Dark Matter Halo Merger Trees
<p>This dataset is generated from the Genesis suite of dark matter only N-body simulations (C. Power et al in prep). L10_N2048 is a periodic cubical simulation of side 10 h^-1 Mpc, with 2048^3 particles each of mass 1.0e4 h^-1 solar units. It is used as the initial condition for models presented in <a href="https://ui.adsabs.harvard.edu/abs/2024arXiv240107396V" target="_blank" rel="noopener">E. M. Ventura et al. (2024)</a> S. Balu, along with input from C. Power ran the simulation using the SWIFT (<a href="https://ui.adsabs.harvard.edu/abs/2023arXiv230513380S" target="_blank" rel="noopener">Schaller et al. 2023</a>) cosmological code, identified haloes using the six-dimensional phase-space halo-finder VELOCIraptor (<a href="https://ui.adsabs.harvard.edu/abs/2019ascl.soft11020E" target="_blank" rel="noopener">Elahi et al. 2019a</a>), and constructed the merger trees with TREEFROG (<a href="https://ui.adsabs.harvard.edu/abs/2019ascl.soft11021E" target="_blank" rel="noopener">Elahi et al. 2019b</a>). During the halo-finding, Friends-of-Friends group require a minimum of 32 particles and the subhaloes need atleast 20 particles. S. Balu converted the original files into the format required by <a href="https://github.com/meraxes-devs/meraxes" target="_blank" rel="noopener">Meraxes</a> using codes developed by S.

Jenseits des Endes: Die Stille als Erzählerin der Postapokalypse in "The Long Dark" (Videoessay)
<p>Dieser Videoessay (im Rhamen der Interdisziplinären Tagung "Game Over? – Dystopia x Utopia x Video Games" an der Paris Lodron Universität Salzburg, 14. bis 16. November 2024 an der Paris Lodron Universität Salzburg) untersucht, wie das Survival-Spiel "The Long Dark" durch den radikalen Einsatz von Stille die konventionellen Darstellungsmuster postapokalyptischer Narrative durchbricht. Anhand einer dreifachen Analyse - atmosphärische Dämpfung, strukturelle Abwesenheit und narrative Sparsamkeit - wird gezeigt, wie das Spiel etablierte Genre-Konventionen unterläuft. Der Essay argumentiert, dass gerade in der konsequenten Reduktion eine neue Perspektive auf postapokalyptische Szenarien emergiert. Dabei wird die Stille nicht als passive Abwesenheit, sondern als aktives gestalterisches Prinzip begriffen. Die Analyse verbindet medientheoretische Konzepte mit game-studies-spezifischen Betrachtungen und öffnet so den Blick für alternative Formen des postapokalyptischen Erzählens im Medium Videospiel.</p> <p>-------</p> <p>Music by <a title="https://pixabay.com/users/ambientaudiovision-25188255/?utm_source=link-attribution&utm_medium=referral&utm_campaign=music&utm_content=194926" href="https://pixabay.com/users/ambientaudiovision-25188255/?utm_source=link-attribution&utm_medium=referral&utm_campaign=music&utm_content=194926">Amir Firouzfard</a> from <a title="https://pixabay.com//?utm_source=link-attribution&utm_medium=referral&utm_campaign=music&utm_content=194926" href="https://pixabay.com//?utm_source=link-attribution&utm_medium=referral&utm_campaign=music&utm_content=194926">Pixabay</a></p>

Color, activity period, and eye structure in four lineages of ants: Pale, nocturnal species have evolved larger eyes and larger facets than their dark, diurnal congeners
<p>The eyes of insects display an incredible diversity of adaptations to enhance vision across the gamut of light levels they experience. One commonly studied contrast is the difference in eye structure between nocturnal and diurnal species, with nocturnal species typically having features that enhance eye sensitivity such as larger eyes, larger eye facets, and larger ocelli. In this study, we compared eye structure between workers of closely related nocturnal and diurnal above-ground foraging ant species (Hymenoptera: Formicidae) in four genera (<em>Myrmecocystus, Aphaenogaster, Temnothorax, Veromessor</em>). In all four genera, nocturnal species tend to have little cuticular pigment (pale), while diurnal species are heavily pigmented (dark), hence we could use cuticle coloration as a surrogate for activity pattern. Across three genera (<em>Myrmecocystus, Aphaenogaster, Temnothorax</em>), pale species, as expected for nocturnally active animals, had larger eyes, larger facet diameters, and larger visual spans compared to their dark, more day-active congeners. This same pattern occurred for one pale species of <em>Veromessor</em>, but not the other. There were no consistent differences between nocturnal and diurnal species in interommatidial angles and eye parameters both within and among genera. Hence, the evolution of eye features that enhance sensitivity in low light levels do not appear to have consistent correlated effects on features related to visual acuity. A survey across several additional ant genera found numerous other pale species with enlarged eyes, suggesting these traits evolved multiple times within and across genera. We also compared the size of the anterior ocellus in workers of pale versus dark species of <em>Myrmecocystus</em>. In species with larger workers, the anterior ocellus was smaller in pale than in dark species, but this difference mostly disappeared for species with smaller workers. Presence of the anterior ocellus also was size-dependent in the two largest pale species.</p>
