First Constraints on Source Counts at 350 Microns

Sophia A. Khan, Richard A. Shafer, Stephen Serjeant +16

We have imaged a 6 arcminute region in the Boötes Deep Field using the 350 m-optimised second generation Submillimeter High Angular Resolution Camera (SHARC II), achie…

On the discovery of the first 350 micron-selected galaxy

Sophia A. Khan, Richard A. Shafer, Dominic J. Benford +17

We report the detection of a 3.6sigma 350micron-selected source in the Bootes Deep Field. The source, the first Short-wavelength Submillimeter-selected Galaxy (SSG 1), was discover…

Resolving IRAS 09111-1007 at 350 microns - a different path to ULIRG formation?

Sophia A. Khan, Dominic J. Benford, David L. Clements +3

We have resolved the ultraluminous infrared galaxy (ULIRG), IRAS 09111-1007, with the new 350 micron-optimised Second Generation Submillimeter High Angular Resolution Camera (SHARC…

The X-ray Halo of GX 13+1

Randall K. Smith, Richard J. Edgar, Richard A. Shafer

We present observations of the X-ray halo around the LMXB GX 13+1 from the Chandra X-ray telescope. The halo is caused by scattering in interstellar dust grains, and we use it to d…

Calibrator Design for the COBE Far Infrared Absolute Spectrophotometer (FIRAS)

J. C. Mather, D. J. Fixsen, R. A. Shafer +2

The photometric errors of the external calibrator for the FIRAS instrument on the COBE are smaller than the measurement errors on the cosmic microwave background (CMBR) spectrum (t…
