    • An ALMA study of the Orion Integral Filament : I. Evidence for narrow fibers in a massive cloud 

      Hacar, A.; Tafalla, M.; Forbrich, J.; Alves, J.; Meingast, S.; Grossschedl, J.; Teixeira, P. S. (2018-03-07)
      Aim. We have investigated the gas organization within the paradigmatic Integral Shape Filament (ISF) in Orion in order to decipher whether or not all filaments are bundles of fibers. Methods. We combined two new ALMA Cycle ...

    • APOGEE strings: a fossil record of the gas kinematic structure 

      Hacar, A.; Alves, J.; Forbrich, J.; Meingast, S.; Kubiak, K.; Grossschedl, J. (2016-05-01)
      We compare APOGEE radial velocities (RVs) of young stars in the Orion A cloud with CO line gas emission and find a correlation between the two at large-scales, in agreement with previous studies. However, at smaller scales ...

    • Orion revisited III. The Orion Belt population 

      Kubiak, K.; Alves, J.; Bouy, H.; Sarro, L. M.; Ascenso, J.; Burkert, A.; Forbrich, J.; Großschedl, J.; Hacar, A.; Hasenberger, B.; Lombardi, M.; Meingast, S.; Köhler, R.; Teixeira, P. S. (2017-02-13)
      This paper continues our study of the foreground population to the Orion molecular clouds. The goal is to characterize the foreground population north of NGC 1981 and to investigate the star formation history in the large ...

    • A systematic survey of millimetre-wavelength flaring variability of Young Stellar Objects in the Orion Nebula Cluster 

      Vargas-González, J.; Forbrich, J.; Rivilla, V. M.; Menten, K. M.; Güdel, M.; Hacar, A. (2023-03-29)
      High-energy processes are ubiquitous even in the earliest stages of protostellar evolution. Motivated by the results of our systematic search for intense centimeter radio flares in Young Stellar Objects (YSOs) and by rare ...
