    • Class II 6.7 GHz methanol maser association with young massive cores revealed by ALMA 

      Chibueze, James O.; Csengeri, Timea; Tatematsu, Ken'ichi; Hasegawa, Tetsuo; Iguchi, Satoru (IOP, 2017)
      We explored the implication of the association (or lack of it) of 6.7 GHz class II methanol (CH3OH) masers with massive dense cores (MDCs) detected (within a sample of ATLASGAL selected infrared quiet massive clumps) at ...
    • Detection of variable VHE γ-ray emission from the extra-galactic γ-ray binary LMC P3 

      Abdalla, H.; Barnard, M.; Böttcher, M.; Garrigoux, T.; Ivascenko, A.; Krüger, P.P.; Ndiyavala, H.; Pekeur, N.W.; Seyffert, A.S.; Spanier, F.; Sushch, I.; Van der Walt, D.J.; Van Rensburg, C.; Venter, C.; Wadiasingh, Z.; Zacharias, M.; H.E.S.S. Collaboration (EDP Sciences, 2018)
      Context. Recently, the high-energy (HE, 0.1–100 GeV) γ-ray emission from the object LMC P3 in the Large Magellanic Cloud (LMC) has been discovered to be modulated with a 10.3-day period, making it the first extra-galactic ...
    • Extended VHE γ-ray emission towards SGR1806-20, LBV 1806-20, and stellar cluster Cl 1806-20 

      Abdalla, H.; Barnard, M.; Böttcher, M.; Davids, I.D.; Garrigoux, T.; Ivascenko, A.; Krüger, P.P.; Pekeur, N.W.; Seyffert, A.S.; Spanier, F.; Sushch, I.; Van der Walt, D.J.; Venter, C.; Wadiasingh, Z.; H.E.S.S. Collaboration (EDP Sciences, 2018)
      Using the High Energy Spectroscopic System (H.E.S.S.) telescopes we have discovered a steady and extended very high-energy (VHE) γ-ray source towards the luminous blue variable candidate LBV 1806−20, massive stellar cluster ...
    • The orbit of the gamma-ray binary 1FGL J1018.6- 5856 

      Monageng, I.M.; Böttcher, M.; McBride, V.A.; Townsend, L.J.; Kniazev, A.Y. (IOP Publishing, 2017)
      Gamma-ray binaries are a small subclass of the high mass X-ray binary population that exhibit emission across the whole electromagnetic spectrum. We present the radial velocities of 1FGL J1018.6−5856 based on the observations ...
