SuperCam: a 64-pixel heterodyne imaging array for the 870-micron atmospheric window (Proceedings Paper)
Heterodyne imaging arrays submillimeter molecular spectroscopy
2014/12/23
We report on the development of SuperCam, a 64 pixel, superheterodyne camera designed for operation in the astrophysically important 870 μm atmospheric window. SuperCam will be used to answer fundamen...
Gaia: a Window to Large Scale Flows
Gaia Window Large Scale Flows redshifts galaxy distances
2012/2/21
Using redshifts as proxy for galaxy distances, estimates of the 2D transverse peculiar velocities of distant galaxies ($cz\ltsim 2\times 10^4 \kms$) can be obtained from Gaia's measurements of proper ...
The metallicity distribution of bulge clump giants in Baade's Window
Galaxy: bulge – Galaxy: formation – Galaxy: abundances – Stars: abundances – Stars: atmosphere
2011/10/20
We seek to constrain the formation of the Galactic bulge by means of analysing the detailed chemical composition of a large sample of red clump stars in Baade's window. We measure [Fe/H] in a sample o...
Deconvolution of window effect in galaxy power spectrum analysis
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We develop a new method for deconvolving the smearing effect of the survey window in the analysis of the galaxy multipole power spectra from a redshift survey. This method is based on the deconvolutio...
