The Lockman Hole project : LOFAR observations and spectral index properties of low-frequency radio sources
(2016-12-11)
The Lockman Hole is a well-studied extragalactic field with extensive multi-band ancillary data covering a wide range in frequency, essential for characterising the physical and evolutionary properties of the various source ...
Highly variable young massive stars in ATLASGAL clumps
(2016-12-05)
High-amplitude variability in Young Stellar Objects (YSOs) is usually associated with episodic accretion events. It has not been observed so far in massive YSOs. Here, the high-amplitude variable star sample of ContrerasPena ...
The space density of luminous dusty star-forming galaxies at $z>4$ : SCUBA-2 and LABOCA imaging of ultrared galaxies from $Herschel$-ATLAS
(2016-11-18)
Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at $z>4$, most of them significantly amplified by gravitational lensing. Here, we have increased the number of such DSFGs substantially, ...
The SCUBA-2 Cosmology Legacy Survey : 850um maps, catalogues and number counts
(2016-11-10)
We present a catalogue of nearly 3,000 submillimetre sources detected at 850um over ~5 square degrees surveyed as part of the James Clerk Maxwell Telescope (JCMT) SCUBA-2 Cosmology Legacy Survey (S2CLS). This is the largest ...
Ocular Shock Front in the Colliding Galaxy IC 2163
(2016-11-04)
ALMA observations in the CO 1 - 0 line of the interacting galaxies IC 2163 and NGC 2207 at 2" x 1.5" resolution reveal how the encounter drives gas to pile up in narrow, ~ 1 kpc wide, "eyelids" in IC 2163. IC 2163 and NGC ...
NIR Tully-Fisher in the Zone of Avoidance. -- III. Deep NIR catalogue of the HIZOA galaxies
(2016-11-01)
We present a deep near-infrared (NIR) photometric catalogue of sources from the Parkes HI Zone of Avoidance (HIZOA) survey, which forms the basis for an investigation of the matter distribution in the Zone of Avoidance. ...
The MIXR sample: AGN activity versus star formation across the cross-correlation of WISE, 3XMM, and FIRST/NVSS
(2016-11-01)
We cross-correlate the largest available Mid-Infrared (WISE), X-ray (3XMM) and Radio (FIRST+NVSS) catalogues to define the MIXR sample of AGN and star-forming galaxies. We pre-classify the sources based on their positions ...
ATCA detections of massive molecular gas reservoirs in dusty, high-z radio galaxies
(2016-10-27)
Observations using the 7 mm receiver system on the Australia Telescope Compact Array have revealed large reservoirs of molecular gas in two high-redshift radio galaxies: HATLAS J090426.9+015448 (z = 2.37) and HATLAS ...
The Herschel-ATLAS Data Release 1 Paper II : Multi-wavelength counterparts to submillimetre sources
(2016-10-21)
This paper is the second in a pair of articles presenting data release 1 (DR1) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS), the largest single open-time key project carried out with the Herschel ...
Variable Stars in the Quintuplet stellar cluster with the VVV Survey
(2016-10-21)
The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic center. We present a new search for variable stars in the vicinity of the cluster, using the five-year ...
