The SED of Low-Luminosity AGNs at high-spatial resolution
J. A. Fernández-Ontiveros, M. A. Prieto, J. A. Acosta-Pulido +1
The inner structure of AGNs is expected to change below a certain luminosity limit. The big blue bump, footprint of the accretion disk, is absent for the majority of low-luminosity…
VLT diffraction-limited imaging at 11 and 18 micron of the nearest active galactic nuclei
J. Reunanen, M. A. Prieto, R. Siebenmorgen
Mid-infrared imaging at resolutions of 300 mas of the central kpc region of 13 nearby, well-known active galaxies is presented. The bulk of the mid-IR emission is concentrated on a…
The signature of high velocity gas in the spectra of NGC 4151
M. Contini, S. M. Viegas, M. A. Prieto
The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. HST data has impressively revealed the existence of a large range…
On the relation between the coronal line emission and the IR/X-ray emission in Seyfert galaxies
M. A. Prieto, A. M. Perez Garcia, J. M. Rodriguez Espinosa
The relation between the X-ray, the coronal line and the infrared (IR) emissions in a sample of the brightest known Seyfert galaxies is analysed. A close relationship between the a…
