A Chandra study of Abell 795 -- a sloshing cluster with a FR0 radio
  galaxy at its center
  We present the first X-ray dedicated study of the galaxy cluster A795 and of
the Fanaroff-Riley Type 0 hosted in its brightest cluster galaxy. Using an
archival 30 ks \textit{Chandra} observation we study the dynamical state and
cooling properties of the intracluster medium, and we investigate whether the
growth of the radio galaxy is prevented by the surrounding environment. We
discover that A795 is a weakly cool core cluster, with an observed mass
deposition rate $\lessapprox 14\,$ M$_{\odot}$yr$^{-1}$ in the cooling region
(central $\sim$66 kpc). In the inner $\sim$ 30 kpc we identify two putative
X-ray cavities, and we unveil the presence of two prominent cold fronts at
$\sim$60 kpc and $\sim$178 kpc from the center, located along a cold ICM spiral
feature. The central galaxy, which is offset by 17.7 kpc from the X-ray peak,
is surrounded by a multi-temperature gas with an average density of
$n_{\text{e}} = 2.14 \times 10^{-2}$ cm$^{-3}$. We find extended radio emission
at 74-227 MHz centered on the cluster, exceeding the expected flux from the
radio galaxy extrapolated at low frequency. We propose that sloshing is
responsible for the spiral morphology of the gas and the formation of the cold
fronts, and that the environment alone cannot explain the compactness of the
radio galaxy. We argue that the power of the two cavities and the sloshing
kinetic energy can reduce and offset cooling. Considering the spectral and
morphological properties of the extended radio emission, we classify it as a
candidate radio mini-halo.
