The soft X - ray spectrum of PG 1211 + 143
The narrow line QSO PG1211+143 has been a focus of recent attempts to understand the soft excess in AGN, while the 2001 XMM-Newton observation of this luminous AGN also provided evidence for a massive and energetic outflow. Here we consider a physical link between the energetic outflow and the variable soft excess.
متن کاملConfirming the high velocity outflow in PG 1211 + 143
An XMM-Newton observation of the bright QSO PG1211+143 was previously reported to show evidence for a massive, energetic outflow, with an outflow velocity of v∼0.1c based on the identification of blue-shifted absorption lines detected in both EPIC and RGS spectra. Subsequently, an order-of-magnitude lower velocity has been claimed from an ion-by-ion model fit to the RGS data. We show here, in a...
متن کاملThe High-velocity Outflow of Pg 1211+143 May Not Be That Fast
We analyze the X-ray spectrum of the quasar PG 1211+143 observed with the CCD and grating spectrometers on board XMM-Newton. Using an ion by ion fitting model we find an outflow component of about 3000 km s−1 that includes absorption lines of K-shell and L-shell ions of the astrophysically abundant elements. We also identify and include in our model broad (FWHM = 6000 km s−1) emission lines fro...
متن کاملAltered expression of chondroitin sulfate proteoglycan in the stroma of human colon carcinoma. Hypomethylation of PG-40 gene correlates with increased PG-40 content and mRNA levels.
The connective tissue stroma of malignant tumors is a newly formed tissue that supports the growth and progression of neoplastic cells. Proteoglycans are intrinsic components of this complex structure and molecular changes in this class of macromolecules can significantly affect behavioral properties of transformed cells. We report that human colon carcinoma contained increased levels of a chon...

Eben Donges Hospital (EDH) is a regional hospital in the Boland/Overberg region of the Western Cape. It serves a diverse community whose economic stability is reliant on the intensive fruit-farming industry. This farming is heavily dependent on organophosphate (OP)-containing insecticides for pest control, often to the detriment of labourers’ health. The combination of accessibility, limited le...
