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.

  • Understanding AGN jets through the analysis of blazar multiwavelength variability

    Active galactic nuclei (AGN) are the most luminous persistent sources in the universe. A minority of AGN are characterised by powerful plasma jets extending from close to the supermassive black hole at the centre of their host galaxy up to megaparsec scales in the intergalactic space. Inside these jets, charged particles are accelerated to

  • JWST view of Polycyclic Aromatic Hydrocarbons and dust in local active galaxies

    Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN) in the interstellar medium (ISM) of the host galaxy has been proposed as a key mechanism responsible for regulating star formation (SF). The mid-infrared (IR) is the ideal spectral range to

  • Observing the polarized microwave sky: 10 years of the QUIJOTE experiment

    I will review the status of the QUIJOTE (Q-U-I JOint TEnerife) experiment, a project led from the IAC with the aim of characterising the polarisation of the Cosmic Microwave Background (CMB) and other galactic or extragalactic physical processes that emit in microwaves in the frequency range 10-42GHz, and at large angular scales (1 degree

  • NGC6240: Triple supermassive black holes in simulation and observation. Kozai-Lidov Effect and the timescale of PN merging.

    One of the possible ways of creating the supermassive black hole (SMBH) is hierarchical merging scenario. Central SMBHs at interacting and coalescing host-galaxies are observed as SMBH candidates at different separations from hundreds of pc to mpc. One of the strongest SMBHs candidates is ULIRG galaxy NGC6240 which was X-ray spatially and

  • The shady side of Stellar modelling and its grisly impact on Asteroseismology and Galactic Archeology

    Since the second half of last century, stellar evolution theory has allowed tounderstand the Color Magnitude Diagram of galactic star clusters, so that nowwe can explain the distribution of stars in the observed CMDs in terms of the nuclearevolution of stellar structures and, thus, in terms of cluster age and chemical composition.In the last

  • Pristine stars in the Milky-Way and beyond

    To understand the early phases of galaxy formation, metal-poor stars in the local universe play a special rôle, allowing to trace both how galactic assembly proceeds, and the conditions in which early star formation proceed. Metal-poor stars in our Galaxy and its satellites are fossils of these past processes and have therefore been the subject of

  • Why and How Gaia DR3 is revolutionizing Galactic Astronomy

    After placing the Gaia mission in the context of current astrophysical research, the astrometric, photometric, and spectroscopic data provided by the satellite, as presented in its third data archive, DR3, will be reviewed. Gaia third archive contains, in addition to the measurements from the satellite's instruments, an extensive set of

  • A tale of caution: the tails of open clusters are much longer than thought, but more difficult to find

    The tidal tails of stellar clusters are an important tool for studying the clusters’ birth conditions, their evolution, coupling, and interaction with the Galactic potential, and to understand how field stars populate the Milky Way. Thanks to Gaia, much progress has been accomplished in finding tails of open clusters. We will show here that the

  • The first Giga-years of the Milky Way halo and its satellites told by RRLs

    The first Gigayears of our Galactic halo can be probed by using ancient stellar populations as traced by RR Lyrae stars. Today, with the advancement in our knowledge of RR Lyrae properties belonging to the Halo and to Milky Way satellite systems (Globular clusters and dwarf galaxies) we are able to provide solid constraints on the link between

    Astrophysical observations at (sub)mm wavelengths (from ~300 micron to ~3mm) allow us to study the cold and dense material in the Universe, hence probing the formation of stars and planets, and the interstellar and circumgalactic medium within galaxies across cosmic time. The current generation of 15m-class single-dish telescopes has delivered some

    A rich phenomenology of jets, winds, and accretion states has been observed in both active galactic nuclei (AGN) and X-ray binaries (XRBs), suggesting a connection between the accretion and ejection flows at different black hole masses, from supermassive down to stellar mass.The X-ray emission, associated with the accretion flow, is strongly

    El uso de campos magnéticos no es habitual en la instrumentación desarrollada por el IAC. Sin embargo, en la actualidad dos proyectos hacen uso de los mismos con propósitos bien distintos.

  • (Almost) Thirty Years of the Sq-Polytropic Connection – An Overview on Some Basic Aspects of the Sq-based Therostatistics

    Almost thirty years ago, we pointed out that there is a connection between the Sq-non additive entropies, introduced by Tsallis in 1988, and the polytropic distributions in stellar dynamics. This was the first application of the Sq entropies to a concrete physical problem. The Sq-polytropic connection stimulated diverse developments in physics and
