    • 3D shape of Orion A from Gaia DR2 

      Grossschedl, Josefa E.; Alves, Joao; Meingast, Stefan; Ackerl, Christine; Ascenso, Joana; Bouy, Herve; Burkert, Andreas; Forbrich, Jan; Fuernkranz, Verena; Goodman, Alyssa; Hacar, Alvaro; Herbst-Kiss, Gabor; Lada, Charles J.; Larreina, Irati; Leschinski, Kieran; Lombardi, Marco; Moitinho, Andre; Mortimer, Daniel; Zari, Eleonora (2018-11-14)
      We use the Gaia DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation. We find that Orion A is not the fairly straight ...
    • The HP2 Survey - IV. The Pipe nebula : Effective dust temperatures in dense cores 

      Hasenberger, Birgit; Lombardi, Marco; Alves, João; Forbrich, Jan; Hacar, Alvaro; Lada, Charles J. (2018-07-16)
      Multi-wavelength observations in the sub-mm regime provide information on the distribution of both the dust column density and the effective dust temperature in molecular clouds. In this study, we created high-resolution ...
    • Some like it cold: molecular emission and effective dust temperatures of dense cores in the Pipe Nebula 

      Forbrich, Jan; Öberg, Karin; Lada, Charles J.; Lombardi, Marco; Hacar, Alvaro; Alves, João; Rathborne, Jill M. (2014-08-08)
      Aims. The Pipe Nebula is characterized by a low star-formation rate and is therefore an ideal environment to explore how initial conditions, including core characteristics, affect star-formation efficiencies. Methods. In ...
    • VISION - Vienna survey in Orion I. VISTA Orion A Survey 

      Meingast, Stefan; Alves, João; Mardones, Diego; Teixeira, Paula; Lombardi, Marco; Großschedl, Josefa; Ascenso, Joana; Bouy, Herve; Forbrich, Jan; Goodman, Alyssa; Hacar, Alvaro; Hasenberger, Birgit; Kainulainen, Jouni; Kubiak, Karolina; Lada, Charles; Lada, Elizabeth; Moitinho, André; Petr-Gotzens, Monika; Rodrigues, Lara; Román-Zúñiga, Carlos G. (2016-03-07)
      Orion A hosts the nearest massive star factory, thus offering a unique opportunity to resolve the processes connected with the formation of both low- and high-mass stars. Here we present the most detailed and sensitive ...
