JINGLE, a JCMT legacy survey of dust and gas for galaxy evolution studies : II. SCUBA-2 850 μm data reduction and dust flux density catalogues
(2019-07-01)
We present the SCUBA-2 850μ m component of JINGLE, the new JCMT large survey for dust and gas in nearby galaxies, which with 193 galaxies is the largest targeted survey of nearby galaxies at 850 μ m. We provide details of ...
Unveiling the 100 pc scale nuclear radio structure of NGC 6217 with e-MERLIN and the VLA
(2019-07-01)
We present high-sensitivity 1.51 GHz e-MERLIN (e-Multi-Element Radio-Linked Interferometer Network) radio images of the nearby galaxy NGC6217. We resolve the compact radio source at the centre of NGC6217 for the first time, ...
A flat trend of star-formation rate with X-ray luminosity of galaxies hosting AGN in the SCUBA-2 Cosmology Legacy Survey
(2019-07-01)
Feedback processes from active galactic nuclei (AGN) are thought to play a crucial role in regulating star formation in massive galaxies. Previous studies using Herschel have resulted in conflicting conclusions as to whether ...
The Dynamics and Distribution of Angular Momentum in HiZELS Star-Forming Galaxies at z = 0.8 - 3.3
(2019-06)
We present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at z = 0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics of the ionized interstellar medium on ∼1 kpc ...
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 case for a 'sub-millimeter SDSS' : a 3D map of galaxy evolution to z~10
(2019-05-31)
The Sloan Digital Sky Survey (SDSS) was revolutionary because of the extraordinary breadth and ambition of its optical imaging and spectroscopy. We argue that a 'sub-millimeter SDSS' - a sensitive large-area imaging+spectroscopic ...
A 1D fluid model of the Centaurus A jet
(2019-05-01)
We implement a steady, one-dimensional flow model for the X-ray jet of Centaurus A in which entrainment of stellar mass loss is the primary cause of dissipation. Using over 260 ks of new and archival Chandra/ACIS data, we ...
The dynamical evolution of molecular clouds near the Galactic Centre -- III. Tidally--induced star formation in protocluster clouds
(2019-04-02)
As part of a series of papers aimed at understanding the evolution of the Milky Way's Central Molecular Zone (CMZ), we present hydrodynamical simulations of turbulent molecular clouds orbiting in an accurate model of the ...
Disentangling the spatial substructure of Cygnus OB2 from Gaia DR2
(2019-04-01)
For the first time, we have explored the spatial substructure of the Cygnus OB2 association using parallaxes from the recent second Gaia data release. We find significant line-of-sight substructure within the association, ...
The metallicity and elemental abundance maps of kinematically atypical galaxies for constraining minor merger and accretion histories
(2019-03-06)
Explaining the internal distribution and motions of stars and gas in galaxies is a key aspect in understanding their evolution. In previous work we identified five well-resolved galaxies with atypical kinematics from a ...
