a giant smash of galaxy clusters forms bar structure in spiral galaxies

Researchers in Korea reported in 2019 June 24th issue of Nature Astronomy that a giant smash of two clusters of galaxies can form bar structure, an important structure inside many spiral galaxies. It has been known that galaxies, systems made of hundreds of billions of stars, can take many different shapes. The reason why galaxies … Read more Researchers discover that a giant smash of galaxy clusters forms bar structure in spiral galaxies

Galaxy clusters caught in a first kiss

For the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing ‘piece of the puzzle’ in our understanding of the formation of structure in the Universe, since large-scale structures—such as galaxies and clusters of galaxies—are thought to grow by collisions … Read more Galaxy clusters caught in a first kiss

Distant and ancient

Dotted across the sky in the constellation of Pictor (The Painter’s Easel) is the galaxy cluster highlighted here by the NASA/ESA Hubble Space Telescope: SPT-CL J0615-5746, or SPT0615 for short. First discovered by the South Pole Telescope less than a decade ago, SPT0615 is exceptional among the myriad clusters so far catalogued in our map of the Universe – it is the highest-redshift … Read more Distant and ancient
