The lab observes black holes in X-rays and also develops instruments to be carried on satellites.

AboutAbout the lab
X-ray observation and instrument development, side by side
The Noda Lab observes high-energy objects such as black holes in X-rays, and at the same time develops instruments to be mounted on satellites.
Associate Professor Noda joined the Astronomical Institute at Tohoku University in April 2024 and established the lab as an X-ray astronomy lab.
Supermassive black holes lie hidden at the centers of galaxies, and when they swallow surrounding matter, they emit intense electromagnetic radiation as active galactic nuclei.
Because X-rays are absorbed by the Earth's atmosphere and do not reach the ground, they are observed from space by placing detectors on satellites.
Key terms
- supermassive black hole
- A black hole at the center of a galaxy, with a mass from one million to one billion times that of the Sun
- active galactic nucleus
- A state in which a supermassive black hole swallows matter and emits electromagnetic radiation brighter than its entire host galaxy, along with high-speed plasma outflows
- X-ray microcalorimeter
- One of the detectors on the X-ray astronomy satellite Hitomi. Its sensor is used after being cooled to an extremely low temperature of 50 millikelvin
ResearchResearch themes
The lab aims to clarify how the radiation and outflows of active galactic nuclei are produced, by observing X-rays generated in the immediate vicinity of supermassive black holes. It also develops the satellite-borne X-ray detectors used for these observations.
*Illustrative imageX-ray observations of active galactic nuclei
When a supermassive black hole at the center of a galaxy swallows matter, an active galactic nucleus appears, emitting intense electromagnetic radiation and high-speed plasma outflows. The lab tries to clarify how this radiation and these outflows are produced through X-ray observations.

Associate Professor Noda and colleagues have developed detectors for Hitomi and XRISM. For Hitomi, he contributed to the thermal design and cooling system of the X-ray microcalorimeter, and for XRISM, he led the development of the X-ray CCD camera.
