Igniting Galaxy Formation in the Postreionization Universe, II: Nature versus Nurture
Jorge Moreno, Defne Aluç, Eisha López +7
Although the ultraviolet background from reionization is thought to conspire against the smallest halos, some gas-rich halos in the post-reionization Universe still form stars. We…
Observing Co-Located Neutral and Ionized Gas-Phase Iron Depletion in the Magellanic Clouds
Yun Qi Li, Jessica K. Werk, Caleb R. Choban +5
Depletion is the observed phenomenon where gas-phase elemental abundances are reduced through accretion onto dust grains. We measure neutral gas-phase elemental abundances (S, Fe)…
Ashes of FIRE: Modeling Dust Grain Size Evolution in the Local Group with FIRE
Caleb R. Choban, Samir Salim, Dušan Kereš +2
We introduce a new, discretized grain size evolution model, incorporated into the GIZMO code and coupled with FIRE-3 stellar feedback and ISM physics, to investigate variations in…
A Dusty Dawn: Galactic Dust Buildup at
Caleb R. Choban, Samir Salim, Dušan Kereš +2
Over the last decade, the Atacama Large Millimeter Array has revealed massive, dusty star-forming galaxies at , and the James Webb Space Telescope is primed to uncover e…
A Dusty Locale: Evolution of Galactic Dust Populations from Milky Way to Dwarf-Mass Galaxies
Caleb R. Choban, Dušan Kereš, Karin M. Sandstrom +3
Observations indicate dust populations vary between galaxies and within them, suggesting a complex life cycle and evolutionary history. Here we investigate the evolution of galacti…
FIRE-3: Updated Stellar Evolution Models, Yields, & Microphysics and Fitting Functions for Applications in Galaxy Simulations
Philip F. Hopkins, Andrew Wetzel, Coral Wheeler +18
Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we…
The Galactic Dust-Up: Modeling Dust Evolution in FIRE
Caleb R. Choban, Dusan Keres, Philip F. Hopkins +3
Recent strides have been made developing dust evolution models for galaxy formation simulations but these approaches vary in their assumptions and degree of complexity. Here we int…
The First Brown Dwarf/Planetary-Mass Object in the 32 Orionis Group
Adam J. Burgasser, Mike A. Lopez, Eric E. Mamajek +6
The 32 Orionis group is a co-moving group of roughly 20 young (24 Myr) M3-B5 stars 100 pc from the Sun. Here we report the discovery of its first substellar member, WISE J052857.69…
Characterization of the Very Low Mass Secondary in the GJ 660.1AB System
Christian Aganze, Adam J. Burgasser, Jacqueline K. Faherty +7
We present spectroscopic analysis of the low mass binary star system GJ 660.1AB, a pair of nearby M dwarfs for which we have obtained separated near-infrared spectra (0.9-2.5 m)…
