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…
Early-type galaxy density profiles from IllustrisTNG: II. Evolutionary trend of the total density profile
Yunchong Wang, Mark Vogelsberger, Dandan Xu +8
We study the evolutionary trend of the total density profile of early-type galaxies (ETGs) in IllustrisTNG. To this end, we trace ETGs from to and measure the power-law…
Galaxy Formation with BECDM -- II. Cosmic Filaments and First Galaxies
Philip Mocz, Anastasia Fialkov, Mark Vogelsberger +11
Bose-Einstein Condensate Dark Matter (BECDM; also known as Fuzzy Dark Matter) is motivated by fundamental physics and has recently received significant attention as a serious alter…
X-ray Signatures of Black Hole Feedback: Hot Galactic Atmospheres in IllustrisTNG and X-ray Observations
Nhut Truong, Annalisa Pillepich, Norbert Werner +6
Hot gaseous atmospheres that permeate galaxies and extend far beyond their stellar distribution, where they are commonly referred to as the circumgalactic medium (CGM), imprint imp…
Limitations to the "basic'' HOD model and beyond
Boryana Hadzhiyska, Sownak Bose, Daniel Eisenstein +2
We make use of the IllustrisTNG cosmological, hydrodynamical simulations to test fundamental assumptions of the mass-based Halo Occupation Distribution (HOD) approach to modelling…
Simulating the interstellar medium of galaxies with radiative transfer, non-equilibrium thermochemistry, and dust
Rahul Kannan, Federico Marinacci, Mark Vogelsberger +4
We present a novel framework to self-consistently model the effects of radiation fields, dust physics and molecular chemistry (H) in the interstellar medium (ISM) of galaxies.…
