Identifying the energy release site in a Solar microflare with a jet
Andrea Francesco Battaglia, Wen Wang, Jonas Saqri +10
One of the main science questions of the Solar Orbiter and Parker Solar Probe missions deals with understanding how electrons in the lower solar corona are accelerated and how they…
Flares detected in ALMA single-dish images of the Sun
I. Skokić, A. O. Benz, R. Brajša +3
The (sub)millimeter radiation of solar flares is poorly understood. Without spatial resolution, it cannot be compared easily to flare emissions in other wavelengths. The Atacama La…
Multiple Regions of Nonthermal Quasi-Periodic Pulsations during the Impulsive Phase of a Solar Flare
Yingjie Luo, Bin Chen, Sijie Yu +2
Flare-associated quasiperiodic pulsations (QPPs) in radio and X-ray wavelengths, particularly those related to nonthermal electrons, contain important information about the energy…
Preparing for Solar and Heliospheric Science with the SKAO: An Indian Perspective
Divya Oberoi, Susanta Kumar Bisoi, K. Sasikumar Raja +4
The Square Kilometre Array Observatory (SKAO) is perhaps the most ambitious radio telescope envisaged yet. It will enable unprecedented studies of the Sun, the corona and the helio…
The interplay of local electron correlations and ultrafast spin dynamics in fcc Ni
Tobias Lojewski, Mohamed F. Elhanoty, Loïc Le Guyader +48
The complex electronic structure of metallic ferromagnets is determined by a balance between exchange interaction, electron hopping leading to band formation, and local Coulomb rep…
The First Survey of Quiet Sun Features Observed in Hard X-Rays With NuSTAR
Sarah Paterson, Iain G. Hannah, Brian W. Grefenstette +5
We present the first survey of quiet Sun features observed in hard X-rays (HXRs), using the the Nuclear Spectroscopic Telescope ARray (NuSTAR), a HXR focusing optics telescope. The…
Euclid preparation. XXV. The Euclid Morphology Challenge -- Towards model-fitting photometry for billions of galaxies
Euclid Collaboration, E. Merlin, M. Castellano +218
The ESA Euclid mission will provide high-quality imaging for about 1.5 billion galaxies. A software pipeline to automatically process and analyse such a huge amount of data in real…
Euclid preparation: XXII. Selection of Quiescent Galaxies from Mock Photometry using Machine Learning
Euclid Collaboration, A. Humphrey, L. Bisigello +206
The Euclid Space Telescope will provide deep imaging at optical and near-infrared wavelengths, along with slitless near-infrared spectroscopy, across ~15,000 sq deg of the sky. Euc…
Detection of weak ubiquitous impulsive nonthermal emissions from the solar corona
Rohit Sharma, Divya Oberoi, Marina Battaglia +1
A ubiquitous presence of weak energy releases is one of the most promising hypotheses to explain coronal heating, referred to as the nanoflare hypothesis. The accelerated electrons…
The Lyman- Emission in a C1.4 Solar Flare Observed by the Extreme Ultraviolet Imager aboard Solar Orbiter
Ying Li, Qiao Li, De-Chao Song +7
The hydrogen Lyman- (H {\sc i} Ly) emission during solar flares has rarely been studied in spatially resolved images and its physical origin has not been fully understood. In…
Observations of Thomson scattering from a loop-prominence system
Juan Carlos Martínez Oliveros, Juan Camilo Guevara Gómez, Pascal Saint-Hilaire +2
We describe observations of the white-light structures in the low corona following the X8.2 flare SOL2017-09-10, as observed in full Stokes parameters by the Helioseismic and Magne…
Spatial distribution of jets in solar active regions
Jonas Odermatt, Krzysztof Barczynski, Louise K. Harra +2
Context. Solar active regions are known to have jets. These jets are associated with heating and the release of particles into the solar wind. Aim. Our aim is to understand the spa…
The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter
Laura A. Hayes, Sophie Musset, Daniel M üller +1
The Spectrometer/Telescope for Imaging X-rays (STIX) is one of the 10 instruments on-board the scientific payload of ESA's Solar Orbiter mission. STIX provides hard X-ray imaging s…
The Astropy Project: Sustaining and Growing a Community-oriented Open-source Project and the Latest Major Release (v5.0) of the Core Package
The Astropy Collaboration, Adrian M. Price-Whelan, Pey Lian Lim +133
The Astropy Project supports and fosters the development of open-source and openly-developed Python packages that provide commonly needed functionality to the astronomical communit…
