Cen A and its interaction with the x-ray emitting interstellar medium
D. M. Worrall, R. P. Kraft, M. Birkinshaw +4
As the closest radio galaxy, Centaurus A is a powerful laboratory for the X-ray study of radio-emitting structures and their interactions with the hot interstellar medium (ISM). Th…
Infall of the Elliptical Galaxy NGC 1404 into the Fornax Cluster
M. Machacek, A. Dosaj, W. Forman +5
We use three Chandra observations, totalling 134.3 ks, to constrain the dynamical motion of NGC1404 falling towards the dominant elliptical NGC1399 through the Fornax ICM. NGC1404'…
Hot Gas Structure in the Elliptical Galaxy NGC 4472
B. A. Biller, C. Jones, W. R. Forman +2
We present X-ray spectroscopic and morphological analyses using Chandra ACIS and ROSAT observations of the giant elliptical galaxy NGC 4472 in the Virgo cluster. We discuss previou…
Chandra and XMM-Newton Observations of the Nucleus of Centaurus A
D. A. Evans, R. P. Kraft, D. M. Worrall +4
We present X-ray spectra of the nucleus of the nearby radio galaxy Centaurus A from observations with the XMM-Newton EPIC CCD cameras (two exposures separated by 12 months) and the…
Reflections of AGN Outbursts in the Gaseous Atmosphere of M87
W. Forman, P. Nulsen, S. Heinz +7
We combined deep Chandra, ROSAT HRI, and XMM-Newton observations of M87 to study the impact of AGN outbursts on its gaseous atmosphere. Many X-ray features appear to be a direct re…
