Abstract
Two searches for neutral heavy Higgs: $H/A \rightarrow \tau\tau$ and $A \rightarrow Zh, h \rightarrow b\bar{b}$ are presented with 36.1 fb$^{-1}$ of data at $\sqrt{s} = 13$ TeV recorded by the ATLAS detector at the LHC. There is no statistically significant excess. Upper limits on cross-section times branching fraction and the interpretation of results in the $m_A$-$\tan\beta$ plane are shown within the MSSM. Large areas of high $\tan\beta$ are excluded by $H/A \rightarrow \tau\tau$: $\tan\beta>15$ for $m_A = 1$ TeV in the hMSSM scenario at the 95% confidence level.
