    • A population of hypercompact HII regions identified from young HII regions 

      Yang, Aiyuan; Urquhart, James; Thompson, Mark; Menten, Karl; Wyrowski, Friedrich; Brunthaler, Andreas; Tian, Wenwu; Rugel, Michael; Yang, Xiaolong; Yao, Su; Mutale, Mubela (2021-01-22)
      Context. The derived physical parameters for young H II regions are normally determined assuming the emission region to be optically thin. However, this assumption is unlikely to hold for young H II regions such as ...

    • Tomography of Galactic star-forming regions and spiral arms with the Square Kilometer Array 

      Loinard, Laurent; Thompson, Mark; Hoare, Melvin; Langevelde, Huib Jan van; Ellingsen, Simon; Brunthaler, Andreas; Forbrich, Jan; Rygl, Kazi L. J.; Rodriguez, Luis F.; Mioduszewski, Amy J.; Torres-Lopez, Rosa M.; Dzib, Sergio A.; Ortiz-Leon, Gisela N.; Bourke, Tyler L.; Green, James A. (Proceedings of Science (PoS), 2014-12-19)
      Very Long Baseline Interferometry (VLBI) at radio wavelengths can provide astrometry accurate to 10 micro-arcseconds or better (i.e. better than the target GAIA accuracy) without being limited by dust obscuration. This ...
