Source position and its uncertainty:
From Mariotti et al.
- RA (J2000): 03 16 43.0
- Dec (J2000): +41 19 29
- no information available on positional uncertainty
Fermi: Neronov et al.
- this source is detected by Fermi with 6 sigma significance
in the energy range 30 GeV < E< 300 GeV.
- "The emission position is consistent with the head-tail radio galaxy
IC310 (z=0.0189, RA: 03 16 43.0 Dec: +41 19 29, J2000) located
in the outer region of the Perseus cluster of galaxies (Abell 426)."
Initially, this source was classified as an AGN of unknown type in
TeVCat. It was updated (121113) to a HBL based on its
classification in the Fermi 2nd AGN Catalog
(Ackermann et al. 2012).
Subsequently (181016), it has been re-classified as an AGN of unknown type
due to the discussion in Rieger & Levinson
From Rieger & Levinson
- The authors provide an overview of the source properties in the
context of a discussion of its classification:
- "The source ... has shown extreme VHE variability during a strong
flare in November 2012, revealing VHE flux variations on timescales as
short as delta-t of 5 minutes"
- "The 2012 VHE flare spectrum appears compatible with a single, hard
power law of photon index of approx. -2 (and possibly as low as
approx. -1.5) over a range from 70 GeV to 8.3 TeV, with no indications
of any internal absorption."
- "The source can reach high VHE flux levels, corresponding to an
isotropic-equivalent luminosity of 2 ×10e44 erg s−1."
- "IC 310 is commonly believed [e.g., Aleksic et al.
, 2014] to harbour
a black hole of mass 3 ×10e8 M_solar [but see also Berton et al.
for a ten times smaller estimate] and has for some time been
classified as a head-tail RG."
- "The apparent lack of jet bending along with more recent indications
for a one-sided pc-scale radio jet inclined at an angle of < approx. 38 deg
suggests, however, that IC 310 is a transitional source at the borderline
dividing low-luminosity RGs and BL Lac objects Kadler et al.
- "The extreme VHE variability along with the high VHE power and the
hard gamma-ray spectrum are surprising findings for a misaligned
- "IC 310 has subsequently (post - Nov 2017) shown a rather low TeV
emission state with a steeper spectrum (index approx. -2.4) measured
up to approx. 3 TeV and with little evidence for variability. The
multi-wavelength SED during this state appears to be satisfactorily
reproducible with a one-zone SSC model using parameters that are
comparable to those found for other misaligned, gamma-ray emitting AGN
MAGIC Collaboration et al.
- "The rapid variability measured in gamma rays and X-rays confirms
the blazar-like behavior of the source. The spectral behavior measured
in both energy bands suggest IC 310 could be linked to extreme HBL
objects. The apparent luminosity of IC 310 is a few orders of
magnitude lower than other extreme HBLs however and, atypical for an
HBL, it harbors a kiloparsec-scale radio structure. Thus, IC 310 could
be a peculiar type of a HBL."
- the redshift of z=0.0189 +/- 0.000033 comes from Bernardi et al.
