Planes of satellites, no longer in tension with LCDM
Laura V. Sales, Julio F. Navarro
The arrangement of dwarf galaxies in a thin plane surrounding the Milky Way has been thought to contradict the prevailing cosmological model of cold dark matter in the Universe. Ne…
Snowmass2021 Cosmic Frontier White Paper: Cosmological Simulations for Dark Matter Physics
Arka Banerjee, Kimberly K. Boddy, Francis-Yan Cyr-Racine +15
Over the past several decades, unexpected astronomical discoveries have been fueling a new wave of particle model building and are inspiring the next generation of ever-more-sophis…
The Formation of Ultra-Diffuse Galaxies in Clusters
Laura V. Sales, Julio F. Navarro, Louis Penafiel +3
We use the IllustrisTNG cosmological hydrodynamical simulation to study the formation of ultra-diffuse galaxies (UDGs) in galaxy clusters. We supplement the simulations with a real…
The effect of dark matter-dark radiation interactions on halo abundance -- a Press-Schechter approach
Omid Sameie, Andrew J. Benson, Laura V. Sales +3
We study halo mass functions with the Press-Schechter formalism for interacting dark matter models, where matter power spectra are damped due to dark acoustic oscillations in the e…
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…
Satellite abundances around bright isolated galaxies II: radial distribution and environmental effects
Wenting Wang, Laura V. Sales, Bruno M. B. Henriques +1
We use the SDSS/DR8 galaxy sample to study the radial distribution of satellite galaxies around isolated primaries, comparing to semi-analytic models of galaxy formation based on t…
The shape of dark matter subhalos in the Aquarius simulations
Carlos Vera-Ciro, Laura V. Sales, Amina Helmi +1
We analyze the Aquarius simulations to characterize the shape of dark matter halos with peak circular velocity in the range 8<Vmax<200 km/s, and perform a convergence study using t…
Counterrotating Stars in Simulated Galaxy Disks
David G. Algorry, Julio F. Navarro, Mario G. Abadi +3
Counterrotating stars in disk galaxies are a puzzling dynamical feature whose origin has been ascribed to either satellite accretion events or to disk instabilities triggered by de…
Stellar feedback by radiation pressure and photoionization
Laura V. Sales, Federico Marinacci, Volker Springel +1
The relative impact of radiation pressure and photoionization feedback from young stars on surrounding gas is studied with hydrodynamic radiative transfer (RT) simulations. The cal…
Satellites and Haloes of Dwarf Galaxies
Laura V. Sales, Wenting Wang, Simon D. M. White +1
We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mai…
Dark satellites and the morphology of dwarf galaxies
Amina Helmi, L. V. Sales, E. Starkenburg +4
One of the strongest predictions of the LambdaCDM cosmological model is the presence of dark satellites orbiting all types of galaxies. We focus here on the dynamical effects of su…
The Origin of Disks and Spheroids in Simulated Galaxies
Laura V. Sales, Julio F. Navarro, Tom Theuns +5
In the simplest scenario, disk galaxies form predominantly in halos with high angular momentum and quiet recent assembly history, whereas spheroids are the slowly-rotating remnants…
The dark matter halos of dwarf galaxies: a challenge for the LCDM paradigm?
Ismael Ferrero, Mario G. Abadi, Julio F. Navarro +2
The cold dark matter halo mass function is much steeper than the galaxy stellar mass function on galactic and subgalactic scales. This difference is usually reconciled by assuming…
The Shape of Dark Matter Haloes in the Aquarius Simulations: Evolution and Memory
Carlos A. Vera-Ciro, Laura V. Sales, Amina Helmi +5
We use the high resolution cosmological N-body simulations from the Aquarius project to investigate in detail the mechanisms that determine the shape of Milky Way-type dark matter…
Feedback and the Structure of Simulated Galaxies at redshift z=2
Laura V. Sales, Julio F. Navarro, Joop Schaye +3
We study the properties of simulated high-redshift galaxies using cosmological N-body/gasdynamical runs from the OverWhelmingly Large Simulations (OWLS) project. The runs contrast…
Disk galaxies at z=2 in OWLS
Julio F. Navarro, Laura V. Sales, Joop Schaye +2
We use the OWLS (OverWhelmingly Large Simulations) set of cosmological Nbody/gasdynamical simulations to study the properties of simulated galaxies at z=2. We focus on the effect o…
The Origin of Extended Disk Galaxies at z=2
Laura V. Sales, Julio F. Navarro, Joop Schaye +4
Galaxy formation models typically assume that the size and rotation speed of galaxy disks are largely dictated by the mass, concentration, and spin of their surrounding dark matter…
