A method for ``time/frequency'' analysis is shortly described, with a discussion of its limitations in time and frequency resolution, and in sensitivity to...
Temporal evolution of arch filaments as seen in He I 10 830 Å
Aims: We study the evolution of an arch filament system (AFS) and of its individual arch filaments to learn about the processes occurring in them. Methods: We...
Temporal evolution of small-scale internetwork magnetic fields in the solar photosphere
Context. While the longitudinal field that dominates in photospheric network regions has been studied extensively, small-scale transverse fields have recently...
Temporal evolution of the Evershed flow in sunspots. I. Observational characterization of Evershed clouds
Context: The magnetic and kinematic properties of the photospheric Evershed flow are relatively well known, but not completely understood. The evolution of the...
Temporal relation between quiet-Sun transverse fields and the strong flows detected by IMaX/SUNRISE
Context. Localized strongly Doppler-shifted Stokes V signals were detected by IMaX/SUNRISE. These signals are related to newly emerged magnetic loops that are...
Temporal variation of the photometric magnetic activity for the Sun and Kepler solar-like stars
Context. The photometric time series of solar-like stars can exhibit rotational modulation, that is, brightness variations due to active regions co-rotating...
Tensor-to-scalar ratio forecasts for extended LiteBIRD frequency configurations
LiteBIRD is a planned JAXA-led cosmic microwave background (CMB) B-mode satellite experiment aiming for launch in the late 2020s, with a primary goal of...
Teraelectronvolt pulsed emission from the Crab Pulsar detected by MAGIC
Aims: We investigate the extension of the very high-energy spectral tail of the Crab Pulsar at energies above 400 GeV. Methods: We analyzed ~320 h of good...
