He knew that there was something very important going on with LIGO. E-mail comments or questions to the editors at letters@northwestern.edu. Take a 1.3 billion-year journey with LIGO scientist David Reitze and see how the gravitational waves made it to Earth. EXd.write("

Print this story. While LIGO scientists analyzed the data and prepared scientific papers on the detection of gravitational waves, news of the discovery began to leak out. “If only I had a little bit of time to read through the emails.” But the day passed. “People were stunned at how good this signal was,” says Reitze.

Now we have to explore it.”, Northwestern University   1603 Orrington Avenue, Suite 200, Evanston, IL 60201   Phone: 847.491.5000   letters@northwestern.edu. We’re actually starting a new kind of exploration of the universe.”. With the potential for even greater detection on the immediate horizon, it’s a heady time for scientists who study the cosmos. “A lot of people came to our defense and said, ‘Don’t rush them; let LIGO do their due diligence,’ ” explains Reitze. Finding gravitational waves is “really a triumph of science and human ingenuity and tenacity,” says Reitze, a laser physicist who has been involved with LIGO since 1996.

We’re looking at the data. Because LIGO had just started up after a five-year upgrade, most thought the event was a test. “It happens that my husband [Fred Rasio] is also an astrophysicist at Northwestern — I couldn’t hide certain things from him, like my work schedule, which became impossible very quickly.

Once he confirmed that there were no blind injections that day, he concluded the detection was real. What we saw was unique. Windows to the Universe. Thematic Study. “We were overwhelmed by the media attention,” says Reitze.

We’ll have something to say in a few months.’ ”, In the end, once the LIGO team submitted the paper to Physical Review Letters, the world’s premier physics letter journal, somebody managed to get a copy of it. It is elaborated using examples of properties, including some already on the World Heritage List or national Tentative Lists, Starlight Award - Jameson Notodofilmfest 2011, III Starlight Conference - New Zealand 2012, New Brochure of UNESCO`s MAB Programme partnership, Starlight at the 39th session of the World Heritage Committee, International declaration warning about the effects of blue-rich white light, Flyer - Starlight Initiative in partnership with the UNESCO MAB Programme, Montsec - Starlight Destination and Reserve. See “Einstein and Gravitational Waves,” page 19.).

The Starlight Initiative is collaborating with the IAU Working Group. The discovery was made possible by the enhanced capabilities of Advanced LIGO, an ongoing major upgrade to the observatories that is increasing the sensitivity of the instruments so that, for example, LIGO can now see binary black holes at an average distance of 2 billion light years.

“We can’t ‘see’ black holes with telescopes. We made it. The team’s contributions to the Sept. 14 discovery include making predictions for anticipated detections, interpreting the astrophysics, analyzing the data and characterizing the detectors. Dark skies are still the windows to our knowledge of the greater Universe. Einstein and Gravitational Waves. We’re analyzing it.

ICOMOS–IAU Thematic Study on astronomical heritage. “We’ve been wandering around in the desert for 40 years looking for the promised land,” says Reitze of the search for gravitational waves. "&d="+screen.width+"x"+screen.height+"&auto=y&pid=wttuor",

", “He doesn’t normally call me ‘baby,’” Kalogera, who was dissertation adviser for Farr ’14 PhD, says with a laugh. A black hole’s gravity is so strong, not even light can escape it. I was working around the clock and I kept asking him to take care of the kids. Copyright © Reach 227,000 readers, including Northwestern undergraduate, graduate, and professional school alumni. The discovery confirmed a major prediction of Albert Einstein’s 1915 general theory of relativity (see “Einstein and Gravitational Waves”). It was predicted in the ’60s, they searched for it for a long time. "&jv="+navigator.javaEnabled()+"&c="+screen.colorDepth+"", Tell us what you think. And the media coverage of the discovery was tremendous. Starlight Initiative collaborates with the. Story Tools.

“When we get to our full design sensitivity, we should be seeing these kinds of events every few days.

“Ladies and gentlemen, we have detected gravitational waves,” announced exuberant Northwestern alumnus David Reitze ’83, LIGO executive director at the California Institute of Technology in Pasadena. But it would be five months before the LIGO astrophysicists let the rest of the world know about the greatest discovery in the modern age of astronomy, namely that through the detection of gravitational waves from two black holes that collided in a cataclysmic event 1.3 billion years ago, scientists now had a new way to probe the farthest reaches of the universe — perhaps all the way back to the Big Bang.

But the discovery depended on the work of scientists and engineers across many disciplines over many decades.

THE STAR BUSINESSWindow To The UniverseQuickly Megan Fellman, Erin Karter and Kristin Samuelson of the Department of University Relations contributed to this story. And they got it. On the morning of Feb. 11, LIGO and the National Science Foundation shared the stunning discovery with a large media contingent at the National Press Club in Washington, D.C., as tens of thousands watched over the Internet. “Then boom! (See an interview with Kalogera and Larson.). Independent Business Unfortunately current areas devoted to astronomical observation do not enjoy appropriate recognition.Ground-based observatories have historically provided the vast majority of our knowledge of outer space. Photo by Traci White. “We were on the front page of the New York Times, above the fold, so not just the Science section!” Kalogera, who was born in Greece, even received a congratulatory phone call from the country’s president and an invitation to meet with him the next time she’s in Athens. But for many months, I didn’t share what.

We didn’t want to make a statement until we were convinced that we were right.”. LIGO stopped running on Jan. 12. “It’s so cool that we can make devices that are capable of measuring these tiny, tiny effects that come from these massive cataclysmic collisions of black holes. Read more about the two awards.). We’re not putting an exclamation point on the theory. “At that point the cat was out of the bag,” says Reitze.

“They’re called blind injections. Starlight Foundation- Spain. “She sent me little tidbits all evening, then said, ‘Oh, we think there might be a signal.’ ”, “LIGO made a detection,” Kalogera finally emailed Larson hours later at midnight. Learn about ad rates, deadlines, and mechanical guidelines. A technician at work in the Livingston, La., observatory. This is the first Thematic Study in any field of science heritage. “Rai Weiss called it a monster — an amazing signal.” (Rainer Weiss, a professor of physics emeritus at MIT, invented the laser interferometric technique that is the basic operation of LIGO. By measuring the tiny disturbances gravitational waves make to space and time as they pass through the Earth, scientists observed ripples in the fabric of spacetime from the collision of two black holes in the distant universe. Laser physicist Dave Reitze ’83, executive director of the Laser Interferometer Gravitational-Wave Observatory at the California Institute of Technology in Pasadena. These exceptional sites, including their natural components, can be considered as “landscapes of science and knowledge”. The ability of the planet’s astronomical sites and observatories to detect and interpret data from outside the world we live in should be considered as a resource of extraordinary value for the progress of knowledge, as it has been throughout history.

The Windows to the Universe. But black holes do radiate gravitational waves, which are produced by accelerating masses. Until last September, a pair of black holes had only been studied in theory and on computers. Within days of the Sept. 14 event, an astrophysicist at Arizona State University twice tweeted that LIGO had detected gravitational waves. But “it’s very hard to hide these things from your partner when they’re in the same line of work,” Kalogera says. According to general relativity, a pair of black holes orbiting each other lose energy through the emission of gravitational waves, causing them to gradually approach each other over billions of years, and then much more quickly in the final minutes. They’re also making improvements to the sensitivity of the LIGO detectors. Within three minutes of the passing of the gravitational waves, LIGO computer algorithms flagged the detection as something very interesting — and an automated email alert was sent out to three people: two physicists, one at the University of Florida and one at the Massachusetts Institute of Technology, and a postdoc at the Albert Einstein Institute in Hanover, Germany, who just before noon noticed that LIGO had detected an event. The collaboration team had presented only half the set of data by the press conference, so the scientists are now analyzing the rest. ICOMOS–IAU Thematic Study on astronomical heritage. So that meant the 1,000-plus scientists in the LIGO collaboration had to keep the news a secret — from everyone outside the group (including other colleagues and researchers, and spouses, family members and friends).
