A population of high-velocity absorption-line systems residing in the Local Group
Sietske J. D. Bouma, Philipp Richter, Cora Fechner
Aims. We aim to investigate the ionisation conditions and distances of Galactic high-velocity clouds (HVCs) in the Galactic halo and beyond in the direction of the Local Group (LG)…
Circumgalactic gas at its extreme: tidal gas streams around the Whale galaxy NGC 4631 explored with HST/COS
P. Richter, B. Winkel, B. P. Wakker +8
We present a detailed analysis of the absorption properties of one of the tidal gas streams around the Whale galaxy NGC4631 in the direction of the quasar 2MASSJ12421031+3214268. O…
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…
An HST/COS legacy survey of intervening SiIII absorption in the extended gaseous halos of low-redshift galaxies
P. Richter, B. P. Wakker, C. Fechner +3
Doubly ionized silicon (SiIII) is a powerful tracer of diffuse ionized gas inside and outside of galaxies. It can be observed in the local Universe in ultraviolet (UV) absorption a…
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…
High-resolution observations of two OVI absorbers at z=2 towards PKS 1448-232
N. Draganova, P. Richter, C. Fechner
To explore the ionization conditions in highly-ionized absorbers at high redshift we have studied in detail two intervening OVI absorbers at z=2 towards the quasar PKS1448-232, bas…
