People of X-IFU

"By improving spectral and angular resolutions, with such a large effective area, NewAthena X-IFU will represent a major step for X-ray astronomy."

Jiri Svoboda

Astronomer at the Astronomic Institute of the Czech Academy of Sciences

"Every major leap in our observing capabilities in the past has led to unexpected discoveries, and I hope nature will not fail to surprise us also this time around."

Aurora Simionescu

Co-PI & Research Scientist at SRON, Netherlands

"Once NewAthena X-IFU will be launched, observation of the sky will be taken to a whole new level. The instrument should be able to reveal the origin of the universe!"
