The date and context of the Astronomer's Life of Louis the Pious

Early Medieval Europe, Volume 34, Issue 1, Page 70-100, February 2026.
The Astronomer's Life of the emperor Louis the Pious (814–40) is a canonical source for scholars of Frankish history. It sits at the centre of recent debates about the nature and tone of Carolingian political discourse, and about the crisis of the empire in the 830s.

Evaluating Investment in Space Programs: A Case for Theoretical Pluralism

Financial Accountability &Management, Volume 42, Issue 1, Page 19-35, February 2026.
ABSTRACT A perennial question repeatedly asked since the early Mercury (USA) and Salyut (then Soviet Union) space programs has been variations on the theme of “how can the cost of space exploration be justified?” This question—which in broad terms constitutes the research question considered in this paper—continues to be directed toward space agencies ...

Estimating Soil Electrical Parameters in the Canadian High Arctic From Impedance Measurements of the MIST Antenna Above the Surface

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The MIST experiment aims to detect the cosmological 21‐cm signal through sky observations at 25–125 MHz using a wide‐beam antenna. The antenna is mounted above the soil and the beam characteristics are highly dependent on the soil's electrical properties.
