Does dark matter annihilate quicker in the Milky Way?
Researchers at the Tata Institute of Fundamental Research in Mumbai have proposed a theory that predicts how dark matter may be annihilating much more rapidly in the Milky Way, than in smaller or larger galaxies and the early Universe. (2017-06-23)

The end to a mystery?
Astronomers at the University of St Andrews believe they can (2008-01-31)

Dark matter mystery deepens
Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter holding them together, our galaxy's speedy stars would fly off in all directions. The nature of dark matter is a mystery -- a mystery that a new study has only deepened. (2011-10-17)

Dark matter may be older than the big bang, study suggests
Dark matter, which researchers believe make up about 80% of the universe's mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new Johns Hopkins University study now suggests that dark matter may have existed before the Big Bang. (2019-08-07)

Better defining the signals left by as-yet-undefined dark matter at the LHC
Physicists still don't exactly know what dark matter is. Indeed, they can only see its effect in the form of gravity. Now, the high energy physics community has developed a set of simplified models which retain the elegance of the traditional Effective Field Theories-style models yet provide a better description of the signals of dark matter. These developments are described in a review published in EPJ C. (2016-07-26)

Exploring the secrets of dark matter
Queen's University Professor Wolfgang Rau is among a group of 60 scientists involved in the Cryogenic Dark Matter Search experiment whose latest findings are published in the latest edition of Science magazine.

Waterloo researchers capture first image of a dark matter web that connects galaxies
Researchers at the University of Waterloo have been able to capture the first composite image of a dark matter bridge that connects galaxies together. The composite image, which combines a number of individual images, confirms predictions that galaxies across the universe are tied together through a cosmic web connected by dark matter that has until now remained unobservable. (2017-04-12)

Taking the temperature of dark matter
Warm, cold, just right? Physicists at UC Davis are using gravitational lensing to take the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe. (2020-01-15)

Dark matter guides growth of supermassive black holes
Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and less massive than its home galaxy. A new study of football-shaped collections of stars called elliptical galaxies finds that the invisible hand of dark matter somehow influences black hole growth. (2015-02-18)

New theory on the origin of dark matter
Scientists at Johannes Gutenberg University Mainz in Germany have come up with a new theory on how dark matter may have been formed shortly after the origin of the universe. This new model proposes an alternative to the WIMP paradigm that is the subject of various experiments in current research. (2017-08-08)

Beyond the Standard Model through 'mini spirals'
Statistical analysis of mini-spiral galaxies shows an unexpected interaction between dark matter and ordinary matter. According to the SISSA study recently published in Monthly Notices of the Royal Astronomical Society, where the relationship is obvious and cannot be explained in a trivial way within the context of the Standard Model, these objects may serve as 'portals' to a completely new form of Physics which can explain phenomena like matter and dark energy. (2016-12-15)

New data adds to the hunt for dark matter in the universe
Will dark matter turn out to be Weakly Interacting Massive Particles (WIMPs)? This week, an experiment deep in a mine added new and intriguing information about this theory. The scientist leading the research team -- Juan Collar, the Kavli Institute for Cosmological Physics, University of Chicago -- discusses the latest findings and their implications. (2011-06-08)

Scientists find further evidence for a population of dark matter deficient dwarf galaxies
Researchers from the National Astronomical Observatories of the Chinese Academy of Science (NAOC), Peking University and Tsinghua University have found a special population of dwarf galaxies that could mainly consist baryons within radii of up to tens of thousands of light-years. This contrasts with the normal expectation that such regions should instead be dominated by dark matter. (2019-12-09)

UBC physicists make atoms and dark matter add up
Physicists at the University of British Columbia and TRIUMF have proposed a unified explanation for dark matter and the so-called baryon asymmetry -- the apparent imbalance of matter with positive baryon charge and antimatter with negative baryon charge in the Universe. (2010-11-24)

Galaxy clusters collide; dark matter still a mystery
When galaxy clusters collide, their dark matters pass through each other, with very little interaction. Deepening the mystery, a study by scientists at EPFL and the University of Edinburgh challenges the idea that dark matter is composed of particles. (2015-03-26)

Placing another piece in the dark matter puzzle
A team led by Prof Dmitry Budker has continued their search for dark matter within the framework of the 'Cosmic Axion Spin Precession Experiment' (or 'CASPEr' for short). The CASPEr group conducts their experiments at the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM). CASPEr is an international research program that uses nuclear magnetic resonance techniques to identify and analyze dark matter. (2019-10-25)

How can we use neutrinos to probe dark matter in the sun?
The existence of dark matter particles in the sun's interior seems inevitable, despite dark matter never having been observed (there or elsewhere), despite intensive ongoing searches. Once gravitationally captured by the sun, these particles tend to accumulate in its core. In a paper to be published in the scientific journal Science, Dr. Ilidio Lopes and professor Joseph Silk propose that the presence of dark matter in the sun's interior causes a significant drop in its central temperature. (2010-09-09)

Scientists solve cosmological puzzle
Researchers using supercomputer simulations have exposed a very violent and critical relationship between interstellar gas and dark matter when galaxies are born -- one that has been largely ignored by the current model of how the universe evolved. (2007-11-29)

Dark matter at the heart of our galaxy
The Universe is pervaded by a mysterious form of matter, dubbed dark matter, about five times more abundant than the ordinary matter -- made of atoms -- we are familiar with. Its existence in galaxies was robustly established in the 1970s. Scientists now obtained for the first time a direct observational proof of the presence of dark matter in the innermost part of our Galaxy, the Milky Way. (2015-02-09)

Potential signs of 'interacting' dark matter suggest it is not completely dark after all
Astronomers believe they might have observed the first potential signs of dark matter interacting with a force other than gravity. (2015-04-14)

In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns. Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant universe. (2018-01-16)
