Schematic of the proposed mechanism for accretion disk formation and BH growth. The illustration presents the evolution of a UCD from a massive gas cloud to present-day UCDs with MBHs. The main idea presented is that the formation of AGB stars over time can undergo gas ejection which can infall towards an IMBH forming an accretion disk around it. The schematic also highlights key mechanisms present, such as the formation of new stars within the accretion disk that can populate the entire UCD. Leading to a key prediction for the proposed mechanism, being the creation of a new stellar population

Three-dimensional visualizations of the eight CM meteorite targets used in this study: Murchison (MU) and Aguas Zarcas (AG), both before and after impact, specifically highlighting the largest resulting fragments. These images are organized by extent of fragmentation. Second shots are indicated by a number 2 in brackets. Values within parentheses represent the mass ratio of the largest fragment to the initial target, ⁠Ml/Mt. Projectile trajectories are indicated by arrows, while the tomographic cross-sectional planes corresponding to Fig. 5 are marked in yellow.

Kim et al. (2018). In both the observational and convolved images, the GMVA beam is represented by an ellipse.

Wide-field view of the Eagle Nebula (M16), based on a recoloured DSS2 Blue image obtained from photographic plates from the UK Schmidt Telescope. The four regions of study: Spire, SFO30, I–II–III base, and IV base are labelled. Striped segments show the inferred plane-of-sky magnetic-field orientation derived from 850-μm dust polarization observations from the BISTRO survey, carried out with the JCMT. The dashed boundary indicates the approximate extent of the BISTRO-mapped region. Stars mark selected massive members of the ionizing cluster NGC 6611. The O7 II star NGC 6611 246 (BD⁠) is highlighted; its projected proximity to both the Spire and SFO30 suggests that it may contribute significantly to the local ionization and feedback environment within these structures.
