    • An ATCA survey of Sagittarius B2 at 7 mm: chemical complexity meets broad-band interferometry 
      Corby, Joanna; Jones, Paul; Cunningham, María; Menten, Karl; Belloche, Arnaud; Schwab, Frederic; Walsh, Andrew; Balnozan, Egon; Brofman Aguiló, Leonardo; Lo, Nadia; Remijan, Anthony (Royal Astronomical Society, 2015)
      We present a 30–50 GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array with ∼5–10 arcsec resolution. This work releases the survey data and demonstrates the utility of scripts that perform ...
    • ATLASGAL - Kinematic distances and the dense gas mass distribution of the inner Galaxy 
      Wienen, M.; Wyrowski, F.; Menten, K. M.; Urquhart, J. S.; Csengeri, T.; Walmsley, C. M.; Bontemps, S.; Russeil, D.; Bronfman Aguiló, Leonardo; Koribalski, B. S.; Schuller, F. (EDP Sciences, 2015)
      Context. The formation of high mass stars and clusters occurs in giant molecular clouds. Objects in evolved stages of massive star formation such as protostars, hot molecular cores, and ultracompact HII regions have been ...
    • G331.512-0.103: An interstellar laboratory for molecular synthesis. I. the ortho-to-para ratios for CH3OH and CH3CN 
      Mendoza, Edgar; Bronfman Aguiló, Leonardo; Duronea, Nicolas U.; Lepine, Jacques R. D.; Finger Camus, Ricardo; Merello, Manuel; Hervías-Caimapo, Carlos; Gama, Diana R. G.; Reyes, Nicolás; Ake Nyman, Lars (IOP Publishing Ltd, 2018)
      Spectral line surveys reveal rich molecular reservoirs in G331.512-0.103, a compact radio source in the center of an energetic molecular outflow. In this first work, we analyze the physical conditions of the source by means ...
    • Millimeter-wave Line Ratios and Sub-beam Volume Density Distributions 
      Leroy, Adam K.; Usero, Antonio; Schruba, Andreas; Bigiel, Frank; Kruijssen, J. M.Diederik; Kepley, Amanda; Blanc Mendiberri, Guillermo; Bolatto, Alberto D.; Cormier, Diane; Gallagher, Molly; Hughes, Annie; Jiménez Donaire, María J.; Rosolowsky, Erik; Schinnerer, Eva (IOP Publishing, 2017)
      We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam. For observations targeting external galaxies, ...
    • Scaled up low-mass star formation in massive star-forming cores in the G333 giant molecular cloud 
      Wiles, B.; Lo, N.; Redman, M. P.; Cunningham, M. R.; Jones, P. A.; Burton, M. G.; Bronfman Aguiló, Leonardo (Oxford Univ Press, 2016)
      Three bright molecular line sources in G333 have recently been shown to exhibit signatures of infall. We describe amolecular line radiative transfer (RT) modelling process which is required to extract the infall signature ...
    • SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium 
      Schuller, F.; Csengeri, T.; Urquhart, J.S.; Duarte Cabral, A.; Barnes, P.J.; Giannetti, A.; Hernandez, A.K.; Leurini, S.; Mattern, M.; Medina, S. -N.X.; Agurto, C.; Azagra, F.; Anderson, L. D.; Beltrán, M.T.; Beuther, H.; Bontemps, S.; Bronfman Aguiló, Leonardo; Dobbs, C.L.; Dumke, M.; Finger Camus, Ricardo; Ginsburg, A.; González, E.; Henning, Thomas; Kauffmann, J.; Mac Auliffe, F.; Menten, K.M.; Montenegro Montes, F.M.; Moore, T.J.T; Muller, E.; Parra, R.; Pérez Beaupuits, J. -P.; Pettitt, A.; Russeil, D.; Sánchez Monge, A.; Schilke, P.; Schisano, E.; Suri, S.; Testi, L.; Torstensson, K.; Venegas, P.; Wang, K.; Wienen, M.; Wyrowski, F.; Zavagno, A. (EDP Sciences, 2017-05)
      Context. The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. Many large-scale surveys of the Galactic plane have ...
    • The SEDIGISM survey: First data release and overview of the galacti structure 
      Schuller, F.; Urquhart, J. S.; Csengeri, T.; Colombo, D.; Duarte Cabral, A.; Mattern, M.; Ginsburg, A.; Pettitt, A. R.; Wyrowski, F.; Anderson, L.; Azagra, F.; Barnes, P.; Beltran, M.; Beuther, H.; Billington, S.; Bronfman Aguilo, Leonardo Jaime; Cesaroni, R.; Dobbs, C.; Eden, D.; Lee, M. Y.; Medina, S. N. X.; Menten, K. M.; Moore, T.; Montenegro Montes, F. M.; Ragan, S.; Rigby, A.; Riener, M.; Russeil, D.; Schisano, E.; Sánchez Monge, A.; Traficante, A.; Zavagno, A.; Agurto, C.; Bontemps, S.; Finger, R.; Giannetti, A.; González, E.; Hernández, A.

P.; Schilke, P.; Schneider, N.; Suri, S.; Testi, L.; Torstensson, K.; Veena, V. S.; Venegas, P.; Wang, K.; Wienen, M. (Oxford University Press, 2021)
      The SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic InterstellarMedium) survey used the APEX telescope to map 84 deg2 of the Galactic plane between = −60◦ and +31◦ in several molecular transitions, ...
