    Black hole demography in the era of gravitational-wave astronomy

     

    The era of gravitational-wave astronomy has just begun and the formation channels of binary black holes (BBHs) are one of its most debated questions. In my talk, I will discuss what we learned and what we still do not understand about the formation of black holes from the collapse of massive stars, focusing on the impact of pair instability and stellar rotation. Based on novel population-synthesis calculations, I will show that massive binary stars can evolve into BBHs with total mass up to ~130...

    The ages of stars

    Stellar ages are critical to understanding the formation history of the Milky Way and the evolution of planetary systems,

    but the ages of stars are extremely difficult to measure. In this talk I will discuss recent advances in dating main

    sequence stars, particularly in the field of gyrochronology (rotation-dating). I will also describe methodology used to

    combine different dating methods, and how combining information can improve the precision and accuracy of stellar

    ages and all stellar parameters....

    "Think Globally Act Locally: overcoming the multiscale challenge of modeling galaxy formation"
     

    Understanding how galaxies form and evolve in a cosmological context is one of the grand challenges in astrophysics. Galaxies are probes of cosmology, and are the hosts for stars, planets, interstellar gas, and black holes. Galaxies are shaped by the formation of large scale structure, driven on cosmological scales of Mpc and above, but may also be shaped by processes occurring on scales as much as nine orders of magnitude smaller, those of individual stars and...

    First Alpha and Iron Element Abundances in the Outer Disk, Giant Stellar Stream, and Inner Halo of Andromeda
     
    Measurements of chemical abundances ([Fe/H] and [alpha/Fe]) in individual stars can probe the formation history of a galaxy. In contrast to the Milky Way, relatively little is known about [alpha/Fe] of individual...

    "Probes of standard and non-standard cosmology"

    The large scale  peculiar  motions (deviations from a pure Hubble flow) of  galaxies are our only probe of the 

    three-dimensional distribution of the dark matter on large scales. Implications of the observed motions 

    in the late-time Universe will be discussed, with emphasis  on some long term challenges arising from the nature of these observations. 

    The talk will include a discussion of generic predictions of dark sector modifications to GR for the large scale...
