Multiple Point-Symmetric Ejections in IC 4634
Martin A. Guerrero, Luis F. Miranda, You-Hua Chu
We present a spatio-kinematical study of the planetary nebula (PN) IC 4634 which has experienced several episodes of point-symmetric ejections oriented at different directions. The…
The X-ray Scaling Properties of Virialized Systems
Alastair J. R. Sanderson, Trevor J. Ponman
Virialized systems, such as clusters and groups of galaxies, represent an ideal laboratory for investigating the formation and evolution of structure on the largest scales. Further…
Non-thermal bremsstrahlung as the dominant hard X-ray continuum emission from the supernova remnant MSH14-63 (RCW 86)
Jacco Vink, Johan Bleeker, Jelle Kaastra +3
We present an analysis of the X-ray emission of the supernova remnant MSH14-63, which was partially covered by four observations with XMM-Newton. The detection of Fe K emission at…
XMM-Newton observations of MSH 14-63 (RCW 86)
Jacco Vink, Johan Bleeker, Jelle Kaastra +2
We present an analysis of the X-ray emission of the supernova remnant MSH14-63, which was partially covered by three observations with XMM-Newton. The detection of Fe K emission at…
The ISM Interactions of a Runaway LBV Nebula in the LMC
Charles W. Danforth, You-Hua Chu
New observations of the Magellanic Cloud Luminous Blue Variable candidate S119 (HD269687) show the relationship of the star to its environs. Echelle spectroscopy and high-resolutio…
CIV absorption from hot gas inside supergiant shell LMC4 observed with HST and IUE
D. J. Bomans, K. S. de Boer, J. Koornneef +1
High resolution ultraviolet spectra with HST-GHRS of two stars in the direction of the supergiant shell LMC4 unambiguously show absorption by substantial quantities of CIV gas at v…
