"How Protoplanetary Disks Accrete — New Insights from Disk Sizes and IR Spectroscopy" Physical processes that redistribute or remove angular momentum from protoplanetary disks can drive mass accretion onto the star and affect the outcome of planet...

"High-energy neutrino emission associated with tidal disruption events" Tidal disruption events (TDEs) are a good probe of supermassive black holes (SMBHs) at the center of inactive galaxies. A star approaches the SMBH in a parabolic orbit, is destroyed...

"Explaining the winds of asymptotic giant branch stars: Recent progress" Evolved stars and their winds play a crucial role for galactic chemical evolution, including the origin of building blocks for planets and life. Essential chemical elements, like...

" The cool CGM in absorption with large spectroscopic surveys" The gas flows in the circumgalactic medium (CGM) play a pivotal role in several key processes regulating galaxy formation, implying that our understanding of galaxy formation is limited by our...

" Reconstructing the Cosmic Web at High Noon with Lyman Alpha Tomography" Cosmic High Noon is defined by the peak of star formation, occurring at z~2.5. Not only is understanding the dynamics of this epoch critical for a unified picture of galaxy...

" A new window on star formation history at the Galactic Center" As the closest galactic nucleus, Milky Way's Nuclear Star Cluster (NSC) provides a unique opportunity to resolve the stellar population and to study its composition and star formation in...

" Probing the standard cosmological model with the population of binary black-holes" Gravitational-wave (GW) detections are rapidly increasing in number, enabling precise statistical analyses of the population of compact binaries. In this talk I will show...

" Convection in Common Envelopes" The common envelope (CE) phase of binary evolution is the primary theorized mechanism to produce short-period, compact binaries. The efficiency of energy transfer between the two stars of the CE, $\alpha_{CE}$, and the...

" Recovering the Density Fields inside Quasar Proximity Zones at z~6" The matter density field at z~6 is very challenging to probe. One of the traditional methods that work successfully at lower redshift is the Lyman-alpha forest in quasar spectra...

" Evolution of Stellar Feedback from Reionization to The Milky Way: A Diverse Toolset of Imaging, Spectroscopy, and Modeling for Understanding the Impact of Massive Stars" Massive stars contribute incredible amounts of energy to their surroundings across...
