    • An ALMA survey of submillimeter galaxies in the extended chandra deep field south : Near-infrared morphologies and stellar sizes 

      Chen, Chian Chou; Smail, Ian; Swinbank, A.M.; Simpson, J. M.; Ma, Cheng Jiun; Alexander, D.M.; Biggs, A. D.; Brandt, W.N.; Chapman, S.C.; Coppin, Kristen; Danielson, A. L. R.; Dannerbauer, H.; Edge, A. C.; Greve, T.R.; Ivison, R. J.; Karim, A.; Menten, Karl M.; Schinnerer, E.; Walter, F.; Wardlow, J. L.; Weiß, A.; Van Der Werf, P. P. (2015-02-01)
      We analyze Hubble Space Telescope WFC3/H160-band observations of a sample of 48 Atacama Large Millimeter/submillimeter Array detected submillimeter galaxies (SMGs) in the Extended Chandra Deep Field South field, to study ...
    • Extreme radio flares and associated X-ray variability from young stellar objects in the Orion Nebula Cluster 

      Forbrich, Jan; Reid, Mark J.; Menten, Karl M.; Rivilla, Victor M.; Wolk, Scott J.; Rau, Urvashi; Chandler, Claire J. (2017-07-27)
      Young stellar objects are known to exhibit strong radio variability on timescales of weeks to months, and a few reports have documented extreme radio flares with at least an order of magnitude change in flux density on ...
    • The Population of Compact Radio Sources in the Orion Nebula Cluster 

      Forbrich, Jan; Rivilla, Victor M.; Menten, Karl M.; Reid, Mark J.; Chandler, Claire J.; Rau, Urvashi; Bhatnagar, Sanjay; Wolk, Scott J.; Meingast, Stefan (2016-05-10)
      We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30h single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1 GHz ...
    • 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 ...
    • 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 ...
