X-ray spectral variability of LINERs selected from the Palomar sample
L. Hernández-García, O. González-Martín, J. Masegosa +1
Variability is a general property of active galactic nuclei (AGN). At X-rays, the way in which these changes occur is not yet clear. In the particular case of low ionisation nuclea…
Active galactic nuclei synapses: X-ray versus optical classifications using artificial neural networks
O. Gonzalez-Martin, D. Diaz-Gonzalez, J. A. Acosta-Pulido +5
(Abridged) Many classes of active galactic nuclei (AGN) have been defined entirely throughout optical wavelengths while the X-ray spectra have been very useful to investigate their…
ALMA reveals the feeding of the Seyfert 1 nucleus in NGC 1566
F. Combes, S. Garcia-Burillo, V. Casasola +9
We report ALMA observations of CO(3-2) emission in the Seyfert 1 galaxy NGC 1566, at a spatial resolution of 25 pc. Our aim is to investigate the morphology and dynamics of the gas…
