Evidence of Heavy Obscuration in the Low-Luminosity AGN NGC 4941
  We present the results obtained from timing and spectral studies of the
highly obscured low luminosity active galactic nucleus NGC~4941 using data
obtained from the {\it Nuclear Spectroscopic Telescope Array} and the {\it Neil
Gehrels Swift} Observatories. We find similar variability in $3-10$~keV and
$10-60$~keV energy ranges with fractional rms variability of $\sim$14\%. We
investigate broad-band spectral properties of the source in 3-150 keV range,
using data from {\it NuSTAR} and {\it Swift}/BAT, with phenomenological slab
model and physically motivated {\tt mytorus} model. From the spectral analysis,
we find heavy obscuration with the global average column density of the
obscured material as $3.09^{+1.68}_{-1.01} \times 10^{24}$ cm$^{-2}$. Evidence
of a strong reflection component is observed in the spectrum. We detect a
strong iron line with an equivalent width of $\sim$1~keV. From the slab model,
we obtain the exponential cutoff energy as $177^{+92}_{-16}$~keV. From this, we
estimate the Compton cloud properties with the hot electron temperature
$kT_{\rm e} = 59^{+31}_{-5}$~keV and the optical depth $\tau =
2.7^{+0.2}_{-1.6}$.
