Galaxies with Shells in the Illustris Simulation: Metallicity Signatures
Ana-Roxana Pop, Annalisa Pillepich, Nicola C. Amorisco +1
Stellar shells are low surface brightness arcs of overdense stellar regions, extending to large galactocentric distances. In a companion study, we identified 39 shell galaxies in a…
The Size Evolution of Star-forming and Quenched Galaxies in the IllustrisTNG simulation
Shy Genel, Dylan Nelson, Annalisa Pillepich +8
We analyze scaling relations and evolution histories of galaxy sizes in TNG100, part of the IllustrisTNG simulation suite. Observational qualitative trends of size with stellar mas…
The uniformity and time-invariance of the intra-cluster metal distribution in galaxy clusters from the IllustrisTNG simulations
Mark Vogelsberger, Federico Marinacci, Paul Torrey +8
The distribution of metals in the intra-cluster medium encodes important information about the enrichment history and formation of galaxy clusters. Here we explore the metal conten…
Offsets between member galaxies and dark matter in clusters: a test with the Illustris simulation
Karen Y. Ng, Annalisa Pillepich, David Wittman +3
Dark matter with a non-zero self-interacting cross section () has been posited as a solution to a number of outstanding astrophysical mysteries. Many studies of mergi…
The bispectrum of redshifted 21-cm fluctuations from the dark ages
Annalisa Pillepich, Cristiano Porciani, Sabino Matarrese
Brightness-temperature fluctuations in the redshifted 21-cm background from the cosmic dark ages are generated by irregularities in the gas-density distribution and can then be use…
