Discovery of a Molecular Outflow in the Haro 6-10 Star-forming Region
clouds jets and outfl ows
2014/12/23
We present high sensitivity 12CO and 13CO J=1!0 molecular line maps covering the full extent of the parsec scale Haro 6-10 Herbig-Haro (HH) flow. We report the discovery of a molecular CO outflow alon...
Based on new and archival Chandra observations of the Sombrero galaxy (M 104 = NGC 4594), we study the X-ray emission from its nucleus and the extended X-ray emission in and around its massive stellar...
The JCMT Nearby Galaxies Legacy Survey – V. The CO(J= 3–2) distribution and molecular outflow in NGC 4631
galaxy star
2014/12/20
We have made the first map of CO(J= 3–2) emission covering the disc of the edge-on galaxy, NGC 4631, which is known for its spectacular gaseous halo. The strongest emission, which we model with a Gaus...
One-micron spectroscopic studies of accretion and outflow in T Tauri stars
High resolution spectrum Classical T Taurus Stars Spectrum Air calibrator The stars
2014/12/9
High-resolution spectroscopy of classical T Tauri stars (CTTS) at one micron yields new insight into the interaction of accretion disks, outflowing gas, and the central stars. Eighty-one 0.95–1.12 μm ...

Clustered Star Formation in Magnetic Clouds: Properties of Dense Cores Formed in Outflow-Driven Turbulence
Magnetic Clouds: Properties Dense Cores Formed Outflow-Driven Turbulence
2011/10/11
We investigate the physical properties of dense cores formed in turbulent, magnetized, parsec-scale clumps of molecular clouds, using three-dimensional numerical simulations that include protostellar ...
Short Gamma-ray Bursts: the mass of the accretion disk and the initial radius of the outflow
Short Gamma-ray Bursts:accretion disk initial radius outflow
2011/10/9
In this work we estimate the accretion-disk mass in the specific scenario of binary-neutron-star-merger with current observational data. Assuming that the outflows of short Gamma-ray Bursts (GRBs) are...
Disk, merger, or outflow ? Molecular gas kinematics in two powerful obscured QSOs at z>3.4
Galaxies: high-redshift – Submillimeter: ISM – Submillimeter: galaxies – (Galaxies:) quasars: individual
2011/10/8
We report on the detection of bright CO(4-3) line emission in two powerful, obscured quasars discovered in the SWIRE survey, SW022513 and SW022550 at z>3.4. We analyze the line strength and profile to...
Variability of the SiO thermal line emission toward the young L1448-mm outflow
Variability SiO emission L1448-mm outflow
2011/10/8
The detection of narrow SiO thermal emission toward young outflows has been proposed to be a signature of the magnetic precursor of C-shocks. Recent modeling of the SiO emission across C-shocks predic...
Outflow activities in the young high-mass stellar object G23.44-0.18

2011/9/29
We present an observational study towards the young high-mass star forming region G23.44-0.18 using the Submillimeter Array. Two massive, radio-quiet dusty cores MM1 and MM2 are observed in 1.3 mm con...
