Cold dark matter (CDM) simulations predict a central cusp in the mass distribution of galaxies. This prediction is in stark contrast with observations of dwarf galaxies that show a central plateau or "core" in their density distribution. The proposed solutions to this core-cusp problem can be classified into two types. One invokes feedback

We present the discovery and characterisation of the post-common-envelope central star system in the planetary nebula PN G283.7-05.1. Deep images taken as part of the POPIPlaN survey indicate that the nebula may possess a bipolar morphology similar to other post-common-envelope planetary nebulae. Simultaneous light and radial velocity curve

Aims: This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the Sun from outside the Sun-Earth line. It is the key instrument meant to address the top-level science question: How does the solar dynamo work and drive connections between

In 2033, after a 12-year trip across the Solar System, NASA's Lucy mission will arrive at the Patroclus─Menoetius binary system, in Jupiter's L5 cloud. On its way, Lucy will visit one asteroid and seven Jupiter Trojans, all of them primitive asteroids. Lucy's foreseen discoveries about the surface geology, color, and composition of these Trojans

The Herschel Extragalactic Legacy Project (HELP) focused on the data from ESA's Herschel} mission, which covered around 1300~$\rm deg^2$ on the sky. HELP systematically combines data from 23 of the premier extragalactic survey fields. It compiles all the ancillary data that are available across the HELP fields into a catalogue with consistent

Massive sets of stellar spectroscopic observations are rapidly becoming available and these can be used to determine the chemical composition and evolution of the Galaxy with unprecedented precision. One of the major challenges in this endeavour involves constructing realistic models of stellar spectra with which to reliably determine stellar
