We discuss the possible association of an astrophysical neutrino (IC220405B) with the recently reported, extremely energetic tidal disruption event (TDE) candidate AT2021lwx (ZTF20abrbeie, aka ``Scary Barbie'') at redshift $z=0.995$. Although the TDE is about $2.6^\circ$ off the direction of the reconstructed neutrino event (outside the 90% confidence level localization region), the TDE candidate shares some important characteristics with so far reported neutrino-TDE associations: a strong infrared dust echo, high bolometric luminosity, a neutrino time delay with respect to the peak mass accretion rate of the order of hundred days, and a high observed X-ray luminosity. We interpret this new association using an isotropic emission model, where neutrinos are produced by the collision of accelerated protons with infrared photons. After accounting for the high redshift of AT2021lwx (by interpreting the data in the SMBH frame), we find that the expected neutrino fluences and neutrino time delays are qualitatively comparable to the other TDEs. Since data are only available up to 300 days post-peak in the SMBH frame, significant uncertainties exist in the dust echo interpretation, and therefore in the predicted number of neutrinos detected, $\mathcal N_ν\simeq3.0\times10^{-3}-0.012$. We recommend further follow-up on this object for an extended period and suggest refining the reconstruction of the neutrino arrival direction in this particular case.

Spectroscopic monitoring of the candidate tidal disruption event in F01004-2237
本文介绍了超亮红外星系F01004-2237的光谱监测观测结果。这个星系被观察到其光谱发生了变化,通过比较2015年的光谱和2000年的光谱来检测。这些变化与光度增亮一致。在光谱中检测到的主要变化是增强的He II $λ$ 4686发射和He I $λ$ 3898、$λ$ 5876发射线的出现。对这些变化的有利解释是2010年发生的潮汐中断事件(TDE)。然而,随后的工作表明,这些变化是由另一个迄今未知的原因引起的,与活动星系核(AGN)吸积率的变化有关。我们的光谱监测观测表明,He线的演化与TDE中观察到的演化一致,而与AGN混响绘图研究中观察到的演化相反,重新讨论了将耀斑解释为TDE的讨论。
