"Artificial Intelligence for Exceptional Interiors" Neutron stars are exceptionally dense. They offer a unique window into understanding the mysterious equation of state of dense matter, which can be probed via radio and X-ray observations of pulsars. Sudden spin-ups, mainly detected at radio...
"Neutron star magnetic...
"Star formation in the first billion years: a James Webb Space Telescope perspective" The first billion years of cosmic history witnessed the formation and build-up of the first galaxies, likely through a bursty process characterised by stochastic bursts of star formation followed by more...
"The role of environment in the star-formation and evolution of galaxies at Cosmic noon" The cosmic star-formation rate density, molecular gas density and the AGN activity of the Universe peak at z ∼ 2-3, showing the Universe is most active at this epoch. The nature of the galaxies at these...
"Dancing in the Dark: Data, Models, and the Milky Way's Dark Matter" In this talk, I will explore the interfacing of simulations, observations, and machine learning techniques to construct a detailed map of dark matter in the Milky Way, and argue that progress now hinges on the dance between...
"Cores, Outskirts, and Streams: Probing the Formation and Evolution of Globular Clusters" Globular clusters are among the oldest stellar systems in the Universe, acting as long-lived fossils of the early stages of galaxy formation. Their ages, dynamics, and chemical patterns show that they were...
"From Star Formation to Hot Gas: Tracing the Baryonic Universe to Unmask Fundamental Physics" The standard cosmological model provides a remarkable framework for understanding the dark universe, but the visible matter i.e. baryons introduces complex, non-linear astrophysics that precision...
"Extended body effects and gravitational wave astronomy" Born in 2015 with the first direct detection of gravitational waves emitted by a merging black hole binary, gravitational wave astronomy has since grown into a mature observational science. Hundreds of signals detected by ground-based...
"Decoding Galaxies & Star Formation Feedback with 100,000 Star Clusters: PHANGS-HST & JWST today, the future with HWO" The PHANGS-HST and JWST Treasury Programs have produced the most extensive inventories to date of optically visible and dust-obscured star clusters across nearby...
"Spiral arms in stellar and gaseous disks: engines of galaxy morphological transformation" Spirals are iconic features of galaxies, and yet conventional theoretical models for how they emerge and evolve only partially capture their observed traits and their connections to their host disks....
