End of a Dark Age?

, 2016
We argue that dark matter and dark energy phenomena associated with galactic rotation curves, X-ray cluster mass profiles, and type Ia supernova data can be accounted for via small corrections to idealized general relativistic spacetime geometries due to

Water Vapor Vertical Distribution on Mars After Six Years of TGO/NOMAD Solar Occultations: 1. Global Climatology

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We present vertical profiles of water vapor obtained during six continuous years of solar occultation observations in the infrared by the Nadir and Occultation for MArs Discovery (NOMAD) instrument on board Trace Gas Orbiter. The retrievals have been performed with an inversion code previously applied to smaller samples of this data set, but ...

Temporal Changes in Europa's Ice Shell Thickness: Insights From Models of Convection

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Europa is characterized by a thin ice Ih shell overlying a subsurface ocean and a large solid core. Estimates of the outer ice shell's thickness range from a few kilometers to several tens of kilometers, with strong implications for Europa's thermal and geological history.

Cosmology with the Highly Redshifted 21cm Line [PDF]

, 2019
In addition to being a probe of Cosmic Dawn and Epoch of Reionization astrophysics, the 21cm line at $z>6$ is also a powerful way to constrain cosmology. Its power derives from several unique capabilities.

On the Possibility of Driving the Electron Flux Probabilistic Models by the AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We present the new probabilistic model of the electron fluxes designed to assess the risks of the spacecraft surface charging for missions with near‐equatorial orbits in the inner magnetosphere. It is a second model developed within a frame of the European Space Agency's activity “Plasma Environment Modeling in the Earth's Magnetosphere ...

Assessing Magnetic Fluctuations Effects in the South American Sector in Relation to Global Variations Using Ksa Index, Kp Index, and Hybrid Formats During Quiet Times Across the Seasons of the 2020 Solar Minimum

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Geomagnetic indices can be used to quantify variations in geomagnetic activity caused by Sun‐Earth interactions across the magnetosphere and ionosphere. The global Kp index is widely used as a global geomagnetic indicator, but it is based mostly on the Northern Hemisphere with no contributions from South American observatories.
