Optical Variability of the very Radio-Loud Narrow line Seyfert 1 galaxy, 1H 0323+342
Clay S. Turner, Hugh R. Miller, Jeremy D. Maune +1
1H 0323+342 is optically one of the nearest and brightest very radio loud narrow line Seyfert 1 galaxies (vRL NLSy1). It is also one of the first vRLNLSy1s detected at gamma-ray en…
Optical polarisation variability of narrow line Seyfert 1 galaxies
E. Angelakis, S. Kiehlmann, I. Myserlis +6
We have monitored the R-band optical linear polarisation of ten jetted NLSy1 galaxies with the aim to quantify their variability and search for candidate long rotation of the polar…
Optical polarisation variability of radio loud narrow line Seyfert 1 galaxies. Search for long rotations of the polarisation plane
E. Angelakis, S. Kiehlmann, I. Myserlis +5
Narrow line Seyfert 1 galaxies (NLSy1s) constitute the AGN subclass associated with systematically smaller black hole masses. A few radio loud ones have been detected in MeV -- GeV…
Identification of Two Radio Loud Narrow Line Seyfert 1 Galaxies at Gamma-Ray Energies
Joseph R. Eggen, Jeremy D. Maune, H. R. Miller
We report the discovery of gamma-ray emission from two radio-loud narrow-line Seyfert 1 galaxies using data from Fermi/LAT: J0804+3853 (z = 0.211) and J1443+4725 (z = 0.502). The o…
A Tight Connection between Gamma-Ray Outbursts and Parsec-Scale Jet Activity in the Quasar 3C 454.3
Svetlana G. Jorstad, Alan P. Marscher, Paul S. Smith +42
We analyze the multifrequency behavior of the quasar 3C 454.3 during three prominent γ-ray outbursts: 2009 Autumn, 2010 Spring, and 2010 Autumn. The data reveal a repeating pattern…
The Variable Optical Polarization and FERMI Observations of PMN J0948+0022
Joseph R. Eggen, H. Richard Miller, Jeremy D. Maune
We report on observations of the γ-ray and optical photopolarimetric behavior of the radio-loud, narrow line type-1 Seyfert galaxy PMN J0948+0022 over a twenty seven month period.…
