    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 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...
