XRISM will unlock the deepest secrets of the universe

If all eyes are currently on the moon, which is perfectly normal given what’s happening there, let’s not forget that on Saturday, JAXA will launch a space observatory at X.XRISM, which is the name of a major project being undertaken in collaboration. With Japan, Europe and the United States. It is designed to observe the most energetic events in the universe. In doing so, it will reveal the evolution of the universe and the structure of space-time.

Japan’s space agency, JAXA, is preparing to launch the space observatory on Saturday morning X rayX ray and spectroscopy (XRISM) on board a rocketrocket H-IIA from Tanegashima Space Center, Japan. This launch will be broadcast live on JAXA YouTube channel. It is scheduled to take place Friday night to Saturday at 2:34 am French time.

This mission is being carried out in international cooperation with the US space agencies, Europe and Japan. It was designed to replace the Hitomi satellite, which was lost a few weeks after its launch in February 2016. XRISM is supposed to operate for at least three years, from an altitude of about 550 kilometers! For the European Space Agency and NASANASATheir participation in XRISM is interesting because it forms a valuable “bridge” between X-ray missions such as the European XMM-Newton and the US Chandra and future X space observatories such as Athena (ESA), which are expected to launch in the late 2030s.

X-ray observation

This observatory contains two tools. One to measure the temperature and dynamics of the objects emitting X-rays (Solve) and a tool for imaging extended celestial sources that emit X-rays and their environment.

As mentionedastronomerastronomer Matteo Guenazzi, ESA project scientist for XRISM, X-ray astronomy allows us to study the most energetic phenomena in the universebeingbeing. It holds the key to answering important questions ofAstrophysicsAstrophysics Talk: How do the largest structures in the universe evolve, and how ThemeTheme which we eventually composed was distributed in UniverseUniverseand how galaxiesgalaxies formed by black holesblack holes huge in their center “.

Did you know ?

In return for providing the instrumentation and science advice for the XRISM mission, 8% of the available observation time will be allocated to the ESA space observatory. This will allow European scientists to suggest X-ray observable celestial sources.

The interest of the observatories operating in X is that they show us the most violent phenomena in the universe, that is, the most energetic and hottest explosions in the universe. This includes GasGas So warm that envelops the largest lumps buildingbuilding Universe: groups of galaxies.

Answers to basic questions

XRISM will provide some answers and answer many outstanding questions including those related to the formation and evolution of the universe (a measure of the total mass of galaxy clusters) and how the universe is produced and distributed. chemical elementschemical elements. By studying the X-rays emitted by the gas, XRISM will discover what ” mineralsminerals » (elements heavier thanhydrogenhydrogen and theheliumhelium) it contains, and will map out how it enriches the universe.

Finally, to the great delight of cosmologists, XRISM will take a closer look at individual X-ray-emitting objects to venture into the universe. physicalphysical Basic. The mission will measure X-rays emitted by incredibly dense objects such as supermassive black holessupermassive black holes Origins located in the center of some galaxies. This will help us understand how objects distort the space-time around them and how they affect their host galaxies through ” windwind » of particles ejected in gearsgears close to that light.
