Precision simulation of ground-based lensing data using observations from space
methods: data analysis – techniques: image processing – gravitational lensing: weak – galaxies: structure
2011/10/13
Current and upcoming wide-field, ground-based, broad-band imaging surveys promise to address a wide range of outstanding problems in galaxy formation and cosmology. Several such uses of ground-based d...
The Stability of Low Surface Brightness Disks Based on Multi-Wavelength Modeling
Stability Surface Brightness Disks Based Multi-Wavelength Modeling
2011/10/18
To investigate the structure and composition of the dusty interstellar medium (ISM) of low surface brightness (LSB) disk galaxies, we have used multiwavelength photometry to construct spectral energy ...
The Demographics of Broad-Line Quasars in the Mass-Luminosity Plane. I. Testing FWHM-Based Virial Black Hole Masses
Demographics Broad-Line Quasars Mass-Luminosity Plane
2011/10/13
We jointly constrain the LF and BHMF of quasars using a Bayesian approach that describes the underlying active BHMF and Eddington ratio distribution to match the observed distributions in the quasar m...
Halo based reconstruction of the cosmic mass density field
galaxies: haloes – groups: general– cosmology: dark matter – large-scale structure of Universe – methods: numerical
2011/9/28
We present the implementation of a halo based method for the reconstruction of the cosmic mass density field. The method employs the mass density distribution of dark matter haloes and its environment...

ATTENUATION LAW FOR GALAXIES WITH DIFFERENT STAR FORMATION HISTORIES, BASED ON THE SDSS IMAGES
Galaxies: photometry Galaxies: ISM Galaxies: stellar content
2010/10/29
Attenuation curves (laws) in the optical part of the spectrum (from about 3500 ºA to 9000 ºA) are determined for galaxies with di®erent star formation histories (SFHs) using images in &m...
