Spectral optical monitoring of a double-peaked emission line AGN Arp 102B: I. Variability of spectral lines and continuum
A. I. Shapovalova, L. C. Popovic, A. N. Burenkov +14
Here we present results of the long-term (1987-2010) optical spectral monitoring of the broad line radio galaxy Arp 102B, a prototype of active galactic nuclei with the double-peak…
A Multiwavelength Cross-Correlation Variability Study of Fermi-LAT Blazars
V. Patiño-Álvarez, A. Carramiñana, L. Carrasco +1
We carried out a multiwavelength cross-correlation analysis of a sample of 16 blazars detected by Fermi/LAT. The purpose is to investigate if there exists correlations between the…
Optical Spectrophotometric Monitoring of Fermi/LAT Bright Sources
V. Patiño-Álvarez, V. Chavushyan, J. León-Tavares +4
We describe an ongoing optical spectrophotometric monitoring program of a sample of Fermi/LAT bright sources showing prominent and variable γ-ray emission, with the 2.1m telescope…
Flare-like variability of the Mg IIλ2800Å emission line in the gamma-ray blazar 3C 454.3
J. León-Tavares, V. Chavushyan, V. Patiño-Álvarez +9
We report the detection of a statistically significant flare-like event in the Mg IIλ2800Å emission line of 3C 454.3 during the outburst of autumn 2010. The highest levels of emiss…
