The Gamma-Ray Blazar PKS 0208-512, a Multi-Wavelength Investigation
Gamma-Ray Blazar PKS 0208-512 Multi-Wavelength Investigation
2012/2/23
The gamma-ray blazar PKS 0208-512 has shown strong periods of flaring, at all frequencies from radio to gamma-ray. This has led to its inclusion in the TANAMI project, which tracks the jets of souther...
Improved Constraints on Type Ia Supernova Host Galaxy Properties using Multi-Wavelength Photometry and their Correlations with Supernova Properties
Improved Constraints Supernova Galaxy Properties Multi-Wavelength Photometry Correlations Supernova Properties
2011/10/18
We improve estimates of stellar mass and mass-weighted average age of Type Ia supernova (SN Ia) host galaxies by combining UV and near-IR photometry with optical photometry in our analysis. Using 206 ...
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 ...
Multi-wavelength observations of the young binary system Haro 6-10: The case of misaligned discs
Binary stars - Star Formation - Haro 6-10
2011/10/17
Context. We present a multi-wavelength, high-resolution observational survey of the young binary system Haro 6-10 (GV Tau, IRAS 04263+2426), which is harbouring one of the few known infrared companion...

In these proceedings I discuss a range of surveys that are currently underway at optical, near-infrared and far-infrared wavelengths that have large components accessible to both the Southern African ...
A mid-IR study of Hickson Compact Groups II. Multi-wavelength analysis of the complete GALEX-Spitzer Sample
Infrared: galaxies —Galaxies: evolution— Galaxies: interactions —Galaxies: star formation
2011/10/10
We present a comprehensive study on the impact of the environment of compact galaxy groups on the evolution of their members using a multi-wavelength analysis, from the UV to the infrared, for a sampl...
Multi-wavelength modeling of the spatially resolved debris disk of HD 107146
Stars: individual: high angular resolution – Methods: stars
2011/9/28
We aim to constrain the location, composition, and dynamical state of planetesimal populations and dust around the young, sun-like (G2V) star HD 107146}. We consider coronagraphic observations obtaine...
