LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars（图）
LIGO Virgo first detection gravitational waves produced colliding neutron stars
2017/10/26
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...
Gravitational Waves+New Clues From Space Reveal New Way To Make A Black Hole（图）
Gravitational Waves Space Make A Black Hole
2017/10/26
For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space -- the birt...
Gravitational waves carry information about their origins and about the nature of gravity that cannot otherwise be obtained. Physicists on the LIGO and Virgo teams concluded that, as with LIGO’s first...
International Symposium on Gravitational Waves（ISGW2017）
International Symposium Gravitational Waves
2017/3/28
The direct detection of gravitational waves opens a new window to explore our Universe and indicates the coming of a new era of gravitational wave astronomy. In 2015, the KITPC program on “The Ne...
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the Sun, according to a new study led by a scientist at the National Cente...
Newly dedicated observatory to search for gravitational waves
Newly dedicated observatory gravitational waves
2015/5/25
Seeking to expand how we observe and understand the universe where we live, the National Science Foundation today helped dedicate the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) at...
BICEP2 and Planck joint study: Gravitational waves remain elusive
BICEP2 Planck joint Gravitational waves remain elusive
2015/3/4
A new joint analysis of data from two South Pole-based experiments--the BICEP2 telescope and the Keck Array, both supported by the National Science Foundation--and the European Space Agency's Planck s...
Supernova Blast Waves in Low-Density Hot Media: A Mechanism for Spatially Distributed Heating
structure supernova remnants
2014/12/24
Most supernovae are expected to explode in low-density hot media, particularly in galactic bulges and elliptical galaxies. The remnants of such supernovae, although difficult to detect individually, c...
Dipole Collapse and Dynamo Waves in Global Direct Numerical Simulations
Dipole Collapse Dynamo Waves Global Direct Numerical Simulations
2012/2/23
Magnetic fields of low-mass stars and planets are thought to originate from self-excited dynamo action in their convective interiors. Observations reveal a variety of field topologies ranging from lar...

Magnetic Fields Relativistic Particles Shock Waves Cluster Outskirts
2011/10/20
It is only now, with low-frequency radio telescopes, long exposures with high-resolution X-ray satellites and gamma-ray telescopes, that we are beginning to learn about the physics in the periphery of...
Detecting relic gravitational waves in the CMB: A statistical bias
Detecting relic gravitational waves statistical bias
2011/10/13
Analyzing the imprint of relic gravitational waves (RGWs) on the cosmic microwave background (CMB) power spectra provides a way to determine the signal of RGWs. In this Letter, we discuss a statistica...
Rossby waves and polar spots in rapidly rotating stars: Implications for stellar wind evolution
magnetic fi eld – Stars: activity – Stars: starspots – Stars: oscillations – Physical data and processes: Magnetohydrodynamics
2011/10/10
Rapidly rotating stars show short-period oscillations in magnetic activity and polar appearance of starspots. The aim of this paper is to study large-scale shallow water waves in the tachoclines of ra...
