Using NASA's Submillimeter Wave Astronomy Satellite (SWAS), we have examined the production of water in quiescent and shocked molecular gas through a survey of the 556.936 GHz 110-101 transition of or...
Radio and Far-Infrared Emission as Tracers of Star Formation and Active Galactic Nuclei in Nearby Cluster Galaxies
AWM7 A426
font style='font-size:12px;'>
2014/12/24
We have studied the radio and far-infrared (FIR) emission from 114 galaxies in the seven nearest clusters (<100 Mpc) with prominent X-ray emission to investigate the impact of the cluster environment ...
A Study of CO Emission in High-Redshift QSOs Using the Owens Valley Millimeter Array
SMM J04135+10277 VCV J140955.5+562827
font style='font-size:12px;'>
2014/12/24
Searches for CO emission in high-redshift objects have traditionally suffered from the accuracy of optically derived redshifts for lack of bandwidth in correlators at radio observatories. This problem...
Simulation of soft X-ray emission lines from the missing baryons
theory diff use radiation large-scale structure of universe
font style='font-size:12px;'>
2014/12/24
We study the soft X-ray emission (0.1-1 keV) from the warm-hot intergalactic medium (WHIM) in a hydrodynamic simulation of a cold dark matter universe. Our main goal is to investigate how such emissio...

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...
The Galactic Central Diffuse X-Ray Enhancement: A Differential Absorption/Emission Analysis
3C 273 Mrk 421
font style='font-size:12px;'>
2014/12/23
The soft X-ray background shows a general enhancement toward the inner region of the Galaxy. But whether this enhancement is a local feature (e.g., a superbubble within a distance of 200 pc) and/or a ...
