Interview with Sheng Yang

I’m from a small town named Honghu, which is located in the central part of China. In Chinese, ‘hu' means lake, so my hometown is famous because of a beautiful lake and is named after it. I did my masters degree at the Beijing Normal University, and my PhD at the University of Padova, including a year and a half at UC Davis. After that, I did a one year postdoc at the Observatory of Padova, INAF, and then I moved to Stockholm.

Extreme-Gravity Stars

The lives of massive stars are characterized by companionship: these stars are almost always found in gravitationally bound pairs. As such massive binaries evolve further, their cores run out of nuclear fuel and the stars can explode as supernovae, leaving behind in their centers either a neutron star or a black hole. In most cases such an explosion would be fatal for the binary, and disrupt it. In some cases, however, the final phases of binary stellar evolution can produce two compact objects -either white dwarfs, neutron stars or black … Continue Reading ››

Gravitational waves finally detected

It seems that nearly exactly 100 years after their prediction by Albert Einstein, Gravitational Waves have finally been directly detected for the first time. Speakers of the LIGO experiment announced yesterday that they have witnessed the final stages of the inspiral and merger of a massive black hole binary system. This marks the beginning of a new type of astronomy with gravitational waves that allows to explore a so-far completely unknown side of the Universe.
