An X-ray/radio sample of Active Galactic Nuclei

1. What does Active Galactic Nuclei

mean?
The term AGN refers to:
Extreme luminosities (L~1042 ­ 1046 erg s-1) not produced by stars Luminosity comes from a very compact region (nucleus) implies the presence of SMBH The main and more efficient mechanism to produce energy is accretion ACCRETION DISK

2. Classification of AGN
radio loud (powerful jets):
e.g: radio galaxies, quasars, blazars...

radio quiet
radio quiet quasars (RQQs)
Veron `06: MABS < -23

Seyfert
Veron `06: MABS > -23

3. Unification Model
Geometrical effects are important:
Seyfert 1s
Narrow and broad lines

Seyfert 2s
Only narrow lines

Seyfert 2 Seyfert 2

Seyfert 1 Seyfert 1

4. AGN emissions:

Optical/UV band: "big blue bump" Accretion Disk IR band: thermal emission Dust (torus) Radio Jet X-ray Comptonization of disk photons Soft: 0.5-2keV Hard: 2-10keV

Wide spectrum Emission in all bands

5. Advantages of a multiband analysis
Each component has a different origin Better knowledge of the properties of an AGN Main goal of this project: DATA CORRELATION X-ray data (XMM Newton) Radio and optical data (catalogues)

10.Conclusions Search in catalogs for data:
MABS to separate Quasars and Seyfert Radio fluxes looking for correlations FWHM to reclassify in NL and BL

Results:
Good correlation between X-ray/radio
Both emissions related with main parameters of AGN (mass, accretion rate...) Not depends on the object

Large soft excess in NLSY
