Spectroscopic measurements of emission line ratios and velocities are presented for ionized gas across the central plane of NGC 55, a late-type galaxy in the Sculptor group. The low metallicity in NGC 55 leads to relatively low line ratios of [S ii]/Hα and [N ii]/Hα for H ii regions as well as the diffuse ionized gas. These are the first spectroscopical measurements of line ratios in ionized ga...
The Owens Valley Radio Observatory (OVRO) millimeter array was used to make observations of the CS(2-1) line (at 97.981 GHz) arising from the G0.07+0.04 region of the “−30 km s−1” molecular cloud near the Galactic center with a spatial resolution of ∼8. The ionized edges of this cloud forms the Arched Filament HII regions which are ionized by the adjacent hes stellar cluster. The OVRO data were...
Context. Whether high mass stars continue to accrete material beyond the formation of an HII region is still an open question. Ionized infall and outflow have been seen in some sources, but their ties to the surrounding molecular gas are not well constrained. Aims: We aim to quantify the ionized and molecular gas dynamics in a high mass star forming region (K3-50A) and their interaction. Method...
Background: Blood gas analysis (BGA), including measurement of ionized calcium, is performed routinely in patients with end stage renal disease on renal replacement therapy, especially when using citrate for regional anticoagulation. After installation of a new blood gas analyzer (RAPIDpoint 405; BGA), we observed lower ionized calcium concentrations in a few patients without signs of hypocalce...
We present Australia Telescope Compact Array (ATCA) H I imaging of the edge-on galaxy NGC 1596, which was recently found to have counter-rotating ionized gas in its center (< 15). We find a large H I envelope associated with a nearby companion, the dwarf irregular galaxy NGC 1602. The H I covers a region ≈ 11.9×13.4 (62×70 kpc) and the total H I mass detected is 2.5±0.1× 10 M⊙ (assuming an 18 M...
We present interstellar absorption-line measurements of the ions S III and Al III toward the stars b1 Sco, k Col, m Per, f Oph, o Leo, and HD 18100 using archival data from the Goddard High-Resolution Spectrograph on board the Hubble Space T elescope. The ions Al III and S III trace heavily depleted and nondepleted elements, respectively, in ionized gas along the sight lines to these late-O/ear...
We present the kinematics and photometry of the stars and of the ionized gas near the centre of the S0 galaxy NGC4036. Dynamical models based on the Jeans Equation have been constructed from the stellar data to determine the gravitational potential in which the ionized gas is expected to orbit. Inside 10 ′′ , the observed gas rotation curve falls well short of the predicted circular velocity. O...
