Query: The counterpart/s of IGR J20159+3713/SWIFT J2015.9+3715: dissecting a
  complex region with emission from keV to TeV   We report on the identification of a new soft gamma-ray source, namely IGR
J20159+3713/SWIFT J2015.9+3715, first detected by INTEGRAL/IBIS and then
confirmed by Swift/BAT. The source, which has an observed 20-100 keV flux in
the range (0.7-1.4) x 10^(-11) erg cm^(-2) s^(-1), encloses a Fermi variable
source (2FGL J2015.6+3709) and is spatially close to a TeV emitter (VER
J2016+372). Thanks to X-ray follow-up observations performed with the X-ray
telescope on board Swift, we have been able to identify the new IBIS/BAT
detection with the combined emission of the blazar B2013+370 and the
cataclysmic variable RX J2015.6+3711. Both objects show variability in X-rays,
with the CV being the most variable of the two. At high energies (above 20 keV)
the emission is likely dominated by B2013+370, but the contribution from RX
J2015.6+3711 is not negligible. The blazar emits up to GeV frequencies where it
is seen by Fermi, while the cataclysmic variable has a bremsstrahlung
temperature which is too low to provide any contribution at these high
energies. These findings also indicate that the INTEGRAL/Swift source is not
associated with the TeV emission, which is most likely due to the supernova
remnant (SNR)/pulsar wind nebula (PWN) CTB 87.
