TDE 2025aarm light curves

At a redshift of z=0.01368, TDE 2025aarm is the second closest TDE ever discovered, offering an unprecedented opportunity to study such phenomena in great details. We observed TDE 2025aarm in optical with the Liverpool Telescope for a total of three epochs, and complemented our dataset with ancillary spectroscopic and photometric data.

The early optical spectra are characterized by a blue-continuum and helium, hydrogen and possibly Bowen lines typical of H+He events. The optical light curves peak at M_g_~-18.68mag and are well described by fallback of a M*~0.16M_{sun}_ star onto a M_BH_~2x10^7^M_{sun}_ black hole. We report Swift-XRT detection in the 0.3-10keV range, with a total flux of F_X_~1.42x10^-14^erg/cm^2^/s, fitted by a black-body with k_BT_~0.39keV.
