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 ...
