IR Properties of Galactic Cirrus Near The Polar Caps

We present a systematic study of the infrared properties of the high galactic latitude sky, by examining two large sections of the IRAS Sky Survey, which cover galactic latitudes from b=20 to b=90, and b=-20 to b=-90, at a reduced resolution of 7.5'/pixel. The IRAS Sky Survey Atlas (ISSA) plates are used to determine the variation in color R(12,25), R(25,60)and R(60,100) of clouds with spatial scales of 1-5 degrees, as a funtion of galactic latitude, and also a function of the brightness of the emitting material.

The Milky Way, the Local Group & the IR Tully-Fisher Diagram

Using the near infrared fluxes of local group galaxies derived from Cosmic Background Explorer/Diffuse Infrared Background Experiment band maps and published Cepheid distances, we construct Tully-Fisher diagrams for the Local Group.

(abstract) Spatial Power Spectral Measurements of IR Cirrus

We have used recently released IRAS Sky Survey Atlas (ISSA) image data to investigate the surface brightness distribution of selected regions of infrared cirrus using power spectral analysis techniques.
