The Stellar Content of the Nuclei of Spiral Galaxies [PDF]
Highlights of Astronomy, 1980 Widened, image-tube spectra at a dispersion of 120 Å mm-1 were obtained of the nuclei of 36 spiral (Shapley-Ames) galaxies. Spectral features in the region λλ 3800 - 4300 Å were used to assign a spectral index to each galaxy and to estimate the luminosity classes of the stars contributing the majority of the light at these wavelengths. Bulge magnitudes

STELLAR, GAS, AND DARK MATTER CONTENT OF BARRED GALAXIES [PDF]
The Astrophysical Journal, 2017 ABSTRACT We select a sample of galaxies from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) where galaxies are classified, through visual inspection, as hosting strong bars, weak bars, or as unbarred galaxies, and make use of H i mass and kinematic information from the Arecibo Legacy Fast ALFA survey catalog, to study the stellar,

The Stellar Content of the Local Group Dwarf Galaxy Phoenix
The Astronomical Journal, 1999 We present new deep $VI$ ground-based photometry of the Local Group dwarf galaxy Phoenix. Our results confirm that this galaxy is mainly dominated by red stars, with some blue plume stars indicating recent (100 Myr old) star formation in the central part of the galaxy.

Advanced Healthcare Materials, EarlyView.Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Facile Bottom‐Up Assembly of Photonic Micropatterns via Surface‐Guided Colloidal Crystallization
Advanced Materials, EarlyView.High‐resolution photonic micropatterns with vivid structural colors are fabricated through bottom‐up assembly, guided by surface‐dependent regioselective heterogeneous nucleation and crystal growth of colloidal particles. Full‐spectrum color tunability is achieved by controlling particle size and interparticle attraction, while in situ color mixing is ...

Versatile Gasochromic Hydrogen Detection via Supraparticle‐Based Applied Composite Materials
Advanced Optical Materials, EarlyView.Silica‐platinum‐resazurin supraparticles are embedded into PMMA to form suprabeads and thin films. The thereby obtained indicators change color from purple to pink to colorless on hydrogen exposure. The indicator systems are tested under various environmental conditions, and their performance is related to their microscopically visualized structure ...
