The XRISM science team, including members of Nagoya University, has explained how galaxy clusters maintain their heat despite emitting X-rays, which typically have a cooling effect on the hot gas. By observation of the Centaurus cluster of galaxies, the XRISM team discovered the existence of a fast-moving, high-temperature gas flowContinue Reading
Researchers at Nagoya University in Japan have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud (SMC), are moving in opposing directions along two distinct axes. They found that stars closer to Earth move towards the northeast, while more distant stars move southwest. This newly discoveredContinue Reading
Astronomers have discovered nearly 100 examples of massive black holes shredding and devouring stars, almost all of them where you’d expect to find massive black holes: in the star-dense cores of massive galaxies. University of California, Berkeley, astronomers have now discovered the first instance of a massive black hole tearingContinue Reading
Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our understanding of how barred spiral galaxies, like our own Milky Way Galaxy, grow and evolve. Some spiral galaxies, including theContinue Reading
