  We study Active Galactic Nucleus (AGN) activity in the fossil galaxy cluster,
RX J1416.4+2315. Radio observations were carried out using Giant Metrewave
Radio Telescope (GMRT) at two frequencies, 1420 MHz and 610 MHz. A weak radio
lobe that extends from the central nucleus is detected in 610 MHz map. Assuming
the radio lobe originated from the central AGN, we show the energy injection
into the Inter Galactic Medium (IGM) is only sufficient to heat up the central
50 kpc within the cluster core, while the cooling radius is larger ( $\sim$ 130
kpc). In the hardness ratio map, three low energy cavities have been
identified. No radio emission is detected for these regions. We evaluated the
power required to inflate the cavities and showed that the total energy budget
is sufficient to offset the radiative cooling. We showed that the initial
conditions would change the results remarkably. Furthermore, efficiency of
Bondi accretion to power the AGN has been estimated.
