FAST, Five-hundred-meter ApertureSphericalradioTelesco - the full name is the 500-meter Aperture Spherical Radio Telescope.
Of course, it has a more popular name, "Eye of the Sky".
As the world's largest radio telescope, and after the collapse of Arecibo, it is the world's only radio telescope with a diameter of more than 300 meters. It is a well-deserved national treasure and even the top observation tool in the entire astronomical community.
Especially for the observation of pulsars, hundreds of pulsars have been discovered in just a few years, greatly filling the pulsar database.
The so-called pulsar refers to a neutron star that rotates at high speed and continuously emits electromagnetic signals. It is generally believed that it is formed by a supernova explosion, but the new theoretical framework "accretion-induced collapse" also shows that supernova explosion is not the only way it is formed.
.
Of course, FAST's capabilities go far beyond "targeting" pulsars. Its clever adjustable angle design, ultra-large reflector, and highly sensitive feed make it extremely good at observing neutral hydrogen regions.
Three years ago, the country announced that FAST would be fully open to astronomers around the world.
Today, many astronomical teams from all over the world have come to the depths of the western mountains to cooperate.
…
"Samuel, can you ask Sita to put two more pieces of candy for me next time?"
In the international cooperation base across the mountain from FAST, Li Lei was holding coffee that was bitterer than traditional Chinese medicine, with a constipated look on his face: "Didn't you say that Italians like sweets? Why did you do the opposite?"
"Putting sugar makes you gain weight."
Samuel held the coffee, leaned on the desk, and took a sip without changing his expression.
Their office is not big, with only five or six spaces. Now, in addition to the two of them who are postdoctoral fellows, there is also Samuel's Sita, and a graduate student girl from Nanjing University working here with their mentor.
It was the weekend, and they were still staying in the office. On the one hand, they had no hard needs, and on the other hand, they also had to keep an eye on the data of a new suspected pulsar - here, although the discovery of a pulsar is nothing, it is something.
Discovery is always exciting for astronomers.
The West Tower was bought by Samuel. He comes from Venice, a leather goods family, and his family is well off. His father opened a factory in Wenzhou. He applied to FAST after studying for a doctorate in astronomy at the Sapienza University of Rome.
The last time he robbed Sita, everyone in the office "helped" him, so he kept his promise and made Sita a waiter in the office.
Li Lei is different from him. He comes from P University and has been working here for six years. He used to follow his tutor, but now he is "working alone". Although he has published a lot of papers, he always feels that they are not interesting enough.
Being engaged in astronomy, he must be able to survive loneliness. After all, he has been staying in this mountain nook for several years, and his wife has no objection, so he is naturally happy to stay.
The two of them were chatting casually. Next to them, Chen Xiang, a junior student from NTU, was holding a tablet and watching videos. They were located in the core area, so mobile phones couldn’t be used, and wifi couldn’t be used either. However, it was no problem to set up a hidden hotspot indoors.
of.
After all, the signal of wifi is almost gone even if it is separated by a wall, let alone a mountain.
"Teacher Li, we should change to the ETA system here, right?" Chen Xiang raised her head. She held up the tablet with a look of great interest: "Look at the latest display of Jizhi Technology. The twin tower combination is really strong.
.”
"It depends on whether the higher-ups are willing to spend the money. Now we can't even match Aita's computing power." Li Lei said and glanced at his computer monitor.
——As a key project, FAST has high demand for AI, computing power, and algorithms, so not long after Aita went online, they enjoyed key care.
However, as JiZhi Technology provides more and more services, their computing power allocation is becoming more and more limited. It is only now that Aita has access to a quantum computer.
"Huh? Do you want to mention your computing power?"
Li Lei immediately sat upright and saw that the analysis progress, which was only 10% five minutes ago, was now completed. He immediately shouted: "Damn it, my computing power has really improved!"
The other two men immediately stood behind him.
On the monitor, it showed that the data analysis had indeed been completed.
Li Lei exhaled softly and prepared to click on the report.
Just then, the phone on the table suddenly rang, startling him.
Li Lei took the phone and opened the report at the same time: "Hello, who is this?"
A young voice came from the phone: "Hello, FAST? I'm Ye Ming."
"Well, yes...Ye Ming? Do we know each other?" Li Lei focused all his attention on the report.
An embarrassed smile came from the phone: "Okay, it seems like we really don't know each other..."
"Wait a minute." Li Lei was stunned for a moment.
At this moment, the two people beside him also looked at him in shock.
Both of them heard the word "Ye Ming" in his mouth.
Li Lei's heartbeat accelerated instantly.
"Ye Ming...is this Professor Ye Ming from the provincial government?"
"Well, it's me, what do you call me?"
"Ah... Hello, Professor Ye..." Li Lei stood up instantly, took several breaths and then suppressed his excitement: "My name is Li Lei, and I am an associate researcher at the FAST International Collaborating Laboratory."
"Hello, Mr. Li." On the phone, Ye Ming's voice was filled with a smile: "It's like this. In a certain aerospace project, we conducted a study on various planets, dwarf planets, and massive asteroids in the solar system.
A unified orbit and predictions and modeling... found that it matched the description of a previous paper on gravitational anomalies."
Li Lei took a deep breath, his mind began to spin rapidly, and he nodded immediately: "Yes! I have an image of the paper in Physical Review Letters. TNO has gravitational anomalies, and it is predicted that there are undiscovered massive objects in the outer solar system."
"Yes, so after modeling, we found that the current position of FAST is exactly facing that star field. Can you do me a favor and adjust the position of FAST a little, and first aim at a star numbered FA8798-5452 to collect
Data, and then adjust the position every hour. I will send you the specific angle through Aita who authorized you."
Following Ye Ming's voice on the phone, Li Lei also saw that the Aita terminal on his computer also automatically popped up a dialog box.
His heartbeat began to beat violently at this moment!
As an astronomer, he understood Ye Ming's intention instantly.
——This is to hope that the Sky Eye will track and collect the deep space electromagnetic signals of a certain trajectory, and analyze whether there are undiscovered massive celestial bodies interfering or interfering!
Once again, I think of the astronomical community’s hypotheses about this unknown celestial body…
If it's an undiscovered planet, forget it. If it's really a black hole...
Li Lei clenched his fist instantly!
"Okay! Right now!"
"Well, thank you in advance, because the window period is a bit short, so I have to call you first. Please tell me what follow-up cooperation procedures are required, and I will make up for it."
"It's okay, it's okay. If you just say a word, who wouldn't dare to cooperate..."
After hanging up the phone, looking at the two people beside him, he laughed loudly!
"Let's do it!"

After Ye Ming hung up the phone, he called Director Niu again.
After the call was connected, he told Director Niu that he wanted to use FAST, and by the way, he also told the other party that he did not like to change partners.
On the phone, Director Niu's voice was a little surprised: "Why did you suddenly think of using FAST?"
Ye Ming laughed: "Then I'll go find Lao Mei and use Harper or Weber?"
"...Are you hacking in?"
"They will let me use it even if I don't do it..." Ye Ming laughed and said: "No more nonsense, I want to use it anyway, and that Li Lei... let him be responsible."
This Li Lei is a postdoctoral associate researcher. Judging from his previous work, he has been patrolling the target sky. Many of the data Ye Ming obtained came from his projects.
In addition, I received this call from myself during the holidays, which means that the two of them are destined.
Since we are destined, there is no need to cause any messy things.
"No problem, but you have to tell me what the result is."
"What should I tell you? I said it might be a wandering black hole in the solar system?"
Ye Ming heard a gasp of air coming from the other side of the phone.
Ye Ming was very satisfied with Lao Niu's performance - it was obvious that Lao Niu still had basic scientific literacy.
If a stray black hole is really discovered in the solar system, then of course, the Nobel Prize will definitely not escape - this is not a matter of discovery, but a matter of verification!
Nowadays, black holes are confirmed celestial bodies, but "low-mass" and "wandering" black holes have always been hypotheses. If it is really proven... it means that the model of celestial bodies in the universe will be greatly improved.
"real or fake?"
"Director Niu, I can tell you are not engaged in scientific research." Ye Ming joked with a smile.
"..."
…
After hanging up the phone, Ye Ming breathed out softly.
Then, he looked at Qi and Mo sitting opposite.
Qi and Mo also looked at him, with smiles on their faces. In short, it was a bit strange.
"It's a pity that you don't study astronomy." Ye Ming chuckled and said, "Otherwise, you would have won at least two top journals."
"That's not surprising!" Qi Yumo waved his hands: "Tomorrow's developer conference, will you be there by yourself, or..."
Qi Yumo glanced at Eta, who was sitting quietly next to him.
Ye Ming began to ponder.
This time, the ETA Developer Conference was attended by various well-known game companies and Internet companies. Whether it was Goose Farm, Pig Farm or Alibaba, all of them were present, and judging from the candidates sent, there were not many companies among them.
of president-level executives.
It can be said that... the face is still enough.
Logically speaking, it is time for Ye Ming, the CTO, to formally come forward.
But when I think about how sometimes I can’t hold it back...
"It's better for Eta to go and then she will cooperate with you."
Qi Yumo took a gentle breath, and his face turned a little red due to excitement: "Then it's true that I go?"
"Well, anyway, you have been preparing, and no one in the company is better than you in interacting with Aita." Ye Ming looked at Qi and Mo, with a smile on his lips: "Go boldly, just pretend to be a cross.
