Late Time Modification of Structure Growth and the S8 Tension

Kavli Affiliate: Chihway Chang | First 5 Authors: Meng-Xiang Lin, Bhuvnesh Jain, Marco Raveri, Eric J. Baxter, Chihway Chang | Summary: The $S_8$ tension between low-redshift galaxy surveys and the primary CMB signals a possible breakdown of the $Lambda$CDM model. Recently differing results have been obtained using low-redshift galaxy surveys and the higher redshifts probed […]

On the dominant role of wind in the quasar feedback mode in the late stage evolution of massive elliptical galaxies

Kavli Affiliate: Yingjie Peng | First 5 Authors: , , , , | Summary: In this paper we investigate the role of AGN feedback on the late stage evolution of elliptical galaxies by performing high-resolution hydrodynamical simulation in the {it MACER} framework. By comparing models that take into account different feedback mechanisms, namely AGN and […]

Overview and First Results of EUSO-SPB2

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Johannes Eser, Angela V. Olinto, Lawrence Wiencke, , | Summary: Observing ultra-high energy cosmic rays (UHECR) and very high energy (VHE) neutrinos from space is a promising way to measure their extremely low fluxes by significantly increasing the observed volume. The Extreme Universe Space Observatory on […]
