The SAURON project - XIX : Optical and near-infrared scaling relations of nearby elliptical, lenticular and Sa galaxies
(2011-11-01)We present ground-based MDM Observatory V-band and Spitzer/InfraRed Array Camera 3.6-m-band photometric observations of the 72 representative galaxies of the SAURON survey. Galaxies in our sample probe the elliptical E, ... -
The SAURON Project - XV. Modes of star formation in early-type galaxies and the evolution of the red sequence
(2010)We combine SAURON integral field data of a representative sample of local early-type, red sequence galaxies with Spitzer/Infrared Array Camera imaging in order to investigate the presence of trace star formation in these ... -
The SAURON project - XVIII : The integrated UV-line-strength relations of early-type galaxies
(2011-07)Using far-ultraviolet (FUV) and near-ultraviolet (NUV) photometry from guest investigator programmes on the Galaxy Evolution Explorer (GALEX) satellite, optical photometry from the MDM Observatory and optical integral-field ... -
The SAURON Project - XX. The Spitzer [3.6] - [4.5] colour in early-type galaxies : Colours, colour gradients and inverted scaling relations
(2012-01)We investigate the [3.6]-[4.5] Spitzer-IRAC colour behaviour of the early-type galaxies of the SAURON survey, a representative sample of 48 nearby ellipticals and lenticulars. We investigate how this colour, which is ... -
The SAURON project - XXI : The spatially resolved UV-line strength relations of early-type galaxies
(2012-06)The unexpected rising flux of early-type galaxies at decreasing ultraviolet (UV) wavelengths is a long-standing mystery. One important observational constraint is the correlation between UVoptical colours and Mg2 line ... -
The SAURON project – XIII. SAURON–GALEX study of early-type galaxies: the ultraviolet colour–magnitude relations and Fundamental Planes
(2009)We present Galaxy Evolution Explorer far-ultraviolet (FUV) and near-ultraviolet (NUV) imaging of 34 nearby early-type galaxies from the SAURON representative sample of 48 E/S0 galaxies, all of which have ground-based optical ... -
The SAURON Project – XIV. No escape from Vesc: a global and local parameter in early-type galaxy evolution
(2009)We present the results of an investigation of the local escape velocity (Vesc) - line strength index relationship for 48 early type galaxies from the SAURON sample, the first such study based on a large sample of galaxies ... -
The SAURON project – XVI : On the sources of ionization for the gas in elliptical and lenticular galaxies
(2010)Following our study on the incidence, morphology and kinematics of the ionized gas in early-type galaxies, we now address the question of what is powering the observed nebular emission. To constrain the likely sources of ... -
The SAURON project – XVII. Stellar population analysis of the absorption line strength maps of 48 early-type galaxies
(2010)We present a stellar population analysis of the absorption line strength maps for 48 early-type galaxies from the SAURON sample. Using the line strength index maps of Hβ, Fe5015 and Mg b, measured in the Lick/IDS system ... -
"Saying is one thing: doing is another" : the role of observation in marketing research
(1999)Observation does not often appear as a research methodology in the marketing literature: this may be because it is sometimes hard to quantify the outcomes of observational research at the outset, or because it is considered ... -
Saying “welcome” is not enough : women, information systems and equity in work
(2000)The rise of all forms of information systems has been one of the major factors affecting the nature of work over the last decade. This article reports on research that suggests that whilst females may now gain more experience ... -
SB 201823-A, A neuronal Ca antagonist is neuroprotective in two models of cerebral ischaemia
(1993)We have characterised the Ca2+ channel blocking properties of a new non-peptide Ca2+ channel antagonist, SB 201823-A, in cultures of rat sensory neurones. The IC50 for SB 201823-A against total Ca2+ current in sensory ... -
SB 205384 slows the decay of GABA-activated chloride currents in granule cells cultured from rat cerebellum
(1997)4-Amino-7-hydroxy-2-methyl-5,6,7,8,-tetrahydrobenzo[b]thieno[2,3-b]pyridine-3-carboxylic acid, but-2-ynyl ester (SB-205384) and other γ-aminobutyric acidA (GABAA) receptor modulators were tested for their effects on ...
