Abstract: Gravitational wave and electromagnetic observations of strongly gravitating systems allow us not only to probe black holes and neutron stars, but also have the potential to uncover new fundamental physics. Superradiant bosonic clouds and...

High-precision radial velocity measurements are crucial for exoplanet detection and characterization. Efforts to improve the precision have been made over the recent decades, with significant advancements in instrumentation, data reduction...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Abstract: Both physics and neuroscience seek to understand how the edges and nodes of a network dictate its function. But until recently, it was not possible to quantitatively explore the relation between the structure and function of a biological...

Although massive stars have a profound influence on the Universe at every scale, from the evolution of galaxies to the formation of the elements necessary for life, the answers to key questions about their mass loss and explodability are unknown...

In this talk, I will present our recent progress on constraining the physical properties of the ''cool'' (T ~ 104K) phase of the circumgalactic medium (CGM) via modeling Lya emission and low-ionization-state (LIS) metal absorption lines. We...

 Gravitational waves have uncovered a treasure trove of nearly 90 merging black holes and neutron stars, each with its own unique story to tell. In this talk, our focus centers on black hole spins, seeking to decipher the secrets hidden within...

This presentation examines the behind-the-scenes details of the creation of the heart of the JWST Observatory, it’s mirrors. We overcame many technical challenges, including “Micro-Yield”, pitting and “edge-relief”; not to mention that the particles...
