The analysis of high spectral resolution spectroscopic and spectropolarimetric observations constitutes a very powerful way of inferring the dynamical...
Signatures of Magnetic Reconnection at the Footpoints of Fan-shaped Jets on a Light Bridge Driven by Photospheric Convective Motions
Dynamical jets are generally found on light bridges (LBs), which are key to studying sunspot decay. So far, their formation mechanism is not fully understood...
Signatures of the Galactic bar in high-order moments of proper motions measured by Gaia
Our location in the Milky Way provides an exceptional opportunity to gain insight on the galactic evolution processes, and complement the information inferred...
Signatures of the Galactic bar on stellar kinematics unveiled by APOGEE
Bars are common galactic structures in the local universe that play an important role in the secular evolution of galaxies, including the Milky Way. In...
Signatures of the impact of flare-ejected plasma on the photosphere of a sunspot light bridge
Aims: We investigate the properties of a sunspot light bridge, focusing on the changes produced by the impact of a plasma blob ejected from a C-class flare...
Simulating galactic outflows with kinetic supernova feedback
Feedback from star formation is thought to play a key role in the formation and evolution of galaxies, but its implementation in cosmological simulations is...
Simulating galactic outflows with thermal supernova feedback
Cosmological simulations make use of sub-grid recipes for the implementation of galactic winds driven by massive stars because direct injection of supernova...
Single stellar populations in the near-infrared. I. Preparation of the IRTF spectral stellar library
We present a detailed study of the stars of the NASA InfraRed Telescope Facility (IRTF) spectral library to understand its full extent and reliability for use...
Small-scale magnetic flux emergence preceding a chain of energetic solar atmospheric events
Context. Advancements in instrumentation have revealed a multitude of small-scale extreme-ultraviolet (EUV) events in the solar atmosphere and considerable...
