New study uses self-interacting dark matter to solve the final ... - MSNIn a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter. When two galaxies merge ...
From galaxies with no dark matter to ones with hundreds of times more dark matter than normal, ... when galaxies interact or merge, and when galaxies speed through matter-rich regions, ...
If the idea of dark matter is correct, some of the dwarfs, particularly in the vicinity of post-merger galaxies, should be dark matter-free. ESA/Hubble and NASA.
If dark-matter-poor galaxies were a normal part of the Universe's evolution, then we probably should have seen the models produce one. But there was no report of one showing up. So, we were left ...
Scientists have yet to directly measure dark matter, but it's thought to make up around 27 percent of the universe (compared to just 5 percent made up of known matter like stars and galaxies ...
Dark matter could act as a cosmic matchmaker between dark matter and merging supermassive black holes, ... Alonso-Álvarez explained that, when galaxies first merge, ...
“These are very normal, nearby elliptical galaxies that they studied, and if those galaxies don’t have dark matter it calls into question the whole theory of cold dark matter,” said Joel ...
Dark energy camera captures galaxies in lopsided tug of war, a prelude to merger. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2023 / 07 / 230726113043.htm ...
A new study suggests that the orderly arrangement of the Milky Way's satellite galaxies may be a coincidence; if the research holds up, it could undermine our understanding of dark matter.
These models are known, appropriately enough, as self-interacting dark matter. ... Supermassive black holes are thought to merge as the last stage in the merger of two galaxies.
Crude maps of its distribution indicate dark matter forms a sort of cosmic web, where galaxies large and small are gravitationally glued to filaments and sheets of dark matter. “We have this web ...
Studying dark matter is complicated. In reality, the best way to think about the phenomenon is as transparent matter. We can't seem to see it, and it doesn't interact with light, so essentially ...
