WebWhile tidal disruption events (TDEs) have long been heralded as laboratories for the study of quiescent black holes, the small number of known TDEs and uncertainties in their emission mechanism have hindered progress toward this promise. Here we present 17 new TDEs that have been detected recently by the Zwicky Transient Facility along with Swift UV and X … Web8 feb 2024 · There has been a recent expansion of spectroscopic subclasses for TDEs, from the first optical TDE spectra (van Velzen et al. 2011; Gezari et al. 2012), one of which surprisingly showed only broad He ii lines and no hydrogen emission (Gezari et al. 2012), to the He-rich to H-rich sequence proposed by Arcavi et al. , to including classes with … WebGezari, Suvi Abstract The concept of stars being tidally ripped apart and consumed by a massive black hole (MBH) lurking in the center of a galaxy first captivated theorists in the … scout father tf2

Web14 set 2024 · Dr. Suvi Gezari, head of the Johns Hopkins team, explains that only some of a star's mass gets sucked into a black hole when the two bodies collide. "When the star is ripped apart by the gravitational forces of the black hole, some part of the star's remains falls into the black hole, while the rest is ejected at high speeds," she stated.

Web28 gen 2024 · Gezari and her colleagues found that the TDE spectra fell into three classes, dominated by hydrogen, helium, or a mixture of gases. Hydrogen likely signals large, young stars, whereas helium events could point to the cores of older stars whose hydrogen shells were stripped away—perhaps by an earlier brush with the black hole.
