High proper motion objects from the UKIDSS Galactic plane survey
(2014-09-21)
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a seven year effort to survey ~1800 deg2 of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K-band data, with a baseline ...
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 ...
The Gaia-ESO Survey : Stellar content and elemental abundances in the massive cluster NGC 6705
(2014-09)
Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical ...
New galactic star clusters discovered in the VVV survey : Candidates projected on the inner disk and bulge
(2014-09)
Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent ...
Imaging the environment of A z = 6.3 submillimeter galaxy with scuba-2
(2014-08-28)
We describe a search for submillimeter emission in the vicinity of one of the most distant, luminous galaxies known, HerMES FLS3, at z = 6.34, exploiting it as a signpost to a potentially biased region of the early universe, ...
Filaments in the southern giant lobe of Centaurus A : Constraints on nature and origin from modelling and GMRT observations
(2014-08-21)
We present results from imaging of the radio filaments in the southern giant lobe of CentaurusA using data from Giant Metrewave Radio Telescope observations at 325 and 235 MHz, and outcomes from filament modelling. The ...
The angular clustering of infrared-selected obscured and unobscured quasars
(2014-08-21)
Recent studies of luminous infrared-selected active galactic nuclei (AGN) suggest that the reddest, most obscured objects display a higher angular clustering amplitude, and thus reside in higher mass darkmatter haloes. ...
GJ 832c : A super-earth in the habitable zone
(2014-08-05)
We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly circular 9.4 yr orbit. The combination of ...
Diffuse gas in galaxies sheds new light on the origin of Type Ia supernovae
(2014-08-01)
We measure the strength of He II λ4686 nebular emission in passively evolving ('retired') galaxies, aiming to constrain their populations of hot accreting white dwarfs (WDs) in the context of the single-degenerate (SD) ...
Massive compact galaxies with high-velocity outflows : Morphological analysis and constraints on AGN activity
(2014-07-11)
We investigate the process of rapid star formation quenching in a sample of 12 massive galaxies at intermediate redshift (z ~ 0.6) that host high-velocity ionized gas outflows (v > 1000 km s-1). We conclude that these fast ...
