How to solve it?

In order to understand the dynamic growth mechanism of the super large black hole, Xu made use of the computer software to make the dynamic mass growth more intuitive.

"This is a supermassive black hole discovered by the Chandra Roentgen Ray Observatory." "It exists in the core of most galaxies, almost 13.1 billion light-years away," Xu said solemnly, handing over a piece of information to several people

"This means that this supermassive black hole must form rapidly after the first stars die." Xu stopped for a moment and continued, "however, we have not found enough dust and gas in the early universe to explain this rapid growth."

Then, Xu mang took out another document and handed it to the five people, saying, "this is the early quasar report data. Twelve of them have hydrogen clouds with amazing density. These hydrogen clouds are identified by their unique luminescence under ultraviolet light."

Eh?

Hydrogen cloud?

What do you mean?

The five graduate students looked at Xu Mang, confused about why he took out the hydrogen cloud.

"Don't worry."

"I haven't spoken yet." "These clouds of cold, dense hydrogen are billions of times the mass of the sun, forming rings around early galaxies that extend about 100000 light-years from the center," Xu said calmly

"We can draw a conclusion that these gas halos are closely linked to galaxies and provide a perfect source of food for the rapid formation of stars and the growth of supermassive black holes." "In other words, there is enough food in the primitive galaxies to sustain the growth of supermassive black holes and powerful star formation," Xu said

"Of course, all this is my guess. If you want to know more about the formation code of supermassive black holes, you need to study the details of primitive gas clouds." Xu mang looked up at the graduate students in the Physics Department of the five person university and asked with a smile, "what's the problem?"

"..."

"..."

"..."

"..."

for a while,

the five people suffered 10000 points of critical damage in their hearts. Why did a puzzle that puzzled everyone for a long time could not live for half an hour? He just looked through the data he had submitted and found the supporting information from it.

Why didn't you discover it?

This is...

is this the strength gap?

"Continue to study... Adjust your thinking and think about ancient gas clouds." "Give me a complete research report in 15 days, you can go back now, by the way... If you want to borrow any astronomical equipment, give me a report, and I will contact them at home."

For a moment,

watching the five graduate students leave, Xu mang sighs, and quickly picks up the phone on the side and calls Fang Jun, director of physics at Fuda University.

"Hello?"

"Guess who I am?" Xu mang asked with a smile: "guess right, no reward."

"..."

"Xu mang?" Fang Jun said helplessly: "call me for what? In other words, you are also the person in charge of Xu Yang Research Institute. In the future, don't say "guess who I am". It's too unstable. "

"Cough!"

"Don't forget your original intention." Xu mang awkwardly said: "director Fang, is the fractional line of Physics Department of Fuda very low? The ten graduate students you asked me to come here don't seem to be very good. They all feel a little confused. "

"..."

"you can't use your own template to evaluate each other. You... You have not had much class. As a result, you have been promoted to a professor within a year, and you have been mixed up as an associate director. Not everyone's experience is the same as you." Fang Jun said with a wry smile: "cultivate well, I still have something to do... Hang up first."

Bang!

Hang up directly.

Xu mang almost did not die of anger, when he was hung up by others?

No...

he is often called by Xiao man.

...

as time passed by, two more days passed.

Xu mang basically completed the scattering problem of uncharged neutrons, and a neutron diagnostic device with independent property rights was born. However, Xu mang did not report this device. He was always worried that he could not solve the problem that the neutral neutrons in the real sense would not be constrained.

Sorry,

the pride of the heart can't accept such a situation.

Of course, too much pride eventually ends in failure. Xu mang knows this truth. In his efforts to solve the problem that uncharged neutrons will not be constrained, Xu mang also speeds up the relevant simulation tests on the neutron diagnostic device.For this reason, Xu mang has developed a diagnosis system. When the neutrons in the field of view of the neutron diagnostic device are scattered, the proportion of scattered neutrons can be checked, so as to clearly know the number of uncharged neutrons at this time, and these data will be displayed in front of the scientific community in a very intuitive way.

"Hiss..."

"it's not enough." Xu mang frowned, and temporarily modified the system, adding emission spectrum, yield, space, time distribution, radiation dose and other measurement data, in order to diagnose the comprehensive impact of neutral neutrons.

At this time,

the neutron diagnosis device is truly completed.

"Hello?"

"Wife?" Xu mang received a call from Xiaoman and asked curiously, "are you going to the capital for a meeting? What meeting do you have

"Alas..."

"the high-tech industry technology conference is the big men of some high-tech industries." Yang Xiaoman tooted his mouth, with a trace of displeasure in his tone: "I'm not compatible with them. I don't want to go at all, but this is an invitation letter from the official."

"Just go. I'm going to America in five days." Xu mang said calmly: "flying from place to place, is not our daily life?"

"You don't know!"

"They were very dissatisfied with my monopoly on photoresist materials, and then... I monopolized flexible materials." Yang Xiaoman said angrily: "they are more dissatisfied, husband... What if they unite to bully me? After all, I'm on my own. "

Suddenly, Xu mang fell into silence, just a little time, said with a smile: "don't panic, you still have me!"

"Well!"

"By the way..." Yang Xiaoman suddenly thought of a thing and asked seriously: "Christmas Eve, Christmas, Valentine's day, you didn't accompany me... What should you do?"

"Hello?"

"Hello?"

"What's the situation? Why is there no signal? " Looking at his own full grid of signals, Xu mang opened his eyes and began to talk nonsense: "these communication companies... Unexpectedly, the service quality is so poor."

Bang!

Hang up,

take a long breath, Xu mang has a sense of survival after a disaster, it's dangerous... Almost fell into the trap of Xiaoman, but she has to face her requirements when she comes home. What should I do?

There was a knock on the door, and then Chuanxiao came in with a can of tea in his hand.

"Xu mang."

"Have a drink of this tea. You'll fall in love with it." Brother Chuanxiao handed the can of tea to Xu Mang and said with a smile, "this is a bribe."

"Ah?"

"What do you want to do when you suddenly send me a pot of tea?" Xu asked curiously.

"I have a nephew who has a master's degree in materials from HKUST." Chuanxiao said: "he is worried about looking for a job. He is a very serious person. He doesn't want to enter any enterprise. Instead, he wants to work in the Research Institute. Can you give me a chance?"

"Master's degree from materials department?" Xu mang was stunned for a moment and said with a smile: "come on! I just told you a plan. Isn't there a piece of land next to us? My wife has already taken it. In the future, she will build a material Research Institute on the edge. "

"Let him come first?"

"Yes

"It happens that antiferromagnetic topological quantum materials need him." "I think the quantum materials group is finished... There has been no movement for several days. I'm afraid all five people are desperate," Xu said

"You give it too much difficulty." Chuanxiao said, "it's difficult to go to hell. They're not you."

After reading the Research Report on Xu Mang's desk, he asked curiously, "have you finished the neutron scattering problem?"

"This is a neutron diagnostic device, and I don't have the ability to solve the real physical phenomena of neutron scattering." Xu sighed blankly, his face showed a trace of helplessness: "maybe it can be solved at some time in the future, but it is definitely not now. Now I can't find the breakthrough point to solve the problem."

"Or...

" you should report this first. The circulation No.2 is just an experimental platform, and there will be No.3 and No.4 coming out in the future. You can solve this problem in your spare time, but... Now you need to ease their urgent needs. " Chuanxiao said.

Not to mention,

sounds very reasonable.

Finally,

Xu mang called academician Zhou.

"Hello?"

"Academician Zhou... Are you busy?" Xu mang asked with a smile.

"Xu mang?"

"OK..." academician Zhou received a call from Xu Mang, and was surprised.

"Oh... It's OK." Xu mang carefully said: "academician Zhou... I want to ask, circulation 2 project is urgent? Is time pressing? "

"Time is tight.""It's almost half a year from now, but we still have some problems to solve." Academician Zhou said with a wry smile, "we will wait for you to simulate the system and neutron scattering."

Yeah!

The simulation system is still waiting!

Xu mang remembered that he was given another task, the early stage simulation system of circulation 2. Now, the time is still tight. However, this simulation system should be developed after returning from the United States of America.

"Academician Zhou..."

"let me tell you a message." "I can't solve the physical phenomenon that charged neutrons are not constrained," Xu said cautiously. "I need the particle collider to carry out relevant experiments and find a solution from the data."

Br > "but I found a way out of the neutron scattering device for the time being." Xu said.

Academician Zhou was stunned for a moment. He had already heard it wrong. He asked in a hurry: "do you... Do you find a way to solve the problem of neutron scattering in thermonuclear fusion?"

"Yes

"Temporarily... Temporarily found!"
