Columbia Professor Brian Metzger helped other astronomers interpret their observations of the unexpected stellar event.

标量粒子是一类自旋为0的粒子。它们能与核子耦合（coupling），亦即相互作用，彼此影响或交换能量和动量。观测到标量粒子将极大地丰富人类对宇宙及潜在作用力的认识。但目前唯一被确认的标量粒子只有希格斯玻色子（Higgs boson）。

Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray ...

A distant neutron star unexpectedly reawakened, unleashing a powerful X-ray surge that may reveal how the universe’s most ...

Some of the densest objects in the universe are neutron stars. Neutron stars are the remnants of stellar cores left behind when a star has gone supernova. The only known objects denser than neutron ...

The collision of two neutron stars around 130 million light-years from Earth, and the unique physics this merger created, may have shed new light on dark matter. Axions have never been directly ...

Forget archaeologists and their lost civilizations, or paleontologists with their fossils—astrophysicist Heloise Stevance studies the past on an entirely different scale. When astronomers catch a ...
