The Spectral Energy Distribution of Powerful Starburst Galaxies I : Modelling the Radio Continuum
(2018-02-01)
We have acquired radio-continuum data between 70MHz and 48 GHz for a sample of 19 southern starburst galaxies at moderate redshifts (0.067 < z < 0.227) with the aim of separating synchrotron and free-free emission components. ...
The UKIRT Hemisphere Survey: definition and J-band Data Release
(2018-02-01)
This paper defines the UK Infra-Red Telescope (UKIRT) Hemisphere Survey (UHS) and release of the remaining ~12 700 deg 2 of J-band survey data products. The UHS will provide continuous J- and K-band coverage in the Northern ...
The TOP-SCOPE survey of Planck Galactic Cold Clumps : Survey overview and results of an exemplar source, PGCC G26.53+0.17
(2018-02-01)
The low dust temperatures (<14 K) of Planck Galactic cold clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. "TOP-SCOPE" is a joint survey program targeting ∼2000 ...
A Radio Continuum Study of Dwarf Galaxies : 6 cm imaging of Little Things
(2018-02-01)
In this paper, we examine to what extent the radio continuum can be used as an extinction-free probe of star formation in dwarf galaxies. To that aim, we observe 40 nearby dwarf galaxies with the Very Large Array at 6 cm ...
WISDOM Project - III. Molecular gas measurement of the supermassive black hole mass in the barred lenticular galaxy NGC4429
(2018-01-21)
As part of the mm-Wave Interferometric Survey of Dark Object Masses project we present an estimate of the mass of the supermassive black hole (SMBH) in the nearby fast-rotating early-type galaxy NGC4429, that is barred and ...
Was Proxima captured by alpha Centauri A and B?
(2018-01-21)
The nearest stellar system consists of the stars Proxima, Alpha Centauri A and B and at least one planet Proxima b. The habitability of Proxima b and any other planets are likely to be significantly influenced by the orbital ...
The New Galaxy Evolution Paradigm Revealed by the Herschel Surveys
(2018-01-21)
The Herschel Space Observatory has revealed a very different galaxyscape from that shown by optical surveys which presents a challenge for galaxy-evolution models. The Herschel surveys reveal (1) that there was rapid galaxy ...
Photometric redshifts for the next generation of deep radio continuum surveys - I. Template fitting
(2018-01-11)
We present a study of photometric redshift performance for galaxies and active galactic nuclei detected in deep radio continuum surveys. Using two multiwavelength data sets, over the NOAO Deep Wide Field Survey Boötes and ...
`Oumuamua as a messenger from the Local Association
(2018-01-09)
With a hyperbolic trajectory around the Sun, 'Oumuamua is the first confirmed interstellar object. However, its origin is poorly known. By simulating the orbits of 0.23 million local stars, we find 109 encounters with ...
ATLASGAL - properties of a complete sample of Galactic clumps
(2018-01-01)
The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) is an unbiased 870 μm submillimetre survey of the inner Galactic plane (|ℓ| < 60° with |b| < 1.°5). It is the largest and most sensitive ground-based submillimetre ...
