Active Galactic Nucleus Emission-line Properties versus the Eddington Ratio
We analyze UV spectra for a large sample of 578 type 1 active galactic nuclei and derive Eddington ratios, L=LEdd, from the bolometric luminosities and emission-line widths for each object in the sample. The sample spans 5 orders of magnitude in supermassive black hole (SMBH) mass, 7 orders of magnitude in luminosity, and a redshift range 0 z 5. We include a sample of 26 low-redshift narrow-lin...
متن کاملActive Galactic Nuclei Emission-line Properties versus Eddington Ratio
We analyze UV spectra for a large sample of 578 Type 1 Active Galactic Nuclei and derive Eddington ratios, L/Ledd, from the bolometric luminosities and emission line widths for each object in the sample. The sample spans five orders of magnitude in supermassive black hole (SMBH) mass, seven orders of magnitude in luminosity, and a redshift range from 0 ≤ z ≤ 5. We include a sample of 26 lowreds...
متن کاملSoftware for the Analysis of Emission Line Nebulae
A set of software tools has been developed for the IRAF/STSDAS environment to derive the physical conditions in a low-density (nebular) gas given appropriate diagnostic emission line ratios; and line emissivities given appropriate emission line uxes, the electron temperature (T e) and density (N e). The package is based on the ve-level atom program developed by De Robertis, Dufour and Hunt (198...
متن کاملDetection of Ultraweak Photon Emission (UPE) from Cells as a Tool for Pathological Studies
Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...
متن کاملEmission Reduction Strategies for Small Single Cylinder Diesel Engine Using Valve Timing and Swirl Ratio
Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...
