Di Teodoro, Enrico Maria; McClure-Griffiths, Naomi; Lockman, Felix J.; Denbo, Sara R.; Endsley, Ryan; Ford, H. Alyson; Harrington, Kevin


We present the results of a new sensitive survey of neutral hydrogen above and below the Galactic Center with the Green Bank Telescope. The observations extend up to Galactic latitude |b| < 10° with an effective angular resolution of 9′.5 and an average rms brightness temperature noise of 40 mK in a 1 km s-1 channel. The survey reveals the existence of a population of anomalous high-velocity clouds extending up to heights of about 1.5 kpc from the Galactic plane and showing no signature of...[Show more]
