Tests of a Structure for Quasars

نویسنده

  • Martin Elvis
چکیده

The model I recently proposed for the structure of quasars unifies all the emission, absorption and reflection phenomenology of quasars and AGN, and so is heavily overconstrained and readily tested. Here I concentrate on how the model has performed against tests since publication with many of the tests being reported at this meeting. I then begin to explore how these and future tests can discriminate between this wind model and 3 well-defined alternatives.

Estimating the continuum of quasars using the articial neural networks

A lot of absorption lines are in the bluewards of Lyα emission line of quasar which is well-known as Lyαforest. Most of absorption lines in this forest belong to the Lyα absorption of the neutral hydrogen in the inter-galactic medium (IGM). For high redshift quasars and in the continuum with low and medium resolution, there are no many regions without absorption, so that, the quasar continuum i...

Experimental Study on Using Uniform Tuned Liquid Column Damper for Structural Control of Buildings Resting on Loose Soil

In this study, through series of shaking table tests and statistical analysis, the efficiency of Uniform Tuned Liquid Column Damper (UTLCD) in structures resting on loose soils, considering soil-structure interaction was investigated. The soil beneath the structure is loose sandy soil. The Laminar Shear Box (LSB) as a soil container was adopted and the scaled form of the prototype structure nam...

Quasars and Large Scale Structure of the Universe

The majority of bright distant quasars ( 1) may form in massive mergers appearing in compact galaxy groups in/and young clusters. The expected tests are (i) large correlation signal for mediumQSOs (1 2) and (ii) direct search for quasar groups (QGs) indicating positions of distant pre-superclusters which later will evolve to the "systems" like the local Great Attractor or Shapley concentration....

Type 1 Agn Unification

The model I recently proposed for the structure of quasars offers to unify the many aspects of Type 1 AGN: emission lines, absorption lines and reflection features. This makes the model heavily overcon-strained by observation and readily tested. Here I first outline the model, and then concentrate on how the model answers objections raised since publication-with many of the tests being reported...

A Possible Bias Model for Quasars

We propose that the majority of quasars at redshift z ∼ 1 − 5 formed in the environment of new born collapsed halos with 1-D velocity dispersion σ1d v ∼ 400 km s−1. The harboring coefficient f of quasars per halo and the lifetime of quasars depend only on local process, not modulated by the density inhomogeneities on scales larger than the size of the halos. Thus, the bias of quasars on scale l...
