From the archaeological point of view, the local dwarf galaxies are unique objects in which
the imprint of the conditions that shaped the early structure formation can be studied today at …

Abstract The Subaru Prime Focus Spectrograph (PFS) is a massively multiplexed fiber-fed
optical and near-infrared three-arm spectrograph (N fiber= 2400, 380≤ λ≤ 1260 nm, 1 3 …

We show that in the anticenter region, between Galactic longitudes of 110< l< 229, there is
an oscillating asymmetry in the main-sequence star counts on either side of the Galactic …

We examine the stellar haloes of the Auriga simulations, a suite of 30 cosmological
magnetohydrodynamical high-resolution simulations of Milky Way-mass galaxies performed …

We present an analysis of the large-scale structure of the halo of the Andromeda galaxy,
based on the Pan-Andromeda Archeological Survey (PAndAS), currently the most complete …

We present the widest-field resolved stellar map to date of the closest ($ D\sim 3.8$ Mpc)
massive elliptical galaxy NGC 5128 (Centaurus A; Cen A), extending out to a projected …

We analyse the merger and assembly histories of Milky Way (MW) and Andromeda (M31)-
like galaxies to quantify how, and how often, disc galaxies of this mass can survive recent …

Although the proximity of the Andromeda galaxy (M31) offers an opportunity to understand
how mergers affect galaxies, uncertainty remains about M31's most important mergers …

The detection of structures in the sky with optical surface brightnesses fainter than 30 mag
arcsec− 2 (3σ in 10× 10 arcsec boxes; r-band) has remained elusive in current photometric …

We introduce the Assembly of high-ResoluTion Eagle-simulations of MIlky Way-type
galaxieS (artemis) simulations, a new set of 42 zoomed-in, high-resolution (baryon particle …
