Jeremiah Ostriker, who was extending dark powers that form the universe, dies in 86

Jeremiah Ostriker, an astronomical physicist who helped a revolution in the human viewpoint of the universe, died, and revealed that it is a darker and darker world than those that we can see, and which are governed by invisible forms of the issue and energy that we still do not understand, on Sunday at his home in the upper western side of Manhattan. It was 87.

His daughter Rebecca Ostrachr said the cause is kidney disease at the end of the stage.

For more than four decades, most of them at Princeton University, Dr. Ostiker’s work is our understanding of how to form galaxies and develop while exploring the nature of the vibrant stars, the role of black holes in the development of the universe and what the universe is made of it.

Before the 1970s, most astronomers believed that galaxies were mostly stars.

“Ostrarch was the most important person in persuading the astronomical society that this natural and tempting assumption Simonz FoundationWhich supports scientific research, written in 2022, nominating Dr. Ostekker, his teacher, for the Cravors Award, the astronomical equivalent of Nobeel. He pointed out, “The eloquent call to Dr. Ostroker for the new model at the time, which was not in the galaxies, was not a small contaminated in the center of Hala much larger than the dark material than the unknown formation.”

He said that Dr. Ostroker’s work was “the most wonderful review in our understanding of galaxies” in half a century.

Jerry Ostroker, as he was known to friends and colleagues, was a man with a thorny feeling of humor and a soft but leader, ready to go anywhere in which he led the scientific data and calculations, and was not shy of questioning the assumptions – or enjoyment. He was prominently displayed in his home, a young image of himself, taken in Cambridge, Massachusetts, driving a scooter of cars while his wife, Alisia Austker, was sitting behind him, raising a bottle of wine on her lips. (A close look shows the cork is still in the bottle.)
