2D-1D Wavelet Reconstruction As A Tool For Source Finding In Spectroscopic Imaging Surveys
Lars Flöer, Benjamin Winkel
Today, image denoising by thresholding of wavelet coefficients is a commonly used tool for 2D image enhancement. Since the data product of spectroscopic imaging surveys has two spa…
The high-velocity cloud complex Galactic Center Negative as seen by EBHIS and GASS. I. Cloud catalog and global properties
Benjamin Winkel, Nadya Ben Bekhti, Verena Darmstädter +3
Using Milky Way data of the new Effelsberg-Bonn HI Survey (EBHIS) and the Galactic All-Sky Survey (GASS), we present a revised picture of the high-velocity cloud (HVC) complex Gala…
The Effelsberg-Bonn HI Survey (EBHIS)
Juergen Kerp, Benjamin Winkel, Nadya Ben Bekhti +2
The Effelsberg-Bonn HI survey (EBHIS) comprises an all-sky survey north of Dec = -5 degrees of the Milky Way and the local volume out to a red-shift of z ~ 0.07. Using state of the…
On the origin of gaseous galaxy halos - Low-column density gas in the Milky Way halo
N. Ben Bekhti, B. Winkel, P. Richter +2
Recent observations show that spiral galaxies are surrounded by extended gaseous halos as predicted by the hierarchical structure formation scenario. The origin and nature of extra…
