Extragalactic Spectral Line

This is the listing of the (non-HI) extragalactic spectral line science working group, addressing spectral line work not covered by the HI Science Working Group or the Our Galaxy Science Working Group.

Extragalactic Spectral Lines Working Group Introduction

The Extragalactic Spectral Lines science working group (SWG) focusses on the many astrophysically important lines besides the HI 21 cm line. With its unique sensitivity, SKA opens up the study of redshifted lines from distant galaxies or intrinsically weak lines from nearby galaxies, allowing us to trace material and various environments from the local to the distant Universe. In a pan-chromatic multi-messenger astronomy era, the SKA will complement and be operated along with other existing facilities such as ALMA, or instruments being built like the ELT, matching their angular resolution in the low frequency domain.

The science case for extragalactic spectral lines strongly advocates for an increase in coverage toward high frequencies (>15 GHz, SKA1 upgrade or SKA2).
