Exoplanet atmospheres with high-resolution spectroscopy: chemistry, isotopes, and dynamics
Exoplanet atmospheres with imprints from their history open an important avenue to trace the origin and evolution of planets. With high-dispersion spectroscopy, we can resolve atomic and molecular spectral features into unique forests of lines that serve as fingerprints for identifying different species and probing structures and dynamics of exoplanet atmospheres. I will talk about high-resolut...

Analytical Insights into Dark Matter Deficient Galaxies
Recent observations reported a puzzling dearth of dark matter (DM) in a fraction of massive high-z galaxies and dwarf galaxies, challenging current simulation predictions within the standard ΛCDM scenario. This discrepancy underscores our limited understanding of the halo and galaxy structural evolution. Here, I will present a novel unified analytical framework for galaxy dynamical evolution d...

New Results in Three-Dimensional Core-Collapse Supernova Theory
The theory of core-collapse supernova (CCSN) has evolved significantly in the past few years with the help of long term 3D simulations. In this talk, I will present many new scientific results based on the large set of CCSN simulations calculated by the code Fornax, focusing on the important role of three dimensional effects. I will talk about theoretical observables such as explosion energy, ...

Gaia + Bayesian Power: A Deep Dive into Open Cluster Mass Function & Binaries
Open clusters (OCs) are cradles of stars and building blocks of galaxies, offering insights into how stars and galaxies form. It is essential to precisely measure the parameters of OCs, such as age, metallicity, distance, dust extinction, stellar mass function (MF), and binary fraction. I propose a novel Bayesian framework that can identify OC candidates and simultaneously estimate these parame...

Revealing Dark Matter under the Lens
Unveiling the true nature of Dark Matter (DM), which manifests itself only through gravity, is one of the principal quests in physics. Leading candidates for DM are weakly interacting massive particles (WIMPs) or ultralight bosons (axions), at opposite extremes in mass scales, that have been postulated by competing theories to solve deficiencies in the Standard Model of particle physics. Wherea...
