We use the angular power spectrum of the cosmic microwave background, measured during the North American test flight of the Boomerang experiment, to constrain the geometry of the universe. Within the class of cold dark matter models, we find that the overall fractional energy density of the universe Omega is constrained to be 0.85</=Omega</=1.25 at the 68% confidence level. Combined with the COBE measurement, the data on degree scales from the Microwave Anisotropy Telescope in Chile, and the… 
Measurement of a Peak in the Cosmic Microwave Background Power Spectrum from the North American Test Flight of Boomerang.
We describe a measurement of the angular power spectrum of anisotropies in the cosmic microwave background (CMB) at scales of 0&fdg;3 to 5 degrees from the North American test flight of the Boomerang
Constraints on Cosmological Parameters from MAXIMA-1
We set new constraints on a seven-dimensional space of cosmological parameters within the class of inflationary adiabatic models. We use the angular power spectrum of the cosmic microwave background
Constraining the shape of the CMB: A peak-by-peak analysis
The recent measurements of the power spectrum of Cosmic Microwave Background anisotropies are consistent with the simplest inflationary scenario and big bang nucleosynthesis constraints. However,
Observations and Theory of The Cosmic Microwave Background
An intuitive introduction to the theory behind Cosmic Microwave Background (CMB) anisotropies is given, including the form of power spectrum expected in standard cosmological models.This is followed
COBE constraints on a compact toroidal low-density universe
In this paper, the cosmic microwave background (CMB) anisotropy in a multiply connected compact flat 3-torus model with the cosmological constant is investigated. Using the COBE-DMR four-year data, a
Observations of The Cosmic Microwave Background
This contribution aims to provide a brief introduction to the observational side of Cosmic Microwave Background (CMB) astronomy. Experimental techniques and contaminants are discussed, and then some
Observations of the cosmic microwave background and CMB interferometers
The Cosmic Microwave Background (CMB) provides us with a window on the early universe through which we are starting to see a great deal of detail. The recent BOOMERANG and MAXIMA results have given
Density of cold dark matter
The nature of dark matter is increasingly constrained by cosmological data. In this paper, we examine the implications of the Cosmic Microwave Background anisotropy limits on the density of cold dark


A Measurement of the Angular Power Spectrum of the Microwave Background Made from the High Chilean Andes
We report on a measurement of the angular spectrum of the anisotropy of the microwave sky at 30 and 40 GHz between and . The data, covering roughly 600 deg 2 , support a rise in the angular spectrum
The Gravitational Wave Contribution to the Cosmic Microwave Background Anisotropies
We study the possible contribution of a stochastic gravitational wave background to the anisotropy of the cosmic microwave background (CMB) in cold and mixed dark matter models. We test this
Power Spectra of the Cosmic Microwave Background and Density Fluctuations Seeded by Local Cosmic Strings
We compute the power spectra in the cosmic microwave background and cold dark matter (CDM) fluctuations seeded by strings, using the largest string simulations performed so far. We find that local

Measuring cosmological parameters with cosmic microwave background experiments.
The degree to which factors related to primordial energy density and gravitational wave fluctuations can be separately resolved from combined small- and large-angular-scale anisotropy observations is examined.
Why not consider closed universes
We consider structure formation and CMB anisotropies in a closed universe, both with and without a cosmological constant. The CMB angular power spectrum and the matter transfer function are
