LIGO detects gravitational waves for third time
LIGO detects gravitational waves third time
2017/7/21
The collision of a pair of colossal, stellar-mass black holes has made itself heard, nearly 3 billion light years away, through a cosmic microphone on Earth.
On Jan. 4, the Laser Interferometry Gravi...
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...
LIGO begins next search for gravitational waves

Statement from National Science Foundation Director France Córdova regarding news that, after a series of upgrades, researchers have reactivated the twin detectors of the Laser Interferometer Gravitat...
Gravitational waves detected from second pair of colliding black holes
Gravitational waves second pair colliding black holes
2016/6/22
On Dec. 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time.
The gravitational waves were detected by both of the twinLaser ...
Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be “seen” by looking at the stars. The new model, developed in...
Reconstructing the massive black hole cosmic history through gravitational waves
massive black hole cosmic history gravitational waves
2010/12/21
The massive black holes we observe in galaxies today are the natural end-product of a complex
evolutionary path, in which black holes seeded in proto-galaxies at high redshift grow through
cosmic hi...
Polarization modes for strong-field gravitational waves
Polarization modes strong-field gravitational waves
2010/12/20
Strong-field gravitational plane waves are often represented in either the Rosen or Brinkmann forms. These forms are related by a coordinate transformation, so they should describe essentially the sam...
Strong lensing of gravitational waves as seen by LISA
Strong lensing of gravitational waves seen
2010/12/21
We discuss strong gravitational lensing of gravitational waves from merging of massive black hole binaries in the context of the LISA mission. Detection of multiple events would provide invaluable inf...
Hierarchical Hough all-sky search for periodic gravitational waves in LIGO S5 data
Hierarchical Hough LIGO S5 data periodic gravitational waves
2010/3/18
We describe a new pipeline used to analyze the data from the fifth science run (S5) of the LIGO detectors to search for continuous gravitational waves from isolated spinning neutron stars. The method ...
Gravitational Waves I: Basic Emission Equations
Einstein gravitation theory gravitational waves
2010/3/17
Using the Einstein gravitation theory we show how to obtain the basic equations which predict the gravitational waves. This paper was written to graduate and post-graduate students of Physics. We dedu...
