Despite the archetypal status of the BTZ background in quantifying quantum aspects of black holes, several aspects at low temperatures remain incomplete. In this talk, I will discuss the behaviour of the Euclidean path integral at low temperatures in the context of AdS_3 supergravity, encompassing an analysis of quantum fluctuations in the near-horizon and far region. I'll clarify and rectify aspects of the bosonic fluctuations, highlighting the role of boundary conditions in AdS_3. I'll also account in detail for the contributions of Chern-Simons fields and spin-3/2 modes at low temperature. And finally, I’ll discuss how these results also impact our understanding of Kerr/CFT. Based on arXiv:2604.24834.
