China’s first X-ray space telescope: ‘Insight’ will study evolution of black holes, gamma-ray bursts and more

Beijing:
China’s first X-ray space telescope allows scientists to study the evolution of black holes, strong magnetic fields and gamma-ray bursts has been successfully launched on Thursday.

The High Definition Modulation Telescope (HXMT) weighing 2.5 tonnes is dubbed ‘Insights. A Long March-4B rocket lifted the Jiuquan Satellite Launch Center Space Telescope in the Gobi Desert in northwest China and placed in an orbit 550 kilometers above the ground.

The telescope will also help scientists study the use of pulsars for space navigation and search for bursts of gamma rays corresponding to gravitational waves, state news agency Xinhua reported.

“Insight” is the idea of the wisdom and efforts of several generations of Chinese scientists. It intends to advance in the development of astronomy space and improve space technology X-ray detection in China.

Because it carried a trio detector – the high energy X-ray telescope (EST), the medium-energy X-ray (ME) telescope and the soft X-ray (LE) telescope – the “Insight” can be considered a Small observatory in space.

These sensors cover a wide range of power from 1 keV to 250 keV, said Lu Fangjun, head of payload design, according to the report.
Based on the demodulation technique first proposed by Li Tipei, academician of the Chinese Academy of Sciences (CAS) in 1993, it has a total detection area of more than 5000 square centimeters, the largest in the world in its group energetic.

“Because it has a larger detection area than other X-ray sensors, HXMT can identify more sources of known characteristics,” said Xiong Shaolin, a scientist at the Institute of High-Energy Physics CASE.

Chen Yong, chief of LA design, said X-rays of lower energy generally more photons, so a telescope based on a focusing technique is not suitable for observation of very bright objects X-ray emitters soft because many photons Both will lead to overexposure.

But HXMT will not have this problem because of its photon collimators instead of concentrating diffuse.

“No matter the brightness of the sources, our telescope will not be blinded,” said Chen.

Shuangnan Zhang, senior scientist HXMT, told the satellite developers have found a set of high-energy HXMT detectors, originally designed to protect background noise caused by unwanted particles, could be adjusted to observe gamma rays.

The satellite observation group is driven by the new creative function up to 3 MeV and a large spectrum of energy, said Zhang.

The first China Cargo spacecraft has successfully coupled with an orbiting space laboratory in April. It was a key event in China’s goal to have its own space station crew in 2022.

China has established a laboratory “Lunar Palace” on Earth last month in order to simulate a moon environment and accommodate students up to 200 days, as the country prepares its long-term goal of humans natural satellite send .
