Abstract: We present a multi-wavelength spectral and temporal analysis of the blazar OJ during its recent activity between July -- July This period is characterized by intense variability from optical to X-rays and frequent daily detections at {\it Fermi}-LAT. GeV Variability of Blazars with GLAST-LAT The GLAST LAT is an all-sky monitor which will yield continuous GeV monitoring for hundreds of blazars, with sampling down to ~1 day for the brightest sources.

Long-term monitoring yields the high quality light curves (evenly-sampled, uninterrupted, long-duration) which are key for break. We perform a multi-wavelength polarimetric study of the quasar CTA during an extraordinarily bright $\gamma$-ray outburst detected by the {\it Fermi} Large Area Telescope in September-October when the source reached a flux of F$_{>~\mathrm{MeV}} =\pm\times10^{-6}$ photons.

Dec 04,  · The spectral variability of the blazar CTA during a recent extreme outburst could be explained by a twisted, inhomogeneous jet containing regions of different orientations that vary in lowdowntracks4impact.com by: Many UGSs could be blazars, the largest identiﬁed population of extragalactic -ray sources, but how many are actually blazars is not yet known due in part to the incompleteness of the catalogs used for the associations (Ackermann et al).

The ﬁrst step to reduce the number of UGSs is therefore to recognize those that could be blazars. Index Introduction Leptonic Models Hadronic models Conclusions Caveat lector.

The X-ray UniverseProceedings of the conference held June, in Rome, Italy. Edited by J.-U. Ness and S. Migliari. Home. Blazars, the most extreme variety of active galactic nuclei (AGN) and the most luminous long-lived individual objects in the universe, continue to pose major astrophysical puzzles.

This international conference will be devoted to recent progress in observational and theoretical aspects of blazars and advances in our understanding of the. Abstract The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in October.

In addition to these gamma-ray observations, F-GAMMA, GASP-WEBT, PAIRITEL, MDM, ATOM, Swift, and Chandra provided radio to X-ray coverage.

Jan 26,  · The low‐frequency peaked BL Lac object 3C 66A was the subject of an extensive multi‐wavelength campaign from July till Aprilwhich included quasi‐simultaneous observations at optical, X‐rays and very high energy gamma‐rays.

Here we apply the hadronic Synchrotron‐Proton Blazar (SPB) model to the observed spectral energy distribution time‐averaged Cited by: 2. Then we explore the associated hadronic signatures ex- pected from TeV blazars in the case where jets of BL Lac objects and FR-I radio galaxies are accelerators of ultra-high- energy cosmic rays (UHECRs, with energies above the an- kle of w 10 eV), assuming the validity of the leptonic SSC parameters inferred from rapidly variable AGN.

Abstract book, id. It has been known for a long time that blazars are variable, both on short (minutes to days) and long (weeks to years) timescales.

Various models exist to explain the mechanisms causing variability, and disentangling them has also been particularly hard. This article shortly introduces Gaussian processes as a new approach for modelling time series in the field of blazar physics.
