1. Karan Jani (Vanderbilt) "Detection of Lite-Intermediate Mass Black Holes in LIGO-Virgo"

 In this talk, I will give an overview of the 150 solar mass binary black hole merger that was recently announced by the LIGO-Virgo Collaboration. I will discuss the process that went behind inferring the astrophysical properties of this source. And will show the observing scenario of this new black hole population for the upcoming ESA/NASA space mission LISA.

1. Catherine Zucker (Harvard) "**3D Dust Mapping in the Age of Gaia"**  
      
    Much of our knowledge about the formation of stars comes from observations of our solar neighborhood, less than 2 kpc from the Sun. However, before 2018, accurate distance measurements needed to transform the 2D sky into a faithful 3D physical picture of stars and the interstellar clouds that form them were few and far between. In this talk, I will discuss how the rise of *Gaia* and large photometric surveys — in combination with new data science and visualization techniques — are quickly changing the landscape. In particular, I will show how 3D dust maps have received a huge distance resolution boost from *Gaia*, allowing us to resolve the 3D spatial structure of our local interstellar medium at large dynamic range (and on scales comparable to simulations) for the first time. On small scales, I will present a new analysis of the detailed 3D spatial topologies and thicknesses of local molecular clouds. And on large scales, I will show how many of these clouds are connected in a 2.7-kpc-long structure called the Radcliffe Wave, which redefines our understanding of the Local Arm nearby.
