Type Ia Supernova Distance Modulus Bias and Dispersion From K-correction Errors: A Direct Measurement Using Lightcurve Fits to Observed Spectral Time Series
C. Saunders, G. Aldering, P. Antilogus +34
We estimate systematic errors due to K-corrections in standard photometric analyses of high redshift Type Ia supernovae. Errors due to K-correction occur when the spectral template…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
Implications of the scalar tilt for the tensor-to-scalar ratio
Paolo Creminelli, Sergei Dubovsky, Diana López Nacir +4
We investigate the possible implications of the measured value of the scalar tilt for the tensor-to-scalar ratio in slow-roll, single-field inflationary models. The measu…
Hierarchical probabilistic inference of cosmic shear
Michael D. Schneider, David W. Hogg, Philip J. Marshall +4
Point estimators for the shearing of galaxy images induced by gravitational lensing involve a complex inverse problem in the presence of noise, pixelization, and model uncertaintie…
Cosmological implications of baryon acoustic oscillation (BAO) measurements
Éric Aubourg, Stephen Bailey, Julian E. Bautista +90
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…
Friedmann's Equations in All Dimensions and Chebyshev's Theorem
Shouxin Chen, Gary W. Gibbons, Yijun Li +1
This short but systematic work demonstrates a link between Chebyshev's theorem and the explicit integration in cosmological time and conformal time of the Friedmann equatio…
Tests of redshift-space distortions models in configuration space for the analysis of the BOSS final data release
Martin White, Beth Reid, Chia-Hsun Chuang +4
Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on th…
Velocity Bias from the Small Scale Clustering of SDSS-III BOSS Galaxies
Hong Guo, Zheng Zheng, Idit Zehavi +6
We present the measurements and modelling of the projected and redshift-space clustering of CMASS galaxies in the Sloan Digital Sky Survey-III Baryon Oscillation Spectroscopic Surv…
Toward an Understanding of Foreground Emission in the BICEP2 Region
Raphael Flauger, J. Colin Hill, David N. Spergel
BICEP2 has reported the detection of a degree-scale B-mode polarization pattern in the Cosmic Microwave Background (CMB) and has interpreted the measurement as evidence for primord…
Daughters mimic sterile neutrinos (almost!) perfectly
Jasper Hasenkamp
Since only recently, cosmological observations are sensitive to hot dark matter (HDM) admixtures with sub-eV mass, < eV, that are not fully-thermalised, $…
IGM Constraints from the SDSS-III/BOSS DR9 Ly-alpha Forest Flux Probability Distribution Function
Khee-Gan Lee, Joseph P. Hennawi, David N. Spergel +13
The Ly forest transmission probability distribution function (PDF) is an established probe of the intergalactic medium (IGM) astrophysics, especially the temperature-density rel…
Constraining Primordial Non-Gaussianity with Moments of the Large Scale Density Field
Qingqing Mao, Andreas A. Berlind, Cameron K. McBride +3
We use cosmological N-body simulations to investigate whether measurements of the moments of large-scale structure can yield constraints on primordial non-Gaussianity. We measure t…
Non-Gaussianity after BICEP2
Guido D'Amico, Matthew Kleban
We analyze primordial non-Gaussianity in single field inflationary models when the tensor/scalar ratio is large. Our results show that detectable levels of non-Gaussianity $f_{NL}…
A 2.5% measurement of the growth rate from small-scale redshift space clustering of SDSS-III CMASS galaxies
Beth A. Reid, Hee-Jong Seo, Alexie Leauthaud +2
We perform the first fit to the anisotropic clustering of SDSS-III CMASS DR10 galaxies on scales of ~ 0.8 - 32 Mpc/h. A standard halo occupation distribution model evaluated near t…
BICEP2 in Corpuscular Description of Inflation
Gia Dvali, Cesar Gomez
A corpuscular quantum description of inflation shows that there is no fundamental problem with trans-Planckian excursions of the inflaton field up to about 100 Planck masses, with…
Deep radio observations of the radio halo of the bullet cluster 1E 0657-55.8
Timothy W. Shimwell, Shea Brown, Ilana J. Feain +3
We present deep 1.1-3.1 GHz Australia Telescope Compact Array observations of the radio halo of the bullet cluster, 1E 0657-55.8. In comparison to existing images of this radio hal…
Neutrinos help reconcile Planck measurements with both Early and Local Universe
Cora Dvorkin, Mark Wyman, Douglas H. Rudd +1
In light of the recent BICEP2 B-mode polarization detection, which implies a large inflationary tensor-to-scalar ratio r_{0.05}=0.2^{+0.07}_{-0.05}, we re-examine the evidence for…
