Description
15 compact groups of galaxies observed with Chandra, Swift, and Spitzer instruments, providing data for 47 galaxies. The catalog presents total X-ray luminosities from off-nuclear point sources, along with derived star formation rates, stellar masses, and specific star formation rates. This table was created by NASA's HEASARC in May 2019 based on published astrophysical research.
Use Cases
Correlating X-ray luminosity with star formation rate based on the Mineo et al. correlation mentioned in the description
Studying the effects of low metallicity and high interaction levels on X-ray luminosity excesses described in the data
Modeling X-ray binary luminosity functions to assess stochastic variability effects noted in the study
Comparing elliptical and S0 galaxy X-ray emissions against the Boroson et al. stellar mass correlation referenced in the catalog
Strengths
Data is derived from multiple space-based observatories: Chandra/ACIS, Swift/UVOT, and Spitzer/IRAC-MIPS
Focuses on a specific sample of 47 galaxies within 15 compact groups
Includes derived astrophysical parameters like SFRs, stellar masses, sSFRs, and X-ray luminosities
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count is unknown, which may limit suitability assessment
Description metadata is limited; actual data quality requires manual inspection after download
