Black Hole That Periodically Ejects Its Inner Disk As Jets Discovered

Astronomers observing a disk of matter spiralling into a black hole in our galaxy have discovered that the black hole periodically hurls the inner portion of the disk into space as jets travelling at near the speed of light.

Caltech Astrophysicist Charles Steidel Receives $500,000 Packard Foundation Fellowship

A Caltech astrophysicist who searches for the oldest and most distant structures in the universe has been named a recipient of a $500,000 grant from the David and Lucile Packard Foundation. Caltech Astrophysicist Charles Steidel Receives $500,000 Packard Foundation Fellowship October 1997 97

Astronomers Detect Relativistically Expanding Clouds Around the May 8 Gamma-Ray Burst

Astrophysicists still don't know what caused the gamma-ray burst of May 8, but they now have a size and rate of expansion for its remnant "fireball" to add to the location and distance.

Possible Planet-Forming Disk imaged by Caltech Radio Astronomers

A giant disk of gas and dust over 10 times the size of our own solar system has been detected rotating around a young star in the constellation of Auriga. Possible Planet-Forming Disk imaged by Caltech Radio Astronomers August 1997 97

Caltech Astronomers Crack the Puzzle of Cosmic Gamma-Ray Bursts

A team of Caltech astronomers has pinpointed a gamma-ray burst several billion light-years away from the Milky Way. The team was following up on a discovery made by the Italian/Dutch satellite BeppoSAX.

Caltech Astronomer Obtains Data That Could Resolve the "Age Problem"

Dr. Neill Reid, using information collected by the European Space Agency's Hipparcos satellite, has determined that a key distance measure used to compute the age of certain Milky Way stars is off by 10 to 15 percent. The new data leads to the conclusion that the oldest stars are actually 11 to 13 billion years old, rather than 16 to 18 billion years old, as had been thought.

Renowned Physicist Robert B. Leighton Dies

PASADENA—Robert B. Leighton, a longtime physicist and astronomer at the California Institute of Technology, died Sunday, March 9, 1997, after a long illness. He was 77.

Caltech Astronomers Obtain the Most Detailed Infared Image of the Environment of an Active Black Hole

TORONTO — Sophisticated imaging techniques applied on the Keck Telescope have uncovered a new structure in a nearby active galaxy.

The image and associated research are being presented today at the semiannual meeting of the American Astronomical Society. Alycia Weinberger, a doctoral student in physics at the California Institute of Technology, and her collaborators have used the computer-intensive technique of speckle imaging and the 10-meter W. M. Keck Telescope atop Mauna Kea, Hawaii, to image the nucleus of NGC 1068.

Fairchild Foundation Awards $2.5 Million to Caltech Physics and Astronomy

PASADENA—The Sherman Fairchild Foundation has awarded $2.5 million to the California Institute of Technology to support postdoctoral researchers in physics and astronomy.

The gift, which extends over eight years, will support six scientists in theoretical physics or astrophysics, five in observational optical-infrared astronomy, and two in experimental physics, astrophysics, or radio astronomy. The first contingent of Sherman Fairchild Scholars will begin their term at Caltech in the fall of 1996.
