Dense Ionized and Neutral Gas Surrounding Sgr A
We present high resolution H41 hydrogen recombination line observations of the 1 2 (3 pc) region surrounding Sagittarius A (Sgr A ) at 92 GHz using the Millimeter Array at the Owens Valley Radio Observatory (OVRO) with an angular resolution of 7 3 and velocity resolution of 13 km s−1. New observations of H31 , H35 , H41 and H44 lines were obtained using the NRAO 12-m telescope, and their relati...
متن کاملDynamics of Ionized Gas at the Galactic Center: Very Large Array Observations of the Three-Dimensional Velocity Field and Location of the Ionized Streams in Sagittarius A West
We present new results based on high-resolution observations of Sgr A West at the Galactic center with the Very Large Array (VLA) at 1.3 cm. By combining recent observations with those made at earlier epochs with the VLA at wavelengths of 1.3 and 3.6 cm, we measured proper motions for 71 compact HII components in the central 80 (3 pc, assuming D = 8 pc). Using VLA archival data for the H92α rad...

متن کاملIonized nebulae surrounding brightest cluster galaxies
We present integral field spectroscopic observations of six emission-line nebulae that surround the central galaxy of cool core clusters. Qualitatively similar nebulae are observed in cool core clusters even when the dynamics and possibly formation and excitation source are different. Evidence for a nearby secondary galaxy disturbing a nebula, as well as AGN and starburst driven outflows are pr...
متن کاملThermodynamic properties of the ionized gas 3He
In this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3He atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. To perform the calculations, we have considered the kinetic term, and Coulomb interaction between the particles in our Hamiltonian. The calculated properties are free ener...
