Tracking a solar energetic eruption and associated energetic particles from Sun to spacecraft
D. E. Morosan, M. Baumgartner-Steinleitner, K. Bhandari +17

(abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs…
Ion acceleration in Fermi-LAT behind-the-limb solar flares: the role of coronal shock waves
Alexander Warmuth, Melissa Pesce-Rollins, Nicola Omodei +1
We investigate the relationship between the gamma-ray emission measured with Fermi-LAT and radio signatures of coronal shock waves in four behind-the-limb (BTL) solar flares. All e…
On the reason for the widespread energetic storm particle event of 13 March 2023
N. Dresing, I. C. Jebaraj, N. Wijsen +20
On 13 March 2023, when the Parker Solar Probe was situated on the far side of the Sun as seen from Earth, a large solar eruption took place creating a strong solar energetic partic…
Determining the acceleration regions of in situ electrons using remote radio and X-ray observations
D. E. Morosan, N. Dresing, C. Palmroos +13
Solar energetic particles in the heliosphere are produced by flaring processes on the Sun or shocks driven by coronal mass ejections. These particles are regularly detected remotel…
Solar energetic particles injected inside and outside a magnetic cloud: The widespread solar energetic particle event on 2022 January 20

Context. On 2022 January 20, the Energetic Particle Detector (EPD) on board Solar Orbiter measured a solar energetic particle (SEP) event showing unusual first arriving particles f…
Temperature and differential emission measure evolution of a limb flare on 13 January 2015
Malte Bröse, Alexander Warmuth, Taro Sakao +1
Spatially unresolved observations show that the cooling phase in solar flares can be much longer than theoretical models predict. It has not yet been determined whether this is als…
The existence of hot X-ray onsets in solar flares
Andrea Francesco Battaglia, Hugh Hudson, Alexander Warmuth +9
It is well known among the scientific community that solar flare activity often begins well before the main impulsive energy release. Our aim is to investigate the earliest phase o…
