Engineering Reports, Volume 8, Issue 3, March 2026.The graphical abstract illustrates a flower classification model relying on the human visual system. The model captures images, simulates visual attention and photometric perception, extracts features of shape and color, and classifies flowers by using an optimized neural network that enhances recognition accuracy by mimicking the human eye's focusing ...

The Astrophysical Journal Supplement SeriesOur understanding of the early Universe has long been limited by biased galaxy samples selected through various color criteria. With deep JWST infrared imaging, mass-complete galaxy samples can now be studied up to z ∼ 8 for the first time.

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Classifying Astronomical Transients Using Only Host Galaxy Photometry
The Astrophysical Journal, 2023 The Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory will discover tens of thousands of extragalactic transients each night. The high volume of alerts demands immediate classification of transient types in order to prioritize ...

Astronomische Nachrichten, Volume 347, Issue 1, January 2026.ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.

The Baryonic Tully–Fisher Relation. II. Stellar Mass Models
The Astronomical JournalWe present new color–ϒ _* (mass-to-light ratio) models to convert Wide-field Infrared Survey Explorer W1 fluxes into stellar masses. We outline a range of possible star formation histories and chemical evolution scenarios to explore the confidence limits
