PROTEOMICS, Volume 24, Issue 12-13, June 2024.Abstract MALDI mass spectrometry imaging (MALDI imaging) uniquely advances cancer research, by measuring spatial distribution of endogenous and exogenous molecules directly from tissue sections. These molecular maps provide valuable insights into basic and translational cancer research, including tumor biology, tumor microenvironment, biomarker ...

Are Nuclear Star Clusters the Precursors of Massive Black Holes?
Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 We present new upper limits for black hole masses in extremely late type spiral galaxies. We confirm that this class of galaxies has black holes with masses less than 106M⊙, if any. We also derive new upper limits for nuclear star cluster masses in massive galaxies with previously determined black hole masses.

Zinc abundances in the Sculptor dwarf spheroidal galaxy, [PDF]
Astronomy & Astrophysics, 2017 From ESO VLT/FLAMES/GIRAFFE spectra, abundance measurements of Zn have been made in ≈100 individual red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy. This is the largest sample of individual Zn abundance measurements within a stellar system beyond the Milky Way.

Updated Bounds on Axion‐Like Particle Dark Matter with the Optical MUSE‐Faint Survey
Annalen der Physik, Volume 536, Issue 1, January 2024.This study presents bounds on the axion‐like particle (ALP) to two‐photon coupling in the mass range $2.65‐5.27$ eV. The signal from ALP decay are sought in the Multi Unit Spectroscopic Explorer (MUSE) observations of five dwarf spheroidal galaxies, under the assumption that ALPs make up the whole dark matter.

Radio-Frequency Searches for Dark Matter in Dwarf Galaxies
Galaxies, 2019 Dwarf spheroidal galaxies have long been discussed as optimal targets for indirect dark matter searches. However, the majority of such studies have been conducted with gamma-ray instruments.

Journal of High Energy Physics, 2020 In hidden sector models, dark matter does not directly couple to the particle content of the Standard Model, strongly suppressing rates at direct detection experiments, while still allowing for large signals from annihilation.

Dwarf elliptical galaxies: United and divided
, 2015 Although of humble appearance and often overlooked because of their modest physical sizes and low star densities, dwarf elliptical (dE) galaxies revealed themselves as the most common type of galaxies to exist in the Universe today.

Extreme Tidal Stripping May Explain the Overmassive Black Hole in Leo I: A Proof of Concept
The Astrophysical Journal Letters, 2023 A recent study found dynamical evidence of a supermassive black hole of ∼3 × 10 ^6 M _⊙ at the center of Leo I, the most distant dwarf spheroidal galaxy of the Milky Way. This black hole, comparable in mass to the Milky Way’s Sgr A*, places the system >2
