Severo Ochoa Programme

Severo Ochoa Seminar

IAC Talks

Severo Ochoa Seminar program is an initiative that intends to increase visibility of the Incoming Severo Ochoa Senior Visitors program and to contribute to the professional training of the IAC PhD and postdoctoral personnel.
 
The lectures on the program aim to promote closer links between the different research groups at the IAC and those leaded by the visiting professors in their host institutions. The program is available to all interested researchers to participate, not only those involved directly into the SO project.

All Severo Ochoa visiting professors are encouraged to make a presentation related to the research focus of their collaborations.

 

  • 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

    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 to understand the Color Magnitude Diagram of galactic star clusters, so that now we can explain the distribution of stars in the observed CMDs in terms of the nuclear evolution of stellar structures and, thus, in terms of cluster age and chemical composition.

  • 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

  • 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 Atacama Large Aperture Submillimeter telescope (AtLAST) design study
    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

  • Disc-jet coupling in accreting systems
    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

    I discuss the dynamical interactions between the Milky Way and its satellite galaxies, focusing on the closest and most massive satellites - the Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy. The former just has had its first close encounter with the Milky Way very recently, and the latter has been orbiting our Galaxy for several
