Fast, Collimated Outflow in the Western Nucleus of Arp 220
Loreto Barcos-Muñoz, Susanne Aalto, Todd A. Thompson +6
We present the first spatially and spectrally resolved image of the molecular outflow in the western nucleus of Arp\,220. The outflow, seen in HCN~(1--0) by ALMA, is compact and co…
Identifying the subtle signatures of feedback from distant AGN using ALMA observations and the EAGLE hydrodynamical simulations
J. Scholtz, D. M. Alexander, C. M. Harrison +10
We present sensitive 870m continuum measurements from our ALMA programmes of 114 X-ray selected AGN in the CDF-S and COSMOS fields. We use these observations in combination with…
An Infrared Study of the Circumstellar Material Associated with the Carbon Star R Sculptoris
Matthew J. Hankins, Terry L. Herter, Matthias Maercker +2
The asymptotic giant branch (AGB) star R Sculptoris (R Scl) is one of the most extensively studied stars on the AGB. R Scl is a carbon star with a massive circumstellar shell ($M_{…
Major impact from a minor merger - The extraordinary hot molecular gas flow in the Eye of the NGC 4194 Medusa galaxy
S. König, S. Aalto, S. Muller +6
Minor mergers are important processes contributing significantly to how galaxies evolve across the age of the Universe. Their impact on supermassive black hole growth and star form…
Deep ALMA photometry of distant X-ray AGN: improvements in star formation rate constraints, and AGN identification
F. Stanley, C. M. Harrison, D. M. Alexander +5
We present the star formation rates (SFRs) of a sample of 109 galaxies with X-ray selected active galactic nuclei (AGN) with moderate to high X-ray luminosities (L(2-8keV)= 10^42-1…
ALMA Observations of the Physical and Chemical Conditions in Centaurus A
Mark McCoy, Jürgen Ott, David S. Meier +13
Centaurus A, with its gas-rich elliptical host galaxy, NGC 5128, is the nearest radio galaxy at a distance of 3.8 Mpc. Its proximity allows us to study the interaction between an a…
Revised Models of Interstellar Nitrogen Isotopic Fractionation
E. S. Wirström, S. B. Charnley
Nitrogen-bearing molecules in cold molecular clouds exhibit a range of isotopic fractionation ratios and these molecules may be the precursors of N enrichments found in come…
The ALMA-PILS survey: Formaldehyde deuteration in warm gas on small scales toward IRAS 16293-2422 B
M. V. Persson, J. K. Jørgensen, H. S. P. Müller +7
[abridged] The enhanced degrees of deuterium fractionation observed in envelopes around protostars demonstrate the importance of chemistry at low temperatures, relevant in pre- and…
A hidden molecular outflow in the LIRG Zw 049.057
N. Falstad, S. Aalto, J. G. Mangum +8
Feedback in the form of mass outflows driven by star formation or active galactic nuclei is a key component of galaxy evolution. The luminous infrared galaxy Zw 049.057 harbours a…
Relationship between turbulence energy and density variance in the Solar neighbourhood molecular clouds
Jouni Kainulainen, Christoph Federrath
[abridged] We determine the relationship between turbulence energy and gas density variance for 15 molecular clouds in the Solar neighbourhood. We use the linewidths of the CO mole…
Fire from Ice - Massive Star Birth from Infrared Dark Clouds
Jonathan C. Tan
I review massive star formation in our Galaxy, focusing on initial conditions in Infrared Dark Clouds (IRDCs), including the search for massive pre-stellar cores (PSCs), and modeli…
Molecular gas in high-mass filament WB673
M. S. Kirsanova, S. V. Salii, A. M. Sobolev +3
We studied the distribution of dense gas in a filamentary molecular cloud containing several dense clumps. The center of the filament is given by the dense clump WB673. The clumps…
ALMA detections of CO emission in the most luminous, heavily dust-obscured quasars at z>3
Lulu Fan, Kirsten K. Knudsen, Judit Fogasy +1
We report the results of a pilot study of CO emission line of three {\it WISE}-selected hyper-luminous, dust-obscured quasars (QSOs) with sensitive ALMA Band 3 observations.…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
The ortho-to-para ratio of HCl: Quasi-classical trajectory calculations and new simulations in light of new observations
Romane Le Gal, Changjian Xie, Eric Herbst +3
Multi-hydrogenated species with proper symmetry properties can present different spin configurations, and thus exist under different spin symmetry forms, labeled as para and ortho…
Resolved Structure of Arp 220 Nuclei at λ~3 mm
Kazushi Sakamoto, Susanne Aalto, Loreto Barcos-Muñoz +6
We analyze 3 mm emission of the ultraluminous infrared galaxy Arp 220 for spatially-resolved structure and spectral properties of the merger nuclei. ALMA archival data at ~0.05" re…
