I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars. http://drbecky.uk.com https://rebeccasmethurst.co.uk

When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA's Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups. Astronomers want to learn more about galactic collisions because the subsequent mergers are a key way that galaxies and the giant black holes in their cores grow over cosmic time. There have been many studies of what happens to supermassive black holes when two galaxies merge, but this is one of the first to systematically look at what happens to black holes when three galaxies come together. Researchers identified triple galaxy merger systems by cross-matching the archives — containing data that is now publicly available — of NASA's WISE mission and the Sloan Digital Sky Survey, or SDSS, to the Chandra archive. By doing this, they found seven triple galaxy mergers located between 370 million and one billion light years from Earth. Using specialized software developed, the team went through Chandra data targeting these systems to detect X-ray sources marking the location of growing supermassive black holes. As material falls toward a black hole, it gets heated to millions of degrees and produces X-rays. Chandra, with its sharp X-ray vision, is ideal for detecting growing supermassive black holes in mergers. The associated X-ray sources are challenging to detect because they are usually close together in images and are often faint. The new software was developed specifically to find such sources. Data from other telescopes was then used to rule out other possible origins of the X-ray emission unrelated to supermassive black holes. The results show that out of seven triple galaxy mergers there is one with a single growing supermassive black hole, four with double growing supermassive black holes, and one that is a triple. These black holes are separated by a range between 10,000 and 30,000 light years. In the final triple merger, there was no evidence of X-ray emission. This means that none of the supermassive black holes left was rapidly pulling in matter. Astronomers will continue to use Chandra to learn more about what role mergers play in how galaxies and the giant black holes in their centers grow over cosmic time.

We describe what it means for galaxies to collide given the great distances between stars within each galaxy. We then take a look at some of the interacting galaxies photographed by the Hubble Telescope. These include: The Antennae Galaxies, The Mice, NGC 2207 with IC 2163; Apr 256; ESO 576-69; APR 142; NGC 6240; the Tadpole Galaxy; UCG 1810 with UCG 1813; the spectacular APR 147; NGC 454; South America Galaxy; and ZW II 28. We spend some time on peculiar galaxy NGC 7603 with its multiple red-shift objects that challenge well accepted theories on Dark Matter and Cosmology. Next, we discuss how we go about seeing a process that takes a billion years by observing interactions at various stages along the process as understood by computer simulations. Here we show a few that illustrate the phases of an interaction: the initial approach with NGC 6786 and LEDA 62867; first contact with VV 304A and VV 304B; penetration with Mayall’s Object; out the other side with ESO 77-14; wrap around with VV 705; and merge with The Owl. We end with another simulation. This time it’s the collision between Andromeda and the Milky Way.

The Hubble Space Telescope has been revealing the secrets of the universe for over 30 years, but it turns out Hubble has some secrets of its own! The question is: Hubble has helped confirm that the Milky Way will merge with which nearby galaxy? You might be surprised! See if you know the trivia question before the answer comes up on the screen!

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Have you ever wondered how astronomers know how far away things are? It turns out the the method they use to determine an astronomical object's distance, depends on what it is!

Cosmographers recently revealed a massive wall of galaxies lurking shockingly close by. But why was it hidden from our view for so long? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Cosmographers’ goal is to map out the observable universe, and from their findings we can not only learn more about the structures that make up everything we can see, we also gain insight into the things we cannot see. The universe is full of massive structures hidden from our view, like the area of the sky above the South Pole that has been dubbed the “Zone of Avoidance,” in our very own Milky Way. Some cosmographers pulled out some clever tricks to peer into the Zone of Avoidance. Using a catalog of the motions and distances of 18,000 galaxies called Cosmicflows-3, the scientists noticed that some galaxies were moving faster or slower than expected, and seemed to be drawn to something in the middle, something hidden in the Zone of Avoidance. Computer models revealed a wall made up of thousands of galaxies at least 600 million light-years deep and 1.4 billion light-years across, forming a bow shape over the southern hemisphere’s sky.

As astronomers, one thing we feel like we understand is the shapes of galaxies. But then sometimes something like NGC 474 comes along and crushes those dreams. Luckily we can use the weird mess around NGC 474 as a "whodunnit" to figure out the history of this weird and wonderful galaxy, one that seems to include "galactic cannibalism"... #spaceisweird #weirdisgood #astrophysics Arp (1966) - http://articles.adsabs.harvard.edu/pdf/1966ApJS...14....1A Interactive version of Arp (1966) - Atlas of Peculiar Galaxies - https://ned.ipac.caltech.edu/level5/Arp/paper.pdf Cooper et al.
