Arkenstone I: A Novel Method for Robustly Capturing High Specific Energy Outflows In Cosmological Simulations
Matthew C. Smith, Drummond B. Fielding, Greg L. Bryan +11
Arkenstone is a new model for multiphase, stellar feedback driven galactic winds designed for inclusion in coarse resolution cosmological simulations. In this first paper of a seri…
Code Comparison in Galaxy Scale Simulations with Resolved Supernova Feedback: Lagrangian vs. Eulerian Methods
Chia-Yu Hu, Matthew C. Smith, Romain Teyssier +8
We present a suite of high-resolution simulations of an isolated dwarf galaxy using four different hydrodynamical codes: {\sc Gizmo}, {\sc Arepo}, {\sc Gadget}, and {\sc Ramses}. A…
Two can play at that game: constraining the role of supernova and AGN feedback in dwarf galaxies with cosmological zoom-in simulations
Sophie Koudmani, Debora Sijacki, Matthew C. Smith
There is growing observational evidence for dwarf galaxies hosting active galactic nuclei (AGN), including hints of AGN-driven outflows in dwarfs. However, in the common theoretica…
The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
Aperture-corrected spectroscopic type Ia supernova host galaxy properties
Lluís Galbany, Mat Smith, Salvador Duarte Puertas +7
We use type Ia supernovae (SNe Ia) data obtained by the Sloan Digital Sky Survey-II Supernova Survey (SDSS-II/SNe) in combination with the publicly available SDSS DR16 fiber spectr…
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…
The sensitivity of stellar feedback to IMF averaging versus IMF sampling in galaxy formation simulations
Matthew C. Smith
Galaxy formation simulations frequently use Initial Mass Function (IMF) averaged feedback prescriptions, where star particles are assumed to represent single stellar populations th…
Efficient early stellar feedback can suppress galactic outflows by reducing supernova clustering
Matthew C. Smith, Greg L. Bryan, Rachel S. Somerville +4
We present a novel set of stellar feedback models, implemented in the moving-mesh code Arepo, designed for galaxy formation simulations with near-parsec (or better) resolution. The…
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…
Fast and energetic AGN-driven outflows in simulated dwarf galaxies
Sophie Koudmani, Debora Sijacki, Martin A. Bourne +1
The systematic analysis of optical large-scale surveys has revealed a population of dwarf galaxies hosting AGN, which have been confirmed by X-ray follow-up observations. Recently,…
Cosmological simulations of dwarfs: the need for ISM physics beyond SN feedback alone
Matthew C. Smith, Debora Sijacki, Sijing Shen
The dominant feedback mechanism in low mass haloes is usually assumed to take the form of massive stars exploding as supernovae (SNe). We perform very high resolution cosmological…
Supernova feedback in numerical simulations of galaxy formation: separating physics from numerics
Matthew C. Smith, Debora Sijacki, Sijing Shen
While feedback from massive stars exploding as supernovae (SNe) is thought to be one of the key ingredients regulating galaxy formation, theoretically it is still unclear how the a…
Towards the Future of Supernova Cosmology
Michelle Lochner, Bruce A. Bassett, Melvin Varughese +4
For future surveys, spectroscopic follow-up for all supernovae will be extremely difficult. However, one can use light curve fitters, to obtain the probability that an object is a…
Extending BEAMS to incorporate correlated systematic uncertainties
Michelle Lochner, Bruce A. Bassett, Melvin Varughese +4
New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the LSST will produce an unprecedented number of photometric supernova candidates, most with no spectroscopic d…
Photometric Supernova Cosmology with BEAMS and SDSS-II
Renée Hlozek, Martin Kunz, Bruce Bassett +16
Supernova cosmology without spectroscopic confirmation is an exciting new frontier which we address here with the Bayesian Estimation Applied to Multiple Species (BEAMS) algorithm…
