PhD student discovers 140 new galaxies


Tom Sedgwick, PhD student at the Astrophysics Research Institute (ARI), has with a team of ARI astronomers discovered 140 new and previously unknown galaxies. His findings due to be published in April’s edition of the prestigious journal Monthly Notices of the Royal Astronomical Society. These previously unknown galaxies were found whilst searching for exploding stars, known as supernovae. Supernovae are the violent ends to the lives of the most massive stars. When these stars stop burning their nuclear fuel, they quickly become unstable and their cores collapse, giving rise to some of the…

Public Lecture: Clusters of Galaxies: Light in the dark spaces


Thursday 4th April 2019 at 6:30PM Central Teaching Hub, Liverpool University The 2019 John Porter Memorial Lecture given by Prof Chris Collins Understanding the evolution of mass at the centres of clusters of galaxies is essential if we are to be confident that we can explain structure in the wider universe. However, current telescopes and surveys find it difficult to measure the faint light between the galaxies - the Intra-Cluster Light or ICL - even though in total this can be more significant than the more concentrated light of the central galaxy. This talk will look at current… Read the Full Article

Our study suggests the elusive ‘neutrino’ could make up a significant part of dark matter


Physicists trying to understand the fundamental structure of nature rely on consistent theoretical frameworks that can explain what we see and simultaneously make predictions that we can test. On the smallest scale of elementary particles, the standard model of particle physics provides the basis of our understanding. On the scale of the cosmos, much of our understanding is based on “standard model of cosmology”. Informed by Einstein’s theory of general relativity, it posits that the most of the mass and energy in the universe is made up of mysterious, invisible substances known as dark… Read the Full Article

Dance of galaxies challenges current thinking on cosmology


Scientists have a pretty good picture of how the universe formed and evolved – and how it is structured today. This knowledge all fits together nicely as a “standard cosmological model”, which has been able to successfully predict and describe many observational data in the universe. But now and then scientists discover something that threatens to tear down this valuable framework. New research, published in Science, has done just that. The paper reports that a number of “satellite dwarf galaxies” – small galaxies orbiting around the much larger galaxy, Centaurus A – are rotating in… Read the Full Article

Study of distant galaxies challenges our understanding of how stars form


The most massive galaxies in our neighbourhood formed their stars billions of years ago, early in the history of the universe. At the present day, they produce very few new stars. Astronomers have long believed that is because they contain very little gas – a key ingredient necessary to produce stars. But our new study, published in Nature Astronomy, is now challenging this long held view. Read the Full Article

EU Horizon 2020 funding to uncover the ‘dark side’ of the Universe


We owe our very existence to dark matter. Galaxies as we know them, stars, planets, and people would not exist without its presence. Yet we still have very little understanding of its nature and origin. Equally mysterious is the so-called 'dark energy', which is believed to be an exotic fluid that fills empty space and is thought to be driving the recently-discovered accelerating expansion rate of the Universe. What is the physical origin of dark energy and how does it evolve with time? The answer to these questions rule the fate of our Universe. Liverpool John Moores University’s … Read the Full Article

Gamma-ray burst captured in unprecedented detail


Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail. Using a wide array of ground- and space-based telescope observations, an international team including Liverpool John Moores University and led by University of Maryland constructed one of the most detailed descriptions of a gamma-ray burst to date. The event, named GRB160625B, revealed key details about the initial “prompt” phase of gamma-ray bursts and… Read the Full Article

Could cold spot in the sky be a bruise from a collision with a parallel universe?


Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky. In 2015, they came close to figuring it out as a study showed it to be a “supervoid” in which the density of galaxies is much lower than it is in the rest of the universe. However, other studies haven’t managed to replicate the result. Now new research led by Durham University, submitted for publication in the Monthly Notices of the Royal Astronomical Society, suggests the supervoid theory doesn’t hold up. Intriguingly, that leaves open a pretty wild possibility – the cold spot… Read the Full Article

LJMU astronomer helps uncover new object in famous galaxy


Pointing the Very Large Array (VLA) radio telescope in New Mexico at a famous galaxy for the first time in two decades, a team of astronomers from the Astrophysics Research Institute at Liverpool John Moores University and the National Radio Astronomy Observatory got a big surprise, finding that a bright new object had appeared near the galaxy's core. The object, the scientists concluded, is either a very rare type of supernova explosion or, more likely, an outburst from a second supermassive black hole closely orbiting the galaxy's primary, central supermassive black hole. All large… Read the Full Article

Shooting for the stars: capturing the beauty of science through astrophotography


When thinking about the types of photographs that capture the beauty of science, a stunning landscape or an animal in its natural habitat might come to mind. But when it comes to images from telescopes, we might not immediately consider these as anything more than the collection of scientific data. Beyond their significance in helping us to discover more about our universe, the images of galaxies, planets and stars are also appreciated purely for aesthetic reasons. For many amateur and professional astrophotographers capturing the shapes and colours of the universe is just as important as… Read the Full Article
