VizieR Online Data Catalog: IceCube's neutrinos with 4FGL, 2SXPS & CRATES data (Kun+, 2022)

In this paper we carry out a multiwavelength search of sources within the 90% containment area of 70 IceCube track-type neutrino events. In Section 2 we design an analysis to match the 70 track-type neutrino events published by IceCube and the Fermi-LAT 4FGL-DR2 catalog, the Swift-XRT 2SXPS catalog, and the CRATES Catalog.

The neutrino list compiled by Giommi+ (2020MNRAS.497..865G) summarizes 70 public IceCube high-energy cosmic neutrino tracks (recorded between 2009 October 13 and 2019 September 30) that are well reconstructed and off the Galactic plane. We use this sample to find neutrino candidate sources.

The 4FGL-DR2 catalog includes 5787 gamma sources based on ten years of survey data in the 50MeV-1TeV energy range (Ballet+ 2020arXiv200511208B), being an incremental version to the 8yr 4FGL catalog (Abdollahi+ 2020, J/ApJS/247/33). See Section 2.1.

The Swift-XRT Point Source (2SXPS) catalog covers 3790 square degrees on the sky and contains position, fluxes, spectral details, and variability information for 206,335 X-ray point sources. Observations were made with the X-ray telescope on-board the Neil Gehrels Swift Observatory between 2005 January 1 and 2018 August 1 (Evans+ 2020ApJS..247...54E, Cat. IX/58). See Section 2.2.

We searched for radio sources within the 90% containment area of neutrinos in the Combined Radio All-Sky Targeted Eight GHz Survey (CRATES, Healey+ 2007, J/ApJS/171/61). The catalog is assembled from existing observations, especially the Green Bank 6cm Radio Source Catalog (GB6, 4.8GHz), the Parkes-MIT-NRAO Survey (PMN, 4.8GHz), and the Cosmic Lens All-Sky Survey (CLASS, 8.4GHz). The existing observations were augmented by reprocessing of archival Very Large Array (VLA) and ATCA data and by new observations to fill in coverage gaps. See Section 2.3.
