Long Term Multi-band Near Infra-Red Variability of the Blazar OJ 287 during 2007--2021
Alok C. Gupta, Pankaj Kushwaha, L. Carrasco +9
We present the most extensive and well-sampled long-term multi-band near-infrared (NIR) temporal and spectral variability study of OJ 287, considered to be the best candidate binar…
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…
Multiwavelength Photometric and Spectropolarimetric Analysis of the FSRQ 3C 279
V. M. Patiño-Álvarez, S. Fernandes, V. Chavushyan +6
In this paper, we present light curves for 3C 279 over a time period of six years; from 2008 to 2014. Our multiwavelength data comprise 1 mm to gamma-rays, with additional optical…
The mid-2016 flaring activity of the flat spectrum radio quasar PKS 2023-07
G. Piano, P. Munar-Adrover, L. Pacciani +8
Flat spectrum radio quasars (FSRQs) can suffer strong absorption above E = 25/(1+z) GeV, due to gamma-gamma interaction if the emitting region is at sub-parsec scale from the super…
Multiband variability studies and novel broadband SED modeling of Mrk 501 in 2009
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +290
We present an extensive study of the BL Lac object Mrk 501 based on a data set collected during the multi-instrument campaign spanning from 2009 March 15 to 2009 August 1 which inc…
Multi-band study of RX J0838-2827 and XMM J083850.4-282759: a new asynchronous magnetic cataclysmic variable and a candidate transitional millisecond pulsar
N. Rea, F. Coti Zelati, P. Esposito +23
In search for the counterpart to the Fermi-LAT source 3FGL J0838.8-2829, we performed a multi-wavelength campaign, in the X-ray band with Swift and XMM-Newton, performed infrared,…
