    "Centihertz gravitational-wave astronomy: from hierarchical black-hole triples to ultra-compact white-dwarf binaries"

    Future space-borne gravitational-wave (GW) observatories are sensitive to a rich array of astrophysical systems in the centihertz band. Here we focus on two science cases specifically. The first is hierarchical black-hole (BH) triple systems in galactic nuclei. Such a system consists of a stellar-mass inner binary orbiting around a supermassive BH (SMBH). We show that the orbital angular momentum (AM) of the inner binary will precess around the outer orbital... Read more about ITC Colloquium - Hang Yu (Caltech)

    " Tracing Dynamical History of TESS Warm Jupiters"

    Warm Jupiters are a key missing piece in our understanding of how planetary systems form and evolve. It is currently debated whether Warm Jupiters form in situ or undergo disk or high eccentricity tidal migration. Using the Transiting Exoplanet Survey Satellite (TESS), we discover and characterize Warm Jupiters to trace...

    "Lyman-alpha emission and transmission during the Epoch of Reionization"

    The visibility of high-redshift Lyman-alpha emitting galaxies (LAEs) provides important constraints on galaxy formation processes and the Epoch of Reionization (EoR). However, predicting realistic and representative statistics for comparison with observations represents a significant challenge in the...

    "From clouds to planets: the astrochemical link"

     

    All ingredients to make stars like our Sun and planets like our Earth are present in dense cold interstellar clouds. In these "stellar-system precursors" an active chemistry is already at work, as demonstrated by the presence of a rich variety of organic molecules in the gas phase and icy mantles encapsulating the sub-micrometer dust grains, the building blocks of planets. Here, I’ll present a journey from the earliest phases of star formation to protoplanetary disks, with links to our Solar System, highlighting the...

    Ionizing Flux at High-redshift & The Future of Astronomical Conferences

    In this split talk, I will be covering two challenging areas of astronomy. 

     

    Spectroscopic Confirmation of Ionizing Flux from Individual High-redshift Galaxies

    Lyman continuum (LyC) galaxies (LCGs) are a high-redshift population (z ~ 3–5) that exhibit escaping ionizing flux below the Lyman break (< 912 A). This valuable and elusive population of galaxies serve as the closest observable proxies, in redshift and properties, to those...

    "From galaxies to faces: recognizing the implications of Artificial Intelligence in astronomy and society"

    Abstract:  Artificial Intelligence (AI) refers to a set of techniques that rely primarily on the data itself for the construction of a quantitative model. AI has arguably been in development for three quarters of a century, but there has been a recent resurgence in research and application. This current (third) wave of AI progress is...

    "Learning the properties of our Galaxy with Stellar Streams"

    The Galactic halo is criss-crossed by long stellar streams that are probably the remnants of defunct globular clusters and dwarf galaxies. I will present the recent discoveries of these structures including several streams that can be traced back to well known halo features. While streams clearly inform us in a direct way about past accretions onto our Galaxy, their most promising property is that they allow us to measure the Galactic acceleration field and they may possibly allow us to reveal the presence of small-...

    "How to find life on exoplanets: Challenges, ideas and adventures"

    The first exoplanets orbiting in the temperate, Habitable Zone, have
    revolutionized the field of the search for life in the cosmos. With
    their discovery comes the question of how you can tell if there are
    signs of a life watching remotely. Where should we look in terms of
    wavelength, host star, planet size and mass - among many other.
