Toward the fabric of the Milky Way I. The density of disk streams from a local pc volume
Sebastian Ratzenböck, João Alves, Emily L. Hunt +3
We studied 12 disk streams found in a 250 pc volume in the solar neighborhood, which we define as coeval and comoving stellar structures with aspect ratios greater than 3:1…
The star formation history of the Sco-Cen association. Coherent star formation patterns in space and time
Sebastian Ratzenböck, Josefa E. Großschedl, João Alves +13
We reconstruct the star formation history of the Sco-Cen OB association using a novel high-resolution age map of the region. We develop an approach to produce robust ages for Sco-C…
Significance Mode Analysis (SigMA) for hierarchical structures. An application to the Sco-Cen OB association
Sebastian Ratzenböck, Josefa E. Großschedl, Torsten Möller +3
We present a new clustering method, Significance Mode Analysis (SigMA), to extract co-spatial and co-moving stellar populations from large-scale surveys such as ESA Gaia. The metho…
The Oph region revisited with Gaia EDR3
Natalie Grasser, Sebastian Ratzenböck, João Alves +10
Context. Young and embedded stellar populations are important probes of the star formation process. Paradoxically, we have a better census of nearby embedded young populations than…
