On the Effects of Extended-Source Morphology on Emission-Line Redshift Accuracy
نویسنده
چکیده
We discuss the effects of emission-line regions distributed asymmetrically in extended galaxies on redshift estimates. Using published estimates for the distance distribution of line-emitting regions, we present a Monte Carlo simulation and establish that the redshift uncertainty is typically σz/(1+z)∼0.0007. We discuss several options to mitigate this uncertainty, most of which require data taken in multiple orients.

PROBING THE WARM GAS IN HIGH REDSHIFT RADIO GALAXIES New Results on the Alignment Effect
We report on the results of an in depth investigation of the extended [O ii]λ3727 line-emission in 11 3CR radio galaxies (0.5 < z < 1.1). Using a FabryPerot etalon to obtain both the kinematics and morphology of the [O ii] gas, our goal was to find the mechanisms responsible for the creation and excitation of this warm gas, and the source of its alignment with the radio emission.
متن کاملEMISSION-LINE OBJECTS FROM A PRELIMINARY UKST OBJECTIVE PRISM SURVEY
A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...
متن کاملA Detailed Study of the Complex Line - Emission Regions in the Radio Galaxy 3 C 34
We present the results of an extensive Fabry-Perot investigation of the extended line-emission gas surrounding powerful radio galaxies. High spatial (< ∼ 1. ′′ 4) and kinematical (400 km s −1) resolution observations of the [O ii]λ3727 emission-line of the powerful, double radio source 3C 34 (z=0.689) are given. We present evidence that anisotropic radiation emanating from a hidden AGN is respo...
متن کاملXray observations of high redshift radio galaxies
I summarize Xray properties of high redshift radio galaxies, beginning with a brief review of what has been learned from Xray observations of low redshift powerful radio galaxies (in particular, Cygnus A), and then turning to Chandra observations of four high redshift radio galaxies. Hot Xray emitting atmospheres of the type seen in low redshift clusters are not detected in the high redshift so...
متن کامل4 C + 39 . 29 – Extended emission around a powerful Type 2 quasar
We present new X-ray and optical spectroscopy of a Type 2 quasar candidate selected from a follow-up program of hard, optically-dim, serendipitous Chandra sources. The source is confirmed to be a Type 2 quasar at z = 0.536 with an intrinsic 2–10 keV luminosity L 2−10 = 5 × 10 44 h −2 0.7 erg s −1 , an absorbing column density N H = 8 × 10 23 cm −2 and a neutral Fe Kα line detected by XMM-Newton...
