Who got Nobel Prize in astrophysics?

The Nobel Prize in Physics was awarded to three astrophysicists Tuesday for work that was literally out of the world, and indeed the universe. They are Roger Penrose, an Englishman, Reinhard Genzel, a German, and Andrea Ghez, an American.

What did Andrea M Ghez discover?

S55Andrea M. Ghez / DiscoveredS55 is a star that is located very close to the centre of the Milky Way, near the radio source Sagittarius A*, orbiting it with an orbital period of 12.8 years. Wikipedia

When did Andrea Ghez discover the black hole?

It wasn’t until 2000 that Andrea Ghez and Reinhard Genzel separately mapped the orbits of stars hurtling around the black hole. These orbits showed that the hidden object’s mass was so huge and its size so small that there was nothing else it could be.

What did Andrea Ghez study?

Ghez began her career in astronomy studying young binary stars using the technique of infrared speckle imaging, which removes the blurring Earth’s atmosphere imposes on astronomical images by taking many pictures with very short exposure times and adding them together.

Who is Reinhard Genzel and Andrea Ghez?

Since the 1990s, Reinhard Genzel and Andrea Ghez with their respective research teams, have developed and refined techniques for studying the movement of stars. Observations of stars in the area around Sagittarius A* in the middle of our galaxy, the Milky Way, revealed a super massive black hole.

Who is Andrea Ghez?

Andrea Ghez is a stargazing detective, tracking the visible and invisible forces lurking in the vastness of interstellar space. Seeing the unseen (from 26,000 light-years away) is a specialty of UCLA astronomer Andrea Ghez.

What did Penrose and Genzel and Ghez discover?

The Nobel Committee cites Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity”, and Genzel and Ghez “for the discovery of a supermassive compact object at the centre of our galaxy”.

What did Elizabeth Ghez do for Science?

Ghez received a MacArthur “genius grant” in 2008 for her work in surmounting the limitations of earthbound telescopes. Early in her career, she developed a technique known as speckle imaging, which combined many short exposures from a telescope into one much-crisper image.
