A 3D View of Orion: I. Barnard's Loop
Michael M. Foley, Alyssa Goodman, Catherine Zucker +11
Barnard's Loop is a famous arc of H emission located in the Orion star-forming region. Here, we provide evidence of a possible formation mechanism for Barnard's Loop and compare…
Stochastic Modelling of Star Formation Histories III. Constraints from Physically-Motivated Gaussian Processes
Kartheik G. Iyer, Joshua S. Speagle, Neven Caplar +4
Galaxy formation and evolution involves a variety of effectively stochastic processes that operate over different timescales. The Extended Regulator model provides an analytic fram…
Code Comparison in Galaxy Scale Simulations with Resolved Supernova Feedback: Lagrangian vs. Eulerian Methods
Chia-Yu Hu, Matthew C. Smith, Romain Teyssier +8
We present a suite of high-resolution simulations of an isolated dwarf galaxy using four different hydrodynamical codes: {\sc Gizmo}, {\sc Arepo}, {\sc Gadget}, and {\sc Ramses}. A…
Empirical Dust Attenuation Model Leads to More Realistic UVJ Diagram for TNG100 Galaxies
Gautam Nagaraj, John C. Forbes, Joel Leja +2
Dust attenuation varies substantially from galaxy to galaxy and as of yet cannot be reproduced from first principles in theoretical models. In Nagaraj et al. (2022), we developed t…
Gas Accretion Can Drive Turbulence in Galaxies
John C. Forbes, Razieh Emami, Rachel S. Somerville +11
The driving of turbulence in galaxies is deeply connected with the physics of feedback, star formation, outflows, accretion, and radial transport in disks. The velocity dispersion…
The Dwarf Galaxy Population at : A Catalog of Emission Lines and Redshifts from Deep Keck Observations
John Pharo, Yicheng Guo, Guillermo Barro Calvo +18
We present a catalog of spectroscopically measured redshifts over and emission line fluxes for 1440 galaxies. The majority (65\%) of the galaxies come from the HA…
A Bayesian Population Model for the Observed Dust Attenuation in Galaxies
Gautam Nagaraj, John C. Forbes, Joel Leja +2
Dust plays a pivotal role in determining the observed spectral energy distribution (SED) of galaxies. Yet our understanding of dust attenuation is limited and our observations suff…
On the robustness of the velocity anisotropy parameter in probing the stellar kinematics in Milky Way like galaxies: Take away from TNG50 simulation
Razieh Emami, Lars Hernquist, Mark Vogelsberger +8
We analyze the velocity anisotropy of stars in real and energy space for a sample of Milky Way-like galaxies in the TNG50 simulation. We employ different selection criteria, includ…
