The BUFFALO HST Survey

Jean-Paul Richard Kneib, Pascale Jablonka, Huanyuan Shan, Hakim Atek, David Richard Harvey, Benjamin Yvan Alexandre Clement

The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope (HST) Treasury program taking data from 2018 to 2020. BUFFALO will expand existing coverage of the Hubble Frontier Fields ...

Measuring subhalo mass in redMaPPer clusters with CFHT Stripe 82 Survey

Jean-Paul Richard Kneib, Huanyuan Shan

We use the shear catalogue from the CFHT Stripe-82 Survey to measure the subhalo masses of satellite galaxies in redMaPPer clusters. Assuming a Chabrier initial mass function and a truncated NFW model for the subhalo mass distribution, we find that the sub ...

MultiDarkLens Simulations: weak lensing light-cones and data base presentation

Jean-Paul Richard Kneib, Huanyuan Shan

In this paper we present a large data base of weak lensing light cones constructed using different snapshots from the Big MultiDark simulation (BigMDPL). The ray-tracing through different multiple plane has been performed with the GLAMER code accounting bo ...

Lensing is low: cosmology, galaxy formation or new physics?

Huanyuan Shan

We present high signal-to-noise galaxy-galaxy lensing measurements of the Baryon Oscillation Spectroscopic Survey constant mass (CMASS) sample using 250 deg(2) of weak-lensing data from Canada-France-Hawaii Telescope Lensing Survey and Canada-France-Hawaii ...

ESM-SnowMIP: assessing snow models and quantifying snow-related climate feedbacks

Charles Fierz, Huanyuan Shan, Nander Wever

This paper describes ESM-SnowMIP, an international coordinated modelling effort to evaluate current snow schemes, including snow schemes that are included in Earth system models, in a wide variety of settings against local and global observations. The proj ...

Stochastic bias of colour-selected BAO tracers by joint clustering-weak lensing analysis

Jean-Paul Richard Kneib, David Schlegel, Huanyuan Shan

The baryon acoustic oscillation (BAO) feature in the two-point correlation function of galaxies supplies a standard ruler to probe the expansion history of the Universe. We study here several galaxy selection schemes, aiming at building an emission-line ga ...

The Mass-Concentration Relation and the Stellar-to-halo Mass Ratio in the CFHT Stripe 82 Survey

Jean-Paul Richard Kneib, Huanyuan Shan

We present a new measurement of the mass-concentration relation and the stellar-to-halo mass ratio over the halo-mass range 5 x 10(12) to 2 x 10(14) M circle dot. To achieve this, we use weak lensing measurements from the Canada-France-Hawaii Telescope Str ...

DESI and DECaLS (D&D): galaxy-galaxy lensing measurements with 1 per cent survey and its forecast

Jean-Paul Richard Kneib, Huanyuan Shan

The shear measurement from the Dark Energy Camera Legacy Survey (DECaLS) provides an excellent opportunity for galaxy-galaxy lensing study with the Dark Energy Spectroscopic Instrument (DESI) galaxies, given the large (similar to 9000 deg(2)) sky overlap. ...

The extraordinary amount of substructure in the Hubble Frontier Fields cluster Abell 2744

Jean-Paul Richard Kneib, Huanyuan Shan, Hakim Atek, Benjamin Yvan Alexandre Clement, David Richard Harvey, Markus Rexroth

We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z = 0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e. at R < 1 Mpc from the brightest cluster galaxy, reveals eight substructures ...

Weak-lensing mass calibration of the Atacama Cosmology Telescope equatorial Sunyaev-Zeldovich cluster sample with the Canada-France-Hawaii telescope stripe 82 survey

Jean-Paul Richard Kneib, Huanyuan Shan

Mass calibration uncertainty is the largest systematic effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from the Canada-France-Hawaii Telescope Stripe 82 Survey for galaxy clusters select ...

First galaxy-galaxy lensing measurement of satellite halo mass in the CFHT Stripe-82 Survey

Jean-Paul Richard Kneib, Huanyuan Shan

We select satellite galaxies from the galaxy group catalogue constructed with the Sloan Digital Sky Survey spectroscopic galaxies and measure the tangential shear around these galaxies with the source catalogue extracted from the Canada-France-Hawaii Teles ...

First measurement of the cross-correlation of CMB lensing and galaxy lensing

Jean-Paul Richard Kneib, Huanyuan Shan

We measure the cross-correlation of cosmic microwave background (CMB) lensing convergence maps derived from Atacama Cosmology Telescope data with galaxy lensing convergence maps as measured by the Canada-France-Hawaii Telescope Stripe 82 Survey. The CMB-ga ...

Overview of the DESI Legacy Imaging Surveys

Jean-Paul Richard Kneib, Anand Stéphane Raichoor, David Schlegel, Huanyuan Shan, Timothée Guy Olivier Delubac, Elodie Marie Charlène Savary, Arjun Dey, Claudio Gorgoni, Zhou Xue

The DESI Legacy Imaging Surveys (http://legacysurvey.org/) are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Survey) that will jointly image approximate to 14,000 ...
