Cross-correlation of gravitational lensing from DES Science Verification data with SPT and Planck lensing
D. Kirk, Y. Omori, A. Benoit-Lévy +89
We measure the cross-correlation between weak lensing of galaxy images and of the cosmic microwave background (CMB). The effects of gravitational lensing on different sources will…
Atomic beings and the discovery of gravity
George De Conto, Guilherme Franzmann
We aim to bring a new perspective about some aspects of the current research in Cosmology. We start with a brief introduction about the main developments of the field in the last c…
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…
Simulations of the Pairwise Kinematic Sunyaev-Zel'dovich Signal
Samuel Flender, Lindsey Bleem, Hal Finkel +3
The pairwise kinematic Sunyaev-Zel'dovich (kSZ) signal from galaxy clusters is a probe of their line-of-sight momenta, and thus a potentially valuable source of cosmological inform…
Cosmic Microwave Background Spectral Distortions from Cosmic String Loops
Madeleine Anthonisen, Robert Brandenberger, Alex Laguë +2
Cosmic string loops contain cusps which decay by emitting bursts of particles. A significant fraction of the released energy is in the form of photons. These photons are injected n…
Planck 2015 results. XII. Full Focal Plane simulations
Planck Collaboration, P. A. R. Ade, N. Aghanim +228
We present the 8th Full Focal Plane simulation set (FFP8), deployed in support of the Planck 2015 results. FFP8 consists of 10 fiducial mission realizations reduced to 18144 maps,…
