These events are not witnessed by traditional astronomy because traditional astronomy depends on light signals. With gravitational wave detection, we get a whole new perspective of the universe and the kind of objects that exist in it. Even detecting gravitational waves from events that produce light...
How big is a gravitational singularity? What is accretion of planetesimals? What do the variables in the nebular hypothesis mean? What is gravitational time dilation? What is hydrostatic equilibrium in astronomy and astrophysics? Why is the gravitational force zero at the center of the Earth?
In less than 100 seconds, Ben Stappers of the University of Manchester in the UK explains how gravitational waves are the astrophysical equivalent of throwing a stone into a pond: they appear as ripples in space–time. He also explains that gravitational waves have been predicted to exist ...
How big is a gravitational singularity? What is the gravitational force of the black holes? How big is a singularity in a black hole? What is the Schwarzschild radius of a black hole? What is gravitational wave astronomy? What is in a black hole? What is behind a black hole? What is ...
Scientists have finally found the gravitational wave background, ushering in Astronomy 2.0. It's literally a whole new way to look at the universe.
Such a signal could tell us something about core-collapse supernovas that "traditional astronomy" that relies on electromagnetic radiationcan't. It could tell us the nature of the stellar remnant created in the supernova, namely, whether it is a black hole or neutron star. ...
“Even though so far the data only provides us with a first hint of the existence of low-frequency gravitational waves, it is still very exciting for us to work with them. This is because such waves could be produced by various processes that occurred in the early universe. We can now...
黑洞-中子星系统或者双中子星系统可以借由多信使天文学(multi-messenger astronomy)里的电磁对应体(electromagnetic counterparts)来研究引力波相对电磁波的一些特殊性质. 这些都使得对于黑洞物理和中子星相关的核物理不再局限于纯粹的理论猜测而进入到实际验证阶段. 引力波物理不仅对以上引力物理具有重要意义, 也对粒子物理...
Ye plans to study astrophysics(天体物理学) in college,especially gravitational-wave(引力波) astronomy. "It's a very young field," she said. "It would be really nice to grow up with the field as it develops."(1)Why did Christine Ye win the award? BA.For finding a new neutron star...
Thanks to the many binary BH events detected so far with many more expected in the next few years, gravitational-wave astronomy is about to become a population study. Currently hierarchical Bayesian analysis combining astrophysical formation models and PBHs may only constrain the fraction of a putati...
