"The Neutral Islands during the Late Epoch of Reionization" Abstract: Th e growth of isolated ionized regions during the early stage of reionization is well described by the “bubble model”. However, the basic assumption of isolated and spherical ionized...

"The Formation and Evolution of Close Binaries and Planets " Abstract: The formation and orbital migration of close binaries and planets remain a mystery. The majority of very close binaries have outer tertiary companions, suggesting Kozai-Lidov...

How Black Holes Shape Globular Clusters Recent numerical simulations and observational indications have suggested that globular clusters (GCs) may contain large populations of stellar-mass black holes (BHs). This has important implications to...

Kung-Yi Su (Caltech): "Suppressing cooling flows in massive galaxies with turbulent stirring" We investigate the cooling flow problem of massive galaxies with halo masses of 10^12 - 10^14 solar masses using high-resolution idealized, non-cosmological...

Awarding of the Keto Prize for the best thesis in theoretical astrophysics by a student at the CfA, as selected by the Senior Members of the ITC.

Ana Bonaca (ITC): "Gaia DR2 View of the GD-1 Stellar Stream" Anna Rosen (ITC): "The Formation of Massive Stars with Radiative and Outflow Feedback" Anna Barnacka (CfA): " The Art of Turning Galaxies into Telescopes" Anna Pancoast (ITC): "Stability of the...

Title: Improving Gaia Parallax Precision with a Data-Driven Model of Stars Abstract: Gaia will eventually generate astrometric information, including parallax, for 2 billion stars. A lot of these distance estimates will be very noisy. I will talk about...

"APOGEE Chemical Abundances of the Sagittarius Dwarf Galaxy System" The Apache Point Observatory Galactic Evolution Experiment provides the opportunity of measuring elemental abundances for C, N, O, Na, Mg, Al, Si, P, K, Ca, V, Cr, Mn, Fe, Co, and Ni in...
