We report the first determination of a distance bracket for the high-velocity cloud (HVC) complex C. Combined with previous measurements showing that this cloud has a metallicity of 0.15 times solar, these results provide ample evidence that complex

We present observations of the (field of the) Seyfert galaxy Mark290, which probes the high-velocity cloud (HVC) complex C, one of the largest HVCs. We find that this object has a metallicity of 0.094pm0.020(+0.022-0.019) times solar. We determine a

A full understanding of the High Velocity Clouds (HVCs) is still lacking more than four decades after their discovery. Determining the clouds' locations in relation to the Galaxy is an important constraint on hierarchical assembly models of galaxies

This paper presents results of a program to derive distances of high-velocity clouds (HVCs) through measurement of absorption in the CaIIH and K lines. The problems of the method and their solutions are discussed in detail. A probable detection of ab

Table 1 summarizes results of programs to determine distances and metallicities of high-velocity clouds (HVCs, see Wakker 1991, IAU Symp 144, 27 for a general review). Reliable absorption is reported for one stellar probe (BD+38 2182), giving a dista

High-velocity clouds (HVCs) are HI clouds deviating strongly from the general Galactic rotation. Their distances, and hence origins, have long remained unknown. However, three major complexes are now known to lie at z > 1 kpc, while two smaller cloud
