Combining galaxy and 21cm surveys
J. D. Cohn, Martin White, Tzu-Ching Chang +3
Acoustic waves traveling through the early Universe imprint a characteristic scale in the clustering of galaxies, QSOs and inter-galactic gas. This scale can be used as a standard…
Probing star formation in the dense environments of z~1 lensing halos aligned with dusty star-forming galaxies detected with the South Pole Telescope
N. Welikala, M. Béthermin, D. Guery +46
We probe star formation in the environments of massive dark matter halos at redshifts of . This star formation is linked to a sub-millimetre cl…
A cryogenic rotation stage with a large clear aperture for the half-wave plates in the Spider instrument
Sean Bryan, Peter Ade, Mandana Amiri +47
We describe the cryogenic half-wave plate rotation mechanisms built for and used in Spider, a polarization-sensitive balloon-borne telescope array that observed the Cosmic Microwav…
Interloper bias in future large-scale structure surveys
Anthony R. Pullen, Christopher M. Hirata, Olivier Dore +1
Next-generation spectroscopic surveys will map the large-scale structure of the observable universe, using emission line galaxies as tracers. While each survey will map the sky wit…
Planck 2015 results. XXV. Diffuse low-frequency Galactic foregrounds
Planck Collaboration, P. A. R. Ade, N. Aghanim +238
(abridged) We discuss the Galactic foreground emission between 20 and 100GHz based on observations by Planck/WMAP. The Commander component-separation tool has been used to separate…
Planck 2015 results. V. LFI calibration
Planck Collaboration, P. A. R. Ade, N. Aghanim +206
We present a description of the pipeline used to calibrate the Planck Low Frequency Instrument (LFI) timelines into thermodynamic temperatures for the Planck 2015 data release, cov…
