SoFiA: a flexible source finder for 3D spectral line data

…, T Westmeier, N Giese, R Jurek, L Flöer… - Monthly Notices of …, 2015 - academic.oup.com
We introduce SoFiA, a flexible software application for the detection and parametrization of
sources in 3D spectral line data sets. SoFiA combines for the first time in a single piece of …

The effelsberg bonn hi survey (ebhis)

J Kerp, B Winkel, N Ben Bekhti, L Flöer… - Astronomische …, 2011 - Wiley Online Library
… Applying a flexible scheduling scheme we now avoid this azimuth range (Flöer et al., in prep…
set and the discussion of the systematic limitations will be presented by Flöer et al. (in prep.). …

Comparison of potential ASKAP HI survey source finders

…, R Jurek, T Westmeier, P Serra, L Flöer… - Publications of the …, 2012 - cambridge.org
The large size of the ASKAP Hi surveys DINGO and WALLABY necessitates automated 3D
source finding. A performance difference of a few percent corresponds to a significant …

2d–1d wavelet reconstruction as a tool for source finding in spectroscopic imaging surveys

L Flöer, B Winkel - Publications of the Astronomical Society of …, 2012 - cambridge.org
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 …

The high-velocity cloud complex Galactic center negative as seen by EBHIS and GASS-I. Cloud catalog and global properties

B Winkel, NB Bekhti, V Darmstädter, L Flöer… - Astronomy & …, 2011 - aanda.org
Using Milky Way data of the new Effelsberg-Bonn H i Survey (EBHIS) and the Galactic All-Sky
Survey (GASS), we present a revised picture of the high-velocity cloud (HVC) complex …

Dust in a compact, cold, high-velocity cloud: A new approach to removing foreground emission

D Lenz, L Flöer, J Kerp - Astronomy & Astrophysics, 2016 - aanda.org
Context. Because isolated high-velocity clouds (HVCs) are found at great distances from the
Galactic radiation field and because they have subsolar metallicities, there have been no …

[HTML][HTML] Far-infrared excess emission as a tracer of disk-halo interaction

D Lenz, J Kerp, L Flöer, B Winkel, F Boulanger… - Astronomy & …, 2015 - aanda.org
Context. Given the current and past star-formation in the Milky Way in combination with the
limited gas supply, the re-fuelling of the reservoir of cool gas is an important aspect of …

EZOA – a catalogue of EBHIS H i-detected galaxies in the northern Zone of Avoidance

AC Schröder, L Flöer, B Winkel… - Monthly Notices of the …, 2019 - academic.oup.com
We present a catalogue of galaxies in the northern Zone of Avoidance (ZoA), extracted from
the shallow version of the blind H i survey with the Effelsberg 100 m radio telescope, EBHIS, …

HI observations of three compact high-velocity clouds around the Milky Way

S Faridani, L Flöer, J Kerp, T Westmeier - Astronomy & Astrophysics, 2014 - aanda.org
Context. We present deep H i observations of three compact high-velocity clouds (CHVCs).Aims.
The main goal is to study their diffuse warm gas and compact cold cores. We use both …
