The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

We present the neutral gas morphology of four galaxies from z = 0.22 to 0.47 obtained with the COSMOS H i Large Extragalactic Survey (CHILES). The H i is resolved at the highest redshift with the 7 $\mathop{.}\limits^{\unicode{x02033}}$ 5 beam of CHILES ...

We present the results of 0.″6-resolution observations of CO J = 3 − 2 line emission in 10 massive star-forming galaxies at z ∼ 2.2–2.5 with the Atacama Large Millimeter/submillimeter Array (ALMA).

Two Micron‐Size Dark Dimensions
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

The visibility of high-redshift galaxies [PDF]
The most visible galaxies (those which have the largest apparent sizes and isophotal luminosities when seen at a given distance) are those with a particular observed surface brightness. Extending this argument to high-redshift galaxies, it is clear that this optimum surface brightness moves progressively to brighter intrinsic surface brightnesses, so ...

We present detections of auroral emission lines of [O iii ], [O ii ], [S iii ], and [S ii ] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at z = 1.4–7.2 from the AURORA survey.

ABSTRACT Classification of galaxies, stars, and quasars using spectral data is fundamental to astronomy, but often relies heavily on redshift. This study evaluates the performance of 10 machine learning algorithms on SDSS data to classify these objects, with a particular focus on scenarios where redshift information is unavailable.
