Extending empirical constraints on the SZ-mass scaling relation to higher redshifts via HST weak lensing measurements of nine clusters from the SPT-SZ survey at $zgtrsim1$

Posted by klaurent MIT

Kavli Affiliate: Michael A. McDonald | First 5 Authors: Hannah Zohren, Tim Schrabback, Sebastian Bocquet, Martin Sommer, Fatimah Raihan | Summary: We present a Hubble Space Telescope (HST) weak gravitational lensing study of nine distant and massive galaxy clusters with redshifts $1.0 lesssim z lesssim 1.7$ ($z_mathrm{median} = 1.4$) and Sunyaev Zel’dovich (SZ) detection significance […]

A comparison between compactly supported rigid and $pmb{mathscr{D}}$-module cohomology

Posted by klaurent Tokyo

Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, Christopher Lazda, , , | Summary: The goal of this article is to prove a comparison theorem between rigid cohomology and cohomology computed using the theory of arithmetic $mathscr{D}$-modules. To do this, we construct a specialisation functor from Le Stum’s category of constructible isocrystals to […]
