AT2025agpz in Rubin commissioning data: distinguishing a luminous interacting supernova from nuclear transients in compact galaxies

C. R. Angus, M. Quilt, H. F. Stevance +37

The Vera C. Rubin Observatory's Legacy Survey of Space and Time will discover unprecedented numbers of rare, long-lived optical transients, many of which will be too faint or too n…

Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl

Yize Dong, V. Ashley Villar, Anya Nugent +35

In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…

Characterizing Supernova Host Galaxies with FrankenBlast: A Scalable Tool for Transient Host Galaxy Association, Photometry, and Stellar Population Modeling

Anya E. Nugent, V. Ashley Villar, Alex Gagliano +5

We present FrankenBlast, a customized and improved version of the Blast web application. FrankenBlast associates transients to their host galaxies, performs host photometry, and ru…

Hierarchical Cross-entropy Loss for Classification of Astrophysical Transients

V. Ashley Villar, Kaylee de Soto, Alex Gagliano

Astrophysical transient phenomena are traditionally classified spectroscopically in a hierarchical taxonomy; however, this graph structure is currently not utilized in neural net-b…
