The Gaia mission has revolutionized our view of the Milky Way and its satellite citizens. The
field of Galactic Archaeology has been piecing together the formation and evolution of the …

Recent discoveries of a significant population of bright galaxies at cosmic dawn $\left
(z\gtrsim 10\right) $ have enabled critical tests of cosmological galaxy formation models. In …

Both observations and simulations have shown strong evidence for highly time-variable star
formation in low-mass and/or high-redshift galaxies, which has important observational …

We introduce the new TNG-Cluster project, an addition to the IllustrisTNG suite of
cosmological magnetohydrodynamical simulations of galaxy formation. Our objective is to …

Anomalously high nitrogen-to-oxygen abundance ratios [N/O] are observed in globular
clusters (GCs), among the field stars of the Milky Way (MW), and even in the gas in az≈ 11 …

We present an extended suite of the Auriga cosmological gravo-magnetohydrodynamical
'zoom-in'simulations of 40 Milky Way-mass haloes and 26 dwarf galaxy–mass haloes run …

We present a new scheme for the classification of the in-situ and accreted globular clusters
(GCs). The scheme uses total energy E and z-component of the orbital angular momentum …

Over the last few years, many studies have found an empirical relationship between the
abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 …

Dark sector theories naturally lead to multicomponent scenarios for dark matter where a
subcomponent can dissipate energy through self-interactions, allowing it to efficiently cool …

We study the kinematics of stars both at their formation and today within 14 Milky Way (MW)-
mass galaxies from the FIRE-2 cosmological zoom-in simulations. We quantify the relative …
