The Gaia/IPHAS and Gaia/KIS value-added catalogues
(2018-12-11)
We present a sub-arcsecond crossmatch of Gaia DR2 against the INT Photometric Ha Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2) and the Kepler-INT Survey (KIS). The resulting value-added catalogues (VACs) ...
The XXL Survey: : XXIX. GMRT 610 MHz continuum observations
(2018-12-01)
We present the 25 square-degree GMRT-XXL-N 610 MHz radio continuum survey, conducted at 50 cm wavelength with the Giant Metrewave Radio Telescope (GMRT) towards the XXL Northern field (XXL-N). We combined previously published ...
Milky Way demographics with the VVV survey. IV. PSF photometry from almost one billion stars in the Galactic bulge and adjacent southern disk
(2018-11-01)
Context. The inner regions of the Galaxy are severely affected by extinction, which limits our capability to study the stellar populations present there. The Vista Variables in the Vía Láctea (VVV) ESO Public Survey has ...
Massive stars in the hinterland of the young cluster, Westerlund 2
(2018-10-21)
An unsettled question concerning the formation and distribution of massive stars is whether they must be born in massive clusters and, if found in less dense environments, whether they must have migrated there. With the ...
A new near-IR window of low extinction in the Galactic plane
(2018-08-01)
Aims. The windows of low extinction in the Milky Way (MW) plane are rare but important because they enable us to place structural constraints on the opposite side of the Galaxy, which has hither to been done rarely. Methods. ...
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 ...
