The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

© 2018. The American Astronomical Society. All rights reserved. We present the X-ray properties of the "Teacup AGN" (SDSS J1430+1339), a z = 0.085 type 2 quasar that is interacting dramatically with its host galaxy. Spectral modeling of the central quasar reveals a powerful, highly obscured active galactic nucleus (AGN) with a column density of N H = (4.2-6.5) ×1023 cm-2 and an intrinsic luminosity of L 2-10 keV = (0.8-1.4) ×1044 erg s-1. The current high bolometric luminosity inferred (L bol ≈1045-1046 erg s-1) has ramifications for previous interpretations of the Teacup as a fading/dying quasar. High-resolution Chandra imaging data reveal a ≈10 kpc loop of X-ray emission, cospatial with the "eastern bubble" previously identified in luminous radio and ionized gas (e.g., [O iii] line) emission. The X-ray emission from this structure is in good agreement with a shocked thermal gas, with T = (4-8) ×106 K, and there is evidence for an additional hot component with T3 ×107 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.
