The ATLAS3D project - XXIV : The intrinsic shape distribution of early-type galaxies
(2014-11-11)
We use the ATLAS<sup>3D</sup> sample to perform a study of the intrinsic shapes of early-type galaxies, taking advantage of the available combined photometric and kinematic data. Based on our ellipticity measurements from ...
GALAPAGOS-C : Analysis of galaxy morphologies using high-performance computing methods
(2014-11-11)
We present GALAPAGOS-C, a code designed to process a complete set of survey images through automation of source detection (via SEXTRACTOR), postage stamp cutting, object mask preparation, sky background estimation and ...
Milky Way demographics with the VVV survey III : Evidence for a great dark lane in the 157 million star bulge color-magnitude diagram
(2014-11)
The new generation of IR surveys are revealing and quantifying Galactic features that provide an improved 3D interpretation of our own Galaxy. We present an analysis of the global distribution of dust clouds in the bulge ...
The debris disc of solar analogue Τ Ceti : Herschel observations and dynamical simulations of the proposed multiplanet system
(2014-11-01)
Τ Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue and possible multiplanet system that has been compared to our Solar system. We present Herschel Space Observatory images ...
Near-infrared circular polarization survey in star-forming regions : Correlations and trends
(2014-11-01)
We have conducted a systematic near-infrared circular polarization (CP) survey in star-forming regions, covering high-mass, intermediate-mass, and low-mass young stellar objects. All the observations were made using the ...
The curious case of HD 41248. A pair of static signals buried behind red noise
(2014-10-20)
Gaining a better understanding of the effects of stellar-induced radial velocity noise is critical for the future of exoplanet studies since the discovery of the lowest-mass planets using this method will require us to go ...
A 3D extinction map of the northern Galactic plane based on IPHAS photometry
(2014-10-01)
We present a 3D map of extinction in the northern Galactic plane derived using photometry from the INT/WFC Photometric Hα Survey of the northern Galactic plane. The map has fine angular (~10 arcmin) and distance (100 pc) ...
The VMC survey - XII : Star cluster candidates in the large magellanic cloud
(2014-10)
In this work we analyse colour-magnitude diagrams (CMDs) of catalogued star clusters located in the Large Magellanic Cloud (LMC), from a YJKs photometric data set obtained by the Visible and Infrared Survey Telescope for ...
Lofar low-band antenna observations of the 3C 295 and boötes fields : Source counts and ultra-steep spectrum sources
(2014-10-01)
We present Low Frequency Array (LOFAR) Low Band observations of the Boötes and 3C 295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam-1, making them the deepest images ever obtained ...
A relationship between specific star formation rate and metallicity gradient within z ~ 1 galaxies from KMOS-HiZELS
(2014-09-21)
We have observed a sample of typical z ~ 1 star-forming galaxies, selected from the HiZELS survey, with the new K-band Multi-Object Spectrograph (KMOS) near-infrared, multi-integral field unit instrument on the Very Large ...
