H i Gas and Star Formation in Major Galaxy Pairs from the FAST All Sky H i Survey (FASHI)

The Astrophysical Journal
Atomic hydrogen (H i ) plays a fundamental role in fueling star formation in galaxies. However, the behavior of H i gas in interacting systems, particularly galaxy pairs, remains elusive.

How Many Worlds Could There Be? David Lewis and Advanced Modalizing

Analytic Philosophy, EarlyView.
ABSTRACT Advanced modalizing, namely, possibilities and necessities concerning modal space itself, is problematic for a Lewis‐style analysis of modality. A popular solution, proposed by Divers, postulates explicit semantic clauses for a collapse of advanced modalizing, to the conclusion that all such matters are, if true in the first place, both ...

Visual Icons

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT Philosophers often characterize perception as image‐like. There is little agreement, however, about what constitutes an imagistic or iconic representation. This article identifies five signature properties of iconic representations endorsed in the philosophical and scientific literature: item‐richness, feature‐richness, spatiotemporal ...

BerryBox: An affordable computer vision system for postharvest phenotyping of cranberry and other small fruits

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Fruit size, shape, color, and percent fruit rot are important quality traits for breeding cranberry (Vaccinium macrocarpon Ait.). Image analysis can be used to measure these traits, but affordable hardware for standardized image capture and integrated user‐friendly software pipelines are lacking.

Living with Neighbors. V. Better-aligned Spiral+Spiral Galaxy Pairs Show Stronger Star Formation

The Astrophysical Journal
Enhanced star formation (SF) with star-forming neighboring galaxies bolsters the hydrodynamical contributions during paired interactions. Although the relative spin orientation between interacting galaxies can influence this effect, it has not been ...

Serendipitous Discovery of Short Peptides Dimethylammonium Salt Promoting Neural Differentiation

Journal of Peptide Science, Volume 32, Issue 10, October 2026.
Design and synthesis of new heptapeptides exhibiting significant neuroprotection and structure–activity relationship (SAR) insights to guide the development of bioactive peptides. ABSTRACT The synthesis and in vitro neuronal growth support activity of a novel series of heptapeptides (1–19) are reported here. Structural studies of the peptide 3 (LSAVTFG.

The molecular gas content throughout the low-z merger sequence

The Open Journal of Astrophysics
Exploiting IRAM 30 m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50\%, a mildly increased CO excitation, and standard molecular-to-atomic gas ratios, compared to non-interacting ...

Cosmic Radiation Dose‐Rates for Civil Aviation in the Middle East: Vertical Structure, Solar Modulation, and Comparison With Models

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract High‐altitude balloon measurements were conducted over southern Israel (30°35′N, 34°45′E; 850 m a.s.l., geomagnetic rigidity cutoff 10.3 GV) to characterize the vertical profiles of atmospheric ionization and radiation up to ∼35 km. Six balloon launches between October 2014 and August 2016 recorded the variability of atmospheric ionization ...

Living with Neighbors. VI. Unraveling the Dual Impact of Bars on Star Formation in Paired Galaxies Using DESI

The Astrophysical Journal
We present a comprehensive investigation into the influence of stellar bars on star formation (SF) in galaxy pairs, using a large sample of low-redshift galaxies (0.02 < z < 0.08) from the DESI Legacy Imaging Surveys Data Release 8. Our analysis examines

Dynamics of Galaxy Interactions [PDF]

, 1998
This review briefly and very informally summarizes some of my ongoing research. One unifying theme in my work is the use of computers to bridge the gap between human and astronomical time-scales. Galactic collisions are an example; the dynamics of interacting galaxies can be visualized with numerical simulations.
