    "New test of the black hole metric with EHT images of Sgr A*"

    Our understanding of astrophysical black holes is predicated on the assumption that they are well described by the  Kerr solution to Einstein’s equations. A promising avenue for testing the Kerr hypothesis is to detect the shadow a black hole casts on the surrounding emission and compare its size and shape to the predictions of the Kerr metric. New horizon-scale images of the Galactic Center black hole Sagittarius A* (Sgr A*) recently published by the Event Horizon Telescope (EHT) allow for new strong-field tests...

    "The ASTRID simulation: the evolution of massive black holes"

    The launch of the next-generation telescopes will soon revolutionize the study of the high-redshift universe and allow us to better understand the evolution of the first galaxies and supermassive black holes. Making full use of future observations will require a new generation of cosmological simulations with large volumes for statistical samples of large structures and with high resolution to model the galaxy formation. In this talk, I will introduce the ASTRID simulation, one of the...

    "Probing Dense Matter with Neutron Star Mergers"

     

    Neutron star mergers provide a unique probe of the dense matter equation of state (EOS) across a wide range of parameter space, from the cold and equilibrated matter of the inspiral, to the shock-heated and higher-density conditions that govern the post-merger evolution. In this talk, I will start with an overview of what we...

    "Unveiling cosmic dawn"

    Abstract:  Cosmic Dawn and the Epoch of Reionization (EoR) are some of the least explored stages of cosmic history. The faint 21-cm signal of hydrogen atoms in the intergalactic medium provides a unique way to probe these epochs by constraining the thermal and ionization history of the Universe. Once this signal is robustly measured, it will inform us about the early populations of stars, galaxies and black holes. In my talk I will discuss the recent advances in the field of observational and theoretical 21-cm cosmology.
