Dear all,
I hope you will join us for the May LINCC Tech Talk session that will take place on Thursday, May 8, at 10h PT = 13h ET = 13h CLT = 19h CET on Zoom (https://ls.st/lincc-talks ). We will hear from Amanda Wasserman, who will talk about one of the recent LINCC Frameworks incubator programs, RESSPECT, a recommendation system for spectroscopic followups.
Modular Metrics for the LSST Spectroscopic Recommendation System by Amanda Wasserman
The Legacy Survey of Space and Time (LSST) will observe over 10^6 transients per year, increasing the number of yearly discovered transients by a factor of 100. Spectroscopy is essential for probing supernova progenitor physics and accurately estimating cosmological parameters, along with gaining information on many other open questions in astronomy. However, spectroscopic resources are scarce, an expected <1% will be followed up. Due to the incoming immense quantity of transient sources, we need an automated system to sort through the millions of Rubin supernovae and prioritize the most scientifically interesting for follow-up. I present the LSST Spectroscopic Recommendation System to select the most useful supernovae based on a user specified metric. Anomaly Detection and Type Ia Cosmology are two of the metrics currently integrated into the RESSPECT pipeline, and I will illustrate how a user can add their own custom metrics to find the objects they care most about. Recommendations from the pipeline can be submitted to the DESC Target and Observation Manager which will enable coordination with various spectroscopic telescopes.
LINCC Tech Talks are held on the second Thursday of every month. Events are also advertised at our web page and also provided in calendar form ; and the #lincc-tech-talks LSSTC Slack channel is always available for discussions before, during, and after the talks.
