==Radio jets==
NGC 1272 has two radio jets which are powered by an [[Active galactic nucleus|AGN]] at the center of the galaxy. The jets are bent and have a radius of curvature of ~{{convert|2|kpc|ly|abbr=on|lk=on|order=flip}}. The morphology of the jets indicate that the jets are affected by [[ram-pressure stripping]] caused by the motion of NGC 1272 though the [[Intracluster medium|ICM]] of the [[Perseus Cluster]]. Due to the proximity of NGC 1272 to the center of the Perseus Cluster, the galaxy experiences [[Ram pressure|ram-pressure]] on an order of magnitude larger than any other bent-double in the cluster and experiences stronger ram-pressure than other bent-doubles outside of the cluster.<ref name=":2" />
==ISM removal==
The small bending radius of the jets requires NGC 1272 to have essentially no [[Interstellar medium|ISM]] at radii of ~2 kpc and beyond. The ISM of NGC 1272 may have also been removed though [[ram-pressure stripping]]. However, [[Ram pressure|ram-pressure]] alone cannot remove a fraction of the [[Interstellar medium|ISM]] from deep within the galaxy. Another process, such as AGN feedback in NGC 1272 must have initially removed a large fraction of the ISM before [[Ram pressure|ram-pressure]] can become effective in removing the ISM.<ref name=":2" />
==Globular clusters==
It is estimated that around 12,000 [[globular clusters]] surround NGC 1272.<ref>{{Cite journal|last1=Harris|first1=William E.|last2=Mulholland|first2=Courtney J.|date=2017|title=Detection of the Stellar Intracluster Medium in Perseus (Abell 426)|url=http://stacks.iop.org/0004-637X/839/i=2/a=102|journal=The Astrophysical Journal|language=en|volume=839|issue=2|pages=102|doi=10.3847/1538-4357/aa6a59|issn=0004-637X|arxiv=1703.10204|bibcode=2017ApJ...839..102H|s2cid=119368268 |doi-access=free }}</ref>
