Observation of an Extraordinary Type V Solar Radio Burst: Nonlinear Evolution of the Electron Two-Stream Instability

Arnold O. Benz, Clemens R. Huber, Vincenzo Timmel +1

Solar type V radio bursts are associated with type III bursts. Several processes have been proposed to interpret the association, electron distribution, and emission. We present th…

Solar flares in the Solar Orbiter era: Short-exposure EUI/FSI observations of STIX flares

Hannah Collier, Laura A. Hayes, Stefan Purkhart +10

Aims: This paper aims to demonstrate the importance of short-exposure extreme ultraviolet (EUV) observations of solar flares in the study of particle acceleration, heating and ener…

Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data

M. Libralato, L. R. Bedin, M. Griggio +175

The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…

The observational evidence that all microflares that accelerate electrons to high energies are rooted in sunspots

Andrea Francesco Battaglia, Säm Krucker, Astrid M. Veronig +6

In general, large solar flares are more efficient at accelerating high-energy electrons than microflares. Nonetheless, we sometimes observe microflares that accelerate electrons to…

First joint X-ray solar microflare observations with NuSTAR and Solar Orbiter/STIX

Natália Bajnoková, Iain G. Hannah, Kristopher Cooper +5

We present the first joint spectral and imaging analysis of hard X-ray (HXR) emission from 3 microflares observed by the Nuclear Spectroscopic Telescope ARray (NuSTAR) and Solar Or…

High-Energy Insights from an Escaping Coronal Mass Ejection with Solar Orbiter/STIX Observations

Laura A. Hayes, Säm Krucker, Hannah Collier +1

Solar eruptive events, including solar flares and coronal mass ejections (CMEs), are typically characterised by energetically significant X-ray emissions from flare-accelerated ele…

Hard X-rays from the deep solar atmosphere. An unusual UV burst with flare properties

L. P. Chitta, I. G. Hannah, L. Fletcher +4

Explosive transient events occur throughout the solar atmosphere. The differing manifestations range from coronal mass ejections to Ellerman bombs. The former may have negligible s…

Calculated brightness temperatures of solar structures compared with ALMA and Metsähovi measurements

F. Matković, R. Brajša, M. Kuhar +6

The Atacama Large Millimeter/submillimeter Array (ALMA) allows for solar observations in the wavelength range of 0.310 mm, giving us a new view of the chromosphere. The measured…

Localising pulsations in the hard X-ray and microwave emission of an X-class flare

Hannah Collier, Laura A. Hayes, Sijie Yu +5

Aims: This work aims to identify the mechanism driving pulsations in hard X-ray (HXR) and microwave emission during solar flares. Here, by using combined HXR and microwave observat…

Energetic particle contamination in STIX during Solar Orbiter's passage through Earth's radiation belts and an interplanetary shock

Hannah Collier, Olivier Limousin, Hualin Xiao +8

The Spectrometer/Telescope for Imaging X-rays (STIX) is a hard X-ray imaging spectrometer on board the ESA and NASA heliospheric mission Solar Orbiter. STIX has been operational fo…
