Jansky Very Large Array at 10GHz. Several of these compact radio point sources have diffuse counterparts identified in previous multiband studies of resolved radio continuum emission. We find compact counterparts to eight star forming regions, four anomalous microwave emission candidates, and one supernova remnant (SN 2011dh). Nine of the compact radio sources match X-ray counterparts, the majority of which are background galaxies. These AGN are all within the D25 (isophotal diameter) of the host galaxy and might act as contaminants for X-ray binary population studies, highlighting the need for high-resolution multiband imaging. This study showcases the broad number of science cases that require sensitive radio facilities, like the upcoming Square Kilometre Array and the planned next generation Very Large Array.2025AJ....170..201Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/170/201CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/335 : Revised catalog of GALEX UV sources (GUVcat_AIS GR6+7) (Bianchi+ 2017)II/363 : The band-merged unWISE Catalog (Schlafly+, 2019)VIII/111 : VCCS Epoch 1 Bright Catalog Release (Peters+, 2021)IX/70 : Chandra Source Catalog Release 2 (CSC 2.1) (Evans+, 2024)J/ApJS/65/485 : 1.49GHz Atlas of Spiral Galaxies (Condon, 1987)J/ApJ/601/735 : M51 luminous X-ray sources (Terashima+, 2004)J/AJ/133/2559 : Compact radio sources in spiral galaxies.
