    • An H2Co 6 cm maser pinpointing a possible circumstellar torus in IRAS 18566+0408 
      Araya, E.; Hofner, P.; Sewixo, M.; Goss, W. M.; Linz, H.; Kurtz, S.; Olmi, L.; Churchwell, E.; Rodríguez, L. F.; Garay Brignardello, Guido (UNIV CHICAGO PRESS, 2007-11-10)
      We report observations of 6 cm, 3.6 cm, 1.3 cm, and 7 mm radio continuum, conducted with the Very Large Array, toward IRAS 18566+0408, one of the few sources known to harbor H(2)CO6 cm maser emission. Our observations ...
    • IZI: Inferring the gas phase metallicity (z) and ionization parameter (q) of ionized nebulae using bayesian ... 
      Blanc Mendiberri, Guillermo (The American Astronomical Society, 2015-01-10)
      We present a new method for inferring the metallicity (Z) and ionization parameter (q) of H ii regions and star-forming galaxies using strong nebular emission lines (SELs). We use Bayesian inference to derive the joint and ...
    • Low-velocity shocks traced by extended sio emission along the w43 ridges: witnessing the formation of young ... 
      Nguyen-Luong, Q.; Motte, F.; Carlhoff, P.; Louvet, F.; Lesaffre, P.; Schilke, P.; Hill, T.; Hennemann, M.; Gusdorf, A.; Didelon, P.; Schneider, N.; Bontemps, S.; Duarte Cabral, A.; Menten, K. M.; Martin, P. G.; Wyrowski, F.; Bendo, G.; Roussel, H.; Bernard, J. P.; Bronfman Aguiló, Leonardo; Henning, Thomas; Kramer, C.; Heitsch, F. (The American Astronomical Society, 2013-10-01)
      The formation of high-mass stars is tightly linked to that of their parental clouds. Here, we focus on the high-density parts of W43, a molecular cloud undergoing an efficient event of star formation. Using a column density ...
