Where are the extremely metal-poor stars in the Milky Way and Andromeda? Expectations from TNG50
Li-Hsin Chen, Annalisa Pillepich, Simon C. O. Glover +1
We analyse the location of extremely metal-poor stars (EMPs, [Fe/H]) in 198 Milky Way (MW)/M31-like galaxies at in the TNG50 simulation. Each system is divided into fo…
MaNGIA: 10,000 mock galaxies for stellar population analysis
Regina Sarmiento, Marc Huertas-Company, Johan H. Knapen +4
Modern astronomical observations give unprecedented access to the physical properties of nearby galaxies, including spatially resolved stellar populations. However, observations ca…
Feedback reshapes the baryon distribution within haloes, in halo outskirts, and beyond: the closure radius from dwarfs to massive clusters
Mohammadreza Ayromlou, Dylan Nelson, Annalisa Pillepich
We explore three sets of cosmological hydrodynamical simulations, IllustrisTNG, EAGLE, and SIMBA, to investigate the physical processes impacting the distribution of baryons in and…
The survival of stellar discs in Fornax-like environments, from TNG50 to real galaxies
Pablo M. Galán-de Anta, M. Sarzi, A. Pillepich +14
We study the evolution of kinematically-defined stellar discs in 10 Fornax-like clusters identified in the TNG50 run from the IllustrisTNG suite of cosmological simulations. We con…
iMaNGA: mock MaNGA galaxies based on IllustrisTNG and MaStar SSPs -- II. The catalogue
Lorenza Nanni, Daniel Thomas, James Trayford +8
Strengthening the synergy between simulations and observations is essential to test galaxy formation and evolution theories. To achieve this goal, in the first paper of this series…
Line Emission Mapper (LEM): Probing the physics of cosmic ecosystems
Ralph Kraft, Maxim Markevitch, Caroline Kilbourne +107
The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe's structure formation. It will also provide transformative…
