Environmental effects in galaxy clusters : Infalling groups in Abell 85 and 1367
(2010-12-01)
We are carrying out a multifrequency survey of late type galaxies in nearby clusters with the aim to investigate the effects exerted by both the very local and the global cluster environments. We report new VLA-HI images ...
Stellar population variations in the Milky Way's stellar halo
(2010-12)
If the stellar halos of disk galaxies are built up from the disruption of dwarf galaxies, models predict highly structured variations in the stellar populations within these halos. We test this prediction by studying the ...
Investigating the merger origin of early-type galaxies using ultra-deep optical images
(2010-12-01)
The mass assembly of galaxies leaves various imprints on their surroundings, such as shells, streams and tidal tails. The frequency and properties of these fine structures depend on the mechanism driving the mass assembly: ...
Molecular gas and star formation in local early-type galaxies
(2010-12-01)
The molecular gas content of local early-type galaxies is constrained and discussed in relation to their evolution. First, as part of the ATLAS survey, we present the first complete, large (260 objects), volume-limited ...
FIELD AND GLOBULAR CLUSTER LOW-MASS X-RAY BINARIES IN NGC 4278
(2010-12)
We report a detailed spectral analysis of the population of low-mass X-ray binaries (LMXBs) detected in the elliptical galaxy NGC 4278 with Chandra. Seven luminous sources were studied individually, four in globular clusters ...
The X-ray spectra of the luminous LMXBs in NGC 3379 : field and globular cluster sources
(2010-12)
From a deep multi-epoch Chandra observation of the elliptical galaxy NGC 3379 we report the spectral properties of eight luminous LMXBs (L-X > 1.2 x 10(38) erg s(-1)). We also present a set of spectral simulations, produced ...
Adaptation to increasing severity of phoma stem canker on winter oilseed rape in the UK under climate change
(2010-12)
Various adaptation strategies are available that will minimize or negate predicted climate change-related increases in yield loss from phoma stem canker in UK winter oilseed rape (OSR) production. A number of forecasts for ...
Overview of optical local access networks development and design challenges
(2010-12-01)
Local access network technologies tend to take advantage of the potentially huge capabilities of fiber communication to deliver faster and more various services to end users. There has been considerable research effort in ...
Undergraduate students' view of multidisciplinary working over a 3-year study on interprofessional simulation learning
(2010-12-01)
Introduction: Interprofessional simulation training at undergraduate level has been tested (1) but is still very scarce due to curriculum and logistical issues. Our simulation specialists worked with staff from most health ...
Physical activity and mental health in a student population
(2010-12)
Aims: The present study investigates the association between physical activity and mental health in an undergraduate university population based in the United Kingdom. Method: One hundred students completed questionnaires ...
