ABSTRACT The Panchromatic Hubble Andromeda Treasury is an ongoing Hubble Space
Telescope Multi-Cycle Treasury program to image∼ 1/3 of M31's star-forming disk in six …

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 …

It has been suggested that radio telescopes may be sensitive to axion dark matter that
resonantly converts to radio photons in the magnetospheres surrounding neutron stars …

The existence of mutually correlated thin and rotating planes of satellite galaxies around
both the Milky Way (MW) and Andromeda (M31) calls for an explanation. Previous work in …

ABSTRACT We use the Panchromatic Hubble Andromeda Treasury survey data set to
perform spatially resolved measurements of star cluster formation efficiency (Γ), the fraction …

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 lambda-cold …

We present spectroscopic data for 180 red giant branch (RGB) stars in the isolated dwarf
irregular galaxy Wolf–Lundmark–Mellote (WLM). Observations of the calcium II triplet lines in …

Ultralight axion-like particles ma∼ 10− 22 eV, or Fuzzy Dark Matter (FDM), behave
comparably to cold dark matter (CDM) on cosmological scales and exhibit a kpc-size de …

We present a detailed kinematic analysis of the outer halo globular cluster system of the
Andromeda galaxy (M31). Our basis for this is a set of new spectroscopic observations for 78 …

The stellar kinematics of galactic disks are key to constraining disk formation and evolution
processes. In this paper, for the first time, we measure the stellar age–velocity dispersion …
