    • MHD-shock structures of astrospheres: λ Cephei-like astrospheres 

      Scherer, K.; Ferreira, S.E.S.; Baalmann, L.R.; Fichtner, H.; Kleimann, J. (Oxford Univ Press, 2020)
      The interpretation of recent observations of bow shocks around O-stars and the creation of corresponding models require a detailed understanding of the associated (magneto-)hydrodynamic structures. We base our study on 3D ...
    • New hard-TeV extreme blazars detected with the MAGIC telescopes 

      Acciari, V.A.; Arcaro, C.; Ansoldi, S.; Antonelli, L.A.; Arbet Engels, A. (IOP, 2020)
      Extreme high-frequency-peaked BL Lac objects (EHBLs) are blazars that exhibit extremely energetic synchrotron emission. They also feature nonthermal gamma-ray emission whose peak lies in the very high-energy (VHE, E > 100 ...
    • A NICER view of spectral and profile evolution for three x-ray-emitting millisecond pulsars 

      Rowan, Dominick M.; Venter, Christo; Ghazi, Zaynab; Lugo, Lauren; Spano, Elizabeth (IOP, 2020)
      We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821−24, and J0218+4232. We fit Gaussians and ...
