The Galactic Interstellar Object Population: A Framework for Prediction and Inference
Matthew J. Hopkins, Chris Lintott, Michele T. Bannister +2
The Milky Way is thought to host a huge population of interstellar objects (ISOs), numbering approximately around the Sun, which are formed and shaped by…
The interplay between feedback, accretion, transport and winds in setting gas-phase metal distribution in galaxies
Piyush Sharda, Omri Ginzburg, Mark R. Krumholz +5
The recent decade has seen an exponential growth in spatially-resolved metallicity measurements in the interstellar medium (ISM) of galaxies. To first order, these measurements are…
Characterizing the Conditional Galaxy Property Distribution using Gaussian Mixture Models
Yucheng Zhang, Anthony R. Pullen, Rachel S. Somerville +5
Line-intensity mapping (LIM) is a promising technique to constrain the global distribution of galaxy properties. To combine LIM experiments probing different tracers with tradition…
How Low Can Q Go?
John C. Forbes
Gravitational instability plays a substantial role in the evolution of galaxies. Various schemes to include it in galaxy evolution models exist, generally assuming that the Toomre…
The star formation history of the Sco-Cen association. Coherent star formation patterns in space and time
Sebastian Ratzenböck, Josefa E. Großschedl, João Alves +13
We reconstruct the star formation history of the Sco-Cen OB association using a novel high-resolution age map of the region. We develop an approach to produce robust ages for Sco-C…
Arkenstone I: A Novel Method for Robustly Capturing High Specific Energy Outflows In Cosmological Simulations
Matthew C. Smith, Drummond B. Fielding, Greg L. Bryan +11
Arkenstone is a new model for multiphase, stellar feedback driven galactic winds designed for inclusion in coarse resolution cosmological simulations. In this first paper of a seri…
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…
Where to find over-massive brown dwarfs: new benchmark systems for binary evolution
Dorsa Majidi, John C. Forbes, Abraham Loeb
Under the right conditions brown dwarfs that gain enough mass late in their lives to cross the hydrogen burning limit will not turn into low-mass stars, but rather remain essential…
A Solar System formation analogue in the Ophiuchus star-forming complex
John C. Forbes, João Alves, Douglas N. C. Lin
Anomalies among the daughter nuclei of the extinct short-lived radionuclides (SLRs) in the calcium-aluminum-rich inclusions (CAIs) indicate that the Solar System must have been bor…
Touching the Stars: Using High-Resolution 3D Printing to Visualize Stellar Nurseries
Nia Imara, John C. Forbes, James C. Weaver
Owing to their intricate variable density architecture, and as a principal site of star formation, molecular clouds represent one of the most functionally significant, yet least un…
Characterizing mass, momentum, energy and metal outflow rates of multi-phase galactic winds in the FIRE-2 cosmological simulations
Viraj Pandya, Drummond B. Fielding, Daniel Anglés-Alcázar +14
We characterize mass, momentum, energy and metal outflow rates of multi-phase galactic winds in a suite of FIRE-2 cosmological "zoom-in" simulations from the Feedback in Realistic…
The physics of gas phase metallicity gradients in galaxies
Piyush Sharda, Mark R. Krumholz, Emily Wisnioski +3
We present a new model for the evolution of gas phase metallicity gradients in galaxies from first principles. We show that metallicity gradients depend on four ratios that collect…
On the origin of the mass-metallicity gradient relation in the local Universe
Piyush Sharda, Mark R. Krumholz, Emily Wisnioski +3
In addition to the well-known gas phase mass-metallicity relation (MZR), recent spatially-resolved observations have shown that local galaxies also obey a mass-metallicity gradient…
