We present preliminary diameters and albedos for 7956 asteroids detected in the first year of
the NEOWISE Reactivation mission. Of those, 201 are near-Earth asteroids and 7755 are …

Context. Switchbacks are discrete angular deflections in the solar wind magnetic field that
have been observed throughout the heliosphere. Recent observations by Parker Solar …

The recent discovery of diffuse dwarf galaxies that are deficient in dark matter appears to
challenge the current paradigm of structure formation in our universe. We describe …

Aims. The aim of this work is to demonstrate that the probe-to-spacecraft potential measured
by RPW on Solar Orbiter can be used to derive the plasma (electron) density measurement …

Dwarf galaxies have been extensively studied in the Local Group, in nearby groups, and
selected clusters, giving us a robust picture of their global stellar and dynamical properties …

It was first observed in the 1970s that the dwarf galaxies surrounding our Milky Way, so-
called satellites, appear to be arranged in a thin, vast plane. Similar discoveries have been …

In the analysis of thermal infrared data of asteroids by means of thermophysical models
(TPMs) it is a common practice to neglect the uncertainty of the shape model and the …

We present the first satellite system of the Large Binocular Telescope Satellites Of Nearby
Galaxies Survey (LBT-SONG), a survey to characterize the close satellite populations of …

Context. The High Resolution Telescope (HRT) of the Polarimetric and Helioseismic Imager
on board the Solar Orbiter spacecraft (SO/PHI) and the Helioseismic and Magnetic Imager …

Context. The Metis coronagraph is one of the remote sensing instruments of the ESA-NASA
Solar Orbiter mission. The goal for the instrument is to enable the study of the solar …
