At the American Astronomical Society meeting the results of the study of galaxies NGC 1448 and IC 3639 were presented showing how they led to the identification of supermassive black holes at their centers. A team of researchers used NASA’s NuSTAR Space Telescope to detect the high energy X-ray emission from them and see beyond the dust and gas that hid those areas.

An article published in the journal “Astronomy & Astrophysics” describes the most detailed view of the molecular cloud called Orion A, one of the two giant molecular clouds in the Orion molecular cloud complex. A team of researchers created it by putting together infrared images obtained from the VISION (Vienna Survey in Orion) survey with ESO’s VISTA telescope revealing many young stars and other objects normally hidden within dust clouds.

Three articles accepted for publication in the journal “Astronomy and Astrophysics” describe as many research on star systems in formation. The research were conducted by different teams of astronomers but have in common the use of the SPHERE instrument mounted on ESO’s VLT (Very Large Telescope), which revealed details never seen before of protoplanetary discs around the young stars RX J1615, HD 97048 and HD 135344B.

An article accepted for publication in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the large columnar structures in the Carina Nebula. A team led by Anna McLeod, a PhD student at ESO, used the MUSE instrument installed on ESO’s VLT (Very Large Telescope) to examine these structures that have been nicknamed “pillars of destruction” for certain similarities with the “Pillars of Creation” photographed by the Hubble space telescope.

An article to be published in “The Astrophysical Journal” describes an investigation into the glowing gas clouds around distant quasars. An international team of astronomers led by a group at the ETH (Swiss Federal Institute of Technology) in Zurich, Switzerland, used the MUSE instrument mounted on ESO’s Very Large Telescope (VLT) to look at very distant galaxies that are active, of the type called quasar, and discovered that the gas halos that surround them are more common than expected.
