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.

Sagittarius: The Nearest Dwarf Galaxy [PDF]
, 1995 We have discovered a new Galactic satellite galaxy in the constellation of Sagittarius. The Sagittarius dwarf galaxy is the nearest galaxy known, subtends an angle of $> 10$ degrees on the sky, lies at a distance of $24 \kpc$ from the Sun, $\sim 16 \kpc$

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.

Pulsar‐Driven Jets in Supernovae, Gamma‐Ray Bursts, and the Universe
Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 The bipolarity of Supernova 1987A can be understood through its very early light curve from the CTIO 0.4 m telescope and IUE FES and following speckle observations of the “Mystery Spot”. These indicate a beam/jet of light/particles, with initial collimation factors >104 and velocities >0.95 c, involving up to 10−5 M⊙ interacting with circumstellar ...

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.

THE PAndAS VIEW OF THE ANDROMEDA SATELLITE SYSTEM. II. DETAILED PROPERTIES OF 23 M31 DWARF SPHEROIDAL GALAXIES [PDF]
, 2016 We present a comprehensive analysis of the structural properties and luminosities of the 23 dwarf spheroidal galaxies that fall within the footprint of the Pan-Andromeda Archaeological Survey (PAndAS). These dwarf galaxies represent the large majority of

Deep photometry of the Draco dwarf spheroidal galaxy [PDF]
The Astronomical Journal, 1986 We report the results of deep CCD photometry of two overlapping fields in the Draco dwarf spheroidal galaxy. We find (B-V)o,g = m0.69, indicating a mean [Fe/H] = −2.0. The width of the giant branch below the horizontal branch is somewhat wider than our observational errors permit, from which we infer there is a spread in metallicities amongst the Draco

Implications and Applications of Kinematic Galaxy Scaling Relations
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 Galaxy scaling relations, which describe a connection between ostensibly unrelated physical characteristics, testify to an underlying order in galaxy formation that requires understanding. I review the development of a scaling relation that (1) unites the well‐known fundamental plane (FP) relation of giant elliptical galaxies and Tully‐Fisher (TF ...

Dwarf spheroidal galaxy kinematics and spiral galaxy scaling laws [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 Los estudios cinemáticos de los satélites esferoidales enanos (dSph) de la Vía Láctea están revelando indicios tentadores sobre la estructura de los halos de materia oscura (DM) en el extremo de baja masa de la función de luminosidad de la galaxia. En el extremo brillante, el modelado de galaxias espirales ha demostrado que sus curvas de rotación son ...
