      We present the results of a deep study of the neutron star (NS) population in the globular cluster M28 (NGC 6626), using the full 330 ks 2002–2015 ACIS data set from the Chandra X-ray Observatory and coordinated radio ...

    • Solving the Multimessenger Puzzle of the AGN-starburst Composite Galaxy NGC 1068 

      Eichmann, Björn; Oikonomou, Foteini; Salvatore, Silvia; Dettmar, Ralf-Jürgen; Tjus, Julia Becker (Peer reviewed; Journal article, 2022)
      Multiwavelength observations indicate that some starburst galaxies show a dominant nonthermal contribution from their central region. These active galactic nuclei (AGN)-starburst composites are of special interest, as both ...
