Deep H i observations of the compact high - velocity cloud HVC 125 + 41 – 207
We present deep H i observations of the compact high-velocity cloud HVC125+41–207 using the 100m Effelsberg telescope. Our goal was in particular to study the warm neutral medium (WNM) in detail. The Effelsberg data reveals a two phase core/halo structure – one component with a velocity width of FWHM ≈ 5 km s (Westerbork data show FWHM ≈ 2 km s, Braun & Burton 2000) and one with FWHM ≈ 18 km s....
متن کاملH i IMAGING OF LGS 3 AND AN APPARENTLY INTERACTING HIGH-VELOCITY CLOUD
We present a map of the area near the Local Group dwarf galaxy LGS 3, centered on an H i cloud ′ ′ 93 # 93 30 away from the galaxy. Previous authors associated this cloud with LGS 3 but relied on observations made with a 36 beam. Our high-resolution (3 .4), wide-field Arecibo observations of the region reveal that the H i cloud is distinct from the galaxy and suggest an interaction between the ...

متن کاملThe Cosmological Significance of High-velocity Cloud Complex H
We have used new and archival infrared and radio observations to search for a dwarf galaxy associated with the high-velocity cloud (HVC) known as Complex H. Complex H is a large (Ω & 400 deg) and probably nearby (d = 27 kpc) HVC whose location in the Galactic plane has hampered previous investigations of its stellar content. The H I mass of the cloud is 2.0 × 10(d/27 kpc) M⊙, making Complex H o...
متن کاملCompact High Velocity Clouds
We summarize the observed properties of the CHVC population, which provide strong evidence for source distances in the range 200– 1000 kpc. At these distances, the population corresponds to strongly dark-matter dominated sub-dwarf galaxies still accreting onto the more massive Local Group systems. Recent searches for faint associated stellar populations have revealed red-giant candidates for wh...
