Evidence of bar--driven secular evolution in the gamma--ray narrow--line Seyfert 1 galaxy FBQS J164442.5+261913
A. Olguín-Iglesias, J. K. Kotilainen, J. León Tavares +2
We present near--infrared (NIR) imaging of FBQS J164442.5+261913, one of the few --ray emitting Narrow Line Seyfert 1 (NLSy1) galaxies detected at high significance level by…
On the Redshifts of the BL Lac 3FGL J0909.0+2310 and its Close Companion
D. Rosa-Gonzalez, S. Coutiño de Leon, Y. D. Mayya +10
We report on the redshift of the BL Lac object 3FGL J0909.0+2310 based on observations obtained with the OSIRIS Multi Object Spectrograph (MOS) mounted on the 10.4-m Gran Telescopi…
Obscured flat spectrum radio AGN as sources of high-energy neutrinos
G. Maggi, S. Buitink, P. Correa +7
Active Galactic Nuclei (AGN) are believed to be one of the main source candidates for the high-energy (TeV-PeV) cosmic neutrino flux recently discovered by the IceCube neutrino obs…
230 GHz VLBI observations of M87: event-horizon-scale structure at the enhanced very-high-energy -ray state in 2012
Kazunori Akiyama, Ru-Sen Lu, Vincent L. Fish +45
We report on 230 GHz (1.3 mm) VLBI observations of M87 with the Event Horizon Telescope using antennas on Mauna Kea in Hawaii, Mt. Graham in Arizona and Cedar Flat in California. F…
