Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

The Science of Gravitational-Wave Sources and Beyond Compact Binary Coalescences

open access: yes
This work focuses on the field of gravitational-wave astronomy by extending the scope of detectable sources beyond compact binary coalescences, All the gravitational-wave detections so far come from compact binary coalescences.

Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Geology of the central uplift of the Kamestastin Lake impact structure, Labrador, Canada

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The ~28 km Kamestastin (Mistastin) Lake impact structure is a relatively well‐preserved and well‐exposed complex impact structure. The central uplift of this structure is accessible as two islands in the middle of Kamestastin Lake. We present an updated, detailed geological map and description of Horseshoe and Bullseye islands that provides ...

The Demographic and Social Construction of Super‐Diversity

open access: yesPopulation and Development Review, EarlyView.
Abstract The concept of super‐diversity posits that waves of immigration over several decades expand population heterogeneity on multiple social, demographic, economic, political, and legal dimensions, creating a mosaic of social and cultural life in immigrant‐rich spaces.
