    ITC Colloquium - Gil Holder (UIUC)

    10:00am to 12:00pm

    Location: 

    Phillips

    "Astrophysics with CMB Surveys"

    High-resolution ground-based CMB experiments provide new perspectives on many areas of astrophysics. As examples, I will talk about current work using the South Pole Telescope as well as possibilities for future CMB experiments. I will discuss luminous mm-wave flares from nearby stars, mapping gravitational lensing on large scales, helium reionization, and searches for cosmic birefringence.

    "Worlds and Suns in Context: Environments & Evolutionary Pathways"

    The growing population of exoplanets and the expanding repertoire of instruments and analysis techniques make it possible to examine moons, planets, and suns within the context of their environments and evolutionary history. In this talk, I discuss how my team leverages stellar evolutionary models, observational survey data, and statistical methods to probe the interactions and evolution of moons, planets, and suns. More specifically, I present the effects of planetary collision, accretion...

    "First applications with a new performance-portable version of Athena++"

     

    The installation of several exascale computing systems this year has enabled new applications in computational astrophysical fluid dynamics that were previously intractable.  However, to exploit such systems the underlying application software must be able to run efficiently on heterogeneous architectures such as GPU clusters. I will describe a re-write of the Athena++ adaptive mesh refinement code using the Kokkos library that enables applications on ...

    "Hidden gems in the circumstellar envelopes of evolved stars"

    As stars approach the end of their lives, they lose large amounts of mass, energy, and momentum through powerful stellar winds and outbursts. The ejection of these outflows has a profound impact on the star and its surroundings; thus, understanding it is crucial for both stellar and galactic evolution models. Indeed, the circumstellar environments of evolved stars are a tapestry of intricate structures, often adorned with shells, clumps, arcs, disks, jets and spirals. Detailed, multi-dimensional simulations together...

    "The evolution of cool stars and the planets they host"

    Though tremendous progress has been made to understand the population of exoplanets as a whole, we still know little about how planets evolve over time for one main reason: the ages of stars are difficult to measure. There are many methods for measuring stellar ages but rotation-dating, also known as 'gyrochronology', may be unparalleled for cool main-sequence stars. In this talk I will discuss the potential of gyrochronology and recent advances made in understanding the rotational and magnetic evolution of cool stars. I will...

    "Dynamical modification of stellar populations during cluster formation"

    Stars are primarily formed in clustered environments in giant molecular clouds. Stars are also primarily found in binary or higher order multiple systems. This hierarchy of binaries inside clusters, particularly at early times, means that binary systems interact with other stars from the first moments of their life. Both the binaries and the cluster will be changed as a result of these encounters.  Taking the effects of stellar dynamics into account is an important component to furthering our understanding of...
