  • 1RST ANNOUNCEMENT - 25 OCTOBER 2020

    Dear colleagues.

    We are pleased to announce the Third Workshop:

    CHEMICAL ABUNDANCES IN GASEOUS NEBULAE: OPEN PROBLEMS IN NEBULAR ASTROPHYSICS

    This workshop will take place during the week 24 - 28 May 2021 and will be held virtually using the ZOOM platform.

    The purpose of this workshop is to bring together scientists and students to share our knowledge and collaboratively discuss crucial issues related to the chemical abundances in gaseous nebulae, including implications from recent surveys. The workshop will cover all major theoretical and observational aspects of the study of chemical abundance in HII regions and Planetary Nebulae as well as in Active Galactic Nuclei. For five days, extensive discussions about specific issues in these areas covered by the workshop will be provided. Also, implications of several recent surveys to chemical abundance studies will be discussed.


    In particular, the topics to be addressed are:

    - Abundance discrepancy in HII regions and Planetary Nebulae

    - Methods to determine the chemical abundance in gaseous nebulae

    - Ionization correction factors of HII regions and Planetary Nebulae

    - Determination of chemical abundances in AGN and high redshift galaxies

    - Implications of chemical abundances in gaseous nebulae in understanding galaxy evolution

    - Ultraviolet, optical and infrared spectroscopy of gaseous nebulae

    - Abundance determinations in AGNs at low and high-z

    - Determination of the atomic parameters

    - Implications of new generation telescopes on chemical abundance determinations in gaseous nebulae

    - Recent surveys and projects on chemical abundances in gaseous nebulae and AGNs
