    "The Search for Primordial Gravitational Waves"

    Abstract: Observations of the cosmic microwave background so far reveal no evidence of gravitational waves in the very early universe. I will discuss what a detection or an improved upper limit could tell us about cosmology, particle physics, and gravity, and specifically what we hope to learn from the next generation of ground-based CMB polarization instruments.

    "X-ray tomography of molecular clouds"

     
    Abstract:  While molecular clouds are among the coldest objects in the Milky Way, an illumination by flares from Sgr A* turns them into powerful X-ray sources. By studying X-ray emission from molecular clouds we learn about the past activity of our Galactic Center over the last few hundred years. The same data provide unique probes of the inner structure of molecular clouds, such as, the density probability distribution function or line of sight positions, among others. We discuss constraints on clouds properties that are...

    "Identifying Binary Black Holes formed in Dense Stellar Environments"

    Abstract: The recent detections of gravitational waves from merging binary black holes have the potential to revolutionize our understanding of compact object astrophysics. But to fully utilize this new window into the universe, we must compare these observations to detailed models of binary black hole formation throughout cosmic time. In this talk, I will review our current understanding of cluster dynamics, describing how binary black holes can be formed through gravitational interactions in dense stellar...

    "Circumbinary Accretion: From Supermassive Binary Black Holes to Circumbinary Planets"
     
    Circumbinary disks have been observed in a number of young stellar systems, and are the birth place for circumbinary planets found by the Kepler misssion. They are also expected to exist around supermassive black hole binaries as a consequence of accretion from the interstellar medium following galaxy mergers. I will discuss recent works on numerical modeling of circumbinary accretion, focusing short-...

    Beyond Advanced LIGO: the future of ground based observations
     
    Abstract: Advanced LIGO started the era of gravitational wave astronomy during its first observing run, O1, in 2015. Since then, the international gravitational wave community has been making plans to define the future of ground based gravitational wave observations. In this talk I will discuss current ideas for extending the astrophysical reach of ground based gravitational wave detectors up to a factor 10-20 beyond Advanced LIGO.

    "The KELT Transit Survey: Hot Planets around Hot, Bright Stars" 

     

    ABSTRACT: The KELT Transit Survey consists of a pair of small-aperture, wide-angle automated telescope located at Winer Observatory in Sonoita, Arizona and the South African Astronomical Observatory (SAAO) in Sutherland, South Africa. Together, they are surveying roughly 60% of the sky for transiting planets. By virtue of their small apertures (42 mm) and large fields-of-view (26 degrees x 26 degrees), KELT is most sensitive to hot Jupiters transiting relatively bright (V~8-11), and thus relatively hot...
