Broad absorption line quasars have the same cool dust emission as quasars without BALs

چکیده
The results of a sub-millimeter survey of SDSS broad C iv absorption line quasars is discussed. It is found that the sub-millimeter flux distribution of BAL quasars is similar to that of non-BAL quasars. This is consistent with the idea that all quasars contain broad absorption line regions, but only a fraction of them are visible along our line-of-sight. The observations are inconsistent with BAL quasars being observed at a special evolutionary epoch co-inciding with a high star-formation rate and dust mass.

Discovery of Radio-loud Broad Absorption Line Quasars Using Ultraviolet Excess and Deep Radio Selection
We report the discovery of five broad-absorption-line (BAL) QSOs in a complete sample of 111 ultraviolet excess (UVX) QSO candidates also detected in the NRAO VLA Sky Survey. All five BAL QSOs, which include two high-ionization BAL QSOs and three low-ionization BAL QSOs, are formally radio-loud. Of QSOs with z > 0.4, 3±2% show low-ionization BALs, and of QSOs with z > 1.5, all radio-loud, 9±5% ...
متن کاملThe First-2mass Red Quasar Survey Ii: an Anomalously High Fraction of Lobals in Searches for Dust-reddened Quasars
We present results on a survey to find extremely dust-reddened Type-1 Quasars. Combining the FIRST radio survey, the 2MASS Infrared Survey and the Sloan Digital Sky Survey, we have selected a candidate list of 122 potential red quasars. With more than 80% spectroscopically identified objects, well over 50% are classified as dust-reddened Type 1 quasars, whose reddenings (E(B-V)) range from appr...
متن کاملX-ray Insights into the Physics of Mini-bal Quasar Outflows
We examine the UV and X-ray properties of 256 radio-quiet SDSS quasars (QSOs) observed in X-rays with Chandra and/or XMM-Newton in order to study the relationship between QSOs with broad C IV absorption lines (BALs; width > 2000 km s) and those with C IV mini-BALs (here defined to have widths of 1000–2000 km s). Our sample includes 42 BAL and 48 mini-BAL QSOs. The relative X-ray brightness and ...
متن کاملEstimating the continuum of quasars using the articial neural networks
A lot of absorption lines are in the bluewards of Lyα emission line of quasar which is well-known as Lyαforest. Most of absorption lines in this forest belong to the Lyα absorption of the neutral hydrogen in the inter-galactic medium (IGM). For high redshift quasars and in the continuum with low and medium resolution, there are no many regions without absorption, so that, the quasar continuum i...
متن کاملThe Optical/near-ir Colors of Broad Absorption Line Quasars, including the Candidate Radio-loud Bal Quasar J1556+3517
A candidate radio-loud broad absorption line quasar (RLBAL) has been reported by Becker et al. (1997). We present JHK observations of this object and three other radio-detected BALs taken with the new Michigan-Dartmouth-MIT/Ohio State/Aladdin IR Camera (MOSAIC) on the KPNO 4-meter. The candidate RLBAL J1556+3517 has B?K=6.63, redder than all but one or two known z>1 quasars. This strongly sugge...
