Models of Optical Emission Lines To Investigate Narrow-Line Seyfert 1 Galaxies in Spectroscopic Databases

G. La Mura, D. Bastieri, M. Berton +6

Thanks to the execution of extensive spectroscopic surveys that have covered large fractions of the sky down to magnitudes as faint as , it has been possible to ident…

Hunting misaligned radio-loud AGN (MAGN) candidates among the uncertain -ray sources of the third Fermi-LAT Catalogue

G. Chiaro, M. Meyer, N. Alvarez Crespo +6

BL Lac Objects (BL Lacs) and Flat Spectrum Radio Quasars (FSRQs) are radio-loud active galaxies (AGNs) whose jets are seen at a small viewing angle (blazars), while Misaligned Acti…

Multi-messenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922A

The IceCube, Fermi-LAT, MAGIC +13

Individual astrophysical sources previously detected in neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neut…

Long-term monitoring of the broad-line region properties in a selected sample of AGN

Dragana Ilic, Alla I. Shapovalova, Luka C. Popovic +8

We present the results of the long-term optical monitoring campaign of active galactic nuclei (AGN) coordinated by the Special Astrophysical Observatory of the Russian Academy of S…

Einstein@Home discovers a radio-quiet gamma-ray millisecond pulsar

C. J. Clark, H. J. Pletsch, J. Wu +18

Millisecond pulsars (MSPs) are old neutron stars that spin hundreds of times per second and appear to pulsate as their emission beams cross our line of sight. To date, radio pulsat…

Probing narrow-line Seyfert 1 galaxies in the southern hemisphere

S. Chen, M. Berton, G. La Mura +7

We present a new accurate catalog of narrow-line Seyfert 1 galaxies (NLS1s) in the southern hemisphere from the Six-degree Field Galaxy Survey (6dFGS) final data release, which is…
