Detection of helicoidal motion in the optical jet of PKS 0521-365
E. F. Jiménez-Andrade, V. Chavushyan, J. León-Tavares +5
The jet activity of Active Galactic Nuclei (AGN), and its interaction with the interstellar medium (ISM), may play a pivotal role in the processes which regulate the growth and sta…
The nature of fifty Palermo Swift-BAT hard X-ray objects through optical spectroscopy
A. F. Rojas, N. Masetti, D. Minniti +16
We present the nature of 50 hard X-ray emitting objects unveiled through an optical spectroscopy campaign performed at seven telescopes in the northern and southern hemispheres. Th…
Long-term optical spectral monitoring of NGC 7469
Alla I. Shapovalova, L. C. Popović, V. H. Chavushyan +11
We present the results of the long-term (20-year period, from 1996 to 2015) optical spectral monitoring of the Seyfert 1 galaxy NGC 7469. The variation in the light-curves of the b…
