(Phys.org) —Scientists have many tools for measuring the cosmic structures of the universe, which includes structures such as galaxies, galaxy clusters, and intergalactic gas. Cosmic structures can be observed directly, ...
(Phys.org)—One of the first observations suggesting the existence of an invisible dark matter came in 1933 when astronomer Fritz Zwicky noticed that galaxy clusters were more energetic than they should be, according to ...
(PhysOrg.com) -- Magnetic fields play an important role on scales ranging from the sub-atomic to the cosmic, from particle spins to galaxy clusters. Although scientists know how to create and manipulate magnetic fields, as ...
By analyzing the data from NASA's Chandra X-ray observatory, astronomers from India and South Africa have investigated a massive galaxy cluster known as Abell 2566. They detected sloshing cold fronts in the intracluster medium ...
An international team of astronomers has performed radio observations of a massive galaxy cluster known as ACT-CL J0329.2-2330, which resulted in the detection of a new radio halo in this cluster. The finding was reported ...
Astronomers have discovered a new post-asymptotic giant branch (PAGB) star in a Galactic globular cluster known as ESO 37-1 (or E3 for short) and derived its fundamental parameters. The finding is reported in a research paper ...
Astronomers from the Nanjing University in China and elsewhere have performed high-resolution observations of a distant galaxy cluster known as CL J1001+0220 using the James Webb Space Telescope (JWST). The observational ...
Using the Canada France Hawaii Telescope (CFHT), Chinese astronomers have performed multi-band observations of a merging dwarf galaxy known as VCC 322. Results of the observational campaign, presented March 4 on the preprint ...
Using the Hubble Space Telescope (HST), astronomers have investigated the stellar population of the globular cluster NGC 1835. They detected a remarkably extended horizontal branch in this system. The discovery, reported ...
Using the Magellan Telescopes in Chile, Italian astronomers have observed a giant galaxy cluster known as Abell 2744, dubbed the Pandora's Cluster. Results of the observational campaign, presented in a paper published February ...
