ATLASGAL -- Relationship between dense star forming clumps and interstellar masers
(2020-09-29)
We have used catalogues from several Galactic plane surveys and dedicated observations to investigate the relationship between various maser species and Galactic star forming clumps, as identified by the ATLASGAL survey. ...
Discovery of a mid-infrared protostellar outburst of exceptional amplitude
(2020-09-23)
We report the discovery of a mid-infrared outburst in a Young Stellar Object (YSO) with an amplitude close to 8 mag at lambda ~ 4.6 microns. WISEA J142238.82-611553.7 is one of 23 highly variable WISE sources discovered ...
MeerKAT HI commissioning observations of MHONGOOSE galaxy ESO 302-G014
(2020-09-22)
We present the results of three commissioning HI observations obtained with the MeerKAT radio telescope. These observations make up part of the preparation for the forthcoming MHONGOOSE nearby galaxy survey, which is a ...
The Origin of Elements from Carbon to Uranium
(2020-09-15)
To reach a deeper understanding of the origin of elements in the periodic table, we construct Galactic chemical evolution (GCE) models for all stable elements from C (A = 12) to U (A = 238) from first principles, i.e., ...
CHIMPS2 : Survey description and $^{12}$CO emission in the Galactic Centre
(2020-09-10)
The latest generation of Galactic-plane surveys is enhancing our ability to study the effects of galactic environment upon the process of star formation. We present the first data from CO Heterodyne Inner Milky Way Plane ...
Eigengalaxies: describing galaxy morphology using principal components in image space
(2020-09-02)
We demonstrate how galaxy morphologies can be represented by weighted sums of "eigengalaxies" and how eigengalaxies can be used in a probabilistic framework to enable principled and simplified approaches in a variety of ...
Alignment in the orientation of LOFAR radio sources
(2020-08-25)
Various studies have laid claim to finding an alignment of the polarization vectors or radio jets of active galactic nuclei (AGN) over large distances, but these results have proven controversial and so far, there is no ...
Molecular Cloud Cores with High Deuterium Fraction : Nobeyama Single-Pointing Survey
(2020-08-12)
We present the results of a single-pointing survey of 207 dense cores embedded in Planck Galactic Cold Clumps distributed in five different environments ($\lambda$ Orionis, Orion A, B, Galactic plane, and high latitudes) ...
The JCMT BISTRO Survey : Magnetic Fields Associated with a Network of Filaments in NGC 1333
(2020-08-10)
We present new observations of the active star-formation region NGC 1333 in the Perseus molecular cloud complex from the James Clerk Maxwell Telescope B-Fields In Star-forming Region Observations (BISTRO) survey with the ...
Oxygen Loss from Simulated Galaxies and the Metal Flow Main Sequence : Predicting the Dependence on Mass and Environment
(2020-08-01)
We predict the mass fraction of oxygen lost from galaxies in a cosmological simulation as a function of stellar mass and environment at the present day. The distribution with stellar mass is bimodal, separating star-forming ...
