The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations

Desika Narayanan, Paul Torrey, Massimiliano Parente +16

We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…

H-alpha emission in local galaxies: star formation, time variability and the diffuse ionized gas

Sandro Tacchella, Aaron Smith, Rahul Kannan +6

The nebular recombination line H is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H radiative transfer…

The Illustris Simulation: Public Data Release

Dylan Nelson, Annalisa Pillepich, Shy Genel +12

We present the full public release of all data from the Illustris simulation project. Illustris is a suite of large volume, cosmological hydrodynamical simulations run with the mov…

The Growth of Dust in Galaxies in the First Billion Years with Applications to Blue Monsters

Desika Narayanan, Paul Torrey, Daniel Stark +9

A combination of JWST observations at z~12-14 and ALMA observations of extremely dust-rich systems at z~6 has demonstrated that dust grows extremely fast in the early Universe, wit…

A Framework for Modeling Polycyclic Aromatic Hydrocarbon Emission in Galaxy Evolution Simulations

Desika Narayanan, J. D. Smith, Brandon Hensley +7

We present a new methodology for simulating mid-infrared emission from polycyclic aromatic hydrocarbons (PAHs) in galaxy evolution simulations. To do this, we combine theoretical m…

The Halos and Environments of Nearby Galaxies (HERON) I: Imaging, Sample Characteristics, and Envelope Diameters

R. Michael Rich, Aleksandr Mosenkov, Henry Lee-Saunders +16

We use a dedicated 0.7-m telescope to image the halos of 119 galaxies in the Local Volume to mag/arcsec. The sample is primarily from the 2MASS Large Galaxy A…
