Near-Infrared spectral diagnostics for unresolved stellar population galaxies
M. Cesetti, V. D. Ivanov, L. Morelli
We want to develop spectral diagnostics of stellar populations in the near-infrared (NIR), for unresolved stellar populations. We created a semi-empirical population model and we c…
Characterizing Barred Galaxies in the Abell 901/902 Supercluster
I. Marinova, S. Jogee, D. Bacon +22
In dense clusters, higher densities at early epochs as well as physical processes, such as ram pressure stripping and tidal interactions become important, and can have direct conse…
Imaging the 3-D cosmological mass distribution with weak gravitational lensing
A. N. Taylor
I show how weak gravitational lensing can be used to image the 3-D mass distribution in the Universe. An inverse relation to the lensing equation, relating the lensing potential ev…
Lens magnification by CL0024+1654 in the U and R band
S. Dye, A. N. Taylor, T. R. Greve +6
[ABRIDGED] We estimate the total mass distribution of the galaxy cluster CL0024+1654 from the measured source depletion due to lens magnification in the R band. Within a radius of…
Application of Data Compression Methods to the Redshift-space distortions of the PSCz galaxy catalogue
A. N. Taylor, W. E. Ballinger, A. F. Heavens +1
We apply a spherical harmonic analysis to the Point Source Redshift Survey (PSCz), to compute the real-space galaxy power spectrum and the degree of redshift distortion caused by p…
Redshift Distortions and Clustering in the PSCz Survey
W. E. Ballinger, A. N. Taylor, A. F. Heavens +1
We have constrained the redshift-distortion parameter and the real-space power spectrum of the IRAS PSCz survey using a spherical-harmonic redshift-distortion a…
