Astronomers detect evidence of time when universe emerged from "Dark Ages"

Astronomers at the California Institute of Technology announced today the discovery of the long-sought "Cosmic Renaissance," the epoch when young galaxies and quasars in the early universe first broke out of the "Dark Ages" that followed the Big Bang.

"It is very exciting," said Caltech astronomy professor S. George Djorgovski, who led the team that made the discovery. "This was one of the key stages in the history of the universe."

Brightest Quasars Inhabit Galaxies withStar-Forming Gas Clouds, Scientists Discover

A team of scientists at the California Institute of Technology and the State University of New York at Stony Brook has found strong evidence that high-luminosity quasar activity in galaxy nuclei is linked to the presence of abundant interstellar gas and high rates of star formation.

In a presentation at the summer meeting of the American Astronomical Society, Caltech astronomy professor Nick Scoville and his colleagues reported today that the most luminous nearby optical quasar galaxies have massive reservoirs of interstellar gas much like the so-called ultraluminous infrared galaxies (or UL

New Analysis of BOOMERANG Data Uncovers Harmonics of Early Universe

Cosmologists from the California Institute of Technology and their international collaborators have discovered the presence of acoustic "notes" in the sound waves that rippled through the early universe.

The existence of these harmonic peaks, discovered in an analysis of images from the BOOMERANG experiment, further strengthens results last year showing that the universe is flat. Also, the new results bolster the theory of "inflation," which states that the universe grew from a tiny subatomic region during a period of violent expansion a split second after the Big Bang.

Distant Massive Explosion Reveals a Hidden Stellar Factory

A gamma-ray burst detected in February has led astronomers to a galaxy where the equivalent of 500 new suns is being formed each year.

The discovery of a new "starburst galaxy," made by researchers from the National Radio Astronomy Observatory and the California Institute of Technology, provides support for the theory that gamma-ray bursts are caused by exploding young massive stars. Details of the discovery are being presented today at the Gamma 2001 conference.

Caltech Physicist Awarded Sakurai Prize

PASADENA, Ca-Particle physicists immerse themselves in a subatomic world. They deal with the quirkiest bits of matter-quarks, leptons, gauge bosons and the like-particles infinitesimally small, often unstable and short-lived, and sometimes so elusive they can't be seen at all, but are only theorized to exist. For his work in this area, the American Physical Society has awarded the California Institute of Technology's Mark Wise the J.J. Sakurai Prize for Theoretical Particle Physics.

Caltech Professor Receives American Astronomical Society's Highest Honor

The American Astronomical Society (AAS) has awarded Wallace L. W. Sargent, the Ira S. Bowen Professor of Astronomy at the California Institute of Technology and former director of Palomar Observatory, with the AAS's highest honor, the Henry Norris Russell Lectureship. This honor, which is given annually by the AAS, recognizes "a lifetime of eminence in astronomical research."

Professor Elected to Greek Academy

Tom M. Apostol, professor of mathematics emeritus and the creator and project director of Project MATHEMATICS! at the California Institute of Technology, has been elected a corresponding member of the Academy of Athens.

Caltech Receives Funding to Establish Network of Cosmic-Ray Detectors in High Schools

Los Angeles-area high school students will team up with California Institute of Technology researchers to study ultrahigh-energy cosmic rays on their own campuses, thanks to a recent grant from the Weingart Foundation.

Caltech Receives $10 Million Grant fromSherman Fairchild Foundation

The California Institute of Technology has received a $10 million grant from the Sherman Fairchild Foundation to establish an endowment for the existing Sherman Fairchild Postdoctoral Scholars Program in theoretical physics, theoretical astrophysics, and mathematics.

Caltech Faculty Member Receives Packard Fellowship

Pasadena—Rahul Pandharipande, associate professor of mathematics at the California Institute of Technology, has been awarded a $625,000 Packard Fellowship for his work in advanced mathematics and the study of the geometry of algebraic curves.

Every year the foundation selects 24 Fellows to receive these awards, which are distributed over five years.
