QUASARS. “Are quasars white holes? Quasars are still the most striking mystery of modern astrophysics.” https://lnkd.in/djhYFZU View in LinkedIn

HYPOTHETICAL STRUCTURE. “According to the most common hypothesis, a quasar is a distant active galaxy with a supermassive black hole in the center.” https://lnkd.in/djhYFZU View in LinkedIn

ALTERNATIVE HYPOTHESIS “is that quasar nuclei are the place of matter transition from prestellar existence in the form of super-dense bodies to existence in the form of stars and rarefied interstellar medium, which are more common for astronomy. This process may be connected with the formation of a white hole.” https://lnkd.in/djhYFZU View in LinkedIn

SHREDDED MATTER. “A tidal disruption event (TDE) occurs when a star passes close to a black hole (BH) and is torn apart by tidal forces. Debris from the star produces an accretion flare as it falls back on to an accretion disc around the BH.” https://lnkd.in/djnsGi4 View in LinkedIn

EXPLAINING SHREDDING, “Over the last decade, dozens of TDE candidates have been discovered, and the detection of various exotic transients has renewed interest in theoretical models of TDEs. Some of the most unusual candidate events could be explained as the tidal disruption of a white dwarf (WD) by a moderately massive black hole (MBH).” (TDE = tidal disruption event). https://lnkd.in/djnsGi4 View in LinkedIn

SHREDDING AND HI ENERGY BURSTS. “It has been suggested that WD-TDEs could be a source of a recently discovered population of ultra-long gamma-ray bursts.” (WD = white dwarf; TDE = tidal disruption event). https://lnkd.in/djnsGi4 View in LinkedIn

MASS DEPENDENT. “The possibility of detecting WD-TDEs is especially intriguing because the disruption of a WD is only visible if the mass of the BH, Mbh, is less than about 10(5) M⊙ or perhaps 10(6) M⊙ depending on the BH spin. For a more massive BH, the WD is ‘swallowed whole’ without disruption.” (WD = white dwarf; TDE = tidal disruption event). https://lnkd.in/djnsGi4 View in LinkedIn
