An article published in “The Astrophyisical Journal” describes the discovery of the first gamma-ray binary found outside the Milky Way, called LMC P3. A team of researchers led by Robin Corbet at NASA’s Goddard Space Flight Center used the Fermi space telescope to discover this couple in the Large Magellanic Cloud formed by a giant blue star and a companion that might be a neutron star or a black hole that are interacting producing cyclic gamma-ray emission.

A series of articles to be published in “Astrophysical Journal” and “Monthly Notices of the Royal Astronomical Society” describe different parts of a research based on the observation of the Hubble Space Telescope’s Ultra Deep Field (HUDF) using the radio telescope ALMA. These observations show that the rate of star formation in young galaxies is closely related to their total mass in stars.

Two articles, one published in “The Astrophysical Journal Letters” and one published in the journal “Monthly Notices of the Royal Astronomical Society”, describe as many research on the supernova remnants known as RCW103. At its center a neutron star formed called 1E 161348-5055 – or simply 1E 1613 – that has been puzzling astronomers for decades for its abnormal behavior. Now two teams independently offered the same explanation: the neutron star has the characteristics of a magnetar.
