The Inka Khipu and Yupana: A Reply to Zen Vasconcellos and Rojas Gamarra (2026)

Astronomische Nachrichten, EarlyView.
ABSTRACT A new analysis by Zen Vasconcellos and Rojas Gamarra offers a novel interpretation of the Inka devices used for calculating (yupana) and recording (khipu) numbers. They claim the Inka devices represented numbers neither positionally, with place value, as most researchers have assumed, nor additively, without place value, a possibility uniquely

The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry

Astronomische Nachrichten, EarlyView.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019.

Neutrino Oscillation in a Minimal Length Spacetime

Astronomische Nachrichten, EarlyView.
ABSTRACT We investigate how neutrino oscillations are modified in a non‐commutative spacetime characterized by a minimal length scale, described by the Quesne–Tkachuk algebra. By incorporating the algebra's deformation parameter β$$ \beta $$ into the effective neutrino mass, we derive the two‐flavor oscillation probability in this non‐commutative ...

EBHIS Local Volume Galaxy Hi Survey (LVGHIS)

Astronomische Nachrichten, EarlyView.
ABSTRACT Here, we present the “Local Volume Galaxy Hi Survey” (LVGHIS). It is based on the first data release of the Milky Way portion of the Effelsberg Bonn Hi‐Survey (EBHIS). We homogeneously measured the mass and dynamics of the local volume galaxies within the radial velocity limit of |vLSR|≤600kms−1$$ \mid {v}_{\mathrm{LSR}}\mid \le 600\kern0.6em \

The absence of women's scientific contributions in core UK pre‐university science qualifications

British Educational Research Journal, EarlyView.
Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...
