    Interstellar objects and their potential role in planet formation

     

    The formation and evolution of planetary systems commonly leads to the ejection of predominantly icy objects. The expectation, therefore, is that the Galaxy has a background population of interstellar planetesimals ejected from these systems. We argue that 1I/‘Oumuamua, the first interstellar interloper that has been detected entering the solar system, is unlikely representative of such a population of isotropically distributed objects, favoring the scenario that it originated from a nearby...

    "Learning Cosmology with the First Stars"

    I will describe how upcoming 21-cm measurements during cosmic dawn will provide a trove of new cosmological information. This era saw the formation of the first stars, which excited neutral hydrogen and allowed it to absorb 21-cm photons from the CMB. The timing of this signal carries information on the abundance of the small mini-halos that hosted the first stars, allowing us to probe the matter power spectrum at smaller scales than currently possible. Moreover, I will describe how the relative velocities between dark matter and...

    Climate mapping of exoplanets
    I will present a new analysis of the high resolution spectrum of WASP-49b using Terminator, a code developed to spatially resolve the atmospheres of exoplanets.
    Simulations of hot Jupiters with GCM's predict the presence of a strong equatorial jet, as well as a day-to-night flow. Without spatial resolution, it is only possible to measure a global average velocity of the planet, and hence it is not possible to disentangle these contributions.
    Transit Limb Scanning makes it possible to spatially resolve the atmosphere of an exoplanet during... Read more about ITC Seminar - Tom Louden (University of Warwick UK)

    Minimoons to Planet X: Mapping Solar System Populations with ZTF and LSST

    The small bodies of the Solar System are a valuable tracer of its present-day structure, its evolution, and ultimately provide clues into the early times of its formation. In the next 5 years, the known sample of all small body populations will grow 10-50x, driven largely by large survey programs. For example, the LSST alone will generate a billion measurements of millions of Solar System objects, with simulations predicting ~100,000 new discoveries of nearby NEOs (Jones et al. 2017), 5.5 million for the main...

    Title:  The Big 4 of Mathematical Relativity

     

    Abstract:   The big 4 conjectures of mathematical relativity started life as intuitive guesses by a number of physicists. After decades of work, mathematicians have been able to translate these intuitions into precise mathematical questions that are amenable to confirmation by proof or refutation by counterexample. These conjectures remain wide open at present and my aim will be to describe what they're about, how they are inter-related, whether they're...
