Abstract:
The Public AEON Spectroscopic Survey for Transient Astronomy (PASSTA) is a new collaboration to obtain both rapid and long-term observations of nearby supernovae discovered shortly after explosion using the 0.4 m to 8 m telescopes of the Astronomical Events Observatory Network (AEON). Our goal is to coordinate observing campaigns across research groups and observing facilities in order to minimize duplication and maximize follow-up efficiency in the LSST era. We will post all classification spectra immediately on the Transient Name Server and promptly release follow-up SOAR and GMOS spectra on WISeREP. We invite all interested research groups to apply to join the collaboration by contacting the PIs. For more information, visit astro-passta.github.io.

The Public AEON Spectroscopic Survey for Transient Astronomy (PASSTA) is a new collaboration to obtain both rapid and long-term observations of nearby supernovae discovered shortly after explosion using the 0.4 m to 8 m telescopes of the Astronomical Event Observatory Network (AEON; Street et al. 2020). The survey consists of long-term programs on Gemini (Large and Long Programs GN-LP-112 and GS-LP-213; PIs: J. E. Andrews, D. J. Sand), SOAR (NOIRLab Survey Program 2025B-886282; PI: G. Hosseinzadeh), and Las Cumbres Observatory (Key Project KEY2023B-002, “The Global Supernova Project”; PI: D. A. Howell), including both queue time and targets of opportunity. Our goal is to coordinate observing campaigns across research groups and observing facilities in order to minimize duplication and maximize follow-up efficiency in the era of Rubin Observatory’s Legacy Survey of Space and Time.

We will post all classification spectra immediately on the Transient Name Server and promptly release follow-up SOAR and GMOS spectra on WISeREP (Yaron & Gal-Yam 2012). At the time of this writing, we have released spectra of SN 2024abbv and SN 2025tis. All raw Gemini data will be made public immediately through the Gemini archive, and reduced GHOST, GNIRS, and MAROON-X data can be provided upon request.

We invite all interested research groups to apply to join the collaboration by contacting the PIs. Collaboration members will be able to participate in the selection of targets and the coordination of follow-up observations with AEON and other facilities, and will be eligible to take on formal leadership roles in the collaboration. Joining the collaboration requires an in-kind contribution of person power toward target vetting, observation planning, and/or data reduction. We also invite groups with nearby supernova programs on other facilities to apply to join and coordinate with our public observing campaigns.
