	active galactic nucleus (AGN)
		AGN are found at the heart of active galaxies, including quasars, Seyfert galaxies, blazars, and radio galaxies.
		Since a fl hole, by definition, emits nothing, the radiation from an AGN is believed to come from material heated to several million degrees in an accretion disk before tumbling into the fl hole or, in some cases, being shot away in twin jets along the central engine’s spin axis.
		Within each is a broad range of luminosity, from AGN so weak that they are barely detectable against the light from the central stars of their host galaxy to quasars that are more than 100 times brighter than all the stars in their hosts put together.

		In this model, the different forms of AGNs we observe are merely different views of this process from different orientations with respect to the axis of the jet and the accretion disk.
		AGN variability consists of slow irregular fluctuations upon which are superimposed occasional outbursts and declines.
		A more extended description of AGN Variability is available which includes illustrations of various types of lightcurves plus recommendations for the type of photometric data that can be most helpful in improving our understanding of the AGN phenomenon.

		AGN which have about the same luminosity than the host galaxy are called Seyfert galaxies.
		AGN have the peculiarity to emit electro-magnetic radiation over a very broad spectral domain from the infrared to the X-rays.
		To explain the different spectral components of an AGN, it is necessary to refer to many different physical emission processes (synchrotron emission in the radio, inverse comptonization in the X-rays, thermal dust emission in the infrared).

	Beginner's Guide to AGN
		So, at the most basic level, AGNs are simply the cores of galaxies that are not quiescent like normal galaxy cores: for instance, some of them emit an amount of energy comparable to the output of an entire galaxy from their cores, which are regions measuring only parsecs in size.
		Certainly the occurance of AGNs depends on pulling gas from the outer, kpc-scale regions of the disk to the inner regions, but it's not at all clear how this is done (see astro-ph/0407068 and astro-ph/0408282 for very nice overviews).
		Below are the various classes of AGNs that are often seen in the literature with a brief explanation of where they fit in.

	MAST AGN Catalog
		The Active Galactic Nuclei (AGN) catalog is heavily based on A Catalogue of Quasars and Active Nuclei (7th Edition), ESO Scientific Report No. 17, by Véron-Cetty & Véron (1996) [VV96].
		Therefore, for objects without (B-V) colors, V magnitudes have been derived from the given values by subtracting (B-V) values typical of the class to which an object belongs to, unless the reference was to a paper which gave V magnitudes directly.
		One should remember that most AGN are variable so the reported V magnitudes should be taken only as indicative.

	AGN Report
		It was stressed that the AGN is responsible to and is a structural component of the SCN.
		The AGN members found that while there was often considerable coordination and cooperation, it was on an ad hoc basis, and worked best in acute emergency situations.
		The AGN were cautioned not to take too superficial a view of country-level coordination since bilaterals and NGOs, important actors in some countries, do not fall within the UN Resident Coordinator system.

		AGN International Middle and Near East Conference opened in Dubai on 10th December 2002 and ran for two days.
		The conference emphasized on the large opportunities that are opening up for accounting firms especially after the recent scandals in the U.S. and great potentials in the areas like providing quality audits to clients and looking at non-audit services.
		He said that AGN has now presence in 76 countries and a billing of Euro 1.1 billion in 2002.

		The AGN was involved in the development of many of the SCN symposia and almost all of the special workshops which led to a substantial proportion of the publications that have brought much credit to the SCN albeit sometimes with discomfort to individual UN agencies.
		As chair of the AGN for the past two years, I do not see "holding the AGN in abeyance" as a sign of failure but rather agree with the need to re-examine its role.
		The main strength of the AGN concept past, present, and future, is that it brings independent periodic review of the work of the UN system in food and nutrition.

	AGN & the Amateur
		While AGN remain exotic objects and the majority are only detectable with the largest telescopes and most sophisticated equipment, a few of the brighter ones are accessible to the amateur observer, and the contribution of the dedicated amateur can be of a significant benefit to the professional astronomer.
		In favour of a visual approach is the ability to observe several objects in the session; the results are rapidly obtained and the equipment is relatively inexpensive, although realistically a larger aperture is needed for such faint objects.
		While the numbers of AGN available are limited, there are still over a dozen to be observed by the owners of a 40cm or larger telescope.

		Single SED composites of local "warm" Type 1 and "cooler" Type 2 AGN from the far to near-IR are assumed for the unobscured and obscured objects respectively, independent of luminosity.
		The counts of ULIRGs appear to be less than those of AGN at 24µm due to the large difference in their SED shapes at short wavelengths.
		The flatter redshift distrbution observed for AGN reflects the presence of numerous low-luminosity sources which are only detectable at the lowest redshifts.

		Although we are calling this "AGN Physics with the SDSS", by no means is it required that the talks/posters be based upon SDSS data or even mention the SDSS in any way.
		Participation is limited to those that are active in AGN research and will primarily be by invitation, but we have reserved some slots for at-large applications.

	Active Galactic Nuclei
		Quasars are very distant AGN - the most distant quasars mark an epoch when the universe was less than a billion years old and a sixth of its current size.
		In some cases, the size of the AGN is smaller than the size of our solar system.
		Based on X-ray (and other) observations, a good guess is that the power source in AGN is a supermassive fl hole.

		Perhaps the most popularly known instance of AGN are "quasars" which are AGN that are very distant, up to 60 billion light years away.
		Based on X-ray, radio, and other observations, a good guess is that the power source in AGN is a supermassive flhole.
		Many AGN also show evidence for a huge torus of gas around the flhole.

	AGN
		Active galactic nuclei (AGN) are galaxies that have very energetic central regions, due to either the presence of a fl hole or star formation activity at the core of the galaxy.
		Three main types of AGN are quasars, ("quasi-stellar objects" or QSOs), which are very compact objects that resemble stars in optical images; Seyfert galaxies, characterized by fluctuations in brightness at their cores; and radio galaxies, which emit massive jets of gas powered by fl holes at their cores.
		Other images of AGN can be found in the VLBA 2cm Survey of Compact Radio Sources and the Jodrell Bank Atlas of DRAGNs.

	Active Galaxies
		In ~10% of the AGN, the MBH + accretion disk somehow produce narrow beams of energetic particles and magnetic fields, and eject them outward in opposite directions away from the disk.
		Radio galaxies, quasars, and blazars are AGN with strong jets, which can travel outward into large regions of intergalactic space.
		Active Galactic Nuclei observed at high (>100 MeV) energies form a subclass known as blazars; a blazar is believed to be an AGN which has one of its relativistic jets pointed toward the Earth so that the emission we observe is dominated by phenomena occurring in the jet region.

	High Energy Astrophysics at Penn State : Active Galactic Nucleii ( AGN )
		Members of the Penn State X-ray Astronomy group are involved in both X-ray and optical studies of the supermassive fl holes that reside in the nuclei of active galaxies.
		These AGN may be a small but distinct subclass which show broad optical line emission from an accretion disk.
		This originates when a jet from an AGN is fired nearly along our line of sight.
