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…
Structural and photometric properties of barred galaxies from the Auriga cosmological simulations
Guillermo Blázquez-Calero, Estrella Florido, Isabel Pérez +6
In this work we analyse the structural and photometric properties of 21 barred simulated galaxies from the Auriga Project. These consist of Milky Way-mass magneto-hydrodynamical si…
Magnetising the circumgalactic medium of disk galaxies
Ruediger Pakmor, Freeke van de Voort, Rebekka Bieri +7
The circumgalactic medium (CGM) is one of the frontiers of galaxy formation and intimately connected to the galaxy via accretion of gas on to the galaxy and gaseous outflows from t…
Chemodynamics of barred galaxies in cosmological simulations: On the Milky Way's quiescent merger history and in-situ bulge
F. Fragkoudi, R. J. J. Grand, R. Pakmor +9
We explore the chemodynamical properties of a sample of barred galaxies in the Auriga magneto-hydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) bulges,…
