Evidence for multiple crossings and stripping of Gaia-Enceladus/Sausage across the Milky Way
Astronomy & AstrophysicsContext. The accretion of Gaia-Enceladus/Sausage (GES) onto the Milky Way (MW) is one of the most prominent features of the Galactic halo revealed by the combination of the Gaia satellite and large spectroscopic surveys.

The “Building Blocks” of Stellar Halos
Galaxies, 2017 The stellar halos of galaxies encode their accretion histories. In particular, the median metallicity of a halo is determined primarily by the mass of the most massive accreted object.

The Astrophysical Journal Letters, 2023 The quenched fraction of satellite galaxies is aligned with the orientation of the halo’s central galaxy, such that on average, satellites form stars at a lower rate along the major axis of the central.

, 2011 Some of the extremely metal-poor Blue Compact Dwarf galaxies (XBCDs) in the nearby universe form galaxy pairs with remarkably similar properties. This fact points to an intriguing degree of synchronicity in the formation history of these binary dwarf ...

Galaxy formation in the Planck cosmology – I. Matching the observed evolution of star formation rates, colours and stellar masses [PDF]
, 2014 We have updated the Munich galaxy formation model to the Planck first-year cosmology, while modifying the treatment of baryonic processes to reproduce recent data on the abundance and passive fractions of galaxies from z = 3 down to z = 0. Matching these

Advanced Materials, EarlyView.A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution
Universe, 2022 Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do
