We present a map and an angular power spectrum of the anisotropy of the cosmic microwave background (CMB) from the first flight of the Millimeter-wave Anisotropy Experiment Imaging Array (MAXIMA). MAXIMA is a balloon-borne experiment with an array of 16 bolometric photometers operated at 100 mK. MAXIMA observed a 124 deg2 region of the sky with 10' resolution at frequencies of 150, 240, and 410 GHz. The data were calibrated using in-flight measurements of the CMB dipole anisotropy. A map of the CMB anisotropy was produced from three 150 and one 240 GHz photometer without need for foreground subtractions. Analysis of this CMB map yields a power spectrum for the CMB anisotropy over the range 36 ≤ l ≤ 785. The spectrum shows a peak with an amplitude of 78 ± 6 μK at l ≃ 220 and an amplitude varying between ~40 and ~50 μK for 400 ≲ l ≲ 785.

Myths and truths concerning estimation of power spectra: the case for a hybrid estimator (2003, methodology): “The NRML estimator has been used widely in the analysis of CMB experiments, for example, MAXIMA1 (Hanany et al., 2000), BOOMERANG (de Bernardis et al., 2000), WMAP (Hinshaw et al., 2003) and to galaxy clustering (Efstathiou and Moody 2001).”
Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological implications from two decades of spectroscopic surveys at the Apache Point Observatory (2020, result): “Developmental milestones for the current standard model of these properties, the spatially-flat ΛCDM model, include measurements of the expansion history using Type Ia supernovae (SNe Ia) in the 1990’s, which provided the first evidence for cosmic acceleration (Riess et al. 1998; Perlmutter et al. 1”

THE ATACAMA COSMOLOGY TELESCOPE: COSMOLOGICAL PARAMETERS FROM THE 2008 POWER SPECTRUM (2010, methodology): “Measurements of anisotropies in the cosmic microwave background (CMB) have played a central role in the development of the current concordance cosmological model (e.g., Smoot et al. 1992; Miller et al. 1999; de Bernardis et al. 2000; Hanany et al. 2000; Spergel et al. 2003).”
Towards a free–free template for CMB foregrounds (2003, background): “…are sensitive enough to measure the primordial fluctuations which have an amplitude in the range of ≈ 20−100 µK over the ℓ-range 10−2000 which corresponds to angular scales of ≈ 10◦ − 10 arcmin (Hanany et al. 2000; Mauskopf et al. 2000; Padin et al. 2001; Halverson et al. 2002; Scott et al. 2002).”
Measuring Ωm with the ROSAT Deep Cluster Survey (2001, unknown): “Unless otherwise specified, in the following we assume flat spatial geometry provided by a cosmological constant term, ΩΛ = 1 − Ωm, consistent with recent small scale measurements of CMB anisotropies (de Bernardis et al. 2000; Hanany et al. 2000).”
