A magnetar is a type of neutron star with an extremely powerful magnetic field (~109 to 1011 T, ~1013 to 1015 G). The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays.
Robert C. Duncan (Jr.) is an American astrophysicist now retired from the University of Texas at Austin.
Anomalous X-ray pulsars (AXPs) are an observational manifestation of magnetars—young, isolated, highly magnetized neutron stars. These energetic X-ray pulsars are characterized by slow rotation periods of ~2–12 seconds and large magnetic fields of ~1013–1015 gauss (1 to 100 gigateslas). As of 2017, there were 12 confirmed and 2 candidate AXPs known. The identification of AXPs with magnetars was motivated by their similarity to soft gamma repeaters.
The Dannie Heineman Prize for Astrophysics is jointly awarded each year by the American Astronomical Society and American Institute of Physics for outstanding work in astrophysics. It is funded by the Heineman Foundation in honour of Dannie Heineman.
The Bruno Rossi Prize is awarded annually by the High Energy Astrophysics division of the American Astronomical Society "for a significant contribution to High Energy Astrophysics, with particular emphasis on recent, original work". Named after astrophysicist Bruno Rossi, the prize is awarded with a certificate and a gift of USD $500, and was first awarded in 1985 to William R. Forman and Christine Jones Forman "for pioneering work in the study of X-ray emission from early type galaxies". It has been awarded 40 times. In 2010, the prize was awarded to William B. Atwood, Peter Michelson and the Fermi Gamma-ray Space Telescope team "for enabling, through the development of the Large Area Telescope, new insights into neutron stars, supernova remnants, cosmic rays, binary systems, active galactic nuclei, and gamma-ray bursts". In 2013, the prize was awarded to Roger W. Romani of Leland Stanford Junior University and Alice Harding of Goddard Space Flight Center for their work in developing the theoretical framework underpinning the many exciting pulsar results from Fermi Gamma-ray Space Telescope.

The Hellenic Astronomical Society (Hel.A.S.), in Greek Ελληνική Αστρονομική Εταιρεία (ΕΛ.ΑΣ.ΕΤ.), is a scientific non profit society of professional astronomers in Greece. Its formal headquarters are at the Dept. of Physics of the University of Athens. The main goal of the Society is to advance the research in astronomy, astrophysics and space physics, as well as to support all educational astronomical activities. As is typical for scientific societies it consists of ordinary members, who have a PhD degree in astrophysics and closely related fields, as well as junior and associate members.
