Magnetic Field Stratification in Active-Region Plage from Ca II K and Ca II 8542 Ã Spectropolarimetry
Iñigo Juanikorena Berasategi, Ernest Alsina Ballester, Javier Trujillo Bueno +31
The study measures how the line‑of‑sight magnetic field strength changes from the photosphere to the upper chromosphere in solar active‑region plage using Ca II K and Ca II 8542 Å…
Cataclysmic variables from SRG/eROSITA: new systems from eRASS1
A. D. Schwope, J. Brink, D. A. H. Buckley +12
The paper presents a new sample of 156 cataclysmic variable stars identified from the first eROSITA all‑sky X‑ray survey using a Random Forest classifier and follow‑up spectroscopy…
Angular Momentum Evolution from Core to Disk Scales in the Early Phase of Star Formation: Constraints from HH 212, HH 211, and B335
Chin-Fei Lee
The paper examines how specific angular momentum changes from large core scales down to disk scales in three young protostars, showing that an inside‑out collapse model with modest…
Merging galaxies and clusters: Insights into the role of magnetic fields and the physics of radio relics
Joseph Whittingham
The thesis uses high‑resolution cosmological magnetohydrodynamic simulations to study how magnetic fields evolve during galaxy mergers and how shock‑driven radio relics form in mer…
The topology of the magnetic field in Abell 2255 out to its virial radius. Results from the LOFAR Galaxy Cluster Ultra-Deep Field
A. Botteon, R. J. van Weeren, Y. Hu +14
The paper presents ultra‑deep LOFAR radio images of the galaxy cluster Abell 2255 and uses the synchrotron intensity gradient method to map the orientation of its magnetic field fr…
Mean-field interpretation of star-in-a-box simulations of red giants
Carolina A. Ortiz-RodrÃguez, Axel Brandenburg, Petri J. Käpylä
The paper uses mean‑field dynamo models, constrained by differential rotation profiles from global 3D simulations, to explain how magnetic fields are generated and evolve in red gi…
