    • Nonthermal Radio Continuum Emission from Young Nearby Stars 

      Launhardt, Ralf; Loinard, Laurent; Dzib, Sergio A.; Forbrich, Jan; Bower, Geoffrey C.; Henning, Thomas K.; Mioduszewski, Amy J.; Reffert, Sabine (2022-05-23)
      Young and magnetically active low-mass stars often exhibit nonthermal coronal radio emission owing to the gyration of electrons in their magnetized chromospheres. This emission is easily detectable at centimeter wavelengths ...

    • Radio Measurements of the stellar proper motions in the core of the Orion Nebula Cluster 

      Dzib, Sergio A.; Loinard, Laurent; Rodríguez, Luis F.; Gómez, Laura; Forbrich, Jan; Menten, Karl M.; Kounkel, Marina A.; Mioduszewski, Amy J.; Hartmann, Lee; Tobin, John J.; Rivera, Juana L. (2017-01-10)
      Using multi-epoch VLA observations, covering a time baseline of 29.1 years, we have measured the proper motions of 88 young stars with compact radio emission in the core of the Orion Nebula Cluster (ONC) and the neighboring ...

    • 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 ...
