THE CONFERENCE


21th International Conference on Electromagnetic and Light Scattering (ELS XXI)

June 23 – 27, 2025, Milazzo, Italy

 

ELS XXI will be held in June 23-27, 2025, in Milazzo, a town in Sicily, long referred to as “the pearl of the Tyrrhenian sea”.

 

The Electromagnetic and Light Scattering (ELS) XXI meeting will focus on theoretical, computational, and experimental advances in electromagnetic and light scattering by particles with arbitrary sizes, shapes, and optical properties. 

 

Contributions will cover a broad range of topics from cosmic dust, atmospheric aerosols, remote sensing observations, particle detection and characterization, to optical trapping and nano-optics.

 

The specific topics that will be covered include (but are not limited to) the following:

  • New theoretical developments, numerical simulations, and laboratory measurements of light scattering by nonspherical and morphologically complex particles and particle groups 

  • Detection and characterization of atmospheric particulates using laboratory, in situ, and remote sensing techniques 

  • Scattering of light by terrestrial aerosols and clouds, oceanic particulates, solar system objects, exoplanets, stellar disks, and various
    astrophysical objects 

  • Applications of light scattering methods in biology and biomedicine 

  • Near-field and coherent effects in light scattering, optical trapping, and manipulation 

  • Light scattering methods to control material properties and technological applications

 

During the Conference two prestigious young-scientist awards will be presented by Elsevier together with the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT): the 2024 Richard M. Goody Award for outstanding early-career scientists in the field of atmospheric radiation, remote sensing, and climate science, and the 2024 Peter C. Waterman Award for outstanding early-career scientists who work on the theory and applications of electromagnetic scattering.

The conference is jointly organized by the Dipartimento di Scienze Matematiche e Informatiche, Scienze Fisiche e Scienze della Terra (MIFT) of the University of Messina and by the Istituto per i Processi  Chimico-Fisici (IPCF) del Consiglio Nazionale delle Ricerche (CNR).

The magnificent galaxy featured in this Hubble Picture of the Week is NGC 1559. It is a barred spiral galaxy located in the constellation Reticulum near the Large Magellanic Cloud, but much more distant at approximately 35 million light-years from Earth. Hubble last visited this object in 2018. The brilliant light captured in this image offers a wealth of information, which thanks to Hubble can be put to use by both scientists and the public. This picture is composed of a whopping ten different images taken by the Hubble Space Telescope, each filtered to collect light from a specific wavelength or range of wavelengths. It spans Hubble’s sensitivity to light, from ultraviolet around 275 nanometres through blue, green and red to near-infrared at 1600 nanometres. This allows information about many different astrophysical processes in the galaxy to be recorded: a notable example is the red 656-nanometre filter used here. Hydrogen atoms which get ionised can emit light at this particular wavelength, called H-alpha emission. New stars forming in a molecular cloud, made mostly of hydrogen gas, emit copious amounts of ultraviolet light which is absorbed by the cloud, but which ionises it and causes it to glow with this H-alpha light. Therefore, filtering to detect only this light provides a reliable means to detect areas of star formation (called H II regions), shown in this image by the bright red and pink colours of the blossoming patches filling NGC 1559’s spiral arms. These ten images come from six different observing programmes with Hubble, running from 2009 all the way up to the present year. These programmes were led by teams of astronomers from around the world with a variety of scientific goals, ranging from studying ionised gas and star formation, to following up on a supernova, to tracking variable stars as a contribution to calculating the Hubble constant. The data from all of these observations live on in the Hubble archive, available for anyone to use —
