System performance of a TDM test-bed with long flex harness towards the new X-IFU FPA-DM
D. Vaccaro, M. de Wit, J. van der Kuur +17
SRON (Netherlands Institute for Space Research) is developing the Focal Plane Assembly (FPA) for Athena X-IFU, whose Demonstration Model (DM) will use for the first time a time dom…
ATHENA X-IFU Demonstration Model: First joint operation of the main TES Array and its Cryogenic AntiCoincidence Detector (CryoAC)
M. D'Andrea, K. Ravensberg, A. Argan +28
The X-IFU is the cryogenic spectrometer onboard the future ATHENA X-ray observatory. It is based on a large array of TES microcalorimeters, which works in combination with a Cryoge…
Towards 100,000-pixel microcalorimeter arrays using multi-absorber transition-edge sensors
S. J. Smith, J. S. Adams, S. R. Bandler +15
We report on the development of multi-absorber transition edge sensors (TESs), referred to as hydras. A hydra consists of multiple x-ray absorbers each with a different thermal con…
Study of the dependency on magnetic field and bias voltage of an AC-biased TES microcalorimeter
Luciano Gottardi, James Adams, Catherine Bailey +15
At SRON we are studying the performance of a Goddard Space Flight Center single pixel TES microcalorimeter operated in an AC bias configuration. For x-ray photons at 6 keV the pixe…
The Atacama Cosmology Telescope: Cosmological parameters from three seasons of data
Jonathan L. Sievers, Renée A. Hlozek, Michael R. Nolta +90
We present constraints on cosmological and astrophysical parameters from high-resolution microwave background maps at 148 GHz and 218 GHz made by the Atacama Cosmology Telescope (A…
The Atacama Cosmology Telescope: Data Characterization and Map Making
Rolando Dünner, Matthew Hasselfield, Tobias A. Marriage +71
We present a description of the data reduction and mapmaking pipeline used for the 2008 observing season of the Atacama Cosmology Telescope (ACT). The data presented here at 148 GH…
The Atacama Cosmology Telescope: Cosmology from Galaxy Clusters Detected via the Sunyaev-Zel'dovich Effect
Neelima Sehgal, Hy Trac, Viviana Acquaviva +66
We present constraints on cosmological parameters based on a sample of Sunyaev-Zel'dovich-selected galaxy clusters detected in a millimeter-wave survey by the Atacama Cosmology Tel…
The Atacama Cosmology Telescope: Sunyaev Zel'dovich Selected Galaxy Clusters at 148 GHz in the 2008 Survey
T. A. Marriage, V. Acquaviva, P. A. R. Ade +68
We report on twenty-three clusters detected blindly as Sunyaev-Zel'dovich (SZ) decrements in a 148 GHz, 455 square-degree map of the southern sky made with data from the Atacama Co…
The Atacama Cosmology Telescope: Cosmological Parameters from the 2008 Power Spectra
J. Dunkley, R. Hlozek, J. Sievers +64
We present cosmological parameters derived from the angular power spectrum of the cosmic microwave background (CMB) radiation observed at 148 GHz and 218 GHz over 296 deg^2 with th…
The Atacama Cosmology Telescope: A Measurement of the Cosmic Microwave Background Power Spectrum at 148 and 218 GHz from the 2008 Southern Survey

We present measurements of the cosmic microwave background (CMB) power spectrum made by the Atacama Cosmology Telescope at 148 GHz and 218 GHz, as well as the cross-frequency spect…
The Atacama Cosmology Telescope: Calibration with WMAP Using Cross-Correlations
Amir Hajian, Viviana Acquaviva, Peter A. R. Ade +64
We present a new calibration method based on cross-correlations with WMAP and apply it to data from the Atacama Cosmology Telescope (ACT). ACT's observing strategy and map making p…
