An HST/COS legacy survey of high-velocity ultraviolet absorption in the Milky Way's circumgalactic medium and the Local Group
P. Richter, S. E. Nuza, A. J. Fox +9
To characterize the absorption properties of this circumgalactic medium (CGM) and its relation to the LG we present the so-far largest survey of metal absorption in Galactic high-v…
High-resolution HI and CO observations of high-latitude intermediate-velocity clouds
T. Röhser, J. Kerp, N. Ben Bekhti +1
Intermediate-velocity clouds (IVCs) are HI halo clouds that are likely related to a Galactic fountain process. In-falling IVCs are candidates for the re-accretion of matter onto th…
Structure and Kinematics of the Nearby Dwarf Galaxy UGCA 105
Philip Schmidt, Gyula Jozsa, Gianfranco Gentile +5
Owing to their shallow stellar potential, dwarf galaxies possess thick gas disks, which makes them good candidates for studies of the galactic vertical kinematical structure. We pr…
High-resolution absorption spectroscopy of the circumgalactic medium of the Milky Way
P. Richter, A. J. Fox, N. Ben Bekhti +3
In this article we discuss the importance of high-resolution absorption spectroscopy for our understanding of the distribution and physical nature of the gaseous circumgalactic med…
The COS/UVES Absorption Survey of the Magellanic Stream: I. One-Tenth Solar Abundances along the Body of the Stream
Andrew J. Fox, Philipp Richter, Bart P. Wakker +5
The Magellanic Stream (MS) is a massive and extended tail of multi-phase gas stripped out of the Magellanic Clouds and interacting with the Galactic halo. In this first paper of an…
The COS/UVES Absorption Survey of the Magellanic Stream: II. Evidence for a complex enrichment history of the Stream from the Fairall 9 sightline
Philipp Richter, Andrew J. Fox, Bart P. Wakker +5
We present a multi-wavelength study of the Magellanic Stream (MS), a massive gaseous structure in the Local Group that is believed to represent material stripped from the Magellani…
GASKAP -- The Galactic ASKAP Survey
J. M. Dickey, N. McClure-Griffiths, S. J. Gibson +55
A survey of the Milky Way disk and the Magellanic System at the wavelengths of the 21-cm atomic hydrogen (HI) line and three 18-cm lines of the OH molecule will be carried out with…
An absorption-selected survey of neutral gas in the Milky Way halo
N. Ben Bekhti, B. Winkel, P. Richter +3
We aim at analysing systematically the distribution and physical properties of neutral and mildly ionised gas in the Milky Way halo, based on a large absorption-selected data set.…
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…
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…
Absorption and emission line studies of gas in the Milky Way halo
N. Ben Bekhti, P. Richter, B. Winkel +4
We perform a systematic study of physical properties and distribution of neutral and ionised gas in the halo of the Milky Way (MW). Beside the large neutral intermediate- and high-…
The Effelsberg-Bonn HI Survey: Milky Way data
B. Winkel, J. Kerp, P. M. W. Kalberla +1
Since autumn 2008 an L-band 7-Feed-Array is operated for astronomical science at the 100-m radio telescope at Effelsberg. This receiver is used to perform an unbiased, fully sample…
High-resolution 21-cm observations of low-column density gas clumps in the Milky Way halo
N. Ben Bekhti, P. Richter, B. Winkel +2
We study the properties of low-column density gas clumps in the halo of the Milky Way based on high-resolution 21-cm observations. Using interferometric data from the WSRT and the…
A population of weak metal-line absorbers surrounding the Milky Way
Philipp Richter, Jane C. Charlton, Alessio P. M. Fangano +2
We report on the detection of a population of weak metal-line absorbers in the halo or nearby intergalactic environment of the Milky Way. Using high-resolution ultraviolet absorpti…
