We discuss the nature of a discrete, compact radio source (NGC 4725 B) located $\approx$1.9 kpc from the nucleus in the nearby star-forming galaxy NGC 4725, which we believe to be a new detection of extragalactic Anomalous Microwave Emission (AME). Based on detections at 3, 15, 22, 33, and 44 GHz, NGC 4725 B is a $\mu$Jy radio source peaking at $\approx$33 GHz. While the source is not identified in $BVRI$ photometry, we detect counterparts in the mid-infrared $Spitzer$/IRAC bands (3.6, 4.5, 5.8…

Detecting outliers in astronomical images with deep generative networks
• Computer Science, Physics
Monthly Notices of the Royal Astronomical Society
• 2020
This work explores the ability of deep generative networks for detecting outliers in astronomical imaging data sets by using a generative model to learn a representation of expected data defined by the training set and then looking for deviations from the learned representation by looking for the best reconstruction of a given object.
