Full-transport radiation GRMHD simulations show super-Eddington black hole accretion is geometrically thick, drives strong outflows, and radiates with very low efficiency (below about 0.5% at 150 times Eddington).
A semi-analytic model shows dense early star clusters can grow 1000-solar-mass black hole seeds to ~10^7 solar masses within ~100 million years, predicting tens of tidal disruptions per year from Little Red Dots at z=4-6.
The counterjet dominates PeV photon production in Cyg X-3 due to longer interaction paths through the donor star's wind at low inclination.
A new IXPE observation finds no X-ray polarization from MAXI J1744-294 and uses the 1.3% upper limit to constrain the accretion disk inclination to roughly 38-71 degrees, depending on spin and atmosphere albedo.
IXPE, launched in December 2021, is the first dedicated imaging X-ray polarimetry observatory and has measured X-ray polarization for about 110 cosmic sources.
