Planck Intermediate Results. I. Further validation of new Planck clusters with XMM-Newton
The Planck Collaboration, N. Aghanim, M. Arnaud +182
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-…
Jet trails and Mach cones: The interaction of microquasars with the ISM
Doosoo Yoon, Brian Morsony, Sebastian Heinz +4
A sub-set of microquasars exhibit high peculiar velocity with respect to the local standard of rest due to the kicks they receive when being born in supernovae. The interaction bet…
Coronal radiation of a cusp of spun-up stars and the X-ray luminosity of Sgr A*
S. Sazonov, R. Sunyaev, M. Revnivtsev
Chandra has detected optically thin, thermal X-ray emission with a size of ~1 arcsec and luminosity ~10^33 erg/s from the direction of the Galactic supermassive black hole (SMBH),…
Resonant scattering in galaxy clusters for anisotropic gas motions on various spatial scales
I. Zhuravleva, E. Churazov, S. Sazonov +2
The determination of characteristic amplitudes and anisotropy of hot gas motions in galaxy clusters from observations of the brightest resonance lines is discussed. Gas motions aff…
Fast optical variability of SS 433
R. A. Burenin, M. G. Revnivtsev, I. M. Khamitov +4
We study the optical variability of the peculiar Galactic source SS 433 using the observations made with the Russian Turkish 1.5-m telescope (RTT150). A simple technique which allo…
Planck early results: first assessment of the High Frequency Instrument in-flight performance
Planck HFI Core Team, P. A. R. Ade, N. Aghanim +163
The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six w…
