Line formation of He I D3 and He I 10830 Å in a small-scale reconnection event
T. Libbrecht, J. P. Bjørgen, J. Leenaarts +3
Aims. We aim to explain line formation of He I D3 and He I 10830 Å in small-scale reconnection events. Methods. We make use of a simulated Ellerman bomb (EB), present in a Bifrost-…
Three-dimensional magnetic field structure of a flux emerging region in the solar atmosphere
Rahul Yadav, J. de la Cruz Rodríguez, C. J. Díaz Baso +4
We analyze high-resolution spectropolarimetric observations of a flux emerging region (FER) in order to understand its magnetic and kinematic structure. Our spectropolarimetric obs…
Dissecting bombs and bursts: non-LTE inversions of low-atmosphere reconnection in SST and IRIS observations
G. J. M. Vissers, J. de la Cruz Rodriguez, T. Libbrecht +3
Ellerman bombs and UV bursts are transient brightenings that are ubiquitously observed in the lower atmospheres of active and emerging flux regions. Here we present inversion resul…
Chromospheric condensations and magnetic field in a C3.6-class flare studied via He I D3 spectro-polarimetry
Tine Libbrecht, Jaime de la Cruz Rodriguez, Sanja Danilovic +2
Context. Magnetic reconnection during flares takes place in the corona but a substantial part of flare energy is deposited in the chromosphere. However, high-resolution spectro-pol…
Observations of Ellerman bomb emission features in He I D3 and He I 10830 Å
Tine Libbrecht, Jayant Joshi, Jaime de la Cruz Rodríguez +2
Context. Ellerman bombs (EBs) are short-lived emission features, characterized by extended wing emission in hydrogen Balmer lines. Until now, no distinct signature of EBs has been…
The cause of spatial structure in solar He I 1083 nm multiplet images
Jorrit Leenaarts, Thomas Golding, Mats Carlsson +2
Context. The He i 1083 nm is a powerful diagnostic for inferring properties of the upper solar chromosphere, in particular for the magnetic field. The basic formation of the line i…
The high-redshift gamma-ray burst GRB140515A
A. Melandri, M. G. Bernardini, P. D'Avanzo +22
High-redshift gamma-ray bursts have several advantages for the study of the distant universe, providing unique information about the structure and properties of the galaxies in whi…
