Long Term Monitoring of the Dynamics and Particle Acceleration of Knots in the Jet of Centaurus A
J. L. Goodger, M. J. Hardcastle, J. H. Croston +16
We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the VLA and with Chandra, with which we measure the X-ray and radi…
Focusing Cosmic Telescopes: Exploring Redshift z~5-6 Galaxies with the Bullet Cluster 1E0657-56
M. Bradač, T. Treu, D. Applegate +7
The gravitational potential of clusters of galaxies acts as a cosmic telescope allowing us to find and study galaxies at fainter limits than otherwise possible and thus probe close…
Groups of Galaxies at Intermediate Redshift
Eric D. Miller, Marshall Bautz, Catherine Grant +6
Galaxy groups are key tracers of galaxy evolution, cluster evolution, and structure formation, yet they are difficult to study at even moderate redshift. We have undertaken a proje…
Radio Mode Outbursts in Giant Elliptical Galaxies
Paul Nulsen, Christine Jones, William Forman +4
Outbursts from active galactic nuclei (AGN) affect the hot atmospheres of isolated giant elliptical galaxies (gE's), as well as those in groups and clusters of galaxies. Chandra ob…
Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field
R. Voss, M. Gilfanov, G. R. Sivakoff +16
We study the X-ray luminosity function (XLF) of low mass X-ray binaries (LMXB) in the nearby early-type galaxy Centaurus A, concentrating primarily on two aspects of binary populat…
Discrete sources as the origin of the Galactic X-ray ridge emission
Revnivtsev M., Sazonov S., Churazov E. +3
An unresolved X-ray glow (at energies above a few kiloelectronvolts) was discovered about 25 years ago and found to be coincident with the Galactic disk -the Galactic ridge X-ray e…
