13th Serbian Conference on Spectral Line Shapes in Astrophysics
Belgrade, Serbia, August 23 - 27, 2021

Scientific Rationale

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.

The program will focus on:

This is the 13th conference in the series. The official website of the conference is http://servo.aob.rs/scslsa/ or http://www.scslsa.matf.bg.ac.rs. All materials (programme, talks, presentations, photos, etc.) from the previous meetings are available at http://servo.aob.rs/eeditions/SCSLSA.php through Serbian Virtual Observatory (http://servo.aob.rs).

Special Issue: Spectral Line Shapes in Astrophysics


During these uncertain and unprecedented times caused by the novel corona virus, it is hard to plan attendance of conferences. However, we hope that the situation will be significantly better in August 2021. In any case, we intend to organize a blended conference, with on-line and in-person presentations. On-line format of attendance is assumed for those who can not participate in-person. The Organizing committee will monitor the situation with the COVID19 pandemic and in the case of serious situation, the format of the conference will be switched to fully on-line.

Please regularly check the COVID19 - Entry Conditions


During the 13th SCSLSA, we will have a Special session, Spectroscopy and polarization of AGNs: From observations to the theory, organized in memory of the life and work of Prof. Victor Leonidovich Afanasiev.

To investigate the innermost part of Active Galactic Nuclei (AGNs), high quality spectral and polarimetric data are needed. The observations of emitting gas close to the supermassive black hole (SMBH), assumed to be the AGN central engine, are especially important. The spectral line shapes and polarization across these lines provide us with the kinematics of emitting gas. For these reasons, the complex spectral and polarimetric observations, in combination with theory, can give more information about the physical processes near the SMBH. Moreover, these studies can be used for measurements of the SMBH mass. In this Session, we are going to collect a number of lectures concerning AGN investigations using observations in spectral and polarimetric modes as well as the theoretical approach which can explain the obtained observational results.

This Session is devoted to Prof. Victor L. Afanasiev, who sadly passed away on December 21, 2020. Prof. Afanasiev was a pioneer in developing instrumentation and techniques for optical observations of AGNs. He made a significant contribution to the polarimetric and 3D spectroscopic observations of AGNs, improved the observational techniques and created new ones which are used for the deeper and more detailed investigations of AGNs.
