Understanding the Origin and Dynamical Evolution of the Unique Open Star Cluster Berkeley 20 using FIRE Simulations
Alessa I. Wiggins, Jamie R. Quinn, Micah Oeur +11
Open clusters (OCs) act as key probes that can be leveraged to constrain the formation and evolution of the Milky Way (MW)'s disk, as each has a unique chemical fingerprint and wel…
Spiral Structure Diversity in Milky Way Analogs from TNG50: The Role of Gas and Disk Dynamics
Soumavo Ghosh, Elena D'Onghia
The generation of spiral arms and the mechanisms controlling their properties within a realistic cosmological framework - the complete understanding is still beyond our grasp. Usin…
Azimuthal Misalignments in Stellar Warp Structure as Dynamical Tracers of Mergers in Milky Way-like Galaxies
Lekshmi Thulasidharan, Elena D'Onghia, Robert Benjamin
We investigate the origin of warps in stellar disks using high-resolution Milky Way analogs from the IllustrisTNG50 simulation. Focusing on galaxies that experienced a major merger…
The First RELHIC? Cloud-9 is a Starless Gas Cloud
Gagandeep S. Anand, Alejandro BenÃtez-Llambay, Rachael Beaton +3
Five-hundred-meter Aperture Spherical Telescope (FAST) observations have recently identified a compact HI cloud (hereafter Cloud-9) in the vicinity of the spiral galaxy M94. This i…
A Pre-Infall Magellanic Analog-Corona and Stream formation in the \textsc{HESTIA} cosmological simulations
Robin Chisholm, Elena D'Onghia, Noam Libeskind +3
We identify and investigate a pre-infall analog of the Large and Small Magellanic Clouds (LMC, SMC) in the HESTIA suite of constrained cosmological simulations. The system, dynamic…
The large-scale kinematics of young stars in the Milky Way disc: first results from SDSS-V
Eleonora Zari, Jaime Villaseñor, Marina Kounkel +17
We present a first large-scale kinematic map of 50,000 young OB stars ( K), based on BOSS spectroscopy from the Milky Way Mapper OB program in the on…
