Dear all,
I hope you will join us for the October LINCC Tech Talk session that will take place on Thursday, October 10, at 10h PT = 13h ET = 13h CLT = 19h CET on Zoom (https://ls.st/lincc-talks ). We will hear from Emilio Donoso, who will talk about one of the recent LINCC Frameworks Incubator project on correlation functions.
Enabling Massive Correlation Functions in the LSST Era
The Large Synoptic Survey Telescope (LSST) presents an unprecedented opportunity to study galaxy clustering through its massive dataset and precise photometric redshifts. However, the scale of the data and challenges in creating suitable masks for random source generation necessitate new approaches to calculating correlation functions, a key statistical tool in cosmology and galaxy evolution. This talk will describe advancements made during the LINCC Incubator 2024 in integrating high-speed pair-counting algorithms with innovative, pixelized hierarchical catalogs (HATS/LSDB) for distributed computation of clustering estimators. We will discuss the algorithms, technologies, and code packages developed, and demonstrate their application in studying the projected cross-correlation between Gaia quasar candidates and a vast galaxy sample extracted from Subaru HSC-SSP, showcasing the potential for LSST-era cosmology research.
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.
