Journal ArticleDOI
The stellar mass assembly of galaxies in the Illustris simulation: growth by mergers and the spatial distribution of accreted stars
Vicente Rodriguez-Gomez,Annalisa Pillepich,Laura V. Sales,Laura V. Sales,Shy Genel,Mark Vogelsberger,Qirong Zhu,Sarah Wellons,Dylan Nelson,Paul Torrey,Paul Torrey,Volker Springel,Volker Springel,Chung-Pei Ma,Lars Hernquist +14 more
TL;DR: In this article, the authors used the Illustris simulation to study the relative contributions of in situ star formation and stellar accretion to the build-up of galaxies over an unprecedentedly wide range of masses.
Journal ArticleDOI
The formation of massive, compact galaxies at z = 2 in the Illustris simulation
Sarah Wellons,Paul Torrey,Paul Torrey,Chung-Pei Ma,Vicente Rodriguez-Gomez,Mark Vogelsberger,Mariska Kriek,Pieter van Dokkum,Erica J. Nelson,Shy Genel,Shy Genel,Annalisa Pillepich,Volker Springel,Volker Springel,Debora Sijacki,Gregory F. Snyder,Dylan Nelson,Laura V. Sales,Lars Hernquist +18 more
TL;DR: In this article, the authors investigate the formation processes and quantify the assembly histories of compact galaxies in Illustris, a suite of hydrodynamical cosmological simulations encompassing a sufficiently large volume to include rare objects, while simultaneously resolving the internal structure of galaxies.
Journal ArticleDOI
The diverse evolutionary paths of simulated high-z massive, compact galaxies to z = 0
Sarah Wellons,Paul Torrey,Paul Torrey,Chung-Pei Ma,Vicente Rodriguez-Gomez,Annalisa Pillepich,Dylan Nelson,Shy Genel,Mark Vogelsberger,Lars Hernquist +9 more
TL;DR: In this paper, a sample of 35 massive, compact galaxies at z = 2 in the cosmological hydrodynamical simulation Illustris was selected to uncover their evolution and identify their descendants.
Journal ArticleDOI
Formation of high-field magnetic white dwarfs from common envelopes
TL;DR: It is shown that disk-generated fields are sufficiently strong to explain the observed range of magnetic field strengths for isolated, high-field magnetic white dwarfs and a higher-mass binary analogue may also contribute to the origin of magnetar fields.
Journal ArticleDOI
An analysis of the evolving comoving number density of galaxies in hydrodynamical simulations
Paul Torrey,Paul Torrey,Sarah Wellons,Francisco Machado,Brendan F. Griffen,Dylan Nelson,Vicente Rodriguez-Gomez,Ryan McKinnon,Annalisa Pillepich,Chung-Pei Ma,Mark Vogelsberger,Volker Springel,Volker Springel,Lars Hernquist +13 more
TL;DR: In this paper, the authors present an analysis of the evolving comoving cumulative number density of galaxy populations found in the Illustris simulation, and examine the extent to which this assumption holds in the presence of galaxy mergers or when rank ordering is broken owing to variable stellar growth rates.
