    • Adaptive optics observations of the T10 ultracool dwarf UGPS J072227.51-054031.2 

      Bouy, H.; Girard, J.H.V.; Martin, E.L.; Huelamo, N.; Lucas, P.W. (2011)
      Context: With a spectral type of T10, UGPS J072227.51-054031.2 is one of the coolest objects known to date in the solar neighborhood. Aims: Multiple systems are relatively common among early and mid-T dwarfs. We search for ...

    • Faceting for direction-dependent spectral deconvolution 

      Tasse, C.; Hugo, B.; Mirmont, M.; Smirnov, O.; Atemkeng, M.; Bester, L.; Bonnassieux, E.; Hardcastle, M. J.; Lakhoo, R.; Girard, J.H.V.; Makhathini, S.; Perkins, S.; Shimwell, Timothy W. (2018-03-01)
      The new generation of radio interferometers is characterized by high sensitivity, wide fields of view and large fractional bandwidth. To synthesize the deepest images enabled by the high dynamic range of these instruments ...
