The ATLAS experiment can measure consistent proton collisions at the highest energies with $\sqrt{s}=13.6$ TeV. This allows many previously impossible measurements of standard model physics and searches for new physics.

This talk presents the recent results of searches for high-mass Heavy Neutral Leptons (HNLs) using the run 2 dataset. HNLs and the Weinberg Operator are given new limits into the TeV scale in electron and muon mixing channels. Finally, I explore the possibility of future measurements with extended exotic models. These models can lead to slow signals in the detector, requiring dedicated hardware-level triggers.
