Uncovering the nucleus candidate for NGC 253
G. I. Günthardt, M. P. Agüero, J. A. Camperi +4
NGC253 is the nearest spiral galaxy with a nuclear starburst which becomes the best candidate to study the relationship between starburst and AGN activity. However, this central re…
Gemini Frontier Fields: Wide-field Adaptive Optics -band Imaging of the Galaxy Clusters MACS J0416.1-2403 and Abell 2744
Mischa Schirmer, Rodrigo Carrasco, Peter Pessev +4
We have observed two of the six Frontier Fields galaxy clusters, MACS J0416.1-2403 and Abell 2744, using the Gemini Multi-Conjugate Adaptive Optics System (GeMS) and the Gemini Sou…
THELI -- Convenient reduction of any optical, near- and mid-infrared imaging data
Mischa Schirmer
The last 15 years have seen a surge of new multi-chip optical and near-IR imagers. While some of them are accompanied by specific reduction pipelines, user-friendly and generic red…
Observational and theoretical constraints for an H-halo around the Crab Nebula
A. Tziamtzis, M. Schirmer, P. Lundqvist +1
We searched for a fast moving H shell around the Crab nebula. Such a shell could account for this supernova remnant's missing mass, and carry enough kinetic energy to make SN 10…
The Garching-Bonn Deep Survey (GaBoDS) Wide-Field-Imaging Reduction Pipeline
H. Hildebrandt, T. Erben, M. Schirmer +2
We introduce our publicly available Wide-Field-Imaging reduction pipeline THELI. The procedures applied for the efficient pre-reduction and astrometric calibration are presented. A…
Searching dark-matter halos in the GaBoDS survey
M. Maturi, M. Schirmer, M. Meneghetti +2
We apply the linear filter for the weak-lensing signal of dark-matter halos developed in Maturi et al. (2005) to the cosmic-shear data extracted from the Garching-Bonn-Deep-Survey…
