The O star hinterland of the Galactic starburst, NGC 3603
(2019-06-01)
The very bright and compact massive young cluster, NGC 3603, has been cited as an example of a starburst in the Milky Way and compared with the much-studied R136/30 Doradus region in the Large Magellanic Cloud. Here we ...
The JCMT BISTRO Survey : The Magnetic Field of the Barnard 1 Star-Forming Region
(2019-05-29)
We present the POL-2 850 μm linear polarization map of the Barnard 1 clump in the Perseus molecular cloud complex from the B-fields In STar-forming Region Observations survey at the James Clerk Maxwell Telescope. We find ...
The JCMT BISTRO Survey : The Magnetic Field In The Starless Core $ρ$ Ophiuchus C
(2019-05-22)
We report 850 μm dust polarization observations of a low-mass (∼12 M o) starless core in the ρ Ophiuchus cloud, Ophiuchus C, made with the POL-2 instrument on the James Clerk Maxwell Telescope (JCMT) as part of the JCMT ...
SCOPE : SCUBA-2 Continuum Observations of Pre-protostellar Evolution - Survey Description and Compact Source Catalogue
(2019-05-01)
We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consists of 850 μm continuum observations of 1235 ...
The Gaia Ultra-Cool Dwarf Sample -- II : Structure at the end of the main sequence
(2019-05-01)
We identify and investigate known late M, L, and T dwarfs in the Gaia second data release. This sample is being used as a training set in the Gaia data processing chain of the ultracool dwarfs work package. We find 695 ...
The formation and evolution of low-surface-brightness galaxies
(2019-05-01)
Our statistical understanding of galaxy evolution is fundamentally driven by objects that lie above the surface-brightness limits of current wide-area surveys (μ ∼23 mag arcsec -2). While both theory and small, deep surveys ...
A study of full space motions of outer Galactic disk A and F stars in two deep pencil beams
(2019-05-01)
A and F stars can be used as probes of outer Galactic disc kinematics: here we extend the work of Harris et al. by cross-matching their A/F sample with Gaia DR2 to bring in proper motions. These are combined with the already ...
'The Brick' is not a brick : A comprehensive study of the structure and dynamics of the Central Molecular Zone cloud G0.253+0.016
(2019-05-01)
In this paper we provide a comprehensive description of the internal dynamics of G0.253+0.016 (a.k.a. 'the Brick'); one of the most massive and dense molecular clouds in the Galaxy to lack signatures of widespread star ...
ATLASGAL --- Molecular fingerprints of a sample of massive star forming clumps
(2019-04-21)
We have conducted a 3-mm molecular-line survey towards 570 high-mass star-forming clumps, using the Mopra telescope. The sample is selected from the 10 000 clumps identified by the ATLASGAL (APEX Telescope Large Area Survey ...
The dynamical evolution of molecular clouds near the Galactic Centre - II. Spatial structure and kinematics of simulated clouds
(2019-04-21)
The evolution of molecular clouds in galactic centres is thought to differ from that in galactic discs due to a significant influence of the external gravitational potential. We present a set of numerical simulations of ...
