An article accepted for publication in the journal “Physical Review Letters” describes a research on the distribution of matter in the universe made in a way different from usual. An international team of researchers studied cosmic voids as if they were photographic negatives from which they could get information about ordinary matter, dark energy and dark matter.
An article published in “The Astrophysical Journal Letters” describes a research about the dwarf galaxy DDO 68. An international team of researchers led by Francesca Annibali of the National Institute for Astrophysics (INAF), Italy, used the Large Binocular Telescope (LBT) to make observations that allowed to find evidence that even a very small galaxy can capture smaller galaxies.
An article published in “The Astrophysical Journal” describes a research on the so-called Cosmic X-ray Background (CXB). A team of researchers led by Fiona Harrison of Caltech in Pasadena used NASA’s NuSTAR space telescope to distinguish a good part of the X-ray emission coming from supermassive black holes.
An article published in “The Astrophysical Journal” describes a research on the huge halo of gas surrounding the Milky Way. A group of astronomers at the University of Michigan used data from ESA’s XMM-Newton telescope’s archives to discover that the galaxy’s halo spins in the same direction and at a speed comparable with its disk. This discovery may help better understand the formation of galaxies and solar systems within them.
The radio telescope MeerKAT has been activated and the first images of the observations have been released. MeerKAT’s sensitivity was immediately demonstrated because in the observed area 70 galaxies were known but over 1300 have been detected. It’s a great achievement for one of the precursors of the SKA project, the next-generation radio telescope whose activation is scheduled for 2020.
