This self-interacting dark matter may trigger a dramatic collapse inside dark matter halos, heating and densifying their cores in surprising ways. Until now, this crucial middle ground of behavior was nearly impossible to model accurately. The new code makes these simulations faster, more precise, and accessible enough to run on a laptop.

Scientists are developing detectors so sensitive they can spot particle interactions that might occur once in years or even decades. These experiments aim to uncover what shapes galaxies and fuels cosmic expansion. Cracking this mystery could transform our understanding of the laws of nature.

A University of Tokyo researcher analyzing new data from NASA’s Fermi Gamma-ray Space Telescope has detected a halo of high-energy gamma rays that closely matches what theories predict should be released when dark matter particles collide and annihilate. The energy levels, intensity patterns, and shape of this glow align strikingly well with long-standing models of weakly interacting massive particles, making it one of the most compelling leads yet in the hunt for the universe’s invisible mass.

By comparing how galaxies move through cosmic gravity wells to the depth of those wells, researchers found that dark matter appears to behave much like ordinary matter, obeying familiar physical laws. Still, the possibility of a hidden fifth force lingers, one that must be very weak to have evaded detection so far.

By rethinking gravity and cosmic timelines, it could rewrite our understanding of space and time itself.

Using a network-like model of particle connections, they argue that light could be influenced indirectly by Dark Matter through intermediaries. Detecting these tints could unlock a whole new way to explore the hidden 85% of the Universe. The finding could reshape how telescopes search for cosmic mysteries.

These colossal, luminous hydrogen-and-helium spheres may explain both the existence of unexpectedly bright early galaxies and the origin of the first supermassive black holes.

Its results not only narrow the possibilities for dark matter but also open exciting paths toward other rare physics discoveries.

Unlike axions or WIMPs, these particles carry electric charge but remain undetectable due to their scarcity. With detectors like JUNO and DUNE, researchers now have a chance to spot their unique signal, a breakthrough that could link particle physics with gravity.

These tiny but brilliant objects, discovered by the James Webb Space Telescope, appear far too compact and bright to fit existing models of galaxy and black hole formation. A new study suggests they may have formed within rare dark matter halos that spin unusually slowly, creating conditions that squeeze matter into incredibly dense structures. If true, these galaxies could provide vital clues about how the first black holes and galaxies came into being.

These elusive "orphan" galaxies have likely been stripped of their dark matter by the Milky Way’s gravity and hidden from view. If spotted by next-gen telescopes like the Rubin Observatory’s LSST, they could solidify our understanding of the Universe’s structure and deliver a stunning validation of the Lambda Cold Dark Matter model.

Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark matter halos exist. An Diego astrophysicist has calculated the mass below which halos fail to form.

Fri, 13 Sep 2024 18:35:04 EDT https://www.sciencedaily.com/releases/2024/09/240913183504.htm https://www.sciencedaily.com/releases/2024/08/240828155009.htm Supermassive black holes typically take billions of years to form. But the James Webb Space Telescope is finding them not that long after the Big Bang -- before they should have had time to form. Astrophysicists have discovered that if dark matter decays, the photons it emits keep the hydrogen gas hot enough for gravity to gather it into giant clouds and eventually condense it into a supermassive black hole. In addition to explaining the existence of very early supermassive black holes, the finding lends support for the existence of a kind of dark matter capable of decaying into particles such as photons.

The team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the relationship between a galaxy's size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.

New research shows that rotation curves of galaxies stay flat indefinitely far out, corroborating predictions of modified gravity theory as an alternative to dark matter.

Now a new theoretical research tells how the invisible part of our universe could help us find out, suggesting a primordial genesis, even within a second of the Big Bang.

Mon, 27 Nov 2023 13:23:51 EST https://www.sciencedaily.com/releases/2023/11/231127132351.htm https://www.sciencedaily.com/releases/2023/06/230614220651.htm Researchers reveal a theoretical breakthrough that may explain both the nature of invisible dark matter and the large-scale structure of the universe known as the cosmic web. The result establishes a new link between these two longstanding problems in astronomy, opening new possibilities for understanding the cosmos. The research suggests that the 'clumpiness problem,' which centres on the unexpectedly even distribution of matter on large scales throughout the cosmos, may be a sign that dark matter is composed of hypothetical, ultra-light particles called axions. The implications of proving the existence of hard-to-detect axions extend beyond understanding dark matter and could address fundamental questions about the nature of the universe itself.

Their work resolves an outstanding problem in astrophysics first raised two decades ago: why do models that adopt ultramassive Dark Matter particles fail to correctly predict the observed positions and the brightness of multiple images of the same galaxy created by gravitational lensing?

This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity. A new study challenges this view of the Universe. The results suggest that the dwarf galaxies of Earth's second closest galaxy cluster -- known as the Fornax Cluster -- are free of such dark matter halos.

Missions like the Hubble and James Webb space telescopes would have to patch together hundreds of small images to see these structures around nearby galaxies in full. Roman will do so in a single snapshot. Astronomers will use these observations to explore how galaxies grow and the nature of dark matter.

Its properties, too, remain fairly obscure. Now, a theoretical particle physicist have shown how theories positing the existence a new type of force could help explain dark matter's properties.

This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes formed and grew so quickly. It supports the theory that black holes can grow rapidly within large structures which contain plenty of gas to fuel them.

The team found indications that the number of dark matter halos could be inconsistent with what the simplest cosmological model suggests. This could be a new clue to understanding why the expansion of the universe is accelerating.

In particular, their theory involves dark matter particles which are extremely light -- almost one hundred times lighter than electrons, in stark contrast to many conventional models that involve very heavy dark matter particles instead.

Researchers can now show through simulations how it might look.

Theorists have proposed a different type of dark matter particle, a strongly interacting massive particle or SIMP, that differs from WIMPs in that they interact strongly with one another and hardly at all with normal matter. The dark matter structure of a galaxy pile-up could be evidence for SIMPs.

The sensitivity of the detector -- an underground sentinel awaiting a collision that would confirm a hypothesis - stems from both its size and its 'silence.'
