First test of Verlinde's theory of Emergent Gravity using Weak Gravitational Lensing measurements
Margot M. Brouwer, Manus R. Visser, Andrej Dvornik +19
Verlinde (2016) proposed that the observed excess gravity in galaxies and clusters is the consequence of Emergent Gravity (EG). In this theory the standard gravitational laws are m…
Discovery of a supercluster in the ZOA in Vela
Renée C. Kraan-Korteweg, Michelle E. Cluver, Maciej Bilicki +5
We report the discovery of a potentially major supercluster that extends across the Galactic Plane in the constellation of Vela, at a mean recessional velocity of ~18,000 km/s. Rec…
Exploring Cosmic Origins with CORE: Inflation
CORE Collaboration, Fabio Finelli, Martin Bucher +129
We forecast the scientific capabilities to improve our understanding of cosmic inflation of CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a m…
The 2-degree Field Lensing Survey: photometric redshifts from a large new training sample to r<19.5
Christian Wolf, Andrew Johnson, Maciej Bilicki +13
We present a new training set for estimating empirical photometric redshifts of galaxies, which was created as part of the 2dFLenS project. This training set is located in a 700 sq…
Exploring Cosmic Origins with CORE: Cosmological Parameters
Eleonora Di Valentino, Thejs Brinckmann, Martina Gerbino +125
We forecast the main cosmological parameter constraints achievable with the CORE space mission which is dedicated to mapping the polarisation of the Cosmic Microwave Background (CM…
2dFLenS and KiDS: Determining source redshift distributions with cross-correlations
Andrew Johnson, Chris Blake, Alexandra Amon +16
We develop a statistical estimator to infer the redshift probability distribution of a photometric sample of galaxies from its angular cross-correlation in redshift bins with an ov…
Tracing low-mass galaxy clusters with radio relics: the discovery of Abell 3527-bis
F. de Gasperin, H. T. Intema, J. Ridl +6
Galaxy clusters undergo mergers that can generate extended radio sources called radio relics. Radio relics are the consequence of merger-induced shocks that propagate in the intra…
Robust predictions for an oscillatory bispectrum in Planck 2015 data from transient reductions in the speed of sound of the inflaton
Jesus Torrado, Bin Hu, Ana Achucarro
We update the search for features in the Cosmic Microwave Background (CMB) power spectrum due to transient reductions in the speed of sound, using Planck 2015 CMB temperature and p…
Uncertainties in primordial black-hole constraints on the primordial power spectrum
Yashar Akrami, Florian Kuhnel, Marit Sandstad
The existence (and abundance) of primordial black holes (PBHs) is governed by the power spectrum of primordial perturbations generated during inflation. So far no PBHs have been ob…
Cluster Mass Calibration at High Redshift: HST Weak Lensing Analysis of 13 Distant Galaxy Clusters from the South Pole Telescope Sunyaev-Zel'dovich Survey
T. Schrabback, D. Applegate, J. P. Dietrich +26
We present an HST/ACS weak gravitational lensing analysis of 13 massive high-redshift (z_median=0.88) galaxy clusters discovered in the South Pole Telescope (SPT) Sunyaev-Zel'dovic…
Cross-correlation of weak lensing and gamma rays: implications for the nature of dark matter
Tilman Tröster, Stefano Camera, Mattia Fornasa +12
We measure the cross-correlation between Fermi-LAT gamma-ray photons and over 1000 deg of weak lensing data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), t…
KiDS-450: Testing extensions to the standard cosmological model
Shahab Joudaki, Alexander Mead, Chris Blake +16
We test extensions to the standard cosmological model with weak gravitational lensing tomography using 450 deg of imaging data from the Kilo Degree Survey (KiDS). In these exte…
Halo ellipticity of GAMA galaxy groups from KiDS weak lensing
Edo van Uitert, Henk Hoekstra, Benjamin Joachimi +14
We constrain the average halo ellipticity of ~2 600 galaxy groups from the Galaxy And Mass Assembly (GAMA) survey, using the weak gravitational lensing signal measured from the ove…
How are galaxies assigned to halos? Searching for assembly bias in the SDSS galaxy clustering
Mohammadjavad Vakili, ChangHoon Hahn
Clustering of dark matter halos has been shown to depend on halo properties beyond mass such as halo concentration, a phenomenon referred to as halo assembly bias. Standard halo oc…
Bouncing cosmologies with dark matter and dark energy
Yi-Fu Cai, Antonino Marciano, Dong-Gang Wang +1
We review matter bounce scenarios where the matter content is dark matter and dark energy. These cosmologies predict a nearly scale-invariant power spectrum with a slightly red til…
Not a Copernican observer: biased peculiar velocity statistics in the local Universe
Wojciech A. Hellwing, Adi Nusser, Martin Feix +1
We assess the effect of the local large scale structure on the estimation of two-point statistics of the observed radial peculiar velocities of galaxies. A large N-body simulation…
