Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
星系合并 SMBH 恒星物体演化 多质量 直接N体模型
2023/11/13
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Fill-ins and Positive Mass theorem
填充 正质量定理 AH流形
2023/5/15
In this talk, we shall use fill-in to give a new description of the positive mass theorem. By using this, we shall show that PMT on AH manifolds implies PMT on AF manifolds. This talk is based on the ...
New findings reveal the most detailed mass map of dark matter（图）

2023/6/29
For millennia, humans have been fascinated by the mysteries of the cosmos. From ancient civilizations such as the Babylonians, Greeks, and Egyptians to modern-day astronomers, the allure of the starry...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On the residual Monge-Ampère mass of plurisubharmonic functions with symmetry
对称性 多次调和函数 残余 蒙日-安培质量
2023/4/13
In this talk, we will study the residual Monge-Ampère mass of a plurisubharmonic function with isolated singularity at the origin in C2. We proved that the residual mass is zero if its Lelong number i...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rigidity of non-compact static domains in hyperbolic space via positive mass theorems
正质量定理 双曲空间 非紧致 静域刚性
2023/4/14
We single out a notion of staticity which applies to any domain in hyperbolic space whose boundary is a non-compact totally umbilical hypersurface. For (time-symmetric) initial data sets modeled at in...
Unlike electrons, quarks cannot wander freely in ordinary matter. They are confined by the strong force within hadrons such as the protons and neutrons that make up atomic nuclei. However, at very hig...
In a milestone that will bear on future discoveries in nuclear and particle physics, today an international team including scientists from MIT announced that they have established a new upper limit on...

New research reveals remarkable resilience of sea life in the aftermath of mass extinctions
marine ecosystem biodiversity climate change
2021/8/5
Pioneering research has shown marine ecosystems can start working again, providing important functions for humans, after being wiped out much sooner than their return to peak biodiversity.
The LHCb collaboration has measured a difference in mass between two particles of 0.00000000000000000000000000000000000001 grams – or, in scientific notation, 10-38 g. The result, reported in a paper ...

Sentinels ocean acidification survived Earth last mass extinction
2020/10/10
Two groups of tiny, delicate marine organisms -- sea butterflies and sea angels -- were surprisingly resilient in the face of dramatic global climate change and Earth's most recent mass extinction eve...

Mass extinction land sea biodiversity 250 million years ago simultaneous
2019/12/13
Some 250 million years ago, simultaneous mass extinctions of marine and terrestrial life occurred in an event known as the End-Permian. Or so scientists believed.New research led by Colby College geol...
