A Multi-Wavelength Study of the Nature of Type 1.8/1.9 Seyfert Galaxies
M. L. Trippe, D. M. Crenshaw, R. P. Deo +4
We focus on determining the underlying physical cause of a Seyfert galaxy's appearance as type a 1.8 or 1.9. Are these "intermediate" Seyfert types typical Seyfert 1 nuclei with re…
A New Radio Loudness Diagnostic for Active Galaxies: a Radio-To-Mid-Infrared Parameter
M. Meléndez, S. B. Kraemer, H. R. Schmitt
We have studied the relationship between the nuclear (high-resolution) radio emission, at 8.4 GHz (3.6 cm) and 1.4 GHz (20 cm), the [O IV] 25.89um, [Ne III] 15.56um and [Ne II] 12.…
Spectral variability and reverberation time delays in the Suzaku X-ray spectrum of NGC 4051
L. Miller, T. J. Turner, J. N. Reeves +3
Long-exposure Suzaku X-ray observations of the active galaxy NGC 4051 from 2005 and 2008 are analysed, in an attempt to reach a self-consistent understanding of the spectral variab…
