Accretion and jets in a low luminosity AGN: the nucleus of NGC 1052
  We aim to determine the properties of the central region of NGC 1052 using
X-ray and radio data. NGC 1052 (z=0.005) has been investigated for decades in
different energy bands and shows radio lobes and a low luminosity active
galactic nucleus (LLAGN). We use X-ray images from Chandra and radio images
from Very Large Array (VLA) to explore the morphology of the central area. We
also study the spectra of the nucleus and the surrounding region using
observations from Chandra and XMM-Newton. We find diffuse soft X-ray radiation
and hotspots along the radio lobes. The spectrum of the circum-nuclear region
is well described by a thermal plasma (T~0.6 keV) and a power law with photon
index Gamma~2.3. The nucleus shows a hard power law (Gamma~1.4) modified by
complex absorption. A narrow iron K-alpha line is also clearly detected in all
observations, but there is no evidence for relativistic reflection. The
extended emission is consistent with originating from extended jets and from
jet-triggered shocks in the surrounding medium. The hard power-law emission
from the nucleus and the lack of relativistic reflection supports the scenario
of inefficient accretion in an Advection Dominated Accretion Flow (ADAF).
