Empirical Formulae for Electron Density Diagnostics from Hα and Hβ Line Profiles
We present empirical formulae for the electron density vs. line profile widths and shifts developed from precise measurements of hydrogen Balmer series alpha and beta emissions for diagnostics of laser-induced plasma. The formulae are for the Stark width and Stark red shift of the Hα line, as well as for the Stark width and peak separation of the Hβ line and are tested using measurements of Hα ...
متن کاملIntensity Mapping of H α , H β , O II [ ] , and O III [ ] Lines at z < 5
Intensity mapping is becoming a useful tool to study the large-scale structure of the universe through spatial variations in the integrated emission from galaxies and the intergalactic medium. We study intensity mapping of the a H 6563 Å, [O III] 5007Å, [O II] 3727Å, and b H 4861 Å lines at z 0.8 5.2. The mean intensities of these four emission lines are estimated using the observed luminos...
متن کاملSpectropolarimetry of Broad Hα Lines and Geometry of the BLR
In a small fraction of Broad Line Radio Galaxies (BLRG) and Seyfert 1 galaxies, the polarization position angle rotates across the broad emission lines, especially at Hα. An understanding of this behavior can potentially yield important information on the scattering geometry in the nucleus. We show two examples of this phenomenon, 3C 445, a BLRG, and Mrk 231, a Seyfert 1, and present an equator...

Intensity mapping is now becoming a useful tool to study the large-scale structure of the universe through spatial variations in the integrated emission from galaxies and the intergalactic medium. We study intensity mapping of the Hα 6563Å, [OIII] 5007Å, [OII] 3727Å and Hβ 4861Å lines at 0.8 ≤ z ≤ 5.2. The mean intensities of these four emission lines are estimated using the observed luminosity...
