Galaxy interactions in IllustrisTNG-100, I: The power and limitations of visual identification
Kelly Blumenthal, Jorge Moreno, Joshua E. Barnes +6
We present a sample of 446 galaxy pairs constructed using the cosmological simulation IllustrisTNG-100 at z = 0, with M = 10-10 M. We produce…
Correlations Between Black Holes and Host Galaxies in the Illustris and IllustrisTNG Simulations
Yuan Li, Melanie Habouzit, Shy Genel +11
We study black hole - host galaxy correlations, and the relation between the over-massiveness (the distance from the average relation) of super-massive black holes (SMBH…
A study of stellar orbit fractions: simulated IllustrisTNG galaxies compared to CALIFA observations
Dandan Xu, Ling Zhu, Robert Grand +16
Motivated by the recently discovered kinematic "Hubble sequence" shown by the stellar orbit-circularity distribution of 260 CALIFA galaxies, we make use of a comparable galaxy samp…
Morphology and star formation in IllustrisTNG: the build-up of spheroids and discs
Sandro Tacchella, Benedikt Diemer, Lars Hernquist +8
Using the IllustrisTNG simulations, we investigate the connection between galaxy morphology and star formation in central galaxies with stellar masses in the range $10^9-10^{11.5}~…
Studying the Physical Properties of Tidal Features I. Extracting Morphological Substructure in CANDELS Observations and VELA Simulations
Kameswara Bharadwaj Mantha, Daniel H. McIntosh, Cody P. Ciaschi +17
The role of major mergers in galaxy evolution remains a key open question. Existing empirical merger identification methods use non-parametric and subjective visual classifications…
The Hubble Sequence at in the IllustrisTNG simulation with deep learning
M. Huertas-Company, V. Rodriguez-Gomez, D. Nelson +7
We analyze the optical morphologies of galaxies in the IllustrisTNG simulation at with a Convolutional Neural Network trained on visual morphologies in the Sloan Digital S…
Atomic and molecular gas in IllustrisTNG galaxies at low redshift
Benedikt Diemer, Adam R. H. Stevens, Claudia del P. Lagos +9
We have recently developed a post-processing framework to estimate the abundance of atomic and molecular hydrogen (HI and H2, respectively) in galaxies in large-volume cosmological…
