Inferring the Morphology of Stellar Distribution in TNG50: Twisted and Twisted-Stretched shapes
Razieh Emami, Lars Hernquist, Charles Alcock +9
We investigate the morphology of the stellar distribution in a sample of Milky Way (MW) like galaxies in the TNG50 simulation. Using a local in shell iterative method (LSIM) as the…
A Framework for Multiphase Galactic Wind Launching using TIGRESS
Chang-Goo Kim, Eve C. Ostriker, Drummond B. Fielding +6
Galactic outflows have density, temperature, and velocity variations at least as large as that of the multiphase, turbulent interstellar medium (ISM) from which they originate. We…
DM halo morphological types of MW-like galaxies in the TNG50 simulation: Simple, Twisted, or Stretched
Razieh Emami, Shy Genel, Lars Hernquist +8
We present a comprehensive analysis of the shape of dark matter (DM) halos in a sample of 25 Milky Way-like galaxies in TNG50 simulation. Using an Enclosed Volume Iterative Method…
First results from SMAUG: Characterization of Multiphase Galactic Outflows from a Suite of Local Star-Forming Galactic Disk Simulations
Chang-Goo Kim, Eve C. Ostriker, Rachel S. Somerville +6
Large scale outflows in star-forming galaxies are observed to be ubiquitous, and are a key aspect of theoretical modeling of galactic evolution in a cosmological context, the focus…
The Diversity and Variability of Star Formation Histories in Models of Galaxy Evolution
Kartheik G. Iyer, Sandro Tacchella, Shy Genel +10
Understanding the variability of galaxy star formation histories (SFHs) across a range of timescales provides insight into the underlying physical processes that regulate star form…
Stochastic modelling of star-formation histories II: star-formation variability from molecular clouds and gas inflow
Sandro Tacchella, John C. Forbes, Neven Caplar
A key uncertainty in galaxy evolution is the physics regulating star formation, ranging from small-scale processes related to the life-cycle of molecular clouds within galaxies to…
First results from SMAUG: Uncovering the Origin of the Multiphase Circumgalactic Medium with a Comparative Analysis of Idealized and Cosmological Simulations
Drummond B. Fielding, Stephanie Tonnesen, Daniel DeFelippis +12
We examine the properties of the circumgalactic medium (CGM) at low redshift in a range of simulated Milky Way mass halos. The sample is comprised of seven idealized simulations, a…
First results from SMAUG: The need for preventative stellar feedback and improved baryon cycling in semi-analytic models of galaxy formation
Viraj Pandya, Rachel S. Somerville, Daniel Anglés-Alcázar +10
Semi-analytic models (SAMs) are a promising means of tracking the physical processes associated with galaxy formation, but many of their approximations have not been rigorously tes…
First results from SMAUG: Insights into star formation conditions from spatially-resolved ISM properties in TNG50
Bhawna Motwani, Shy Genel, Greg L. Bryan +11
Physical and chemical properties of the interstellar medium (ISM) at sub-galactic (kpc) scales play an indispensable role in controlling the ability of gas to form stars. As…
A PDF PSA, or Never gonna set_xscale again -- guilty feats with logarithms
John C. Forbes
In the course of doing astronomy, one often encounters plots of densities, for example probability densities, flux densities, and mass functions. Quite frequently the ordinate of t…
