A new class of white dwarfs, dubbed DAHe, that present Zeeman-split Balmer lines in emission has recently emerged. However, the physical origin of these...
Damped transverse oscillations of interacting coronal loops
Damped transverse oscillations of magnetic loops are routinely observed in the solar corona. This phenomenon is interpreted as standing kink magnetohydrodynamic...
Damping and Excitation Variations of the Solar Acoustic Modes Using LOWL Observations
We have used observations made with the helioseismic instrument LOWL collected over ~6 years to carry out an independent study of the variations of the p-mode...
Damping Mechanisms for Oscillations in Solar Prominences
Small amplitude oscillations are a commonly observed feature in prominences/filaments. These oscillations appear to be of local nature, are associated to the...
Damping of Fast Magnetohydrodynamic Oscillations in Quiescent Filament Threads
High-resolution observations provide evidence of the existence of small-amplitude transverse oscillations in solar filament fine structures. These oscillations...
Damping of prominence longitudinal oscillations due to mass accretion
We study the damping of longitudinal oscillations of a prominence thread caused by the mass accretion. We suggested a simple model describing this phenomenon...
Dark Energy Survey Deep Field photometric redshift performance and training incompleteness assessment
Context. The determination of accurate photometric redshifts (photo-zs) in large imaging galaxy surveys is key for cosmological studies. One of the most common...
Dark Energy Survey Y3 results: blending shear and redshift biases in image simulations
As the statistical power of galaxy weak lensing reaches per cent level precision, large, realistic, and robust simulations are required to calibrate...
