Multiphase ISM in low luminosity radio galaxies: A case study of NGC 708
  We present a multi-wavelength study of a nearby radio loud elliptical galaxy
NGC708, selected from the Bologna B2 sample of radio galaxies. We obtained
optical broad band and narrow images from IGO 2m telescope (Pune, India). We
supplement the multi-wavelength coverage of the observation by using X-ray data
from Chandra, infrared data from 2MASS, Spitzer and WISE and optical image from
DSS and HST. In order to investigate properties of interstellar medium, we have
generated unsharp-masked, color, residual, quotient, dust extinction, H_alph
emission maps. From the derived maps it is evident that cool gas, dust, warm
ionized H_alpha and hot X-ray gas are spatially associated with each other. We
investigate the inner and outer photometric and kinematic properties of the
galaxy using surface brightness profiles. From X-ray 2d beta model, unsharp
masking, surface brightness profiles techniques, it is evident that pair of
X-ray cavities are present in this system and which are ~5.6 Kpc away from the
central X-ray source.
