Quantification of the multi-streaming effect in Redshift Space Distortion
Yi Zheng, Pengjie Zhang, Minji Oh
Both multi-streaming (random motion) and bulk motion cause the Finger-of-God (FoG) effect in redshift space distortion (RSD). We apply a direct measurement of the multi-streaming e…
The cosmological principle is not in the sky
Chan-Gyung Park, Hwasu Hyun, Hyerim Noh +1
The homogeneity of matter distribution at large scales, known as the cosmological principle, is a central assumption in the standard cosmological model. The case is testable though…
Consistency of the Planck CMB data and CDM cosmology
Arman Shafieloo, Dhiraj Kumar Hazra
We test the consistency between Planck temperature and polarization power spectra and the concordance model of Cold Dark Matter cosmology (CDM) within the framework of Cross…
Metastable Dark Energy with Radioactive-like Decay
Arman Shafieloo, Dhiraj Kumar Hazra, Varun Sahni +1
We propose a new class of metastable dark energy (DE) phenomenological models in which the DE decay rate does not depend on external parameters such as the scale factor or the curv…
Cosmological constraints from the redshift dependence of the Alcock-Paczynski effect: application to the SDSS-III BOSS DR12 galaxies
Xiao-Dong Li, Changbom Park, Cristiano G. Sabiu +5
We apply the methodology developed in \cite{Li2014,Li2015} to BOSS DR12 galaxies and derive cosmological constraints from the redshift dependence of the Alcock-Paczynski (AP) effec…
SPT-GMOS: A Gemini/GMOS-South Spectroscopic Survey of Galaxy Clusters in the SPT-SZ Survey
M. B. Bayliss, J. Ruel, C. W. Stubbs +75
We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified…
Turbulence and Vorticity in Galaxy Clusters Generated by Structure Formation
F. Vazza, T. W. Jones, M. Brüggen +4
Turbulence is a key ingredient for the evolution of the intracluster medium, whose properties can be predicted with high resolution numerical simulations. We present initial result…
Growth of perturbations in nonlocal gravity with non-CDM background
Sohyun Park, Arman Shafieloo
We re-analyze the nonlocal gravity model of Deser and Woodard which was proposed to account for the current phase of cosmic acceleration. We show that the growth of perturbations p…
Measuring neutrino mass imprinted on the anisotropic galaxy clustering
Minji Oh, Yong-Seon Song
The anisotropic galaxy clustering of large scale structure observed by the Baryon Oscillation Spectroscopic Survey Data Release 11 is analyzed to probe the sum of neutrino mass in…
Beyond Kaiser bias: mildly non-linear two-point statistics of densities in distant spheres
C. Uhlemann, S. Codis, J. Kim +5
Simple parameter-free analytic bias functions for the two-point correlation of densities in spheres at large separation are presented. These bias functions generalize the so-called…
Strong Lensing In The Inner Halo Of Galaxy Clusters
C. Saez, L. E. Campusano, E. S. Cypriano +2
We present an axially symmetric formula to calculate the probability of finding gravitational arcs in galaxy clusters, being induced by their massive dark matter haloes, as a funct…
Model-independent test of the FLRW metric, the flatness of the Universe, and non-local measurement of
Benjamin L'Huillier, Arman Shafieloo
Using measurements of and from the Baryon Oscillation Spectroscopic Survey (BOSS) DR12 and luminosity distances from the Joint Lightcurve Analysis (JLA) co…
Primordial features and Planck polarization
Dhiraj Kumar Hazra, Arman Shafieloo, George F. Smoot +1
With the Planck 2015 Cosmic Microwave Background (CMB) temperature and polarization data, we search for possible features in the primordial power spectrum (PPS). We revisit the Wig…
Discovery of a Supercluster at 0.91 and Testing the CDM Cosmological Model
J. -W. Kim, M. Im, S. -K. Lee +13
The CDM cosmological model successfully reproduces many aspects of the galaxy and structure formation of the universe. However, the growth of large-scale structures (LSSs) in th…
The Carnegie-Chicago Hubble Program. I. An Independent Approach to the Extragalactic Distance Scale Using only Population II Distance Indicators
Rachael L. Beaton, Wendy L. Freedman, Barry F. Madore +15
We present an overview of the Carnegie-Chicago Hubble Program, an ongoing program to obtain a 3 per cent measurement of the Hubble constant using alternative methods to the traditi…
Cosmological Constraints from Galaxy Clusters in the 2500 square-degree SPT-SZ Survey
T. de Haan, B. A. Benson, L. E. Bleem +74
(abridged) We present cosmological constraints obtained from galaxy clusters identified by their Sunyaev-Zel'dovich effect signature in the 2500 square degree South Pole Telescope…
Time Delay Analysis of the Lensed Quasar SDSS J1001+5027
Amir Aghamousa, Arman Shafieloo
We modify the algorithm we proposed before in Aghamousa & Shafieloo (2015) on time delay estimation of the strong lens systems incorporating weighted cross-correlation and weighted…
Probing scalar tensor theories for gravity in redshift space
Cristiano G. Sabiu, David F. Mota, Claudio Llinares +1
We present measurements of the spatial clustering statistics in redshift space of various scalar field modified gravity simulations. We utilise the two-point and the three-point co…
Study on the mapping of dark matter clustering from real space to redshift space
Yi Zheng, Yong-Seon Song
The mapping of dark matter clustering from real space to redshift space introduces the anisotropic property to the measured density power spectrum in redshift space, known as the r…

M. T. Soumagnac, R. Barkana, C. G. Sabiu +5
Baryon Acoustic Oscillations (BAOs) in the early Universe are predicted to leave an as yet undetected signature on the relative clustering of total mass versus luminous matter. A d…
