New scaling factors are presented describing the altitude and latitudinal dependence of
production rates for in situ produced cosmogenic nuclides. The new factors incorporate the …

A review of 16 lake sediment paleomagnetic records from western North America, spanning
time intervals over the last 40 000 yr BP, provides evidence that many of these lacustrine …

Polarity reversals of the geomagnetic field have occurred through billions of years of Earth
history and were first revealed in the early 20th century. Almost a century later, details of …

Earth's magnetic field is unstable. Not only does it vary in intensity, but from time to time it
flips, with the poles reversing sign. Much of this behaviour remains a mystery, but a …

We present palaeomagnetic and cosmogenic radionuclide records of the Laschamp
geomagnetic excursion in Lake Pupuke, a maar lake in Auckland, New Zealand. Laschamp …

Large scale magnetic fields represent a triple point where cosmology, high-energy physics
and astrophysics meet for different but related purposes. After reviewing the implications of …

The period some 20–25 kyr just prior to the most recent generally recognized geomagnetic
field polarity transition, the Matuyama-to-Brunhes reversal, appears to be marked by …

As new seafloor is created at the ridge crest, it cools and acquires a thermoremanence that
captures a record of past geomagnetic field variations. The dominant geomagnetic signal …

Geomagnetic field reversal is a rapid phenomenon1, 2, perhaps taking only a few thousand
years. Knowledge of how the field behaves during these brief and active periods may …

We study primordial magnetic field effects on the matter perturbations in the universe. We
assume magnetic field generation prior to the big bang nucleosynthesis (BBN), ie, during the …
