Molecular hydrogen in IllustrisTNG galaxies: carefully comparing signatures of environment with local CO & SFR data
Adam R. H. Stevens, Claudia del P. Lagos, Luca Cortese +7
We examine how the post-processed content of molecular hydrogen (H) in galaxies from the TNG100 cosmological, hydrodynamic simulation changes with environment at , ass…
Inferring the Morphology of Stellar Distribution in TNG50: Twisted and Twisted-Stretched shapes
Razieh Emami, Lars Hernquist, Charles Alcock +9
We investigate the morphology of the stellar distribution in a sample of Milky Way (MW) like galaxies in the TNG50 simulation. Using a local in shell iterative method (LSIM) as the…
A tidally induced global corrugation pattern in an external disc galaxy similar to the Milky Way
Facundo A. Gómez, Sergio Torres-Flores, Catalina Mora-Urrejola +11
We study the two dimensional (2D) line-of-sight velocity () field of the low-inclination, late-type galaxy VV304a. The resulting 2D kinematic map reveals a global, coh…
An off-centred bulge or a satellite? Hydrodynamical -body simulations of the disc galaxy NGC 5474
R. Pascale, M. Bellazzini, M. Tosi +3
We present dynamical models of the star-forming galaxy NGC 5474 based on -body hydrodynamical numerical simulations. We investigate the possible origin of the compact round stel…
Revisiting the tension between fast bars and the CDM paradigm
Francesca Fragkoudi, Robert J. J. Grand, Ruediger Pakmor +5
The pattern speed with which galactic bars rotate is intimately linked to the amount of dark matter in the inner regions of their host galaxies. In particular, dark matter haloes a…
Coordinated Assembly of Galaxy Groups and Clusters in the IllustrisTNG Simulations
Meng Gu, Charlie Conroy, Benedikt Diemer +6
Recent stellar population analysis of early-type galaxy spectra has demonstrated that the low-mass galaxies in cluster centers have high [] and old ages characteristic of…
