HVCs, infall and the Galactic Fountain [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractHigh-velocity clouds (HVCs) consist of gas that does not take part in normal Galactic rotation, having velocities deviating by up to 400 km s−1 from those expected from rotation. Over the past five decades, studies have shown they these clouds trace a number of different processes, including the Galactic Fountain, tidal streams, and infall ...

Tracing Slow Winds from T Tauri Stars via Low Velocity Forbidden Line Emission [PDF]

, 2016
Using Keck/HIRES spectra {\Delta}v ~ 7 km/s, we analyze forbidden lines of [O I] 6300 {\AA}, [O I] 5577 {\AA} and [S II] 6731 {\AA} from 33 T Tauri stars covering a range of disk evolutionary stages.

Caught in the Act: A Metal-rich High-velocity Cloud in the Inner Galaxy

The Astrophysical Journal, 2023
We characterize the chemical and physical conditions in an outflowing high-velocity cloud (HVC) in the inner Galaxy. We report a supersolar metallicity of [O/H] = +0.36 ± 0.12 for the HVC at v _LSR = 125.6 km s ^−1 toward the star HD 156359 ( l = 328.°7,

Properties and Origin of the High-Velocity Gas Toward the Large Magellanic Cloud

, 2009
In the spectra of 139 early-type Large Magellanic Cloud (LMC) stars observed with FUSE and with deep radio Parkes HI 21-cm observations along those stars, we search for and analyze the absorption and emission from high-velocity gas at ...

A circular model for song motor control in Serinus canaria [PDF]

, 2015
Song production in songbirds is controlled by a network of nuclei distributed across several brain regions, which drives respiratory and vocal motor systems to generate sound.

Infall of HVC's and the Origin of HI Supershells [PDF]

Symposium - International Astronomical Union, 1991
Surveys for atomic hydrogen at very high velocities (|V| ≥ 140 km s–1) in the galactic center and anticenter regions of the sky reveal a net inflow of gas toward the Milky Way. In the anticenter, the collisions of infalling clouds with galactic material trigger the most energetic structural disturbance in the Galaxy, the “anticenter supershell”.

Highly Ionized Envelopes of High Velocity Clouds

, 2009
We present recent results on highly ionized gas in Galactic High-Velocity Clouds (HVCs), originally surveyed in OVI (Sembach et al. 2003). In a new FUSE/HST survey of SiII/III/IV (Shull et al.

FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) 2: Possible evidence for formation of NGC~6618 cluster in M17 by cloud-cloud collision

, 2017
We present $^{12}$CO $J=$1--0, $^{13}$CO $J=$1--0 and C$^{18}$O $J=$1--0 images of the M17 giant molecular clouds obtained as part of FUGIN (FOREST Ultra-wide Galactic Plane Survey InNobeyama) project. The observations cover the entire area of M17 SW and

Songbird organotypic culture as an in vitro model for interrogating sparse sequencing networks [PDF]

, 2017
Sparse sequences of neuronal activity are fundamental features of neural circuit computation; however, the underlying homeostatic mechanisms remain poorly understood. To approach these questions, we have developed a method for cellular-resolution imaging

Teaching High-Value Care: Case Vignettes for Pediatric Practice

MedEdPORTAL, 2018
Introduction As health care systems recognize the importance of high-value care (HVC), physicians must focus on individualized patient outcomes using economically responsible and evidence-based medicine.
