Optical Imaging & Spectral Study of FR-I Type Radio Galaxy:CTD 086 (B2
  1422+26B)
  We present optical imaging and spectroscopic studies of the Fanaroff \& Riley
class I (FR I) radio galaxy CTD 086 based on Hubble Space Telescope (HST) and
Sloan Digital Sky Survey (SDSS) observations. We use isophote shape analysis to
show that there is no stellar disk component within CTD 086 and further that
the morphological class of the galaxy is most likely E2. Optical spectroscopy
of this galaxy reveals the presence of narrow emission lines only, and thus it
qualifies to be termed as a narrow-line radio galaxy (type 2 AGN). We also
extract stellar kinematics from the absorption-line spectra of CTD 086 using
Penalized Pixel-Fitting method and derive the black hole mass MBH to be equal
to (8.8\pm2.4)\times10^{7} Msun.
