ABSTRACT | |
The circumgalactic medium (CGM) plays an instrumental role in galaxy evolution. From shallow archival data of Suzaku and XMM, we have detected the extended (~150 kpc) and massive hot CGM of NGC 3221, an L* star-forming galaxy. There is suggestive evidence of cavities along the minor axis and super-virial temperature within 100 kpc, an indirect imprint of galactic outflow on the hot CGM. We would like to confirm our tentative yet exciting findings with deep data. We ask for 430 ks XMM-Newton/EPIC time to precisely characterize the radial and angular profiles of surface brightness, density, temperature, pressure, and entropy of the hot CGM of NGC 3221 through imaging, spectroscopy, and modeling. Our results would set the precedence for studying the hot CGM in the current and next decade. |
