The Alignment of Dark Matter Halos with the Cosmic Web
We investigate the orientation of the axes and angular momentum of dark matter halos with respect to their neighboring voids using high-resolution N-body...
The Alma catalogue of OB stars – III. A cross-match with Gaia DR3 and an extension based on new spectral classifications
We present the third installment of the Alma Luminous Star catalogue, aimed at creating the most comprehensive and clean sample of Galactic massive stars. This...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): I. Motivation, sample, data reduction, and results overview
Context. The outer regions of planetary systems host dusty debris discs analogous to the Kuiper belt (exoKuiper belts), which provide crucial constraints on...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): II. The radial structure of debris discs
Context. Debris discs are populated by belts of planetesimals, whose structure carries dynamical imprints of planets and the formation and evolutionary history...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): III. The vertical structure of debris disks
Context. Debris disks ─ collisionally sustained belts of dust and sometimes gas around main sequence stars ─ are remnants of planet formation processes and are...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): IV. CO gas imaging and overview
Context. CO gas is detected in a significant number (~20) of debris discs (exoKuiper belts), but understanding its origin and evolution remains elusive. Crucial...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): IX. Gas-driven origin for the continuum arc in the debris disc of HD121617
Context. Debris discs were long considered to be largely gas-free environments, where dynamical evolution is governed primarily by collisional fragmentation...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): V. Comparison between scattered light and thermal emission
Context. Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved...
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS): VI. Asymmetries and offsets
Context. Asymmetries in debris discs provide unique clues to understand the evolution and architecture of planetary systems. Previous studies of debris discs at...
