Journal of Raman Spectroscopy, EarlyView.Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

International Journal of Chemical Kinetics, EarlyView.ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

Astrophysical symmetries [PDF]
Proceedings of the National Academy of Sciences, 1996 Astrophysical objects, ranging from meteorites to the entire universe, can be classified into about a dozen characteristic morphologies, at least as seen by a blurry eye. Some patterns exist over an enormously wide range of distance scales, apparently as a result of similar underlying physics.

Publications of the Astronomical Society of the Pacific, 1996 Ap95 differs from Ap91 to Ap94 primarily in Ap number. That is, it once again attempts to highlight some areas of our mutual science where a major event has occurred during the year (a possible solution of the Type II supernova problem, the faintness of quasar host galaxies, and the collision of Shoemaker-Levy 9 with Jupiter), but also to focus on some

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
Laser &Photonics Reviews, EarlyView.The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Leveraging Machine Learning for Photometric Redshift Estimation of JWST Galaxies
Edinburgh Student Journal of ScienceWith the launch of JWST, the volume and complexity of astronomical data are increasing, a trend that will continue with future instruments such as SKA and Euclid. It is inevitable that data-driven methods will become more prominent alongside model-driven

Metals, 2015 Planets and stars are often capable of generating their own magnetic fields. This occurs through dynamo processes occurring via turbulent convective stirring of their respective molten metal-rich cores and plasma-based convection zones.

Publications of the Astronomical Society of the Pacific, 1997 The loudest astronomical headlines of the year came from both very near (planets orbiting stars in the solar neighborhood) and very far (galaxies and parts of galaxies at redshifts of 1 to 3 and more). We explore these and other happenings in our Solar System (Galileo at Jupiter, Comet Hyakutake), Milky Way (the bursting pulsar, spotted stars), Local ...
