3:00pm –  3:30pm, Akshara Viswanathan Tracing the Milky Way’s ancient footsteps: Insights from chemodynamical investigations of bright and distant metal-poor stars Galaxy formation and evolution is a complex process. The chemodynamical study of metal-poor stars in the Milky Way provides a unique and powerful way of unlocking the secrets of star formation, and the growth

3:00pm –  3:30pm, Rachel Bowens-Rubin The observer that cried Wolf 359: hunting for exoplanets in the fifth-closest system using direct imaging and radial velocity Wolf 359 is a low-mass star in the fifth-closest neighboring system. Because of its relative youth and proximity, Wolf 359 offers a unique opportunity to study substellar companions around M stars

3:00pm –  3:30pm, Heidi White Effective and meaningful engagement of underserved and disproportionately impacted communities in STEM learning Developing science education initiatives which target the needs of underserved and disproportionately impacted groups helps bridge educational disparities and is crucial for equal access to STEM learning. By addressing the specific needs of these communities, we empower

3:00pm –  3:30pm, Mahdi (Sum) Qezlou Cosmology and galaxy evolution with Ly-alpha tomography Ly-alpha tomography surveys have produced 3D maps of the Lya opacity of the intergalactic medium (IGM) at z ~ 2.5 with Mpc resolution, offering a new window to discover high-redshift large-scale structures like the progenitors of present-day massive galaxy groups and clusters.

3:00pm –  3:30pm, Gokul Srinivasaragavan GRB 221009A/SN 2022xiw and GRB 230812B/SN 2023pel – Two Ordinary SNe Associated with Energetic GRBs In this talk, I will present the characterization of two supernovae (SNe) associated with energetic long gamma-ray bursts (LGRBs): GRB 221009A/SN 2022xiw ( https://ui.adsabs.harvard.edu/abs/2023ApJ…949L..39S/abstract) and GRB 230812B/SN 2023pel (https://ui.adsabs.harvard.edu/abs/2023arXiv231014397S/abstract). Due to the extreme rarity of

3:00pm –  3:30pm, Ketan Sand A periodically repeating Fast Radio Burst Fast Radio Bursts (FRBs) are millisecond-duration radio pulses originating from extragalactic distances. This relatively nascent field has experienced rapid growth, particularly since the commencement of the Canadian Hydrogen Intensity Mapping Experiment/FRB (CHIME/FRB), comprehensively monitoring the entire Northern sky at a daily cadence. This effort

3:00pm –  3:30pm, Fabienne Nail Three dimensional simulations of exoplanetary atmosphere escape This talk delves into exoplanetary atmospheres via 3D hydrodynamic simulations, concentrating on atmospheric escape identified through transmission spectroscopy. These escaping atmospheres, spanning up to hundreds of planetary radii, prominently feature metastable helium as a vital tracer. Notably, a substantial fraction of high-resolution helium

3:00pm –  3:30pm, Constantin Gerbig New diffusive instabilities in dusty protoplanetary disks: Setting the stage for planetesimal formation The hydrodynamic behavior of dust in protoplanetary disks, key during the initial stages of planet formation, remains riddled with questions. In particular, there is ambiguity regarding the physical processes that can concentrate dust to densities sufficient for

3:00pm –  3:30pm, Xinfeng Xu What are the radial distributions of density, outflow rates, and cloud structures in the M82 wind? Galactic winds play essential roles in the evolution of galaxies by providing various feedback effects. Despite intensive studies of winds, their radial distributions and feedback are rarely observable. I will present a new such

3:00pm –  3:30pm, Susan Redmond To the stratosphere and beyond: Correcting quasi-static wavefront error drifts in astronomical telescopes The study of both Exoplanets and Dark Matter provide valuable information on how we humans came to exist and whether we are alone in the universe. Directly imaging planets is a primary science goal of the Habitable

3:00pm –  3:30pm, Natasha Latouf Bayesian Analysis for Remote Biosignature Identification on exoEarths (BARBIE): Using Grid-Based Nested Sampling in Coronagraphy Observation Simulations for Molecular Detection We have seen the discovery and confirmation of thousands of exoplanets since the first planet found orbiting a Sun-like star, and we are now on the verge of entering an

3:00pm –  3:30pm, Chun Huang Cracking neutron star mysteries: Physics-driven insights into interior, surface, and exterior by X-ray Timing results The utilization of Pulse Profile modeling techniques could simultaneously provide measurements for Neutron star Mass Radius and offer insights into their hotspot distribution. Presently, these methodologies rely on meta models of the equation of state

3:00pm – 3:30pm, Xiaojing Lin Quantifying the escape of Lya at z=5-6: a census of Lya escape fraction with Ha emitting galaxies spectroscopically confirmed by JWST and VLT/MUSE JWST provides an unprecedented opportunity for unbiased surveys of Hα-emitting galaxies at z>4 with the NIRCam wide-field slitless spectroscopy (WFSS). In this talk, I will present a

3:00pm – 3:30pm, Garrett Levine TESS as a supernovae hunter: constraining supernova progenitors with high cadence photometry at early time The hint for the exact progenitors of various types of supernovae (SNe) lies in the rapidly evolving features at the earliest stage. Such features include the breakout flash of the SN shock through the surface

3:00pm – 3:30pm, Garrett Levine Exoplanet aeronomy: A case study of WASP-69b Aeronomy, the study of Earth’s upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system planets to solar variability in the X-ray and extreme ultraviolet (collectively, “XUV”) bands. Extending comparative

3:00pm – 3:30pm, Elia Pizzati Tracing the rapid evolution of supermassive black holes with High-z Quasar Clustering measurements Quasar clustering measurements have always been a fundamental ingredient on which we built our understanding of supermassive black holes, their accretion mechanisms, and the co-evolution with their host galaxies/halos. Recently, ground-breaking progress has been made in extending
