• Physical Processes in the Interstellar Medium (2014, background): “This has an almost perfect black-body spectrum with a temperature TCMB = 2.725K (Fixsen & Mather, 2002).”
• ARCADE 2 MEASUREMENT OF THE ABSOLUTE SKY BRIGHTNESS AT 3–90 GHz (2009, methodology): “…(FIRAS) instrument across the peak of the CMB spectrum (∼60–∼600 GHz) limit deviations from a blackbody, with temperature 2.725±0.001 K, to be less than 50 parts per million (Fixsen & Mather 2002; Fixsen et al. 1996), but measurements at centimeter or longer wavelengths are less restrictive.”
• Fossil H ii regions: self-limiting star formation at high redshift (2003, background): “Thus, only ∼ 10−2 of the heat injected by UV photons is eventually utilized in setting the entropy floor; all energy expended in heating the gas above Tfloor is ’wasted’ (it is dumped into the CMB, where it may eventually be observable as a spectral distortion, Fixsen & Mather 2002).”
• CMB at 2 × 2 order: the dissipation of primordial acoustic waves and the observable part of the associated energy release (2012, background): “Two orders of magnitude improvement in sensitivity over COBE/FIRAS have in principle been possible for several years (Fixsen & Mather 2002), and the recently proposed CMB experiment PIXIE (Kogut et al. 2011) would be able to detect distortions at the level of∆Iν/Iν ≃ 10−8−10−7 in the frequency…”
• A computer program for fast non-LTE analysis of interstellar line spectra With diagnostic plots to interpret observed line intensity ratios (2007, methodology): “The main contribution is the cosmic microwave background (CMB) whose absolute temperature is taken to beTCBR = 2.725±0.001K based on the full COBE data set as analyzed by Fixsen & Mather (2002).”
• Diffuse Atomic and Molecular Clouds (2006, background): “For molecules with dipole moments (and hence, allowed rotational transitions), excitation can occur by stimulated absorption in the cosmic microwave background (CMB), and deexcitation can occur by spontaneous emission and by stimulated emission.”
• The evolution of CMB spectral distortions in the early Universe (2011, methodology): “(28) implies that for particles with lifetimes oftX ∼ 109s the limits from Cobe/Firas are f ∗X .”
