The rise and fall of the iron-strong nuclear transient PS16dtm

T. Petrushevska et al.

Summary: The study of PS16dtm, a nuclear transient in a Narrow Line Seyfert 1 (NLSy1) galaxy, reveals that its observed properties are difficult to reconcile with normal AGN variability. Despite differences compared to TDEs in quiescent galaxies, PS16dtm displays broad Balmer line profiles and Fe II complexes, suggesting that it may still be a tidal disruption event. This implies that some changing look episodes in AGN may be triggered by TDEs.

A detailed spectroscopic study of tidal disruption events

P. Charalampopoulos et al.

Summary: This article presents the first detailed spectroscopic population study of 16 optical and UV tidal disruption events (TDEs). The study investigates the evolution of emission lines, such as Hydrogen, Helium, and Bowen lines, in terms of line luminosities, velocity widths, and velocity offsets. It also explores correlations between line luminosities and radii (R-BB) as well as temperatures (T-BB). The findings suggest a linear relationship between H alpha luminosity and R-BB and a potential inverse power-law relation with T-BB.

AT 2019avd: A Tidal Disruption Event with a Two-phase Evolution

Jin-Hong Chen et al.

Summary: Tidal disruption events (TDEs) provide a promising method to study and uncover the nature of quiescent supermassive black holes (SMBHs) at the centers of galaxies through the disruption of stars. The recent TDE candidate AT 2019avd exhibits double peaks in its optical light curve, indicating a two-phase scenario involving stream circularization and delayed accretion. The fitting analysis suggests that AT 2019avd could be interpreted as the partial disruption of a 0.9 solar mass star by a 7 x 10(6) solar mass SMBH, but the result is sensitive to the stellar model. Additionally, the large-amplitude X-ray variability in AT 2019avd can be explained by the precession of a misaligned accretion disk caused by the spinning SMBH, with a precession period of 10-25 days.

Discovery of ATLAS17jrp as an Optical-, X-Ray-, and Infrared-bright Tidal Disruption Event in a Star-forming Galaxy

Yibo Wang et al.

Summary: ATLAS17jrp is an extraordinary tidal disruption event discovered in the star-forming galaxy SDSS J162034.99+240726.5. Its light curves in the optical/UV rise to a peak luminosity and then decay with a roughly constant temperature. The optical spectra show a blue continuum and very broad Balmer lines, which gradually narrowed over time. Additionally, a delayed and rapidly rising X-ray flare was detected after the optical peak.

An elliptical accretion disk following the tidal disruption event AT 2020zso

T. Wevers et al.

Summary: This study examines the spectroscopic observations of the transient event AT 2020zso hosted by an active galactic nucleus, aiming to characterize the properties of its newly formed accretion flow. The results show a highly elliptical geometry for the new accretion flow, with implications for the high inclination nature and eccentricity of the system. Additionally, constraints on the black hole spin and disk viscosity were obtained through optical spectroscopy analysis.

Energetic nuclear transients in luminous and ultraluminous infrared galaxies

T. M. Reynolds et al.

Summary: Energetic nuclear outbursts have been found in luminous and ultraluminous infrared galaxies (U/LIRGs) at a higher rate than expected. Through a search in mid-IR data from the WISE satellite, three new transients in addition to two previously known cases were discovered in a sample of 215 U/LIRGs. These transients are all part of major galaxy mergers and have a significant contribution from an active galactic nucleus (AGN). The transients have luminosities and energetics ranging from 10(50.9) erg to 10(52.2) erg, and their infrared emissions are consistent with re-radiation from an accretion event onto a supermassive black hole. The rate of these events is significantly higher than that of large amplitude flares shown by AGN in the optical, indicating the presence of a dust-obscured population of tidal disruption events (TDEs) in U/LIRGs undergoing major galaxy mergers. Further searches and multi-wavelength follow-up are needed to determine the rate and nature of these transients.

The nuclear transient AT 2017gge: a tidal disruption event in a dusty and gas-rich environment and the awakening of a dormant SMBH

F. Onori et al.

Summary: We present the results of a dense multwavelength follow-up campaign on the nuclear transient AT 2017gge, finding consistent evidence for a tidal disruption event (TDE) nature. We observe a soft X-ray flare followed by extreme coronal line emission (ECLEs), as well as an infrared echo and the detection of a transient high-ionization coronal NIR line. These findings suggest that the TDE occurs in a gas-and-dust rich environment and the emissions in different wavelengths have different origins and locations.

Tidal Disruption Events

Suvi Gezari

Summary: The concept of stars being torn apart and consumed by massive black holes in galaxies fascinated theorists in the late 1970s. Observational evidence for these rare events emerged in the 1990s with the soft X-ray ROSAT All-Sky Survey and has accelerated with advancements in optical time domain surveys. Multiwavelength observations of TDEs have revealed panchromatic emission from different spatial scales, providing important clues to the powering mechanisms of the components.

Infrared Echoes of Optical Tidal Disruption Events: ∼1% Dust-covering Factor or Less at Subparsec Scale

Ning Jiang et al.

Summary: A statistical study was conducted on the infrared variability of 23 optical tidal disruption events (TDEs) discovered between 2009 and 2018, revealing that 11 objects showed significant variability in at least one band, with peak dust luminosity around 10^41-10^42 erg s^-1. The derived dust-covering factor (f(c)) of these TDEs is generally much lower compared to dusty tori in active galactic nuclei, indicating a possible scarcity of dust or a geometrically thin and flat disk near supermassive black holes.

Accretion disc cooling and narrow absorption lines in the tidal disruption event AT2019dsg

G. Cannizzaro et al.

Summary: The study presents the results of a multiwavelength follow-up campaign of the TDE AT2019dsg, showing that the host galaxy exhibits no evidence of an active galactic nucleus, but instead narrow optical emission lines likely from star formation activity. The transient is luminous in various wavelengths such as X-rays, radio, UV, and optical, with the X-ray emission becoming undetected after around 100 days. The observations are consistent with the detection of the inner regions of a cooling accretion disc.

Reverberation in Tidal Disruption Events: Dust Echoes, Coronal Emission Lines, Multi-wavelength Cross-correlations, and QPOs

Sjoert van Velzen et al.

Summary: Stellar tidal disruption events are typically discovered through transient emissions, but they can be reprocessed by gas or dust resulting in multiple reverberation signals. These signals have been detected and provide insights into important properties of TDEs. Anticipation is high for the detection of more reverberation signals with the next generation of X-ray and infrared instruments.

Seventeen Tidal Disruption Events from the First Half of ZTF Survey Observations: Entering a New Era of Population Studies

Sjoert van Velzen et al.

Summary: Tidal disruption events (TDEs) have been studied as laboratories for quiescent black holes, but the small number of known TDEs and uncertainties in their emission mechanism have hindered progress. Analysis of optical/UV light curves of 17 new TDEs reveals distinct properties based on spectroscopic class. TDEs with Bowen fluorescence features have smaller blackbody radii and lower optical luminosities, while those with only helium emission lines have the longest rise times and highest luminosities.
