  "abstract": "We present new Keck Cosmic Web Imager (KCWI) observations of the central few kiloparsecs of NGC 1275, 2023ascl.soft01019Nvthe brightest cluster galaxy of the Perseus Cluster. These integral field spectroscopic data reveal a warm-ionized outflow traced by H β and the [O III ] doublet extending out to ∼2.5 kpc from the nucleus. The warm-ionized outflow has an [O III ]-derived v ₅₀ of up to ∼570 km s ⁻¹ , w ₈₀ of up to 3780 km s ⁻¹ , and H β -derived outflowing mass of (2.7 ± 0.3) × 10 ⁶ M ⊙ . Our H β -derived warm-ionized outflowing mass rate of 2.7 ± 0.7 M ⊙ yr ⁻¹ is comparable to the estimated cold molecular disk accretion rate of 1−10 M ⊙ yr ⁻¹ , which could be a sign of self-regulation between the parsec-scale cold gas feeding the active galactic nucleus (AGN) and the warm wind accelerated out to kiloparsec scales. In the host galaxy, we detect an enhancement in the [O III ]/H β ratio in the direction of the receding jet, which may imply jet interaction with the host interstellar medium. The outflow component also shows a clear enhancement of [O III ]/H β that positively correlates with w ₈₀ and v ₅₀ , indicative of AGN influence and/or fast shocks. Both the outflow and host galaxy [O III ]/H β ratio decrease with increasing distance from the center, showing that the influence of the AGN is confined to the central ∼2 kpc. These results are the first resolved measurements of a kiloparsec-scale ionized wind in NGC 1275 and provide a view into how both jets and winds contribute to the feedback cycles in complex cool core cluster systems.",
