Q&A: X-ray Astronomy

Q:
Do xrays from distant objects show a redshift that scales with distance similiar to light's? Is Chandra capable of detecting such? Is there any evidence that neutrinos show a redshift?

A:
X-rays detected with Chandra can and do show redshifts just like visible light. See http://chandra.harvard.edu/resources/faq/x-ray/x-ray-10.html

Neutrinos are a different story, we have enough difficulty just detecting them, from places as nearby as the Sun or the Earth's atmosphere. They may experience a redshift (or loss of energy) as they travel through space, resulting either from interactions with other particles (rare but does occur) or from the expansion of space.

A brief description of 3 types of redshift may be found at:
