Discovery of a radio relic in the low mass, merging galaxy cluster PLCK G200.9-28.2
Ruta Kale, Daniel R. Wik, Simona Giacintucci +5
Radio relics at the peripheries of galaxy clusters are tracers of the elusive cluster merger shocks. We report the discovery of a single radio relic in the galaxy cluster PLCK G200…
Simulations for 21 cm radiation lensing at EoR redshifts
Alessandro Romeo, R. Benton Metcalf, Alkistis Pourtsidou
We introduce simulations aimed at assessing how well weak gravitational lensing of 21cm radiation from the Epoch of Reionization () can be measured by an SKA-like radio t…
The ellipticity of galaxy cluster halos from satellite galaxies and weak lensing
Tae-hyeon Shin, Joseph Clampitt, Bhuvnesh Jain +4
We study the ellipticity of galaxy cluster halos as characterized by the distribution of cluster galaxies and as measured with weak lensing. We use monte-carlo simulations of ellip…
