Claims

C1strongest claim

We interpret the observations under a model in which a rapidly-accreting central engine blows a fast (~0.2c) wind into the surrounding medium and irradiates it with X-rays. The high Doppler velocities and intense ionization within this wind prevent identifiable spectroscopic features from appearing in the ejecta or in the surrounding circumstellar material.

C2weakest assumption

That the extreme luminosity, lack of early spectral features, and later double-peaked narrow lines are produced by a rapidly accreting black hole launching a fast wind, rather than by alternative powering mechanisms or different geometries.

C3one line summary

AT2024wpp is a luminous fast UV transient powered by black hole accretion, with first pre-peak bolometric luminosity of 2x10^45 erg/s and a fast wind suppressing early spectral features until double-peaked narrow lines emerge after 35 days.
