| 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 issuggestive evidence of cavities along the minor axis and super-virialtemperature within 100 kpc, an indirect imprint of galactic outflow on the hotCGM. We would like to confirm our tentative yet exciting findings with deepdata. We ask for 430 ks XMM-Newton/EPIC time to precisely characterize theradial 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. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
