Disk flaring with TNG50: diversity across Milky Way and M31 analogs
Diego Sotillo-Ramos, Martina Donnari, Annalisa Pillepich +4
We use the sample of 198 Milky Way (MW) and Andromeda (M31) analogs from TNG50 to quantify the level of disk flaring predicted by a modern, high-resolution cosmological hydrodynami…
Milky Way and Andromeda analogs from the TNG50 simulation
Annalisa Pillepich, Diego Sotillo-Ramos, Rahul Ramesh +7
We present the properties of Milky Way- and Andromeda-like (MW/M31-like) galaxies simulated within TNG50, the highest-resolution run of the IllustrisTNG suite of CDM magneto-hyd…
The merger and assembly histories of Milky Way- and M31-like galaxies with TNG50: disk survival through mergers
Diego Sotillo-Ramos, Annalisa Pillepich, Martina Donnari +6
We analyze the merger and assembly histories of Milky Way (MW) and Andromeda (M31)-like galaxies to quantify how, and how often, disk galaxies of this mass can survive recent major…
Anisotropic satellite galaxy quenching modulated by supermassive black hole activity
Ignacio Martín-Navarro, Annalisa Pillepich, Dylan Nelson +4
The evolution of satellite galaxies is shaped by their constant interaction with the circum galactic medium surrounding central galaxies, which in turn may be affected by gas and e…
Quenched fractions in the IllustrisTNG simulations: the roles of AGN feedback, environment, and pre-processing
Martina Donnari, Annalisa Pillepich, Gandhali D. Joshi +8
We use the IllustrisTNG simulations to show how the fractions of quenched galaxies vary across different environments and cosmic time, and to quantify the role AGN feedback and pre…
Quenched fractions in the IllustrisTNG simulations: comparison with observations and other theoretical models
Martina Donnari, Annalisa Pillepich, Dylan Nelson +3
We make an in-depth comparison of the IllustrisTNG simulations with observational data on the quenched fractions of central and satellite galaxies, for at…
The distinct stellar-to-halo mass relations of satellite and central galaxies: insights from the IllustrisTNG simulations
Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi +9
We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodyn…
The star-formation activity of IllustrisTNG galaxies: main sequence, UVJ diagram, quenched fractions, and systematics
Martina Donnari, Annalisa Pillepich, Dylan Nelson +6
We select galaxies from the IllustrisTNG hydrodynamical simulations ( at ) and characterize the shapes and evolutions of their UVJ and star-format…
Jellyfish galaxies with the IllustrisTNG simulations: I. Gas-stripping phenomena in the full cosmological context
Kiyun Yun, Annalisa Pillepich, Elad Zinger +8
We use IllustrisTNG, a suite of gravity and MHD simulations, to study the demographics and properties of jellyfish galaxies in the full cosmological context. By jellyfish galaxies,…
The origin of the first neutron star -- neutron star merger
K. Belczynski, A. Askar, M. Arca-Sedda +8
The first neutron star-neutron star (NS-NS) merger was discovered on August 17, 2017 through gravitational waves (GW170817) and followed with electromagnetic observations. This mer…
Massive black holes interactions during the assembly of heavy sub-structures in the centre of galaxy clusters
M. Donnari, M. Arca-Sedda, M. Merafina
We performed a series of direct N-body simulations with the aim to follow the dynamical evolution of a galaxy cluster (GC) () in different environ…
Can dark energy explain the observed outflow in galaxy clusters?
M. Donnari, M. Arca-Sedda, M. Merafina
Recent observations of the Virgo cluster and the Local Group suggested that some galaxies are flowing out from their parent cluster. This may be the signature that dark energy (DE)…
Formation and evolution of heavy sub-structures in the centre of galaxy clusters: the local effect of dark energy
Manuel Arca Sedda, Martina Donnari, Marco Merafina
We discuss how the centres of galaxy clusters evolve in time, showing the results of a series of direct N-body simulations. In particular, we followed the evolution of a galaxy clu…
The local effect of Dark Energy in galaxy clusters
Martina Donnari, Marco Merafina, Manuel Arca-Sedda
Recently, observational data and high precision mapping of the local velocity field of Local Group and Virgo cluster have revealed a linear velocity-distance relation of the outerm…
Galaxy clusters in presence of dark energy: a kinetic approach
Marco Merafina, Gennady S. Bisnovatyi-Kogan, Martina Donnari
Context. The external regions of galaxy clusters may be under strong influence of the dark energy, discovered by observations of the SN Ia at redshift z < 1. Aims. The presence of…
