Programa Severo Ochoa

Seminario Severo Ochoa

IAC Talks

El Programa de Seminarios Severo Ochoa es una iniciativa encaminada a aumentar la visibilidad del programa de Visitantes Senior Severo Ochoa recibidos en el IAC y contribuir a la formación profesional del personal predoctoral y postdoctoral del IAC.

Las conferencias previstas en el programa tratan de fomentar la colaboración entre los diferentes grupos de investigación del IAC y los liderados por los profesores visitantes en sus propias instituciones. El programa está abierto a la participación de todos los investigadores interesados, no sólo de los vinculados directamente al proyecto SO.

Se anima a todos los profesores visitantes Severo Ochoa a presentar el tema de investigación objeto de sus colaboraciones.

  • The formation of Milky Way-mass galactic disc structure in cosmological simulations
    Recent years have seen impressive development in cosmological simulations for spiral disc galaxies like the Milky Way. I present a suite of high-resolution magneto-hydrodynamic simulations that include many physical processes relevant for galaxy formation, including star formation, stellar evolution and feedback, active galactic nuclei and magnetic

  • Magnetic Flux, Heating, & Flaring: Clues from the Sun for Other Stars & Systems
    On the Sun, the presence of magnetic flux at the photosphere is closely linked to (1) steady heating of the overlying atmosphere and (2) transient brightenings, the largest of which are flares. I will discuss statistical properties of both phenomena, with an emphasis on aspects of each that might apply to other astrophysical objects, such as other

  • Dynamos, the drivers of solar and stellar activity
    Following Cowling's anti-dynamo theorem of 1933, there was a long period during which the very existence of dynamos was unclear. Even with the emergence of three dimensional simulations in the late 1980s, people were careful to distinguish true dynamos from just some sort of amplification. Meanwhile, we know of many examples of true dynamos - not

  • Galactic Globular Clusters: Why should we care about them?
    Galactic globular clusters have always been at the crossroad of several investigations in both Stellar and Galactic Astrophysics. For long time, they have been considered the prototypes of Simple Stellar Populations, and hence used for testing and calibrating stellar evolutionary models as well as population synthesis tools. Nowadays, after the

  • PLANETARY PIECES: PUTING THE CLUES TOGETHER USING WHITE DWARFS
    Planetary systems have been found systematically orbiting main sequence stars and red giants. But the detection of planets per se during the white dwarf phase has been more elusive with only 3 systems. We have, however, ample indirect evidence of the existence of planetary debris around these systems in the form of material acreted onto the white

  • Magnetic reconnection in partially ionized plasmas
    The phenomenon of magnetic reconnection in a magnetized plasma has been a subject of numerous studies over the past several decades in a variety of contexts, from high energy astrophysics, to solar and space physics, to laboratory-based experiments. However, most magnetic reconnection studies have been devoted to exploring different collisionality

  • Using the Visible Spectral Reflectance Properties to Probe Aqueous Alteration in the Solar System
    During the past 50 years, we have witnessed humankind’s first good, detailed look at the planets in our known Solar System. All of these advances built upon Earth-based telescopic observations. We predict surface conditions on other Solar System bodies before spacecraft reach them for in situ study. The dominant type of asteroid identified

  • The interplay between local and global properties in galaxies
    We summarize here some of the results reviewed recently by Sanchez (2020) and Sanchez et al. (2021), comprising the advances in the comprehension of galaxies in the nearby universe based on integral field spectroscopic galaxy surveys. We review our current knowledge of the spatially resolved spectroscopic properties of low-redshift star-forming

  • The rotation of massive stars with and without compact companions
    Massive stars are generally fast rotators, however, with significant dispersion. We discuss the hypothesis that all OB stars are all born with very similar spins, with slower and faster rotators being produced by close binary evolution. We review supporting evidence from recent observations of young and rich star clusters, from OB star surveys, and

  • Using Machine learning in interstellar medium
    Artificial intelligence techniques are increasingly used in our daily lives. They also play an important role in science, including astrophysics. I am particularly interested in the use of machine learning regressors. I will present an overview of the current situation and some recent uses of these methods in the study of planetary nebulae or HII

  • Reconstructing the history of the Milky Way and probing the dark matter nature in WEAVE and LSST era
    At present, our understanding of the formation history of the MW is limited due to the complexity of observing the imprints of accretion events and of reproducing them in numerical simulations. Moreover, though being the only galaxy, in which the Galactic potential can be probed in detail, the distribution of mass in the MW, and hence of the dark

  • Constraints on Ultra-Light Dark Matter from Galactic Rotation Curves
    Bosonic ultra-light dark matter (ULDM) in the mass range m ~ $10^{-22} - 10^{-21} \rm eV$ has been invoked as a motivated candidate with new input for the small-scale `puzzles' of cold dark matter. Numerical simulations show that these models form cored density distributions at the center of galaxies ('solitons'). These works also found an

  • The evolutionary history of the Milky Way disk(s) and halo from Gaia colour-magnitude diagram fitting
    Gaia has provided distances and photometry, and thus colour-magnitude diagrams in the absolute plane, for stars over a large volume in the Milky Way, encompassing significant fractions of the thin and thick disk, and halo. This has allowed us, for the first time, to derive unprecedentedly detailed star formation histories from direct modelling of
