Today marks the start of our publishing activities in the field of Astronomy: our new journal SciPost Astronomy has been officially launched with the publication of its very first paper:

Bonsai-SPH: A GPU accelerated astrophysical Smoothed Particle Hydrodynamics code
by Jeroen Bédorf and Simon Portegies Zwart.

Warm congratulations to the authors for pioneering this new title!

SciPost Astronomy represents the first of a series of new journals in fields beyond Physics, which we are currently planning to establish as part of our broad expansion strategy.

"Exceptional Chern-Simons-Matter dualities" by Clay Cordova, Po-Shen Hsin, Kantaro Ohmori has received the Select label. Warm congratulations to the author!

This well-structured paper fills the gap in literature regarding how the exceptional groups fit into topological quantum field theories for classical Lie groups. The authors first give a concise, helpful presentation of some mathematically rigorous facts about topological quantum field theories with exceptional gauge groups. Then, they developed a set of new families of Chern-Simons theories. This is done exploiting the conformal embedding technique for the corresponding chiral algebras, as well as with the aid of some results concerning more formal aspects of Kac-Moody algebras. With the new dualities for topological Chern-Simons theories, the authors proceed to formulate an array of conjectures regarding the Chern-Simons-matter dualities with scalar matter. Finally, they use them to determine candidate phase diagrams of time-reversal invariant G2 gauge theory coupled to either an adjoint fermion, or two fundamental fermions.

"General continuum model for twisted bilayer graphene and arbitrary smooth deformations" by Leon Balents has received the Select label. Warm congratulations to the author!

Moiré patterns can affect the low energy electronic structure in twisted bilayer graphene and provide an unprecedented platform for correlated electron physics. In this clear paper, the author uses a simple derivation of a continuum Hamiltonian to calculate the low energy electronic band structure. The original continuum model written in the momentum space is hard to use when lattice relaxation and strain effects come in. To solve this issue, the current paper derives the continuum model in real space, which can easily incorporate strain effects. With this new method, the author provides a unified method to study twisted graphene structures including all the important electronic structure physics. It may also be helpful for future studies of disorder effects in these systems.
