A lensing view on the Fundamental Plane


Leier, D (2009). A lensing view on the Fundamental Plane. Monthly Notices of the Royal Astronomical Society, 400(2):875-886.

Abstract

For lensing galaxies, we introduce a formal velocity dispersion σlens , based on enclosed mass and the virial theorem. This is calculated from an ensemble of pixelated lens models, and found to be fairly model-independent. A sample of 18 well-known early-type lensing galaxies and two clusters is found to be consistent with σlens=σobs . Both the early-type lensing galaxies and the clusters can thus be determined as being virialized. In a second step, we calculate the I-band luminosity and the total mass content for the sample of lensing galaxies, which enables us to analyse the mass-to-light relation L∝Mα . We determine α= 0.70 ± 0.08 , excluding constant M/L and consistent with previous studies of the Fundamental Plane. Additionally, we verify that this relation does not extrapolate to clusters, which have a much higher M/L. The sample used for this analysis comprises nine lensing galaxies from the Sloan Lens ACS (Advanced Camera for Surveys) Survey and another nine from the CfA-Arizona Space Telescope LEns Survey as well as the lensing clusters ACO 1689 and ACO 2667.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
