The Disrupted Chemical Enrichment History of the Milky Way Driven by Gas Accretion
The Astrophysical Journal LettersAs the only galaxy enabling temporally resolved observations from an internal vantage point, the Milky Way as a galaxy offers unique insights into galactic chemical enrichment history, establishment of fundamental scaling relations, and the underlying ...

Similar Signatures of Coplanar Gas Inflow and Disk Warps in Galactic Gas Kinematic Maps
The Astrophysical Journal, 2023 Hydrodynamic simulations suggest that galactic gas disks form when coplanar gas spirals into the inner regions of the disk. We recently presented a simple modified accretion disk model of viscous galactic disks in which star formation is fed by a radial ...

Interdisciplinary Medicine, EarlyView.Liquid biopsy uses non‐invasive sampling of blood or body fluids to isolate circulating analytes, including circulating tumor DNA, circulating tumor cells, extracellular vesicles, and RNA. These are analyzed using next‐generation sequencing, qPCR, and proteomics to inform cancer detection, monitoring, and characterization. Figure created with BioRender.

How ventures maintain stakeholder support amidst operational legitimacy threats
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary We explore how ventures mitigate operational legitimacy threats—threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition. Through an inductive study of four ventures working to deliver their promised products following successful crowdfunding ...

The role of external gas accretion on galaxy transformations, and evidence of such accretion [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractContinuously accreting matter from cosmic filaments is one of the main way to assemble mass for galaxies (Keres et al.2005, Dekel et al.2009). This external accretion accelerates secular processes, and maintain star formation, but also bar and spiral formation (Bournaud & Combes 2002), and consequent radial migration.

Predicting accreted satellite galaxy masses and accretion redshifts based on globular cluster orbits in the E-MOSAICS simulations [PDF]
The ages and metallicities of globular clusters (GCs) are known to be powerful tracers of the properties of their progenitor galaxies, enabling their use in determining the merger histories of galaxies.

Fueling Galaxy Growth Through Gas Accretion in Cosmological Simulations [PDF]
, 2015 Despite significant advances in the numerical modeling of galaxy formation and evolution, it is clear that a satisfactory theoretical picture of how galaxies acquire their baryons across cosmic time remains elusive.
