DIRBE Minus 2MASS: the Cosmic Infrared Background at 3.5 Microns | | Edward L. Wright

11 Jul 2001 | | Subject: | astro-ph | | Affiliation: | UCLA | | Abstract: | Stellar fluxes from the 2MASS catalog are used to remove the contribution due to Galactic stars from the intensity measured by DIRBE in 13 regions in the North and South Galactic polar caps. Allowing for a constant calibration factor between the DIRBE 3.5 micron intensity and the 2MASS 2.2 micron fluxes gives very small pixel to pixel scatter. After subtracting the interplanetary and Galactic foregrounds, a residual intensity of 16.1 +/- 4 kJy/sr or 13.8 +/- 3.4 nW/m^2/sr at 3.5 microns is found. A similar analysis at 2.2 microns gives a residual intensity of 17.6 +/- 4.4 kJy/sr or 24 +/- 6 nW/m^2/sr. The intercepts of the DIRBE minus 2MASS correlation at 1.25 microns show more scatter and are a much smaller fraction of the foreground, leading to a weak limit on the CIRB of 10.1 +/- 7.4 kJy/sr or 24.3 +/- 18 nW/m^2/sr (1 sigma). | | Source: | arXiv, astro-ph/0107205 | | Services: | Forum | Review | PDF | Favorites | |
