Tracing Dark Matter in the Central Regions of Galaxy Clusters Using Galaxies, Gas, and Intracluster Light in TNG300: Connections to Cluster Dynamical State
Recent studies have highlighted the potential of intracluster light (ICL) as a dark matter tracer. Moreover, the ICL co-evolves with the brightest cluster galaxy (BCG) and the host cluster, making it a valuable tool for understanding cluster dynamics. In this study, we utilize 426 galaxy clusters (with total mass $M_{\rm tot}>10^{14} M_{\odot}$ at $z=0$) simulated in the cosmological hydrodynamical simulation Illustris TNG300 to compare the spatial distributions of dark matter, member galaxies,…

The ITTAGE indirect branch predictor
Modern CPUs are actually pretty good at predicting the indirect branch inside an interpreter loop, _contra_ the conventional wisdom. We take a deep dive into the ITTAGE indirect branch prediction algorithm, which is capable of making those predictions, and draw some connections to some other interests of mine in the areas of fuzzing and reinforcement learning.

Are there any established easily electrical connectors that can be 3D printed cheaply (like, <0.10€ each)? I'm thinking of 0.3mm bare copper wire threaded through the parts and making contact with each other backed by plastic springs, but designing them from scratch would take many iterations.
Ideally, I'd like to make connections in up to 10 places, each with 4 pins, from a single FDM part, wire them to a single small PCB (3 bus pins plus one per place) for <1€ in parts.…
