How chemistry influences cloud structure, star formation, and the IMF
S. Hocuk, S. Cazaux, M. Spaans +1
In the earliest phases of star-forming clouds, stable molecular species, such as CO, are important coolants in the gas phase. Depletion of these molecules on dust surfaces affects…
Disentangling the excitation conditions of the dense gas in M17 SW
J. P. Pérez-Beaupuits, R. Güsten, M. Spaans +7
We probe the chemical and energetic conditions in dense gas created by radiative feedback through observations of multiple CO, HCN and HCO transitions toward the dense core of…
Exploring the molecular chemistry and excitation in obscured luminous infrared galaxies: An ALMA mm-wave spectral scan of NGC 4418
F. Costagliola, K. Sakamoto, S. Muller +7
We obtained an ALMA Cycle 0 spectral scan of the dusty LIRG NGC 4418, spanning a total of 70.7 GHz in bands 3, 6, and 7. We use a combined local thermal equilibrium (LTE) and non-L…
The SCUBA-2 Cosmology Legacy Survey: ALMA resolves the bright-end of the sub-millimeter number counts
James Simpson, Ian Smail, Mark Swinbank +20
We present high-resolution 870-um ALMA continuum maps of 30 bright sub-millimeter sources in the UKIDSS UDS field. These sources are selected from deep, 1-square degrees 850-um map…
H2 formation on PAHs in photodissociation regions: a high-temperature pathway to molecular hydrogen
Leon Boschman, Stéphanie Cazaux, Marco Spaans +2
Molecular hydrogen is the most abundant molecule in the Universe. It is thought that a large portion of H2 forms by association of hydrogen atoms to polycyclic aromatic hydrocarbon…
Probing highly obscured, self-absorbed galaxy nuclei with vibrationally excited HCN
S. Aalto, S. Martin F. Costagliola, E. Gonzalez-Alfonso +16
We present high resolution (0."4) IRAM PdBI and ALMA mm and submm observations of the (ultra) luminous infrared galaxies ((U)LIRGs) IRAS17208-0014, Arp220, IC860 and Zw049.057 that…
The Herschel Comprehensive (U)LIRG Emission Survey (HerCULES): CO Ladders, fine structure lines, and neutral gas cooling
M. J. F. Rosenberg, P. P. van der Werf, S. Aalto +27
(Ultra) Luminous Infrared Galaxies ((U)LIRGs) are objects characterized by their extreme infrared (8-1000 m) luminosities (L and L…
