Extended Data Fig. 2: Properties of the host of AT 2020neh.
From: A fast-rising tidal disruption event from a candidate intermediate-mass black hole
Top: The Prospector SED fit to the host galaxy photometry. All host photometry meaurements are shown with + / − 1 σ standard deviation uncertainties. Bottom left: Star formation rates vs. stellar masses for field galaxies (shown here is the SDSS spectroscopic sample as grey contours). The hosts of optical TDEs are shown in red (taken from 21). AT 2020neh sits comfortably within the parameter space occupied by other TDEs. Bottom right: A BPT diagram showing the regions where emission line ratios are indicative of ionisation from either an AGN, star formation or a composite of the two (78) The location of AT 2020neh is shown, alongside other optical TDE hosts with host SDSS spectra (21). The position of AT 2020neh inside of the star forming region of the diagram confirms the lack of an AGN component within the host.
