    • From downtown to the outskirts: A radio survey of the Orion Nebula Cluster 

      Vargas-González, Jaime; Forbrich, Jan; Dzib, Sergio A.; Bally, John (2021-09-01)
      We present a newly enlarged census of the compact radio population towards the Orion Nebula Cluster (ONC) using high-sensitivity continuum maps (3-10 μ Jy beam-1) from a total of ∼30-h centimetre-wavelength observations ...

    • Non-thermal radio continuum emission from young nearby stars 

      Launhardt, R.; Loinard, Laurent; Dzib, Sergio A.; Forbrich, J.; Bower, G. C.; Henning, Th K.; Mioduszewski, A. J.; Reffert, S. (2022-05-23)
      Young and magnetically active low-mass stars often exhibit non-thermal coronal radio emission due to the gyration of electrons in their magnetized chromospheres. This emission is easily detectable at centimeter wavelengths ...

      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 ...

    • A VLBA Survey of radio stars in the Orion Nebula Cluster: I. The nonthermal radio population 

      Forbrich, Jan; Dzib, Sergio A.; Reid, Mark J.; Menten, Karl M. (2021-01-04)
      We present first results of a four-epoch VLBA survey for nonthermal emission toward all 556 compact radio sources previously identified in a deep VLA survey of the Orion Nebula Cluster (ONC). We identify VLBA counterparts ...

    • A VLBA Survey of radio stars in the Orion Nebula Cluster: II. Astrometry 

      Dzib, Sergio A.; Forbrich, Jan; Reid, Mark J.; Menten, Karl M. (2021-01-04)
      From Very Long Baseline Array (VLBA) observations we previously identified a population of 123 young stellar systems with nonthermal radio emission toward the core of the Orion Nebula Cluster (ONC). We find optical sources ...
