A sensitive submillimetre survey of Broad Absorption Line quasars
Using the SCUBA bolometer array on the JCMT, we have carried out a submillimetre (submm) survey of Broad Absorption Line quasars (BALQs). The sample has been chosen to match, in redshift and optical luminosity, an existing benchmark 850μm sample of radio-quiet quasars, allowing a direct comparison of the submm properties of BAL quasars relative to the parent radio-quiet population. We reach a s...
متن کاملAn XMM-Newton survey of broad iron lines in AGN
We report on the iron Kα line properties of a sample of Seyfert galaxies observed with the XMM-Newton EPIC pn instrument. Using a systematic and uniform analysis, we find that complexity at iron-K is extremely common in the XMMNewton spectra. Once appropriate soft X-ray absorption, narrow 6.4 keV emission and associated Compton reflection are accounted for, ∼ 75 % of the sample show an improvem...
متن کاملA broad survey of recombination in animal mitochondria.
Recombination in mitochondrial DNA (mtDNA) remains a controversial topic. Here we present a survey of 279 animal mtDNA data sets, of which 12 were from asexual species. Using four separate tests, we show that there is widespread evidence of recombination; for one test as many as 14.2% of the data sets reject a model of clonal inheritance and in several data sets, including primates, the recombi...
