Imprints of dynamical dark energy on weak-lensing measurements (2009)
Chongchitnan, Sirichai, King, Lindsay
We show that simple models of dynamical dark energy leave an all-scale enhancement in the weak-lensing power spectrum when compared to the LCDM prediction. In particular, we calculate the convergence...
Cluster Mass Profiles from Weak Lensing: Shear vs. Magnification Information (2007)
Peter Schneider, Lindsay King, Thomas Erben
A massive foreground cluster lens changes the shapes (shear effect) and number density (magnification effect) of the faint background galaxy population. In this paper we investigate how the shear,...
In this paper we discuss the biases and selection effects relevant to the Jodrell Bank -- VLA gravitational lens survey (JVAS). We present a method for the determination of the magnification bias and...
Cosmic shear constrains cosmology by exploiting the apparent alignments of pairs of galaxies due to gravitational lensing by intervening mass clumps. However galaxies may become (intrinsically)...
King, Lindsay, Corless, Virginia
The distribution of mass on galaxy cluster scales is an important test of structure formation scenarios, providing constraints on the nature of dark matter itself. Several techniques have been used...
Cluster Masses from CMB and Galaxy Weak Lensing (2005)
Gravitational lensing can be used to directly constrain the projected density profile of galaxy clusters. We discuss possible future constraints from lensing of the CMB temperature and polarization,...
Cosmic shear leads to a correlation of the observed ellipticities of galaxies, an effect which is used to place constraints on cosmological parameters, and to explore the evolution of dark matter and...
Separating cosmic shear from intrinsic galaxy alignments: correlation function tomography (2002)
King, Lindsay, Schneider, Peter
During the past few years, secure detections of cosmic shear have been obtained, manifest in the correlation of the observed ellipticities of galaxies. Constraints have already been placed on...
King, Lindsay, Schneider, Peter
Cosmological weak lensing gives rise to correlations in the ellipticities of faint galaxies. This cosmic shear signal depends upon the matter power spectrum, thus providing a means to constrain...
Parameterised models for the lensing cluster Abell 1689 (2001)
King, Lindsay, Clowe, Douglas, Schneider, Peter
Here we apply a recently developed maximum likelihood method for determining best-fit parameterised lens models to observations of the rich lensing cluster Abell 1689. The observations that we use...
Weak-Lensing Halo Numbers and Dark-Matter Profiles (2001)
Bartelmann, Matthias, King, Lindsay, Schneider, Peter
Integral measures of weak gravitational lensing by dark-matter haloes, like the aperture mass, are sensitive to different physical halo properties dependent on the halo mass density profile. For...
Cluster Mass Profiles from Weak Lensing II (2000)
King, Lindsay, Schneider, Peter
In Schneider, King & Erben (2000) we developed likelihood techniques to compare the constraints on cluster mass profiles that can be obtained using the shear and magnification information. This work...
Cluster mass profiles from weak lensing: shear vs. magnification information (1999)
Schneider, Peter, King, Lindsay, Erben, Thomas
A massive foreground cluster lens changes the shapes (shear effect) and number density (magnification effect) of the faint background galaxy population. In this paper we investigate how the shear,...
Serjeant, Stephen, Lacy, Mark, Rawlings, Steve, King, Lindsay, Clements, D. L.
The extreme bolometric luminosity of IRAS F10214+4724, and in particular the huge mass in molecular gas inferred from the CO line fluxes have led to suggestions that this is a giant galaxy in the...
