Versatile Gasochromic Hydrogen Detection via Supraparticle‐Based Applied Composite Materials
Advanced Optical Materials, Volume 14, Issue 9, 6 March 2026.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 ...

On the Significance of the Thick Disks of Disk Galaxies
The Astrophysical Journal Supplement SeriesThick disks are a prevalent feature observed in numerous disk galaxies, including our own Milky Way. Their significance has been reported to vary widely, ranging from a few percent to 100% of the disk mass, depending on the galaxy and the measurement ...

The molecular and atomic hydrogen gas content of the Boötes Void galaxy CG 910
Astronomy & AstrophysicsContext. Void galaxies are located in the most under-dense environments of the Universe, where the number density of galaxies is extremely low. They are, hence, good targets for studying the secular evolution of galaxies and the slow buildup of stellar ...

On the limits of measuring the bulge and disk properties of local and high-redshift massive galaxies
, 2016 A considerable fraction of the massive quiescent galaxies at \emph{z} $\approx$ 2, which are known to be much more compact than galaxies of comparable mass today, appear to have a disk.

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, Volume 13, Issue 15, 13 March 2026.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Conditions for Bar Formation in Bulgeless Disk Galaxies
The Astrophysical JournalWhile bars are commonly observed in disk galaxies, the precise conditions governing their formation remain incompletely understood. To investigate these conditions, we perform a suite of N -body simulations of bulgeless disk galaxies with stellar masses ...

Galaxies, 2015 I discuss my latest observational data and ideas about decoupled gaseous subsystems in nearby lenticular galaxies. As an extreme case of inclined gaseous disks, I demonstrate a sample of inner polar disks, derive their incidence, about 10% among the ...

The Milky Way as a High Redshift Galaxy: The Importance of Thick Disk Formation in Galaxies
, 2014 We compare the star-formation history and dynamics of the Milky Way (MW) with the properties of distant disk galaxies. During the first ~4 Gyr of its evolution, the MW formed stars with a high star-formation intensity (SFI), Sigma_SFR~0.6 Msun/yr/kpc2 ...

What determines the bulge to disk ratio of galaxies [PDF]
Galaxies having the same luminosity may have very different bulge to disk ratios, while the mean bulge to disk ratio slowly increases with total luminosity (Schecter and Dressler, 1987, Sandage et al., 1985).
