High-Resolution Imaging of Molecular Line Emission from High-Redshift QSOs
starburst evolution radio lines
font style='font-size:12px;'>
2014/12/26
We present moderate- (1'') and high-resolution (02) observations of the CO (2–1) emission at 43 GHz and radio continuum emission at 1.47 GHz from the z = 4.7 QSO BRI 1202-0725 and the z = 4.4 QSO BRI ...
A Detection of [C II] Line Emission in the z = 4.7 QSO BR 1202–0725

font style='font-size:12px;'>
2014/12/23
We present ~3'' resolution imaging of the z = 4.7 QSO BR 1202-0725 at 900 μm from the Submillimeter Array. The two submillimeter continuum components are clearly resolved from each other, and the posi...

2014/12/9
We present the results of a comparison of new millimeter and submillimeter molecular line survey of bright-rimmed clouds, observed at FCRAO in the CO (J = 1 → 0), C18O (J = 1 → 0), HCO+ (J = 1 → 0), H...
Variability of the SiO thermal line emission toward the young L1448-mm outflow
Variability SiO emission L1448-mm outflow
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...
Measurements of nuclear $\gamma$-ray line emission in interactions of protons and $\alpha$ particles with N, O, Ne and Si
Measurements of nuclear $\gamma$-ray line emission interactions of protons $\alpha$ particles with N, O, Ne and Si
font style='font-size:12px;'>
2011/1/4
$\gamma$-ray production cross sections have been measured in proton irradiations of N, Ne and Si and $\alpha$-particle irradiations of N and Ne. In the same experiment we extracted also line shapes fo...
Origins of the H, He I, and Ca II Line Emission in Classical T Tauri Stars
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...

VUV Spectral Line Emission Measurements in the TCABR Tokamak
VUV spectrometry higher diffraction order spectra tokamak ion temperature multi-channel detector
font style='font-size:12px;'>
2010/7/5
The study of tokamak plasma light emissions in the vacuum ultraviolet (VUV) region is an important subject since many impurity spectral emissions are present in this region. These spectral emissions c...

Near-IR dust and line emission from the central region of Mrk1066: Constraints from Gemini NIFS
Near-IR dust Gemini NIFS line emission
font style='font-size:12px;'>
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 ...
