Comparing the Locations of Supernovae to CO (2-1) Emission in their Host Galaxies
Ness Mayker Chen, Adam K. Leroy, Laura A. Lopez +19
We measure the molecular gas environment near recent ( yr old) supernovae (SNe) using or pc resolution CO (2-1) maps from the PHANGS-ALMA survey of nearb…
PHANGS: Constraining Star Formation Timescales Using the Spatial Correlations of Star Clusters and Giant Molecular Clouds
Jordan A. Turner, Daniel A. Dale, James Lilly +22
In the hierarchical view of star formation, giant molecular gas clouds (GMCs) undergo fragmentation to form small-scale structures made up of stars and star clusters. Here we study…
Molecular Cloud Populations in the Context of Their Host Galaxy Environments: A Multiwavelength Perspective
Jiayi Sun, Adam K. Leroy, Erik Rosolowsky +35
We present a rich, multiwavelength, multiscale database built around the PHANGS-ALMA CO(2-1) survey and ancillary data. We use this database to present the distributions of mol…
PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-Forming Galaxies
Adam K. Leroy, Eva Schinnerer, Annie Hughes +69
We present PHANGS-ALMA, the first survey to map CO J=2-1 line emission at ~1" ~ 100pc spatial resolution from a representative sample of 90 nearby (d<~20 Mpc) galaxies that lie on…
Fiery Cores: Bursty and Smooth Star Formation Distributions across Galaxy Centers in Cosmological Zoom-in Simulations
Matthew E. Orr, H Perry Hatchfield, Cara Battersby +7
We present an analysis of the kpc core regions of seven simulated Milky Way mass galaxies, from the FIRE-2 (Feedback in Realistic Environments) cosmological zoom-in…
Reproducing the CO-to-H conversion factor in cosmological simulations of Milky Way-mass galaxies
Laura C. Keating, Alexander J. Richings, Norman Murray +8
We present models of CO(1-0) emission from Milky Way-mass galaxies at redshift zero in the FIRE-2 cosmological zoom-in simulations. We calculate the molecular abundances by post-pr…
The Formation Times and Building Blocks of Milky Way-mass Galaxies in the FIRE Simulations
Isaiah B. Santistevan, Andrew Wetzel, Kareem El-Badry +5
Surveys of the Milky Way (MW) and M31 enable detailed studies of stellar populations across ages and metallicities, with the goal of reconstructing formation histories across cosmi…
The Anatomy of a Star-Forming Galaxy II: the role of FUV heating via dust
Samantha M. Benincasa, James W. Wadsley, Hugh M. P. Couchman +4
Far-Ultraviolet (FUV) radiation greatly exceeds ultraviolet, supernovae and winds in the energy budget of young star clusters but is poorly modeled in galaxy simulations. We presen…
Live Fast, Die Young: GMC lifetimes in the FIRE cosmological simulations of Milky Way-mass galaxies
Samantha M. Benincasa, Sarah R. Loebman, Andrew Wetzel +6
We present the first measurement of the lifetimes of Giant Molecular Clouds (GMCs) in cosmological simulations at , using the Latte suite of FIRE-2 simulations of Milky Way-…
Evolution of giant molecular clouds across cosmic time
David Guszejnov, Michael Y. Grudić, Stella S. R. Offner +5
Giant molecular clouds (GMCs) are well-studied in the local Universe, however, exactly how their properties vary during galaxy evolution is poorly understood due to challenging res…
A profile in FIRE: resolving the radial distributions of satellite galaxies in the Local Group with simulations
Jenna Samuel, Andrew Wetzel, Erik Tollerud +9
While many tensions between Local Group (LG) satellite galaxies and LCDM cosmology have been alleviated through recent cosmological simulations, the spatial distribution of satelli…
Star formation and ISM morphology in tidally induced spiral structures
Alex R. Pettitt, Elizabeth J. Tasker, James W. Wadsley +2
Tidal encounters are believed to be one of the key drivers of galactic spiral structure in the Universe. Such spirals are expected to produce different morphological and kinematic…
The AGORA High-Resolution Galaxy Simulations Comparison Project. II: Isolated Disk Test
Ji-hoon Kim, Oscar Agertz, Romain Teyssier +40
Using an isolated Milky Way-mass galaxy simulation, we compare results from 9 state-of-the-art gravito-hydrodynamics codes widely used in the numerical community. We utilize the in…
Effects of Galactic Disc Inclination and Resolution on Observed GMC Properties and Larson's Scaling Relations
Hsi-An Pan, Yusuke Fujimoto, Elizabeth J. Tasker +4
With ALMA making it possible to resolve giant molecular clouds (GMCs) in other galaxies, it is becoming necessary to quantify the observational bias on measured GMC properties. Usi…
The Properties of Bound and Unbound Molecular Cloud Populations Formed in Galactic Disc Simulations
Rachel L. Ward, Samantha M. Benincasa, James Wadsley +2
We explore the effect of galactic environment on properties of molecular clouds. Using clouds formed in a large-scale galactic disc simulation, we measure the observable properties…
A Superbubble Feedback Model for Galaxy Simulations
B. W. Keller, J. Wadsley, S. M. Benincasa +1
We present a new stellar feedback model that reproduces superbubbles. Superbubbles from clustered young stars evolve quite differently to individual supernovae and are substantiall…
Giant Molecular Cloud Formation in Disk Galaxies: Characterizing Simulated versus Observed Cloud Catalogues
Samantha M. Benincasa, Elizabeth J. Tasker, Ralph E. Pudritz +1
We present the results of a study of simulated Giant Molecular Clouds (GMCs) formed in a Milky Way-type galactic disk with a flat rotation curve. This simulation, which does not in…
