Cool Core Bias in Sunyaev-Zel’dovich Galaxy Cluster Surveys

Kavli Affiliate: Bradford Benson | First 5 Authors: Henry W. Lin, Michael McDonald, Bradford Benson, Eric Miller, | Summary: Sunyaev-Zeldovich (SZ) surveys find massive clusters of galaxies by measuring the inverse Compton scattering of cosmic microwave background off of intra-cluster gas. The cluster selection function from such surveys is expected to be nearly independent of […]

Multiple Soft Limits of Cosmological Correlation Functions

Kavli Affiliate: Austin Joyce | First 5 Authors: Austin Joyce, Justin Khoury, Marko Simonović, , | Summary: We derive novel identities satisfied by inflationary correlation functions in the limit where two external momenta are taken to be small. We derive these statements in two ways: using background-wave arguments and as Ward identities following from the […]

Delensing Galaxy Surveys

Kavli Affiliate: Chihway Chang | First 5 Authors: Chihway Chang, Bhuvnesh Jain, , , | Summary: Weak gravitational lensing can cause displacements, magnification, rotation and shearing of the images of distant galaxies. Most studies focus on the shear and magnification effects since they are more easily observed. In this paper we focus on the effect […]

Properties of type Ia supernovae inside rich galaxy clusters

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Henrique S. Xavier, Ravi R. Gupta, Masao Sako, Chris B. D’Andrea, Joshua A. Frieman | Summary: We used the GMBCG galaxy cluster catalogue and SDSS-II supernovae data with redshifts measured by the BOSS project to identify 48 SNe Ia residing in rich galaxy clusters and compare […]

Quenching and Channeling of Nuclear Recoils in NaI[Tl]: Implications for Dark Matter Searches

Kavli Affiliate: Juan I. Collar | First 5 Authors: J. I. Collar, , , , | Summary: A new experimental evaluation of the quenching factor for nuclear recoils in NaI[Tl] is described. Systematics affecting previous measurements are addressed by careful characterization of the emission spectrum of the neutron source, use of a small scintillator coupled […]
