Multi-Wavelength Analysis of AT 2023sva: a Luminous Orphan Afterglow With Evidence for a Structured Jet

Gokul P. Srinivasaragavan, Daniel A. Perley, Anna Y. Q. Ho +50

We present multi-wavelength analysis of ZTF23abelseb (AT 2023sva), an optically discovered fast-fading ( $Δ m_{r} = 2.2$ mag in $Δ t = 0.74$ days), luminous ( $M_{r} \sim - 30.0$ mag) and…
