Astronomia cultural: um olhar decolonial sobre e sob os céus do Brasil

open access: yesRevista Scientiarum Historia, 2019
Este trabalho traz uma reflexão sobre o estudo da Astronomia nas Culturas como uma forma de contribuição a um pensar decolonial sobre as formas de observar e interpretar o céu e os fenômenos astronômicos. Com o intuito de valorizar e dar visibilidade às epistemologias do Sul e como forma de contrariar a lógica dominante da episteme eurocêntrica ...

Archeointensity Database and Geomagnetic Field Reference Curves for South America Over the Past 5 Millennia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The study of variations in geomagnetic field intensity over time and space is crucial to understand the evolution of the geodynamo and its interactions with the Earth's surface. In this work, we introduce the SAGEOMAG (South America GEOMAGnetic) database, a comprehensive and updated repository of geomagnetic field intensity records derived ...

Take Me Home, Country Roads: Historical Diasporas and Contemporary FDI Patterns

open access: yesThe World Economy, Volume 49, Issue 1, Page 94-117, January 2026.
ABSTRACT We examine whether historical diasporas shape current foreign direct investment (FDI) flows, using Italian data from the ‘age of mass migration’ (1876–1925). We find that Italian regions with larger diasporas at the turn of the twentieth century maintain persistent economic ties with their historical destinations.

Quasi‐Constant Time Gap in Multiple Rings of Elves

open access: yesEarth and Space Science, Volume 12, Issue 10, October 2025.
Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...

Assessing the Reliability of the Pseudo‐Thellier Estimates in Fired Ceramics and Source Clays

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The geomagnetic field's intensity is key to understanding the Earth's core dynamics and their surface impacts. While the Thellier–Thellier method remains the standard for recovering absolute paleointensity from baked materials, it is time‐consuming and may alter magnetic mineralogy due to heating cycles. The pseudo‐Thellier method offers a non‐
