Leuschner Observatory report.

An Infrared Camera for Leuschner Observatory and the Berkeley Undergraduate Astronomy Lab

We describe the design, fabrication, and operation of an infrared camera which is in use at the 30-inch telescope of the Leuschner Observatory. The camera is based on a Rockwell PICNIC 256×256 pixel HgCdTe array, which is sensitive from 0.9-2.5 μm. The primary purpose of this telescope is for undergraduate instruction. The cost of the camera has been minimized by using commercial parts whereeve...

Pierre Auger Observatory: Status Report

The Pierre Auger Observatory is a large international effort to provide measurements of extensive air showers (EAS) initiated in the upper atmosphere by cosmic rays with energies above 10 eV , the Ultra High Energy Cosmic Rays (UHECR’s). The explanations for the origin, acceleration processes and composition of the UHECR’s face theoretical and experimental difficulties, due to the extremely low...

The Chandra X-Ray Observatory: Progress Report and Highlights

Over the past 13 years, the Chandra X-ray Observatory’s ability to provide high resolution X-ray images and spectra have established it as one of the most versatile and powerful tools for astrophysical research in the 21 century. Chandra explores the hot, high-energy regions of the universe, observing X-ray sources with fluxes spanning more than 10 orders of magnitude, from the X-ray brightest,...

Annual Report of the National Astronomical Observatory of Japan

Most distant and ancient supernovae discovered by the Subaru Telescope. In the image, which show the Subaru Deep Field, numerous supernovae related to white dwarfs were found, and ten of them had exploded more than ten billion years ago. This discovery gives an important clue to study how the heavy elements created in the ancient universe (Graur et al.
