Testing the magnetic flux paradigm for AGN radio loudness with a radio intermediate quasar
Wara Chamani, Tuomas Savolainen, Kazuhiro Hada +1
For understanding the diversity of jetted active galactic nuclei (AGN) and especially the puzzling wide range in their radio-loudness, it is important to understand what role the m…
Joint XMM-Newton and NuSTAR observations of the reflection spectrum of III Zw 2
Wara Chamani, Karri Koljonen, Tuomas Savolainen
Detecting and modelling the reprocessed hard X-ray emission component in the accretion flow, so-called reflection spectrum is a main tool to estimate black hole spins in a wide ran…
Long term variability and correlation study of the blazar 3C 454.3 in radio, NIR and optical wavebands
A. Sarkar, V. R. Chitnis, A. C. Gupta +11
We performed a long-term optical (B, V, R bands), infra-red (J and K bands) and radio band (15, 22, 37 GHz band) study on the flat spectrum radio quasar, 3C 454.3, using the data c…
X-ray, UV, and Radio Timing Observations of the Radio Galaxy 3C 120
Alan P. Marscher, Svetlana G. Jorstad, Karen E. Williamson +7
We report the results of monitoring of the radio galaxy 3C 120 with the Neil Gehrels Swift Observatory, Very Long Baseline Array, and Metsähovi Radio Observatory. The UV-optical co…
Radio jets and gamma-ray emission in radio-silent narrow-line Seyfert 1 galaxies
A. Lähteenmäki, E. Järvelä, V. Ramakrishnan +4
We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37 GHz that were previously classified as radio silent and two that were classified as radio quiet. These detections r…
Multiwavelength observations of the blazar BL Lacertae: a new fast TeV gamma-ray flare
A. U. Abeysekara, W. Benbow, R. Bird +74
Combined with very-long-baseline interferometry measurements, the observations of fast TeV gamma-ray flares probe the structure and emission mechanism of blazar jets. However, only…
