This article examines the spectroscopic properties of young stellar objects, linking accretion dynamics to observed ...

Optical antennas transform light from freely propagating waves into highly localized excitations that interact strongly with matter. Unlike their radio frequency counterparts, optical antennas are ...

Plasmon-enhanced molecular spectroscopies have attracted tremendous attention as powerful detection tools with ultrahigh sensitivity down to the single-molecule level. The optical response of ...

Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

The microseepage of gaseous hydrocarbons often creates a soil atmosphere containing lighter hydrocarbons (C1-C5). The gases in the soil may be sampled and analyzed to determine the specific mix of ...

An international team of astronomers led by professor Neeraj Gupta, astronomer at the Inter University Centre for Astronomy and Astrophysics (IUCAA), India, on Wednesday released the most ...

Fraunhofer lines, discovered in 1814, are dark lines in the Sun's spectrum caused by the absorption of specific wavelengths of light by elements in the solar atmosphere, marking the birth of ...
