Title: Zooming out: what a broader view is telling us about stellar and substellar conglomerates
Abstract: Measuring the distributions of ages and masses of low-mass stars and substellar sources in different young environments requires a thorough census of this specific population. Typically, studies have searched for defined conglomerate members using signatures of youth (variability, emission lines, infrared (IR) excess emission, X-ray emission), proper motions, and optical and near-IR color-magnitude diagrams. Given the access to the most recent all-sky surveys, better statistics are now in place, and a series of observational and theoretical challenges keep the field ongoing. Given a wider and uniform spatial coverage of ultra-cool dwarf sources, the diversity of spatial structures and the traditional definition of luminosity functions in spatially-delineated conglomerates should be revisited. Some recent examples are presented.
