TL;DR: In this paper, the authors presented a catalog of 68 galaxy clusters, of which 19 are new discoveries, detected via the Sunyaev-Zel'dovich effect (SZ) at 148 GHz in the Atacama Cosmology Telescope (ACT) survey of 504 square degrees on the celestial equator.

TL;DR: The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission to measure the gravity-wave signature of primordial inflation through its distinctive imprint on the linear polarization of the cosmic microwave background.

TL;DR: In this paper, a model of primary cosmological and secondary foreground parameters is fit to the map power spectra and lensing deflection power spectrum, including contributions from both the thermal Sunyaev-Zeldovich (tSZ) effect and the kinematic SZ effect, Poisson and correlated anisotropy from unresolved infrared sources, radio sources and the correlation between the tSZ effect and infrared sources.

Seven-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Are There Cosmic Microwave Background Anomalies?

TL;DR: In this article, the authors examine potential anomalies and present analyses and assessments of their significance and conclude that there is no compelling evidence for deviations from the LCDM model, which is generally an acceptable statistical fit to WMAP and other cosmological data.
Journal ArticleDOI
The nature of a gravitationally lensed sub-millimetre arc in MS0451.6-0305: two interacting galaxies at z~2.9?
Colin Borys,Scott Chapman,Megan Donahue,G. G. Fahlman,Mark Halpern,Jean-Paul Kneib,Peter Newbury,Douglas Scott,Graham P. Smith +8 more
TL;DR: In this article, the authors presented a new SCUBA image of the cluster MS0451, which exhibits strong, extended sub-mm flux at 850 microns, coincident with a previously known optical arc (which turns out to be a strongly lensed Lyman Break Galaxy at z=2.911), as well as with a newly identified multiply-imaged ERO (Extremely Red Object) pair predicted to be at a similar, if not identical redshift.
