Locating the gamma-ray emission site in Fermi/LAT blazars from correlation analysis between 37 GHz radio and gamma-ray light curves
V. Ramakrishnan, T. Hovatta, E. Nieppola +3
We address the highly debated issue of constraining the gamma-ray emission region in blazars from cross-correlation analysis using discrete correlation function between radio and g…
The link between broad emission line fluctuations and non-thermal emission from the inner AGN jet
J. León-Tavares, V. Chavushyan, A. Lobanov +2
AGN reverberate when the broad emission lines respond to changes of the ionizing thermal continuum emission. Reverberation measurements have been commonly used to estimate the size…
The connection between the parsec-scale radio jet and gamma-ray flares in the blazar 1156+295
Venkatessh Ramakrishnan, Jonathan León-Tavares, Elizaveta A. Rastorgueva-Foi +30
The blazar 1156+295 was active at gamma-ray energies, exhibiting three prominent flares during the year 2010. Here, we present results using the combination of broadband (X-ray thr…
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…
The connection between the gamma-ray emission and millimeter flares in Fermi/LAT blazars
J. Leon-Tavares, E. Valtaoja, M. Tornikoski +2
We compare the gamma-ray photon flux variability of northern blazars in the Fermi/LAT First Source Catalog with 37 GHz radio flux density curves from the Metsahovi quasar monitorin…
