A Cell Biologist’s Field Guide to Aurora Kinase Inhibitors

Frontiers in Oncology, 2015
Aurora kinases are essential for cell division and are frequently misregulated in human cancers. Based on their potential as cancer therapeutics, a plethora of small molecule Aurora kinase inhibitors have been developed, with a subset having been adopted

Development of low-cost multi-wavelength imager system for studies of aurora and airglow [PDF]

, 2020
This paper introduces a new system that can monitor aurora and atmospheric airglow using a low-cost Watec monochromatic imager (WMI) equipped with a sensitive camera, a filter with high transmittance, and the non-telecentric optics.

Auroral Drivers of Large dB∕dt During Geomagnetic Storms

Space Weather, 2022
Forecasting geomagnetically induced currents (GICs) remains a difficult challenge, and open questions hindering our understanding include when and where GICs become large and what magnetospheric and ionospheric processes are responsible.

Observations of 4.26 μm CO2 Auroral Emissions From AIRS Nadir Sounder Measurements

Geophysical Research Letters, 2023
The Atmospheric Infrared Sounder (AIRS) instrument onboard the NASA Aqua satellite is used to observe aurora associated with the CO2 4.26 μm emission. These observations are due to non‐local thermodynamic equilibrium (NLTE) resulting from the vibrational

Discrete Aurora at Mars: Insights Into the Role of Magnetic Reconnection

Geophysical Research Letters, 2023
Discrete aurora are sporadic emissions of light originating in Mars upper atmosphere. We report nadir imaging observations from MAVEN's Imaging UltraViolet Spectrograph which identify the conditions which trigger electron precipitation causing these ...

Are Dawn Storms Jupiter's Auroral Substorms?

AGU Advances, 2021
Dawn storms are among the brightest events in the Jovian aurorae. Up to now, they had only been observed from Earth‐based observatories, only showing the Sun‐facing side of the planet. Here, we show for the first time global views of the phenomenon, from

The polarisation of auroral emissions: A tracer of the E region ionospheric currents

Journal of Space Weather and Space Climate, 2022
It is now established that auroral emissions as measured from the ground are polarised. The question of the information given by this polarisation is still to be explored.

Flow Shears at the Poleward Boundary of Omega Bands Observed During Conjunctions of Swarm and THEMIS ASI

Geophysical Research Letters, 2018
Omega bands are curved aurora forms that evolve from a quiet arc located along the poleward edge of a diffuse auroral band within the midnight to morningside auroral oval. They usually propagate eastward. Because omega bands are a significant contributor
