RIA Meeting: Physics opportunities with a new universe’s view: the SKA radio telescope

from to (Europe/Madrid)
at Universe ( Salon Actos )
The Square Kilometre Array (SKA) will be a multi-purpose radio-interferometer with a collecting area of 1 square kilometre, distributed over a distance of at least 3000 km, co-located in Africa and Australia. Qualified as landmark project in the European Strategy Forum on Research Infrastructures (ESFRI) and high-priority in the ASTRONET roadmaps, SKA is a unique science instrument, with up to 10 times more sensitivity, and hundred times faster survey capabilities than current radio- interferometers, that will provide leading edge science in the 21st century involving multiple science disciplines. The physics cases of this future multidisciplinary powerful telescope include Cosmology and Large Scale Structure, Epoch of Reionization (EoR), Galaxy evolution, Milky Way physics, Cosmic magnetism, Stellar Astrophysics and the Cradle of Life.

The high commitment from the Spanish community to SKA is clearly shown in the “Spanish SKA White Book”, published in 2015, which counted with the participation of 120 Spanish astronomers from 40 research centres. Nowadays 24 Spanish astrophysicists are members of 9 out of the 11 SKA Science Working Groups and more than 20 Spanish institutions and companies contribute to 7 out of 11 international SKA design consortia. A representative of MINECO is regularly invited to the SKA Board meetings since 2014. In 2016 a report was produced for the Evaluation of the participation of Spain in the SKA by the Secretary of State with a positive outcome. This has been followed by open and fluent negotiations with the SKA Organization, to find out the best way to join SKA as Full Member.

A call for Key Science Projects (KSP) will be issued by 2019. These KSPs will be using 50-75% of observation time during the first 5 years of SKA activity. Hence it is crucial that the Spanish scientific community actively participates in the preparation of proposals for KSPs by exploiting the fruitful synergies between SKA and its precursors (MeerKAT, ASKAP, MWA and HERA) and ongoing and future national and international astrophysical and cosmological observatories (E-ELT, ALMA, Chandra, MAGIC, CTA) and surveys (CALIFA, JPAS).

The major goal of this meeting is to maximize the interplay between the SKA Science and the Particle, Astroparticle, Planetary Sciences, Astrobiology and the Cosmology communities, going beyond radioastronomers and even astronomers.

      • 12:00 SKA and the Cradle of Life 30'
        In this talk I will provide a review of the current activities and future
        plans of the Cradle of Life working group. The deployment of the high
        frequency Band 5 receivers of the SKA will enable key science in the field
        of planet formation and Astrobiology. While the unprecedented high-angular
        resolution of SKA1-Mid will allow to image the thermal emission of
        centimetre-sized dust particles across the water snow line in nearby
        systems, its improved sensitivity with respect to current instrumentation
        will allow us to search for pre-biotic species such as formamide in
        proto-planetary disks and planet-sized fragments. On the other hand, the
        low frequency capabilities of SKA-Low can be used to study the magnetic
        fields of exolanets via their auroral synchrotron emission, which can
        provide information about their internal structure. These low frequency
        observations will also enable commensal SETI searches of technologically
        advanced signals down to levels of typical airport radars.

        Magnetic fields are observed on nearly all scales in the universe, from stars and galaxies upto galaxy clusters and even beyond. The origin of cosmic magnetic fields is still an open question, however a large class of models puts its origin in the very early universe. Observations of the CMB, LSS and 21 cm line can be used to constrain the magnetic field parameters.

      Convener: Dr. Aaron Vincent (IFIC)
      • 09:30 The Transient Universe with the Square Kilometer Array 30'
        The SKA as currently designed will be a ground-breaking facility for 
        radio transient studies.  I will give an overview of the possibilities for transient and variable-source astrophysics with the Square Kilometre Array.  I will focus on a few scientific topics that will highlight to aspects that may result in a dramatic increase of the scientific return: the addition of near-real-time commensal searches of data streams for events, and (ii) rapid robotic response to Target-of-Opprtunity like triggers

      Convener: Dr. Aaron Vincent
      • 10:00 The potential of SKA to detect the thermal emission of distant Solar System objects 30'
        The feasibility of SKA to measure the thermal emission of distant and cold Solar System objects, such as Trans-Neptunian objects (TNOs) and Centaurs, is investigated in terms of the different wavelengths and expected sensitivities. These thermal measurements would allow to obtain information, via thermal or thermophysical modeling, of sizes, albedos and thermal properties of TNOs and Centaurs. The results that can be obtained with SKA are complementary and extend those obtained by the Herschel Space Observatory within its observing key programme called 'TNOs are Cool: a survey of the transneptunian region' from which we derived sizes, albedos and thermal properties of 140 distant Solar System objects.

    • 11:30 - 12:00 Epoch of Reionization
      Convener: Dr. Sergio Palomares-Ruiz (IFIC/CSIC-UV)
      • 11:30 SKA and the Epoch of Reionization 30'
        Observations in the 21-cm line can probe different phases of
        reionization: an initial one where the atomic medium is cold and is seen in
        absorption at the highest redshifts, and the later signal of 21-cm emission
        from a heated medium before it is ionized. The emission signal is the easier
        one to observe in upcoming years, and it can arise from low-density regions
        that are less ionized than high-density ones, but also from high-density clumps
        that are more abundant in high-density regions, associated with sites of galaxy formation that can be observed also as damped Lyman alpha absorbers.
        Cross-correlation studies with other sources and emission lines will be
        essential to understand the origin of the 21-cm signal when it is detected.

      • 12:30 Weighing neutrinos with HI 30'
        I will show the impact of neutrino masses on the abundance and clustering properties of cosmic neutral hydrogen, that we have studied through high-resolution hydrodynamic simulations. I will point out that their effect can be understood taking into account the signatures neutrinos leave of halo properties. I will also present some forecasts showing that 21cm data from SKA can be used to place very competitive bounds on the sum of the neutrino masses.

        Pulsars have proven to be unique and powerful laboratories for studying fundamental physics.  In this talk, I will describe how SKA can deliver the next breakthroughs by discovering a large fraction of the Galactic pulsar population and thereby finding the ultimate `pulsar laboratories' for testing gravitational theories, probing the dense matter equation of state, and studying neutron star magnetospheres.
