[CII] 158μm Emission and Metallicity in PDRs
We study the effects of a metallicity variation on the thermal balance and [CII] fine-structure line strengths in interstellar photon dominated regions (PDRs). We find that a reduction in the dust-to-gas ratio and the abundance of heavy elements in the gas phase changes the heat balance of the gas in PDRs. The surface temperature of PDRs decreases as the metallicity decreases except for high de...
متن کاملStar Formation and Molecular Clouds towards the Galactic Anti-Center
The Galactic Anticenter region hosts a a number of massive molecular cloud complexes, some of which are currently actively forming stars. Two major OB associations, Gem OB1 and Aur OB1, are found in this direction, each with numerous massive stars and a supernova remnant. The dominant region of star formation is centered around the Sh 2-235 complex and the nearby regions AFGL 5142, 5144, and 51...
متن کاملSPH Simulations of Galactic Gaseous Disk with Bar: Distribution and Kinematic Structure of Molecular Clouds toward the Galactic Center
We have performed Smoothed Particle Hydrodynamic (SPH) simulations to study the response of molecular clouds in the Galactic disk to a rotating bar and their subsequent evolution in the Galactic Center (GC) region. The Galactic potential in our models is contributed by three axisymmetric components (massive halo, exponential disk, compact bulge) and a non-axisymmetric bar. These components are ...
متن کاملMACHOs AND MOLECULAR CLOUDS IN GALACTIC HALOS
Recent observations of microlensing events in the Large Magellanic Cloud by the MACHO and EROS collaborations suggest that an important fraction of the galactic halo is in the form of Massive Astrophysical Compact Halo Objects (MACHOs) with mass ∼ 0.1M⊙. We outline a scenario in which dark clusters of MACHOs and molecular clouds form in the halo at galactocentric distances larger than ∼ 10 − 20...
متن کاملHot Molecular Gas in the Galactic Center
Using the new 23 GHz receivers at the Very Large Array (VLA), we have detected NH3(6,6) emission (ν = 25.056025 GHz) from hot (> 150 K) molecular clouds in the central 10 pc of the Galaxy. This is the first successful detection of NH3(6,6) with the VLA. The brightest emission comes from a region interior to the “circumnuclear disk” (CND), less than 1.5 pc in projected distance from Sgr A*. This...
