Active Galaxy Unification
نویسنده
چکیده
Most bright galaxies are spirals, like our own, and in the nearby well-studied cases they reveal the beautiful and intricate grand-design spiral patterns that are both familiar and appealing (e.g., Sandage & Tammann 1981). At the centre of a few out of every hundred spirals there is also an extremely bright point of light. This point can be so bright that it can outshine the entire stellar output of the disc and bulge of the galaxy, and this enormous luminosity is produced from an exceedingly small volume indeed. This thesis studies aspects of these active galactic nuclei (AGNs) that inhabit some spiral galaxies.

Seyfert Galaxies: Nuclear Radio Structure and Unification
We have observed a sample of Seyfert (Sy) galaxies with the global Very Long Baseline Interferometry (VLBI) to test the predictions of the unification scheme for the Sy galaxies which hypothesises that Sys of Type 1 and of Type 2 constitute a single population of objects. If Sy 1 and Sy 2 galaxies differ only in the orientation of the axisymmmetric active nucleus with respect to the observer, t...
متن کاملChandra Observations of Ngc 4698: a Seyfert 2 Galaxy with No Absorption
We present Chandra ACIS-S observations of the enigmatic Seyfert 2 galaxy NGC 4698. This object, together with several other bona fide Seyfert 2 galaxies, shows no absorption in the low spatial resolution ASCA data, in contrast to the standard unification models. Our Chandra observations of NGC 4698 probe directly the nucleus, allowing us to check whether nearby sources contaminate the ASCA spec...
متن کاملThe Starburst-AGN connection: Implications for the Unification of Seyferts
Observations at ultraviolet, optical and near-infrared wavelengths have shown the existence of recent star formation in the nuclear regions of Seyfert 2 (Sy2) galaxies that suggest a connection between the Starburst and the Seyfert phenomenon. According with the standard unified models of AGN circumnuclear starbursts also have to be present (and in the same numbers) in Sy1 as in Sy2 galaxies. T...
متن کاملOrigin of the X-ray Background and Agn Unification: New Perspectives
We critically review the basic assumptions of the standard model for the synthesis of the XRB in the light of new data from ultradeep surveys by Chandra and XMM, resolving major parts of it. Important constraints come in particular from the observed redshift distributions of faint hard X-ray sources – showing large excesses at redshifts (z ∼ 0.8) much lower than expected by the synthesis models...

baryonic matter distribution in the large-scale structures is one of the main questions in cosmology. This distribution can provide valuable information regarding the processes of galaxy formation and evolution. On the other hand, the missing baryon problem is still under debate. One of the most important cosmological structures for studying the rate and the distribution of the baryons is gal...
