Towards convergence of turbulent dynamo amplification in cosmological simulations of galaxies

Sergio Martin-Alvarez, Julien Devriendt, Adrianne Slyz +3

Our understanding of the process through which magnetic fields reached their observed strengths in present-day galaxies remains incomplete. One of the advocated solutions is a turb…

Simulating gas kinematic studies of high-redshift galaxies with the HARMONI Integral Field Spectrograph

Mark L. A. Richardson, Laurence Routledge, Niranjan Thatte +4

We present simulated observations of gas kinematics in galaxies formed in 10 pc resolution cosmological simulations with the hydrodynamical + N-body code RAMSES, using the new RAMS…

Challenges and Techniques for Simulating Line Emission

Karen P. Olsen, Andrea Pallottini, Aida Wofford +9

Modeling emission lines from the millimeter to the UV and producing synthetic spectra is crucial for a good understanding of observations, yet it is an art filled with hazards. Thi…

Thermal History Of Cbb Chondrules And Cooling Rate Distributions Of Ejecta Plumes

R. H. Hewins, C. Condie, M. Morris +3

It has been proposed that some meteorites, CB and CH chondrites, contain material formed as a result of a protoplanetary collision during accretion. Their melt droplets (chondrules…

The impact of baryons on the matter power spectrum from the Horizon-AGN cosmological hydrodynamical simulation

Nora Elisa Chisari, Mark L. A. Richardson, Julien Devriendt +7

Accurate cosmology from upcoming weak lensing surveys relies on knowledge of the total matter power spectrum at percent level at scales /Mpc, for which modelling the im…

Using Real and Simulated Measurements of the Thermal Sunyaev-Zel'dovich Effect to Constrain Models of AGN Feedback

Alexander Spacek, Mark Richardson, Evan Scannapieco +4

Energetic feedback from active galactic nuclei (AGNs) is often used in simulations to resolve several outstanding issues in galaxy formation, but its impact is still not fully unde…

Cosmic evolution of stellar quenching by AGN feedback: clues from the Horizon-AGN simulation

R. S. Beckmann, J. Devriendt, A. Slyz +8

The observed massive end of the galaxy stellar mass function is steeper than its predicted dark matter halo counterpart in the standard CDM paradigm. In this paper, we investiga…

Comparing Simulations of AGN Feedback

Mark L. A. Richardson, Evan Scannapieco, Julien Devriendt +5

We perform adaptive mesh refinement (AMR) and smoothed particle hydrodynamics (SPH) cosmological zoom simulations of a region around a forming galaxy cluster, comparing the ability…

Galactic winds and stellar populations in Lyman emitting galaxies at z ~ 3.1

Emily M. McLinden, James E. Rhoads, Sangeeta Malhotra +4

We present a sample of 33 spectroscopically confirmed z ~ 3.1 Ly-emitting galaxies (LAEs) in the Cosmological Evolution Survey (COSMOS) field. This paper details the narrow-band…

High-Redshift Galaxies with Large Ionization Parameters

Mark L. A. Richardson, Emily M. Levesque, Emily M. McLinden +3

Motivated by recent observations of galaxies dominated by emission lines, which show evidence of being metal poor with young stellar populations, we present calculations of multipl…

[NeIII]/[OII] as an Ionization Parameter Diagnostic in Star-Forming Galaxies

Emily M. Levesque, Mark L. A. Richardson

We present our parameterizations of the log([NeIII]3869/[OII]3727) (Ne3O2) and log([OIII]5007/[OII]3727) ratios as comparable and effective diagnostics of ionization parameter in s…

Formation of Compact Clusters from High Resolution Hybrid Cosmological Simulations

Mark L. A. Richardson, Evan Scannapieco, William J. Gray

The early Universe hosted a large population of small dark matter `minihalos' that were too small to cool and form stars on their own. These existed as static objects around larger…

Hybrid Cosmological Simulations with Stream Velocities

Mark L. A. Richardson, Evan Scannapieco, Robert J. Thacker

In the early universe, substantial relative "stream" velocities between the gas and dark matter arise due to radiation pressure and persist after recombination. To asses the impact…

The Dynamical Masses, Densities, and Star Formation Scaling Relations of Lyman Alpha Galaxies

James E. Rhoads, Sangeeta Malhotra, Steven L. Finkelstein +4

We present the first dynamical mass measurements for Lyman alpha galaxies at high redshift, based on velocity dispersion measurements from rest-frame optical emission lines and siz…

Power spectrum for the small-scale Universe

Lawrence M. Widrow, Pascal J. Elahi, Robert J. Thacker +2

The first objects to arise in a cold dark matter universe present a daunting challenge for models of structure formation. In the ultra small-scale limit, CDM structures form nearly…

Predictions of Quasar Clustering: Redshift, Luminosity and Selection Dependence

Robert J. Thacker, Evan Scannapieco, H. M. P. Couchman +1

We show that current clustering observations of quasars and luminous AGN can be explained by a merger model augmented by feedback from outflows. Using numerical simulations large e…
