We would like to know whether you are interested in attending two sessions dedicated to the upcoming release of the Chandra Source Catalog version 2.1, that will take place during the AAS HEAD 20 meeting in Waikoloa Village, Hawai'i. The two sessions are:
Thursday, March 30th, 12:30 P.M.
The Chandra Source Catalog version 2.1 (CSC 2.1) adds observations released publicly between January 1, 2015 and the end of 2021, uncovers a significant portion of new sky for X-ray exploration, and has a number of algorithmic enhancements with respect to the previous version. In this splinter session we will host a hands-on workshop/tutorial for users to get familiar with the different access interfaces to CSC 2.1, including our Table Access Protocol (TAP) service that can be used with Virtual Observatory tools such as astroquery and pyvo. We also introduce users to a few science threads that exploit the catalog data products, such as light curves and spectra, and provide Jupyter notebooks that demonstrate how to access these data products and how to used them for scientific applications such as AGN selection and transient identification. This session is complementary to our accepted Special Session on the science enabled by the CSC.
Thursday, March 30th, 2:00 P.M.
The new version of the Chandra Source Catalog (CSC 2.1) is a rolling release currently in production, with processed datasets already available to the users. The final release, expected in the first half of 2023, expands on version 2.0 by adding over 4,500 observations released publicly between January 1, 2015 and December 31, 2021, corresponding to an increase of more than 40% of the sky area covered, relative to CSC2.0. The nearly 450,000 individual X-ray sources in CSC 2.1, the vast majority of which are serendipitous, represent a significant opportunity for population studies and data-driven discovery in high energy astrophysics, and a rich data repository with many applications in the era of Big Data and Open Science. In this special session we will present CSC 2.1 and highlight some relevant, cutting-edge science questions that the catalog has been used to address, through presentations on specific science projects. We will introduce attendees to the diverse dataset of tabulated properties and data products that make up the catalog, including spectra and light curves, and discuss features of CSC 2.1 that facilitate multi-wavelength science, such as our effort to align the catalog astrometry to the Gaia reference frame and the cross-matching of the CSC with Sloan Digital Sky Survey (SDSS). A diverse cohort of early career scientists will present their CSC-enabled research and discuss how CSC can be used to advance high energy astrophysics.
Please let us know if you are potentially interested in attending any of these sessions, so that we can better plan the details and keep you informed. Expressing your interest does not bind you to attend. If you wish, you can leave us your email, so that we can provide updates and resources for the session.Additional info: https://cxc.cfa.harvard.edu/csc/about2.1.html
