2014/12/24
With a high spatial resolution imaging instrument such as the Chandra ACIS, one can confidently identify an X-ray source with only a few detected counts. The detection threshold of such sources, howev...
Warm-hot gas in and around the Milky Way: Detection and implications of OVII absorption toward LMC X-3
LMC X–3 ISM
font style='font-size:12px;'>
2014/12/24
X-ray absorption lines of highly ionized species such as O VII at about zero redshift have been firmly detected in the spectra of several active galactic nuclei. However, the location of the absorbing...
Chandra Detection of Fe XVII in Absorption: Iron Abundance in the Hot Gaseous Interstellar Medium
4U 1820–303 abundances
font style='font-size:12px;'>
2014/12/24
The iron depletion level and the gas-phase iron abundance in the hot (~106 K) interstellar medium (ISM) are critical to our understanding of its energy balance as well as the thermal sputtering, cooli...
A Detection of [C II] Line Emission in the z = 4.7 QSO BR 1202–0725
high redshift submillimeter,
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...
