Unveiling the Dual Nature of V1180 Cas: UXor-like Dips and EXor-like Bursts Across a Decade

Tarak Chand, Saurabh Sharma, Koshvendra Singh +15

We present a detailed analysis of the long-term photometric and spectroscopic evolution of V1180 Cas over a decade, aiming to identify the dominant mechanisms behind its variabilit…

Dissecting the long-term emission behaviour of the BL Lac object Mrk 421

M. I. Carnerero, C. M. Raiteri, M. Villata +4

We report on long-term multi-wavelength monitoring of blazar Mrk 421 by the GASP-WEBT collaboration and Steward Observatory, and by the Swift and Fermi satellites. We study the sou…

Multiwavelength behaviour of the blazar OJ 248 from radio to γ-rays

M. I. Carnerero, C. M. Raiteri, M. Villata +4

We present an analysis of the multiwavelength behaviour of the blazar OJ 248 at z = 0.939 in the period 2006-2013. We use low-energy data (optical, near-infrared, and radio) obtain…

MAGIC gamma-ray and multifrequency observations of flat spectrum radio quasar PKS 1510-089 in early 2012

MAGIC Collaboration, J. Aleksić, S. Ansoldi +218

Among more than fifty blazars detected in very high energy (VHE, E>100GeV) gamma-rays, only three belong to the subclass of Flat Spectrum Radio Quasars (FSRQs). MAGIC observed FSRQ…

The awakening of BL Lacertae: observations by Fermi, Swift, and the GASP-WEBT

C. M. Raiteri, M. Villata, F. D'Ammando +4

Since the launch of the Fermi satellite, BL Lacertae has been moderately active at gamma-rays and optical frequencies until May 2011, when the source started a series of strong fla…

Variability of the blazar 4C 38.41 (B3 1633+382) from GHz frequencies to GeV energies

C. M. Raiteri, M. Villata, P. S. Smith +74

The quasar-type blazar 4C 38.41 (B3 1633+382) experienced a large outburst in 2011, which was detected throughout the entire electromagnetic spectrum. We present the results of low…
