The second flight of the Medium Scale Anisotropy Measurement (MSAM194) observed the same field as the first flight (MSAM1-92) to confirm our earlier measurement of cosmic microwave background radiation (CMBR) anisotropy. This instrument chops a 30 beam in a 3 position pattern with a throw of ±40′, and simultaneously measures single and double differenced sky signals. We observe in four spectral...

The goal of the second flight of the Medium Scale Anisotropy Measurement (MSAM1-94) was to confirm the measurement of cosmic microwave background radiation (CMBR) anisotropy made in the first flight (MSAM1-92). The CMBR anisotropy and interstellar dust emission signals from the two flights are compared by forming the sum and difference of those portions of the data with the same pointings on th...

Observations from the first flight of the Medium Scale Anisotropy Measurement (MSAM1-92) are analyzed to search for the Sunyaev-Zel’dovich (SZ) effect towards the Coma cluster. This balloon-borne instrument uses a 28 FWHM beam and a three position chopping pattern with a throw of ±40. With spectral channels at 5.7, 9.3, 16.5, and 22.6 cm, the observations simultaneously sample the frequency ran...

In our search for “hidden” AGN we present results from a Chandra observation of the nearby cluster Abell 2255. Eight cluster galaxies are associated with point-like X-ray emission, and we classify these galaxies based on their X-ray, radio, and optical properties. At least three are associated with active galactic nuclei (AGN) with no optical signatures of nuclear activity, with a further two b...

We have developed a linearly polarized Ytterbiumdoped fiber ring laser with a single longitudinal mode output at 1064 run. A fiber-coupled intracavity phase modulator ensured mode-hop free operation and allowed fast frequency tuning. The fiber laser was locked with high stability to an iodine-stabilized laser, showing a frequency nOIse suppressIOn of a factor,...., 10 at 1 ':IlHz 50"", DET Conf...
