Extreme blazars

  title={Extreme blazars},
  author={Gabriele Ghisellini},
TeV emission can be a common characteristic of low power blazars. This is in line with the sequence of blazars relating the observed bolometric luminosity with their overall spectral energy distribution. Detecting new TeV blazars, possibly at different redshifts, is important for studying the particle acceleration process operating in the jet, and it is even more important for studying the far infrared–optical background. Recent studies of low power BL Lacs suggest that the particle…

The power of blazar jets
We estimate the power of relativistic, extragalactic jets by modelling the spectral energy distribution of a large number of blazars. We adopt a simple one-zone, homogeneous, leptonic synchrotron and
The disc—jet relation in strong-lined blazars
The relation between emission from the accretion disc (thermal) and the jet (non-thermal) in blazars is still a mystery as, typically, the beamed jet emission swamps the disc emission even in the
Temporal analysis of the least energetic events in pulsar data from observations with the high energy stereoscopic system
It has been more than 60 years since astronomers turned their attention towards the 7֊ray window (> 100 TeV). Nowadays, 7֊ray astronomy has won its place as a separate branch of astronomy in its own
Kinematical diagrams for conical relativistic jets
We present diagrams depicting the expected inter-dependences of two key kinematical parameters of radio knots in the parsec-scale jets of blazars, deduced from VLBI observations. The two parameters
Scientific Highlights from Observations of Active Galactic Nuclei with the MAGIC Telescope
Since 2004, the MAGIC γ‐ray telescope has newly discovered 6 TeV blazars. The total set of 13 MAGIC‐detected active galactic nuclei includes well‐studied objects at other wavelengths like Markarian
Multiband Diagnostics of Unidentified 1FGL Sources with Suzaku and Swift X-ray Observations
We have analyzed all the archival X-ray data of 134 unidentified (unID) gamma-ray sources listed in the first Fermi/LAT (1FGL) catalog and subsequently followed up by the Swift/XRT. We constructed
First detection of VHE gamma-ray emission from TXS~1515--273, study of its X-ray variability and spectral energy distribution
We report here on the first multi-wavelength (MWL) campaign on the blazar TXS 1515-273, undertaken in 2019 and extending from radio to very-high-energy gamma rays (VHE). Up until now, this blazar had

Progress in unveiling extreme particle acceleration in persistent astrophysical jets
The most powerful persistent accelerators in the Universe are jetted active galaxies. Blazars, galaxies whose jets are directed towards Earth, dominate the extragalactic γ-ray sky. Still, most of the


Multiwavelength Observations of Markarian 421 During a TeV/X-Ray Flare: Erratum
A TeV flare from the BL Lac object Mrk 421 was detected in May of 1994 by the Whipple Observatory air Cherenkov experiment during which the flux above 250 GeV increased by nearly an order of
A theoretical unifying scheme for gamma-ray bright blazars
ABSTRA C T The phenomenology of g-ray bright blazars can be accounted for by a sequence in the source power and intensity of the diffuse radiation field surrounding the relativistic jet.
Bulk Acceleration in Relativistic Jets and the Spectral Properties of Blazars
Models for the synchrotron and inverse Compton emission from relativistic jets with bulk acceleration are studied, under the assumption that the bulk velocity increases with increasing distance along
Internal shocks in blazar jets
The discovery of strong γ–ray and hard X–ray emission and the results from various multifrequency campaigns have disclosed new aspects of the blazar phenomenology, leading to a much more robust
BeppoSAX Observations of Unprecedented Synchrotron Activity in the BL Lacertae Object Markarian 501
The BL Lacertae object Markarian 501, one of only three extragalactic sources (with Mrk 421 and 1ES 2344+514) so far detected at TeV energies, was observed with the BeppoSAX satellite in 1997 April
Intraday Variability in Quasars and BL LAC Objects
Active galactic nuclei with flat radio spectra exhibit significant variations of continuum flux density on time scales of days or less throughout the entire wavelength range. These rapid variations
Hard X-ray properties of blazars
We have considered all blazars observed in the X{ray band and for which the slope of the X{ray spectrum is available. We have collected 421 spectra of 268 blazars, including 12 archival unpublished
A jet model for the gamma-ray emitting blazar 3C 279
The physical conditions in the gamma-ray-emitting blazar 3C 279 are discussed. The requirement of transparency for gamma-rays, together with the observation of rapid variability, imply that the

ABSTRA C T We collect data at well-sampled frequencies from the radio to the g-ray range for the following three complete samples of blazars: the Slew survey, the 1-Jy samples of BL Lacs and the 2-Jy
X-Ray Emission of Markarian 421: New Clues from Its Spectral Evolution. I. Temporal Analysis
Mrk 421 was repeatedly observed with BeppoSAX in 1997 and 1998. This is the first of two papers where we present the results of a thorough temporal and spectral analysis of all the data available to
