Star clusters as age tracers of the age-metallicity relation of the small magellanic cloud [PDF]

, 2009
In my Thesis, I determined ages of Small Magellanic Cloud (SMC) star clusters that have formed during the galaxys entire lifetime.

A MARVEL-ous Study of How Well Galaxy Shapes Reflect Dark Matter Halo Shapes in Cold Dark Matter Simulations

The Astrophysical Journal
We present a 3D shape analysis of both dark matter (DM) and stellar matter (SM) in simulated dwarf galaxies to determine whether stellar shape traces DM shape. Using 80 central and satellite dwarf galaxies from three simulation suites (“Marvelous Massive

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

The formation of ultra-compact dwarf galaxies and nucleated dwarf galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
Ultra-compact dwarf galaxies (UCDs) have similar properties as massive globular clusters or the nuclei of nucleated galaxies. Recent observations suggesting a high dark matter content and a steep spatial distribution within groups and clusters provide new clues as to their origins.

Black holes in the low-mass galaxy regime

Astronomy & Astrophysics
Context. Active galactic nuclei (AGNs) have been observed in dwarf galaxies, yet the impact of black hole feedback in these low-mass systems remains unclear. Aims.

The effect of simulated intergroup encounters on movement patterns and home range use in banded mongooses

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Intergroup conflicts have a wide range of impacts, including affecting movement and ranging patterns. Previous studies found contrasting movement responses to intergroup conflicts, but no explanation for these differences has been suggested. However, these can be broadly grouped into ‘conflict avoidance' responses: avoiding areas close to the fight ...

Hunting strategies, success, and sustainability: A case study in a community forest on the edge of Salonga National Park, DRC

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
In Central Africa, traditional hunting is central to the way of life of local communities. However, increasing demand for wild meat has raised concerns about the sustainability of this practice. With a year‐long analysis of hunting strategies and their impact at the outskirts of Salonga National Park, Democratic Republic of the Congo, we showed a ...

Early assembly of the most massive galaxies [PDF]

, 2009
The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging(1).

The Formation of Dwarf Galaxy Disks

The Astrophysical Journal
Dwarf galaxies are dark matter-dominated systems that are sensitive to feedback and display a diversity of baryonic morphologies. This makes them excellent probes for understanding dark matter and galaxy evolution.

HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186

The Astrophysical Journal, 2023
Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representative of the low-mass star-forming galaxies that are thought to play a ...
