The flare of radiation from the tidal disruption and accretion of a star can be used as a marker for supermassive black holes that otherwise lie dormant and undetected in the centres of distant galaxies. Previous candidate flares have had declining light curves in good agreement with expectations, but with poor constraints on the time of disruption and the type of star disrupted, because the rising emission was not observed. Recently, two ‘relativistic’ candidate tidal disruption events were… 

DISCOVERY OF TRANSIENT INFRARED EMISSION FROM DUST HEATED BY STELLAR TIDAL DISRUPTION FLARES

Stars that pass within the Roche radius of a supermassive black hole will be tidally disrupted, yielding a sudden injection of gas close to the black hole horizon which produces an electromagnetic

A likely decade-long sustained tidal disruption event

Multiwavelength flares from tidal disruption and accretion of stars can be used to find and study otherwise dormant massive black holes in galactic nuclei1. Previous well-monitored candidate flares

A luminous X-ray outburst from an intermediate-mass black hole in an off-centre star cluster

A unique signature for the presence of massive black holes in very dense stellar regions is occasional giant-amplitude outbursts of multi-wavelength radiation from tidal disruption and subsequent

PREDICTIONS FOR THE REVERBERATING SPECTRAL LINE FROM A NEWLY FORMED BLACK HOLE ACCRETION DISK: CASE OF TIDAL DISRUPTION FLARES

Tidal disruption events (TDEs) can be perfect probes of dormant supermassive black holes in normal galaxies. During the rising phase, the accretion luminosity can increase by orders of magnitude in

Flows of X-ray gas reveal the disruption of a star by a massive black hole

TLDR
Flows of hot, ionized gas are detected in high-resolution X-ray spectra of a nearby tidal disruption event, ASASSN-14li in the galaxy PGC 043234, consistent with a rotating wind from the inner, super-Eddington region of a nascent accretion disk, or with a filament of disrupted stellar gas near to the apocentre of an elliptical orbit.

A tidal disruption event in the nearby ultra-luminous infrared galaxy F01004-2237

Tidal disruption events (TDEs), in which stars are gravitationally disrupted as they pass close to the supermassive black holes in the centres of galaxies1, are potentially important probes of strong

THE X-RAY THROUGH OPTICAL FLUXES AND LINE STRENGTHS OF TIDAL DISRUPTION EVENTS

We study the emission from tidal disruption events (TDEs) produced as radiation from black hole accretion propagates through an extended, optically thick envelope formed from stellar debris. We

Tidal disruption and magnetic flux capture: powering a jet from a quiescent black hole

The transient Swift J1644+57 is believed to have been produced by an unlucky star wandering too close to a supermassive black hole (BH) leading to a tidal disruption event. This unusual flare

Ultraviolet and optical observations of tidal disruption events

Tidal disruption events are expected to produce a luminous flare of radiation from fallback accretion of tidally disrupted stellar debris onto the central supermassive black hole. The first

A bright year for tidal disruptions

When a star is tidally disrupted by a supermassive black hole (BH), roughly half of its mass falls back to the BH at super-Eddington rates. Being tenuously gravitationally bound and unable to cool

Optical Flares from the Tidal Disruption of Stars by Massive Black Holes

A star that wanders too close to a massive black hole (BH) is shredded by the BH's tidal gravity. Stellar gas falls back to the BH, releasing a flare of energy. In anticipation of upcoming transient

Multiband light curves of tidal disruption events

Unambiguous detection of the tidal disruption of a star would allow an assessment of the presence and masses of supermassive black holes in quiescent galaxies. It would also provide invaluable

LUMINOUS THERMAL FLARES FROM QUIESCENT SUPERMASSIVE BLACK HOLES

A dormant supermassive black hole lurking in the center of a galaxy will be revealed when a star passes close enough to be torn apart by tidal forces, and a flare of electromagnetic radiation is

Relativistic jet activity from the tidal disruption of a star by a massive black hole

TLDR
Observations of a bright X-ray flare from the extragalactic transient Swift J164449.3+573451 conclude that they have captured the onset of relativistic jet activity from a supermassive black hole.

A Huge Drop in the X-Ray Luminosity of the Nonactive Galaxy RX J1242.6–1119A, and the First Postflare Spectrum: Testing the Tidal Disruption Scenario

In recent years, indirect evidence has emerged suggesting that many nearby nonactive galaxies harbor quiescent supermassive black holes. Knowledge of the frequency of occurrence of black holes, of

Flares from the Tidal Disruption of Stars by Massive Black Holes

Tidal disruption flares are differentiated into two classes: those that are sub-Eddington and those that radiate near the Eddington limit. Flares from black holes above ~2×107 M☉ will generally not

Evolution of tidal disruption candidates discovered by XMM-Newton

TLDR
It is shown that the detected low-state X-ray emission for these two candidates has properties such that it must still be related to the flare, and the tidal disruption rate as derived from the XMM-Newton slew survey has been computed and agrees with previous studies.

A Possible Relativistic Jetted Outburst from a Massive Black Hole Fed by a Tidally Disrupted Star

TLDR
Observations suggest a sudden accretion event onto a central MBH of mass about 106 to 107 solar masses, which leads to a natural analogy of Sw 1644+57 to a temporary smaller-scale blazar.

Birth of a relativistic outflow in the unusual γ-ray transient Swift J164449.3+573451

TLDR
It is concluded that the tidal disruption of a star naturally explains the observed high-energy properties and radio luminosity and the inferred rate of such events, and the weaker beaming in the radio-frequency spectrum relative to γ-rays or X-rays suggests that radio searches may uncover similar events out to redshifts of z ≈ 6.

Optical Appearance of the Debris of a Star Disrupted by a Massive Black Hole

We show that the disruption of a star by a ~106 M☉ black hole in a galactic nucleus could under favorable circumstances produce an optically thick envelope that radiates with a thermal spectrum at
