An international team of astronomers has performed a multiwavelength study of a galaxy cluster known as ACT-CL J0019.6+0336 (J0019 for short). Results of the research, published November 8 on the arXiv pre-print repository, ...
An international team of astronomers has conducted radio observations of an active galactic nucleus (AGN) known as J1420+1205. Results of this observational campaign suggest that this source is not a blazar like was previously ...
Using the Giant Metrewave Radio Telescope (GMRT), Indian astronomers have conducted radio observations of a galaxy cluster known as Abell 725. Results of this observational campaign deliver important information regarding ...
Using the Giant Metrewave Radio Telescope (GMRT), astronomers from South Africa and Poland have conducted radio observations of a giant radio galaxy (GRG) known as J0133−1302. The observational campaign revealed that the ...
Galaxies—massive collections of gas, dust, and billions of stars and their solar systems—are a fundamental component of our Universe. Understanding how they have formed and evolved over cosmic eras remains one of the ...
