The origin of the diverse morphologies and kinematics of Milky Way-mass galaxies in the FIRE-2 simulations
Shea Garrison-Kimmel, Philip F. Hopkins, Andrew Wetzel +11
We use hydrodynamic cosmological zoom-in simulations from the FIRE project to explore the morphologies and kinematics of fifteen Milky Way (MW)-mass galaxies. Our sample ranges fro…
Discovery and Characterization of 3000+ Main-Sequence Binaries from APOGEE Spectra
Kareem El-Badry, Yuan-Sen Ting, Hans-Walter Rix +7
We develop a data-driven spectral model for identifying and characterizing spatially unresolved multiple-star systems and apply it to APOGEE DR13 spectra of main-sequence stars. Bi…
The origin of ultra diffuse galaxies: stellar feedback and quenching
T. K. Chan, D. Kereš, A. Wetzel +5
We test if the cosmological zoom-in simulations of isolated galaxies from the FIRE project reproduce the properties of ultra diffuse galaxies. We show that stellar feedback-generat…
Signatures of unresolved binaries in stellar spectra: implications for spectral fitting
Kareem El-Badry, Hans-Walter Rix, Yuan-Sen Ting +5
The observable spectrum of an unresolved binary star system is a superposition of two single-star spectra. Even without a detectable velocity offset between the two stellar compone…
How To Model Supernovae in Simulations of Star and Galaxy Formation
Philip F. Hopkins, Andrew Wetzel, Dusan Keres +6
We study the implementation of mechanical feedback from supernovae (SNe) and stellar mass loss in galaxy simulations, within the Feedback In Realistic Environments (FIRE) project.…
Gas kinematics, morphology, and angular momentum in the FIRE simulations
Kareem El-Badry, Eliot Quataert, Andrew Wetzel +8
We study the z=0 gas kinematics, morphology, and angular momentum content of isolated galaxies in a suite of cosmological zoom-in simulations from the FIRE project spanning $M_{\st…
The statistical challenge of constraining the low-mass IMF in Local Group dwarf galaxies
Kareem El-Badry, Daniel R. Weisz, Eliot Quataert
We use Monte Carlo simulations to explore the statistical challenges of constraining the characteristic mass () and width () of a lognormal sub-solar initial mass function…
