The universality of the stellar initial mass function (IMF) is one of the most widespread assumptions in modern Astronomy and yet, it might be flawed. While observations in the Milky Way generally support an IMF that is invariant with respect to the local conditions under which stars form, measurements of massive early-type galaxies systematically point towards a non-universal IMF. To bridge the gap between both sets of evidence, in this work we measured for the first time the low-mass end of the IMF from the integrated spectra of a Milky Way-like galaxy, NGC3351. We found that the slope of

Understanding the magnetic field in the corona is key for explaining the fascinating physical processes occurring there. However, the extreme conditions in the outer solar atmosphere hamper the possibility of acquiring observations with enough quality to infer the coronal magnetic field. Analyzing observations of overdensities of cold plasma supported by coronal magnetic fields, including filaments and prominences, allows us to understand such magnetic fields and their interaction with plasma. In this study, we have analyzed an active region prominence, a type of prominence that has barely

Asteroids are the remnants of the planetary formation in the Solar System and so, their study helps us to understand the conditions during the early stages of the formation of our planetary system. Among asteroids, those classified as primitives present similar spectra to that of carbonaceous chondrites, i.e., they are rich in carbon and organic compounds and silicates altered by the presence of liquid water (phyllosilicates). Primitive asteroids are well characterized in various wavelength regions, showing their most diagnostic feature at 3μm. However, there is a lack of information in the
