Outflow from Outer-arm Starburst in a Grazing Collision between Galaxies
(2020-04)
New ALMA CO, HCO+, and 100 GHz continuum observations and Gemini NIFS K-band spectra are combined with previous radio to X-ray data to study Feature i, a highly luminous starburst clump on an outer arm of the interacting ...
The MALATANG Survey : Dense Gas and Star Formation from High Transition HCN and HCO+ maps of NGC253
(2020-03-24)
To study the high-transition dense-gas tracers and their relationships to the star formation of the inner $\sim$ 2 kpc circumnuclear region of NGC253, we present HCN $J=4-3$ and HCO$^+ J=4-3$ maps obtained with the James ...
VVV-WIT-01: highly obscured classical nova or protostellar collision?
(2020-03)
A search of the first Data Release of the VISTA Variables in the Via Lactea (VVV) Survey discovered the exceptionally red transient VVV-WIT-01 (H-Ks=5.2). It peaked before March 2010, then faded by ~9.5 mag over the following ...
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field : Dust attenuation in high-redshift Lyman break Galaxies
(2020-03)
We analyse 870um Atacama Large Millimetre Array (ALMA) dust continuum detections of 41 canonically-selected z~3 Lyman-break galaxies (LBGs), as well as 209 ALMA-undetected LBGs, in follow-up of SCUBA-2 mapping of the UKIDSS ...
Giant radio galaxies in the LOFAR Two-metre Sky Survey-I
(2020-03-01)
Giant radio galaxies (GRGs) are a subclass of radio galaxies which have grown to megaparsec scales. GRGs are much rarer than normal sized radio galaxies ( less than 0.7 Mpc) and the reason for their gigantic sizes is still ...
LOFAR view of NGC 3998, a sputtering AGN
(2020-02-18)
Low-power radio sources dominate the radio sky. They tend to be small in size and dominated by their cores, but the origin of their properties and the evolution of their radio plasma are not well constrained. Interestingly, ...
L-galaxies 2020: Spatially resolved cold gas phases, star formation and chemical enrichment in galactic discs
(2020-02-01)
We have updated the Munich galaxy formation model, L-Galaxies, to follow the radial distributions of stars and atomic and molecular gas in galaxy discs. We include an H2-based star-formation law, as well as a detailed ...
