Evidence of a truncated spectrum in the angular correlation function of the cosmic microwave background
Fulvio Melia, Martin Lopez-Corredoira
The lack of large-angle correlations in the fluctuations of the cosmic microwave background (CMB) conflicts with predictions of slow-roll inflation. But though probabilities (< 0.2…
Relative contribution of the hydrogen 2S two-photon decay and Lyman-alpha escape channels during the epoch of cosmological recombination
J. A. Rubino-Martin, R. A. Sunyaev
We discuss the evolution of the ratio in number of recombinations due to 2s two photon escape and due to the escape of Lyman- photons from the resonance during the epoch of cosm…
The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
Andrew Robertson, Richard Massey, Vincent Eke +10
We present the first simulated galaxy clusters (M_200 > 10^14 Msun) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater diversity in both dar…
Extracting cosmological information from the angular power spectrum of the 2MASS Photometric Redshift catalogue
A. Balaguera-Antolínez, M. Bilicki, E. Branchini +1
Using the almost all-sky 2MASS Photometric Redshift catalogue (2MPZ) we perform for the first time a tomographic analysis of galaxy angular clustering in the local Universe ($z<0.2…
Growing a `Cosmic Beast': Observations and Simulations of MACS J0717.5+3745
M. Jauzac, D. Eckert, M. Schaller +18
We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS\,J0717.5+3745 (\,$10^{15}…
Intracluster Light at the Frontier II: The Frontier Fields Clusters
Mireia Montes, Ignacio Trujillo
Multiwavelength deep observations are a key tool to understand the origin of the diffuse light in clusters of galaxies: the intra-cluster light (ICL). For this reason, we take adva…
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: a tomographic analysis of structure growth and expansion rate from anisotropic galaxy clustering
Yuting Wang, Gong-Bo Zhao, Chia-Hsun Chuang +4
We perform a tomographic analysis of structure growth and expansion rate from the anisotropic galaxy clustering of the combined sample of Baryon Oscillation Spectroscopic Survey (B…
Galactic wind X-ray heating of the intergalactic medium during the Epoch of Reionization
Avery Meiksin, Sadegh Khochfar, Jan-Pieter Paardekooper +2
The diffuse soft X-ray emissivity from galactic winds is computed during the Epoch of Reionization (EoR). We consider two analytic models, a pressure-driven wind and a superbubble…
Observations of the galaxy cluster CIZA J2242.8+5301 with the Sardinia Radio Telescope
F. Loi, M. Murgia, F. Govoni +25
We observed the galaxy cluster CIZA J2242.8+5301 with the Sardinia Radio Telescope to provide new constraints on its spectral properties at high frequency. We conducted observation…
The Cluster-EAGLE project: velocity bias and the velocity dispersion - mass relation of cluster galaxies
Thomas Joshua Armitage, David. J. Barnes, Scott. T. Kay +4
We use the Cluster-EAGLE simulations to explore the velocity bias introduced when using galaxies, rather than dark matter particles, to estimate the velocity dispersion of a galaxy…
Exploring cosmic origins with CORE: mitigation of systematic effects
P. Natoli, M. Ashdown, R. Banerji +123
We present an analysis of the main systematic effects that could impact the measurement of CMB polarization with the proposed CORE space mission. We employ timeline-to-map simulati…
Exploring cosmic origins with CORE: gravitational lensing of the CMB
Anthony Challinor, Rupert Allison, Julien Carron +110
Lensing of the CMB is now a well-developed probe of large-scale clustering over a broad range of redshifts. By exploiting the non-Gaussian imprints of lensing in the polarization o…
Density distribution of the cosmological matter field
Anatoly Klypin, Francisco Prada, Juan Betancort-Rijo +1
The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in cosmology for estimates…
Tracing the cosmic web
Noam I Libeskind, Rien van de Weygaert, Marius Cautun +27
The cosmic web is one of the most striking features of the distribution of galaxies and dark matter on the largest scales in the Universe. It is composed of dense regions packed fu…
The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample: First measurement of Baryon Acoustic Oscillations between redshift 0.8 and 2.2
Metin Ata, Falk Baumgarten, Julian Bautista +60
We present measurements of the Baryon Acoustic Oscillation (BAO) scale in redshift-space using the clustering of quasars. We consider a sample of 147,000 quasars from the extended…
Analysis of the Amplitude of the Sunyaev-Zel'dovich Effect out to Redshift z=0.8
M. Lopez-Corredoira, C. M. Gutierrez, R. T. Genova-Santos
The interaction of the cosmic microwave background (CMB) with the hot gas in clusters of galaxies, the so-called Sunyaev--Zel'dovich (SZ) effect, is a very useful tool that allows…
Testing approximate predictions of displacements of cosmological dark matter halos
Emiliano Munari, Pierluigi Monaco, Jun Koda +3
We present a test to quantify how well some approximate methods, designed to reproduce the mildly non-linear evolution of perturbations, are able to reproduce the clustering of DM…
Exploring cosmic origins with CORE: effects of observer peculiar motion
C. Burigana, C. S. Carvalho, T. Trombetti +116
We discuss the effects on the CMB, CIB, and thermal SZ effect due to the peculiar motion of an observer with respect to the CMB rest frame, which induces boosting effects. We inves…
