Baryon acoustic oscillations in the Lya forest of BOSS DR11 quasars

Jean-Paul Richard Kneib, David Schlegel, Timothée Guy Olivier Delubac

We report a detection of the baryon acoustic oscillation (BAO) feature in the flux-correlation function of the Ly alpha forest of high-redshift quasars with a statistical significance of five standard deviations. The study uses 137 562 quasars in the redsh ...

The Sdss-Iv Extended Baryon Oscillation Spectroscopic Survey: Quasar Target Selection

Jean-Paul Richard Kneib, Johan Comparat, David Schlegel, Pierre Laurent

As part of the Sloan Digital Sky Survey (SDSS) IV the extended Baryon Oscillation Spectroscopic Survey (eBOSS) will improve measurements of the cosmological distance scale by applying the Baryon Acoustic Oscillation (BAO) method to quasar samples. eBOSS wi ...

Spectroscopic needs for imaging dark energy experiments

Jean-Paul Richard Kneib, Johan Comparat, Anja Von der Linden

Ongoing and near-future imaging-based dark energy experiments are critically dependent upon photometric redshifts (a.k.a. photo-z's): i.e., estimates of the redshifts of objects based only on flux information obtained through broad filters. Higher-quality, ...

Search for the Dark Photon and the Dark Higgs Boson at Belle

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Dipanwita Dutta, Xiao Wang

The dark photon A' and the dark Higgs boson h' are hypothetical constituents featured in a number of recently proposed dark sector models. Assuming prompt decays of both dark particles, we search for their production in the so-called Higgstrahlung channel ...

Silicon-on-Insulator Technology for Bioluminescence Imaging and Application to a Switching Photodetector

Maher Kayal, Adil Koukab, Denis Sallin, Nisrina Abdo

This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a ...

Planck 2013 results. XIX. The integrated Sachs-Wolfe effect

Julien Lesgourgues, Slobodan Ilic, Fabio Finelli

Based on cosmic microwave background (CMB) maps from the 2013 Planck Mission data release, this paper presents the detection of the integrated Sachs-Wolfe (ISW) effect, that is, the correlation between the CMB and large-scale evolving gravitational potenti ...

Cosmology From Gravitational Lens Time Delays And Planck Data

Frédéric Courbin, Georges Meylan, Malte Tewes

Under the assumption of a flat Lambda CDM cosmology, recent data from the Planck satellite point toward a Hubble constant that is in tension with that measured by gravitational lens time delays and by the local distance ladder. Prosaically, this difference ...

Weak lensing mass map and peak statistics in Canada-France-Hawaii Telescope Stripe 82 survey

Jean-Paul Richard Kneib, Frédéric Courbin, Georges Meylan, Johan Comparat, Huanyuan Shan

We present a weak lensing mass map covering similar to 124 deg(2) of the Canada-France-Hawaii Telescope Stripe 82 Survey (CS82). We study the statistics of rare peaks in the map, including peak abundance, the peak-peak correlation functions and the tangent ...
