IXPE Unveils New Insights into Supernova Remnant RCW 86
NASA's Imaging X-ray Polarimetry Explorer (IXPE) mission has conducted a new observation of the supernova remnant RCW 86. This observation contributes to a comprehensive understanding of the supernova based on data from multiple telescopes.
Previous Discoveries: The Enigmatic Cavity
Astronomers previously utilized NASA's Chandra X-ray Observatory to study RCW 86. These observations revealed a large "cavity" region surrounding the system, which appeared to cause the supernova to expand more rapidly than anticipated. This low-density cavity may also have influenced RCW 86's distinct shape.
IXPE's Contribution: Halting at the Edge
IXPE's recent observation focused on the outer rim of this supernova.
It is hypothesized that the supernova's expansion halted at the cavity's edge, resulting in a reflected shock effect, which IXPE highlighted.
A Composite View: Unifying X-ray Data
The composite image integrates IXPE's data with historical observations from two other X-ray telescopes: NASA's Chandra and the European Space Agency's (ESA) XMM-Newton. Low-energy X-rays are represented in yellow, while high-energy X-rays detected by Chandra and XMM-Newton are shown in blue. The starfield in the image was sourced from the National Science Foundation's National Optical-Infrared Astronomy Research Laboratory (NOIRLab).
