Extreme kinematic misalignment in IllustrisTNG galaxies: the origin, structure and internal dynamics of galaxies with a large-scale counterrotation
Sergey Khoperskov, Igor Zinchenko, Branislav Avramov +9
Modern galaxy formation theory suggests that the misalignment between stellar and gaseous components usually results from an external gas accretion and/or interaction with other ga…
The stellar halos of ETGs in the IllustrisTNG simulations: II. Accretion, merger history, and dark halo connection
C. Pulsoni, O. Gerhard, M. Arnaboldi +5
Stellar halos in early-type galaxies (ETGs) are shaped by their accretion and merger histories. We use a sample of 1114 ETGs in the TNG100 simulation with stellar masses $10^{10.3}…
The halo of M105 and its group environment as traced by planetary nebula populations: I. Wide-field photometric survey of planetary nebulae in the Leo I group
J. Hartke, M. Arnaboldi, O. Gerhard +6
M105 (NGC 3379) is an early-type galaxy in the Leo I group. This group is the nearest group that contains all main galaxy types and can thus be used as a benchmark to study the pro…
The stellar halos of ETGs in the IllustrisTNG simulations: the photometric and kinematic diversity of galaxies at large radii
C. Pulsoni, O. Gerhard, M. Arnaboldi +4
We characterize the photometric and kinematic properties of simulated early-type galaxy (ETG) stellar halos, and compare them to observations. We select a sample of ~1200 ETGs in t…
