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...
The Difference in Narrow Fe KαLine Emission Between Seyfert 1 and Seyfert 2 Galaxies
Narrow Fe KαLine Emission Seyfert 1 Seyfert 2 Galaxies
2011/1/10
We compile a sample of 89 Seyfert galaxies with both [OIV] 25.89 um line luminosities observed by Spitzer IRS and X-ray spectra observed by XMM EPIC. Using [OIV] emission as proxy of AGN intrinsic lum...
Origins of the H, He I, and Ca II Line Emission in Classical T Tauri Stars
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
We perform local excitation calculations to obtain line opacities and emissivity ratios and compare them with observed properties of H, He I, O I, Ca II, and Na I lines to determine the density, tempe...
Significant X-ray Line Emission in the 5-6 keV band of NGC 4051
Significant X-ray 5-6 keV band NGC 4051
2010/3/8
A Suzaku X-ray observation of NGC 4051 taken during 2005 Nov reveals line emission at 5.44 keV in the rest-frame of the galaxy which does not have an obvious origin in known rest-frame atomic transiti...

Near-IR dust and line emission from the central region of Mrk1066: Constraints from Gemini NIFS
Near-IR dust Gemini NIFS line emission
2010/3/8
We present integral field spectroscopy of the inner 350 pc of the Mrk1066 obtained with Gemini NIFS at a spatial resolution of 35 pc. This high spatial resolution allowed us to observe, for the first ...
