The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
(2023-03-11)
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, ...
The O star hinterland of the Galactic starburst, NGC 3603
(2019-06-01)
The very bright and compact massive young cluster, NGC 3603, has been cited as an example of a starburst in the Milky Way and compared with the much-studied R136/30 Doradus region in the Large Magellanic Cloud. Here we ...
Disentangling the spatial substructure of Cygnus OB2 from Gaia DR2
(2019-04-01)
For the first time, we have explored the spatial substructure of the Cygnus OB2 association using parallaxes from the recent second Gaia data release. We find significant line-of-sight substructure within the association, ...
A Tale of Three Cities : OmegaCAM discovers multiple sequences in the color-magnitude diagram of the Orion Nebula Cluster
(2017-07-27)
As part of the Accretion Discs in H$\alpha$ with OmegaCAM (ADHOC) survey, we imaged in r, i and H-alpha a region of 12x8 square degrees around the Orion Nebula Cluster. Thanks to the high-quality photometry obtained, we ...
Physical parameters of IPHAS-selected classical Be stars. (I. Determination procedure and evaluation of the results.)
(2016-07-01)
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotometric system. Our aim is to apply this ...
A search for white dwarfs in the Galactic plane: : the field and the open cluster population
(2016-04-01)
We investigated the prospects for systematic searches of white dwarfs at low Galactic latitudes, using the VLT Survey Telescope (VST) H$\alpha$ Photometric Survey of the Galactic plane and Bulge (VPHAS+). We targeted 17 ...
Calibrated and completeness-corrected optical stellar density maps of the Northern Galactic Plane
(2016-03-21)
Following on from the second release of calibrated photometry from IPHAS, the INT/WFC Photometric Hα Survey of the Northern Galactic Plane, we present incompleteness-corrected stellar density maps in the r and i photometric ...
