Mulberry Affects:Ecology, Memory, and Aesthetics on the Shores of the Tigris River in the Wake of Genocide

How can the Armenian genocide be considered in terms of its ecological roots and remnants? Umut Yıldırım explores the more-than-human flora and fauna indigenous to the banks of the Tigris river in Upper Mesopotamia — in particular, centenarian mulberry trees — as resistant roots that register the evidentiary ecologies of the Armenian genocide through the Turkish state’s denialist present and its ongoing war against the Kurds.Umut Yıldırım, ‘Mulberry Affects: Ecology, Memory, and Aesthetics on the Shores of the Tigris River in the Wake of Genocide’, in War-torn Ecologies, An-Archic Fragments: Reflections from the Middle East, ed. by Umut Yıldırım, Cultural Inquiry, 27 (Berlin: ICI Berlin Press, 2023), pp. 27-66 <https://doi.org/10.37050/ci-27_2

The structural and dynamical properties of compact elliptical galaxies

Dedicated photometric and spectroscopic surveys have provided unambiguous evidence for a strong stellar mass-size evolution of galaxies within the last 10 Gyr. The likely progenitors of today's most massive galaxies are remarkably small, disky, passive and have already assembled much of their stellar mass at redshift z=2. An in-depth analysis of these objects, however, is currently not feasible due to the lack of high-quality, spatially-resolved photometric and spectroscopic data. In this paper, we present a sample of nearby compact elliptical galaxies (CEGs), which bear resemblance to the massive and quiescent galaxy population at earlier times. Hubble Space Telescope (HST) and wide-field integral field unit (IFU) data have been obtained, and are used to constrain orbit-based dynamical models and stellar population synthesis (SPS) fits, to unravel their structural and dynamical properties. We first show that our galaxies are outliers in the present-day stellar mass-size relation. They are, however, consistent with the mass-size relation of compact, massive and quiescent galaxies at redshift z=2. The compact sizes of our nearby galaxies imply high central stellar mass surface densities, which are also in agreement with the massive galaxy population at higher redshift, hinting at strong dissipational processes during their formation. Corroborating evidence for a largely passive evolution within the last 10 Gyr is provided by their orbital distribution as well as their stellar populations, which are difficult to reconcile with a very active (major) merging history. This all supports that we can use nearby CEGs as local analogues of the high-redshift, massive and quiescent galaxy population, thus providing additional constraints for models of galaxy formation and evolution.Comment: 33 pages, 27 figures and 20 tables (with most of the tables provided as online-only supporting information).
