Transverse Velocities with the Moving Lens Effect
Selim C. Hotinli, Joel Meyers, Neal Dalal +6
Gravitational potentials which change in time induce fluctuations in the observed cosmic microwave background (CMB) temperature. Cosmological structure moving transverse to our lin…
Dipole Distortions in the Intergalactic Medium
Derek Inman, Ue-Li Pen, Francisco Villaescusa-Navarro
Baryonic feedback can significantly modify the spatial distribution of matter on small scales and create a bulk relative velocity between the dominant cold dark matter and the hot…
Core Cosmology Library: Precision Cosmological Predictions for LSST
Nora Elisa Chisari, David Alonso, Elisabeth Krause +27
The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of valid…
Cluster Cosmology Constraints from the 2500 deg SPT-SZ Survey: Inclusion of Weak Gravitational Lensing Data from Magellan and the Hubble Space Telescope
S. Bocquet, J. P. Dietrich, T. Schrabback +77
We derive cosmological constraints using a galaxy cluster sample selected from the 2500~deg SPT-SZ survey. The sample spans the redshift range and contains 343 c…
The Cross-correlation of KSZ Effect and 21 cm Intensity Mapping with Tidal Reconstruction
Dongzi Li, Hong-Ming Zhu, Ue-Li Pen
We discuss the possibility of studying diffuse baryon distributions with kinematic Sunyaev-Zel'dovich (kSZ) effect by correlating cosmic microwave background (CMB) temperature fluc…
Measurement of the Splashback Feature around SZ-selected Galaxy Clusters with DES, SPT and ACT
T. Shin, S. Adhikari, E. J. Baxter +107
We present a detection of the splashback feature around galaxy clusters selected using their Sunyaev-Zel'dovich (SZ) signal. Recent measurements of the splashback feature around op…
