A summary of the searches for heavy quarks and heavy bosons decaying to top-antitop pairs ( resonances) with 14.3 fb−1 of the proton-proton collisions data at √s = 8 TeV delivered by the LHC and recorded by the ATLAS detector is presented here. The searches for heavy quarks are performed in context of the chiral fourth generation and vector-like quarks. One of the searches is also sensitive to the production of four top quarks and positively-charged top quark pairs. The search for resonances is motivated by the narrow width topcolor leptophobic Z’ and broad width Kaluza-Klein gluon models.
