VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
V. A. Acciari, S. Ansoldi, L. A. Antonelli +230
Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…
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…
The broad-band properties of the intermediate synchrotron peaked BL Lac S2 0109+22 from radio to VHE gamma rays
MAGIC Collaboration, S. Ansoldi, L. A. Antonelli +163
The MAGIC telescopes observed S2 0109+22 in 2015 July during its flaring activity in high energy gamma rays observed by Fermi-LAT. We analyse the MAGIC data to characterise the ver…
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…
