Monthly Notices of the Royal Astronomical SocietyWe reproduce the luminosity functions of the early-time peak optical, the late-time ultraviolet (UV)-plateau, and the peak X-ray luminosities of tidal disruption events, using an entirely first-principles theoretical approach. We do this by first fitting

Simulations of Tidal Disruption Events [PDF]
, 2020 Numerical simulations have historically played a major role in understanding the hydrodynamics of the tidal disruption process. Given the complexity of the geometry of the system, the challenges posed by the problem have indeed stimulated much work on ...

Tidal Disruption Event Demographics with the Zwicky Transient Facility: Volumetric Rates, Luminosity Function, and Implications for the Local Black Hole Mass Function [PDF]
Astrophysical Journal Letters, 2023 We conduct a systematic tidal disruption event (TDE) demographics analysis using the largest sample of optically selected TDEs. A flux-limited, spectroscopically complete sample of 33 TDEs is constructed using the Zwicky Transient Facility over 3 yr ...

Ubiquitous Late Radio Emission from Tidal Disruption Events [PDF]
Astrophysical Journal, 2023 We present radio observations of 23 optically discovered tidal disruption events (TDEs) on timescales of ∼500–3200 days postdiscovery. We detect nine new TDEs that did not have detectable radio emission at earlier times, indicating a late-time ...

Tormund's return: Hints of quasi-periodic eruption features from a recent optical tidal disruption event [PDF]
Astronomy & Astrophysics, 2023 Quasi-periodic eruptions (QPEs) are repeating thermal X-ray bursts associated with accreting massive black holes, the precise underlying physical mechanisms of which are still unclear.

A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets [PDF]
Astrophysical Journal Letters, 2023 Only a tiny fraction ∼1% of stellar tidal disruption events (TDEs) generate powerful relativistic jets evidenced by luminous hard X-ray and radio emissions.

The rebrightening of a ROSAT-selected tidal disruption event: repeated weak partial disruption flares from a quiescent galaxy? [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The ROSAT-selected tidal disruption event (TDE) candidate RX J133157.6-324319.7 (J1331), was detected in 1993 as a bright (0.2–2 keV flux of (1.0 ± 0.1) × 10−12 erg s−1 cm−2), ultra-soft (kT = 0.11 ± 0.03 keV) X-ray flare from a quiescent galaxy (z = 0.

Nitrogen enhancements 440 Myr after the Big Bang: super-solar N/O, a tidal disruption event or a dense stellar cluster in GN-z11? [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Recent observations of GN-z11 with JWST/NIRSpec revealed numerous oxygen, carbon, nitrogen, and helium emission lines at z = 10.6. Using the measured line fluxes, we derive abundance ratios of individual elements within the interstellar medium (ISM) of

Shocks Power Tidal Disruption Events [PDF]
Astrophysical Journal, 2023 Accretion of debris seems to be the natural mechanism to power the radiation emitted during a tidal disruption event (TDE), in which a supermassive black hole tears apart a star.
