The spectral lines, their widths, and, more generally, the shapes, are powerful tools for emitting/absorbing gas diagnostics in different astrophysical objects, (from the Solar system to the most distant objects in the Universe - quasars. The emission/absorption lines of astrophysical objects are produced over a wide range of distances from an observer and under a wide range of physical and kinematic conditions. Therefore, in astrophysical objects the lines from X-ray (e.g. Fe Ka) to the radio (e.g., the radio recombination lines) wavelength range have been observed. On the other hand, the experimental and theoretical investigations of laboratory plasma have been used in spectroscopic astrophysical research; in particular, the same atomic data are needed for line-shape calculations. This conference will bring together astronomers (observers and theoreticians) and physicists from Serbia and elsewhere to review the present stage of research, with the aim of improving our knowledge in this field, and to better understand the significance of emission/absorption lines for future astrophysical investigations.
