Optical evolution of AT 2024wpp: the high-velocity outflows in Cow-like transients are consistent with high spherical symmetry

M. Pursiainen, T. L. Killestein, H. Kuncarayakti +17

We present the analysis of optical data of a bright and extremely-rapidly evolving transient, AT2024wpp, whose properties are similar to the enigmatic AT2018cow (aka the Cow). AT20…

SN 2023tsz: A helium-interaction driven supernova in a very low-mass galaxy

B. Warwick, J. Lyman, M. Pursiainen +49

SN 2023tsz is a Type Ibn supernova (SNe Ibn) discovered in an extremely low-mass host. SNe Ibn are an uncommon subtype of stripped-envelope core-collapse SNe. They are characterise…

CSS161010: a luminous, fast blue optical transient with broad blueshifted hydrogen lines

Claudia P. Gutiérrez, Seppo Mattila, Peter Lundqvist +38

We present ultraviolet, optical and near-infrared photometric and optical spectroscopic observations of the luminous, fast blue optical transient (LFBOT), CSS161010:045834-081803 (…

Constraints on Relativistic Jets from the Fast X-ray Transient 210423 using Prompt Radio Follow-Up Observations

Dina Ibrahimzade, R. Margutti, J. S. Bright +16

Fast X-ray Transients (FXTs) are a new observational class of phenomena with no clear physical origin. This is at least partially a consequence of limited multi-wavelength follow u…
