Hostless candidates detected by ELEPHANT
Source Group: COIN
Abstract:
We report 4 hostless candidates selected by the ELEPHANT pipeline.
Transient astronomical events that exhibit no evident association with a host galaxy are rare phenomena associated with energetic events. They can offer unique insights into the properties and evolution of stars and galaxies. In this context, we developed the ELEPHANT pipeline (Pessi et al. 2024) to process alerts from the Zwicky Transient Facility (ZTF; Bellm et al. 2019; Graham et al. 2019) ingested by the Fink broker (Möller et al. 2021) and automatically find hostless candidates.
This report includes recent hostless candidates, sumarized below. We encourage classification and follow up of these targets.
