Molecular gas and dust in the highly magnified z = 2.8 galaxy behind the Bullet Cluster
Daniel Johansson, Cathy Horellou, Omar Lopez-Cruz +8
The gravitational magnification provided by massive galaxy clusters makes it possible to probe the physical conditions in distant galaxies that are of lower luminosity than those i…
A LABOCA survey of submillimeter galaxies behind galaxy clusters
Daniel Johansson, Haukur Sigurdarson, Cathy Horellou
Context: Submillimeter galaxies are a population of dusty star-forming galaxies at high redshift. Measuring their properties will help relate them to other types of galaxies, both…
Submillimeter galaxies behind the Bullet Cluster (1E 0657-56)
Daniel Johansson, Cathy Horellou, Martin W. Sommer +6
Clusters of galaxies are effective gravitational lenses able to magnify background galaxies and making it possible to probe the fainter part of the galaxy population. Submillimeter…
Non-parametric modeling of the intra-cluster gas using APEX-SZ bolometer imaging data
K. Basu, Y. -Y. Zhang, M. W. Sommer +23
We demonstrate the usability of mm-wavelength imaging data obtained from the APEX-SZ bolometer array to derive the radial temperature profile of the hot intra-cluster gas out to ra…
Constraints on the High-l Power Spectrum of Millimeter-wave Anisotropies from APEX-SZ
C. L. Reichardt, O. Zahn, P. A. R. Ade +27
We present measurements of the angular power spectrum of millimeter wave anisotropies with the APEX-SZ instrument. APEX-SZ has mapped 0.8 square degrees of sky at a frequency of 15…
Multi-frequency imaging of the galaxy cluster Abell 2163 using the Sunyaev-Zel'dovich Effect
M. Nord, K. Basu, F. Pacaud +30
We used the APEX-SZ and LABOCA bolometer cameras on the APEX telescope to map the decrement of the Sunyaev-Zeldovich effect at 150 GHz and the increment at 345 GHz toward the galax…
