The apparent Large Magellanic Cloud star cluster age gap

Jonathan H. Klos, Andres E. Piatti ยท 2026

In the Large Magellanic Cloud, very few clusters have been observed with ages between 4 and 11 Gyr. This phenomenon is sometimes referred to as the `LMC age gap'. We construct a model of the cluster aโ€ฆ

Crosscap Defects

Nadav Drukker, Shota Komatsu, Anders Wallberg ยท 2026

We introduce a novel class of defects, termed {\it crosscap defects}, in conformal field theory (CFT) in general dimensions. These arise from quotienting the spacetime by a $\mathbb{Z}_2$ automorphismโ€ฆ
