Extended Data Fig. 1: Light curve of AT 2020neh.
From: A fast-rising tidal disruption event from a candidate intermediate-mass black hole
The UV-optical light curve of AT 2020neh throughout its observable lifetime. Grey dashed lines mark spectroscopic epochs, the dashed black line marks the peak of optical emission. Limits represent 3 σ upper limits to the flux for each telescope during periods of non-detection. There is an apparent gap in optical data between 40-60 days due to poor weather. AT 2020neh is first detected within YSE (PS1) imaging in the i-band, confirmed by with a g-band detection from ZTF <24 hours later. Pre-explosion monitoring allows for strong constraints to be placed upon the explosion epoch of the transient.
