description The Relativistic Heavy Ion Collider (RHIC) PHENIX experiment has provided new insights into the behavior of quark-gluon plasma (QGP) under extreme conditions. While PHENIX concluded data collection in 2016, the collaboration remains actively engaged in analyzing the rich dataset yielding the following three important results recently. (1) Heavy flavor (HF) with charm and bottom quark separation indicates a clear mass dependence observed in central collisions. Additionally, forward rapidity J/ψ and v2 measurements show a result consistent with zero, in contrast to LHC findings. (2) Precise direct photon yields obtained via large statistical datasets, spanning a wide range of transverse momentum (pT) and centrality bins have the scaling behavior across various large systems, and non-prompt direct photon results reveal temperature (Teff) dependence on pT. (3) Charged hadron production was examined in collision systems of varying sizes, revealing that RAA is primarily dependent on the overlap volume (Npart). Moreover, RdAu obtained by experimental Ncoll suggests the clear yield suppression in central collisions.
