A recent bright emission observed by the Swift satellite is due to the sudden accretion of a star onto a massive black hole. Gas accretion onto some massive black holes (MBHs) at the centers of galaxies actively powers luminous emission, but most MBHs are considered dormant. Occasionally, a star passing too near an MBH is torn apart by gravitational forces, leading to a bright tidal disruption flare (TDF). Although the high-energy transient Sw 1644+57 initially displayed none of the… Expand
Relativistic jet activity from the tidal disruption of a star by a massive black hole
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. Expand
A radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li
Radio follow-up observations of known thermal stellar tidal disruption flares (TDFs) are monitored and a detection of variable radio emission from a thermal TDF, which is interpreted as originating from a newly launched jet, suggests that all TDFs could be accompanied by a jet. Expand
Discovery of the Onset of Rapid Accretion by a Dormant Massive Black Hole
Massive black holes are believed to reside at the centres of most galaxies. They can be- come detectable by accretion of matter, either continuously from a large gas reservoir or impulsively from theExpand
Prompt emission from tidal disruptions of white dwarfs by intermediate mass black holes
We present a qualitative picture of prompt emission from tidal disruptions of white dwarfs (WD) by intermediate mass black holes (IMBH). The smaller size of an IMBH compared to a supermassive blackExpand
The tidal disruption of a star by a supermassive black hole provides us with unique information for otherwise dormant galactic nuclei. It has long been predicted that the disruption will beExpand
Birth of a relativistic outflow in the unusual γ-ray transient Swift J164449.3+573451
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.

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 flareExpand

Abstract We present the discovery and monitoring observations of Swift 1644+57, a luminous outburst from the nucleus of a galaxy at z = 0.35. Precise astrometry ties the source to within a fewExpand
Tidal disruption of main-sequence stars by black holes has generally been thought to lead to a signal dominated by UV emission. If, however, the black hole spins rapidly and the poloidal magneticExpand
GRB060218 as a Tidal Disruption of a White Dwarf by an Intermediate-mass Black Hole
A highly unusual pair of a gamma-ray burst (GRB) GRB060218 and an associated supernova SN2006aj has puzzled theorists for years. A supernova shock breakout and a jet from a newborn stellar massExpand


Radio transients from stellar tidal disruption by massive black holes
The tidal disruption of a star by a supermassive black hole provides us with a rare glimpse of these otherwise dormant beasts. It has long been predicted that the disruption will be accompanied by aExpand
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 at a rate initially exceeding the Eddington rate, releasing a flareExpand
Spectroscopic Signatures of the Tidal Disruption of Stars by Massive Black Holes
During the tidal disruption of a main sequence star by a massive black hole (BH) having mass MBH � 10 7 M� , the stellar debris falls back to the BH at a rate well above the Eddington rate. SomeExpand
An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
Multiwavelength observations of a unique γ-ray–selected transient detected by the Swift satellite, accompanied by bright emission across the electromagnetic spectrum, and whose properties are unlike any previously observed source are presented. Expand
The tidal disruption of a star by a massive black hole
Results are reported from a three-dimensional numerical calculation of the tidal disruption of a low-mass main-sequence star on a parabolic orbit around a massive black hole (Mh = 10 to the 6thExpand
Constraining the Rate of Relativistic Jets from Tidal Disruptions Using Radio Surveys
Tidal disruptions of stars by massive black holes produce transient accretion flows that flare at optical, UV, and X-ray wavelengths. At late times, these accretion flows may launch relativistic jetsExpand
The Jet-Disk Connection and Blazar Unification
We discuss the relation between the power carried by relativistic jets and the nuclear power provided by accretion for a group of blazars, including flat-spectrum radio quasars (FSRQs) and BL LacExpand
The Star Ingesting Luminosity of Intermediate-Mass Black Holes in Globular Clusters
The dynamics of stars in the inner regions of nearby globular clusters (GCs) such as G1 indicate the presence of central concentrated dark masses, and one would like to know whether these are indeedExpand
Fast TeV variability in blazars: jets in a jet
The fast TeV variability of the blazars Mrk 501 and PKS 2155−304 implies a compact emitting region that moves with a bulk Lorentz factor of Γem∼ 100 towards the observer. The Lorentz factor isExpand
Tidal disruption of stars by black holes of 106–108 solar masses in nearby galaxies
Stars in galactic nuclei can be captured or tidally disrupted by a central black hole. Some debris would be ejected at high speed', the remainder would be swallowed by the hole, causing a brightExpand
