High-Resolution Imaging of Molecular Line Emission from High-Redshift QSOs
starburst evolution radio lines
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 Study of CO Emission in High-Redshift QSOs Using the Owens Valley Millimeter Array
SMM J04135+10277 VCV J140955.5+562827
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...

Despite decades of study, it remains unclear whether there are distinct radio-loud and radio-quiet populations of quasi-stellar objects (QSOs). Early studies were limited by inhomogeneous QSO samples,...
Disk, merger, or outflow ? Molecular gas kinematics in two powerful obscured QSOs at z>3.4

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...

A correlation between redshifts .z/ and apparent magnitudes
.V / (Hubble relation) of Quasi Stellar Objects (QSOs) has long been
sought. Such a correlation exists for galaxies whose redshifts are of...
