We build a novel realization of dark bubble cosmology in non-supersymmetric
string theory. Among the simplest models in ten dimensions, the type 0'B
orientifold is the unique option which yields a scale-separated construction.
The resulting...

We introduce the THESAN-ZOOM project, a comprehensive suite of
high-resolution zoom-in simulations of high-redshift () galaxies
selected from the THESAN simulation volume. This sample encompasses a diverse
range of halo masses, wi...

We present the age determination of 13 globular clusters dynamically
associated with the Gaia-Sausage-Enceladus (GSE) merger event, as part of the
CARMA project effort to trace the Milky Way assembly history. We used deep and
homogeneous ar...

Current cosmological data are well-described by the Lambda-Cold Dark Matter
(CDM) model, which assumes adiabatic initial conditions for the
primordial density perturbations. This agreement between data and theory
enables strong con...

We explore the effect of variations in the Population III (Pop III) initial
mass function (IMF) and star-by-star feedback on early galaxy formation and
evolution using the Aeos simulations. We compare simulations with two different

Strategic decision-making involves interactive reasoning where agents adapt
their choices in response to others, yet existing evaluations of large language
models (LLMs) often emphasize Nash Equilibrium (NE) approximation, overlooking
the m...

We propose an interpretation of the observed cosmic acceleration in Friedmann
universes as a gravitational bifurcation. Mathematically this becomes possible
due to the degenerate nature of the Friedmann equations leading to their versal

Artificial Intelligence (AI) technology such as Large Language Models (LLMs)
have become extremely popular in creating code. This has led to the conjecture
that future software jobs will be exclusively conducted by LLMs, and the
