We present the X-ray properties of the 'Teacup AGN' (SDSS J1430+1339), a z=0.085 type 2 quasar which is interacting dramatically with its host galaxy. Spectral modelling of the central quasar reveals a powerful, highly obscured AGN with a column density of N_ H=(4.2-6.5)× 10^23 cm^-2 and an intrinsic luminosity of L_ 2-10 keV=(0.8-1.4)× 10^44 erg s^-1. The current high bolometric luminosity inferred (L_ bol≈ 10^45-10^46 erg s^-1) has ramifications for previous interpretations of the Teacup as a

High resolution Chandra imaging data reveal a ≈ 10 kpc loop of X-ray emission, co-spatial with the 'eastern bubble' previously identified in luminous radio and ionised gas (e.g., [OIII] line) emission. The X-ray emission from this structure is in good agreement with a shocked thermal gas, with T=(4-8)× 10^6 K, and there is evidence for an additional hot component with T≳ 3× 10^7 K. Although the Teacup is a radiatively dominated AGN, the estimated ratio between the bubble power and the X-ray luminosity is in remarkable agreement with observations of ellipticals, groups, and clusters of galaxies undergoing AGN feedback.
