Evidence for a thermal pressure deficit in galaxy groups from the tSZ effect and weak lensing
Jared Siegel, Alexandra Amon, Jenny E. Greene +3
Measurements of the thermal Sunyaev-Zel'dovich (tSZ) effect have yet to form a consistent picture of the thermodynamic state of the gas in the intracluster medium: their interpreta…

Joint X-ray, kinetic Sunyaev-Zeldovich, and weak lensing measurements: toward a consensus picture of efficient gas expulsion from groups and clusters
Jared Siegel, Alexandra Amon, Ian G. McCarthy +7
There is no consensus on how baryon feedback shapes the underlying matter distribution from either simulations or observations. We confront the uncertain landscape by jointly analy…

UNCOVERing the High-redshift AGN Population among Extreme UV Line Emitters
Helena Treiber, Jenny Greene, John R. Weaver +23
JWST has revealed diverse new populations of high-redshift () AGN and extreme star-forming galaxies that challenge current models. In this paper, we use rest-frame UV em…
