CXC-sponsored annual summer workshops focus on X-ray-related science topics.

Workshop size (80-120) and length (~2.5 days) engages most aspects of the topic, advances collaborations.

Topic choice based on proposal pressure, relevance, clamor.

2012 X-Ray Binaries Workshop Abstract

In 1962, Scorpius X-1 became the first X-ray source discovered outside the Solar System. In the 50 years since, X-ray binaries have proven to be important for studies of fundamental physical processes such as mass accretion and jet formation. Contemporary X-ray satellites provide detailed spectroscopic studies of individual Galactic black hole and neutron star binaries, as well as population studies of low-mass X-ray binaries in globular clusters, high-mass X-ray binaries and ultra-luminous X-ray sources in starburst galaxies. This meeting will celebrate the startling discovery of Scorpius X-1, highlight the latest results in our understanding of the formation of black holes, neutron stars and X-ray binaries, as well as the use of X-ray binaries for testing the laws of physics in the extreme environment close to black holes and neutron stars.

1962: The Discovery of Extra-Solar X-The Discovery of Extra-Solar X-raysrays

From TIME magazine (01 Nov, 1963):

Professor Philip Morrison of Cornell thinks the X rays may be generated

when starlight picks up energy from high-speed electrons far out in

space. Professor Minoru Oda of M.I.T. figures that the X rays come from

a magnetic field surrounding the edges of the galactic nucleus. British

Cosmologist Fred Hoyle suspects that they may be connected with the

creation of new matter in the vast emptiness between the galaxies....

It may be that charged particles blown out of the sun knock

soft X rays out of the moon, and if this were proved it would give vital

information about the lunar surface, where astronauts may some day land.

"There are things going on in space," says Dr. Rossi, "that are still

unknown. That is what so excites us. We hope that by means of X rays we

can detect some of these phenomena."
