KiDS+VIKING-450: Cosmic shear tomography with optical+infrared data
H. Hildebrandt, F. Köhlinger, J. L. van den Busch +25
We present a tomographic cosmic shear analysis of the Kilo-Degree Survey (KiDS) combined with the VISTA Kilo-Degree Infrared Galaxy Survey (VIKING). This is the first time that a f…
Baryon acoustic oscillation methods for generic curvature: Application to the SDSS-III Baryon Oscillation Spectroscopic Survey
Asta Heinesen, Chris Blake, Yong-Zhuang Li +1
We develop methods for investigating baryon acoustic oscillation (BAO) features in cosmological models with non-trivial (but slowly varying) averaged spatial curvature: models that…
The environmental dependence of the baryon acoustic peak in the Baryon Oscillation Spectroscopic Survey CMASS sample
Chris Blake, Ixandra Achitouv, Angela Burden +1
The environmental dependence of galaxy clustering encodes information about the physical processes governing the growth of cosmic structure. We analyze the baryon acoustic peak as…
The first sample of spectroscopically confirmed ultra-compact massive galaxies in the Kilo Degree Survey
C. Tortora, N. R. Napolitano, M. Spavone +25
We present results from an ongoing investigation using the Kilo Degree Survey (KiDS) on the VLT Survey Telescope (VST) to provide a census of ultra-compact massive galaxies (UCMGs)…
Intensity mapping cross-correlations II: HI halo models including shot noise
L. Wolz, S. G. Murray, C. Blake +1
HI intensity mapping data traces the large-scale structure matter distribution using the integrated emission of neutral hydrogen gas (HI). The cross-correlation of the intensity ma…
Low Redshift Baryon Acoustic Oscillation Measurement from the Reconstructed 6-degree Field Galaxy Survey
Paul Carter, Florian Beutler, Will J. Percival +3
Low redshift measurements of Baryon Acoustic Oscillations (BAO) test the late time evolution of the Universe and are a vital probe of Dark Energy. Over the past decade both the 6-d…
