The Tucana dwarf spheroidal galaxy: not such a massive failure after all [PDF]
Astronomy & Astrophysics, 2020 Context. Isolated local group (LG) dwarf galaxies have evolved most or all of their life unaffected by interactions with the large LG spirals and therefore offer the opportunity to learn about the intrinsic characteristics of this class of objects. Aims.

The bursty star formation history of the Fornax dwarf spheroidal galaxy revealed with the HST [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We present a new derivation of the star formation history (SFH) of the dSph galaxy Fornax in two central regions, characterized by unprecedented precision and age resolution.

Searching for light in the darkness: Bounds on ALP dark matter with the optical MUSE-faint survey
Physics Letters B, 2021 We use MUSE spectroscopic observations of the dwarf spheroidal galaxy Leo T between 470 and 935 nm to search for radiative decays of axion like particles (ALPs).

Laboratory exploration of mineral precipitates from Europa's subsurface ocean
Journal of Applied Crystallography, Volume 54, Issue 5, Page 1455-1479, October 2021., 2021 Precipitation experiments from a model Europan ocean solution subjected to fast and slow freezing suggest that the highly hydrated Na–Mg sulfate phase Na2Mg(SO4)2·16H2O is one of the lowest‐temperature mineral phases likely to be stable on Europa's surface and may therefore be astrobiologically significant.The precipitation of hydrated phases from a ...

A Deep View into the Nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. I. Data and Stellar Population Characterization [PDF]
Astrophysical Journal, 2019 The center of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) hosts a nuclear star cluster (NSC), M54, which is the only galaxy nucleus that can be resolved into individual stars at optical wavelengths.

Journal of Geophysical Research: Planets, Volume 126, Issue 5, May 2021., 2021 Abstract The origin of the interstellar object 1I/‘Oumuamua has defied explanation. In a companion paper (Jackson & Desch, 2021), we show that a body of N2 ice with axes 45 m × 44 m × 7.5 m at the time of observation would be consistent with its albedo, nongravitational acceleration, and lack of observed CO or CO2 or dust.

Annihilating dark matter search with 12 years of Fermi LAT data in nearby galaxy clusters
SciPost Physics Proceedings, 2023 Galaxy clusters contain an abundance of dark matter making them attractive laboratories for indirect DM searches. This work details a search for signals of pair annihilation from WIMP dark matter in the GeV gamma ray regime.

VLT/FLAMES high-resolution chemical abundances in Sculptor: a textbook dwarf spheroidal galaxy [PDF]
Astronomy & Astrophysics, 2018 We present detailed chemical abundances for 99 red-giant branch stars in the centre of the Sculptor dwarf spheroidal galaxy, which have been obtained from high-resolution VLT/FLAMES spectroscopy.
