The faint voice of a radio-weak BL Lacertae: modeling the broadband emission of WISE~J141046.00+740511.2
A. M. Carulli, F. L. Vieyro, M. M. Reynoso +2
The WISE source, J141046.00+740511.2, has been recently observed from radio to rays. Although the optical spectrum is consistent with a BL Lacertae (BL Lac) object, the source…
Optical monitoring in southern blazars. Analysis of variability and spectral colour behaviours
L. Zibecchi, I. Andruchow, E. Ej. Marchesini +2
We present the results of the optical monitoring of 18 southern blazars in the V and R Johnson-Cousins bands. Our main objective is to study the variations in the optical flux and…
Disentangling the nature of the prototype radio weak BL Lac: Contemporaneous multifrequency observations of WISE J141046.00 + 740511.2
E. J. Marchesini, V. Reynaldi, F. Vieyro +13
Context. The gamma-ray emitting source WISE J141046.00+740511.2 has been associated with a Fermi-LAT detection by crossmatching with Swift/XRT data. It has shown all the canonical…
Multi-wavelength Analysis and Modeling of OJ 287 During 2017-2020
Raj Prince, Aditi Agarwal, Nayantara Gupta +4
Context. The blazar OJ 287 has been proposed as a binary black hole system based on its periodic optical outburst. Among blazars with parsec scale jets, the black hole binary syste…
Optical spectroscopic classification of 35 hard X-ray sources from the Swift-BAT 70-month catalogue
E. J. Marchesini, N. Masetti, E. Palazzi +15
The nature of a substantial percentage (about one fifth) of hard X-ray sources discovered with the BAT instrument onboard the Neil Gehrels Swift Observatory (hereafter Swift) is un…
The -ray sky seen at X-ray energies I. Searching for the connection between X-rays and -rays in Fermi BL Lac objects
E. J. Marchesini, A. Paggi, F. Massaro +4
BL Lac objects are an extreme type of active galactic nuclei (AGNs) that belong to the largest population of -ray sources: blazars. This class of AGNs shows a double-bumped spec…
