An Extraordinary Dayside Negative Ionospheric Storm of 11 May 2024 and Total Electron Content (TEC) Vortices

On 10–11 May 2024, a major geomagnetic storm occurred on Earth. It significantly affected the dynamics of the Earth’s atmosphere and ionosphere. Here we report the occurrence of a severe dayside negative ionospheric storm in the American/Atlantic region during the recovery phase of the 10–11 May 2024 superstorm. The dayside total electron content (TEC) dropped by −90.05 TECU below the quiet‐time values, which represents extreme storm‐time deviations of ∼82%.

GLObal Solar Wind Structure (GLOWS)

Information on the evolution of latitudinal profiles of the solar wind speed and density is one of the important elements needed to understand global observations of heliospheric neutral and charged particle populations performed by NASA’s integrated heliospheric observatory Interstellar Mapping and Acceleration Probe (IMAP). This information is provided by the GLObal solar Wind Structure (GLOWS) experiment.

Theory and Modeling of Large Scale Plasmapause Surface Waves

The plasmapause in Earth’s magnetosphere represents the boundary between the plasma which co‐rotates with the Earth (plasmasphere), and the more tenuous plasmatrough outside. The density change across the plasmapause can be large, changing by approximately 1–2 orders of magnitude depending on the prevailing conditions.

Insights into environmental quenching at z ∼ 1: an enhancement of faint, low-mass passive galaxies in clusters

Understanding the processes that transform star-forming galaxies into quiescent ones is key to unravelling the role of environment in galaxy evolution.

The Spatial Distribution of Globular Cluster Systems in Early-type Galaxies: Estimation Procedure and Catalog of Properties for Globular Cluster Systems Observed with Deep Imaging Surveys

We present an analysis of the spatial distribution of globular cluster (GC) systems of 118 nearby early-type galaxies in the Next Generation Virgo Cluster Survey and Mass Assembly of early-Type GaLAxies with their fine Structures survey programs, which both used MegaCam on the Canada–France–Hawaii Telescope.

Driven Phase-mixed Alfvén Waves in a Partially Ionized Solar Plasma

Phase mixing has long been understood to be a viable mechanism for expediting the dissipation of Alfvén wave energy resulting in the subsequent heating of the solar atmosphere. To fulfill the conditions necessary for phase mixing to occur, we consider the cross-field gradient in the Alfvén speed as a free parameter in our model.

A Convolutional Neural Network for the Detection of Gravity Waves in Satellite Observations and Numerical Simulations

Comparisons between observed and model‐resolved gravity waves (GWs) are crucial for evaluating general circulation model (GCM) simulation accuracy and understanding wave characteristics. However, observational noise often obscures waves, complicating such comparisons. To address this, we have developed a GW detection method using a convolutional neural network (CNN).

Spatiotemporal Variations of Temperature in Jupiter’s Upper Atmosphere

Global temperatures in Jupiter’s upper atmosphere are poorly constrained. Other than an in situ measurement by the Galileo Probe, all temperature data come from remote-sensing methods that primarily rely on emissions from H 3+ , the dominant molecular ion in giant planet ionospheres.

Galaxy Zoo JWST: up to 75 per cent of discs are featureless at 3 < z < 7

We have not yet observed the epoch at which disc galaxies emerge in the Universe. While high-z measurements of large-scale features such as bars and spiral arms trace the evolution of disc galaxies, such methods cannot directly quantify featureless discs in the early Universe.
