Black Hole and Magnetar Studies with the Imaging X-ray Polarimetry Explorer
The Imaging X-ray Polarimetry Explorer (IXPE) mission was launched on December 9, 2021 and has observed a number of galactic and extragalactic X-ray sources. I report here on the IXPE observations of the High Mass X-Ray Binary Cyg X-1. IXPE detected a strong 2-8 keV polarization signal constraining the origin of the X-ray emission and the configuration of matter close to the Cyg X-1 black hole....

The Age of Discovery with JWST: Excavating the First Massive Black Holes and First Galaxies
The James Webb Space Telescope (JWST) is opening a new window of the most distant universe and will unveil the early growth of supermassive black holes (BHs) in the first galaxies.The existence of supermassive massive BHs observed when the universe was younger than one billion years strongly constrains their formation pathway and provides a crucial hint to understand the coevolution between BHs...
