As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc. Given its observed redshift of 2.219, the light travel time of TON 618 is estimated to be approximately 10.8 billion years.
PG 0844+349 has an active galactic nucleus.It is classified a Seyfert type 1.0 galaxy, [6] containing two sets of emission lines superimposed onto each other. One set of lines is a low-density (electron density n e 10 3-10 6 cm −3) ionized gas that has widths which corresponds to velocities of several hundred kilometers per second.

Ton 618 → TON 618 – No sources besides SIMBAD uses this version of the name. Peer-reviewed papers, including the paper that gave the black hole it's mass estimate, have used the capitalised version of the name. To add further, NASA uses the capitalisation as well.
QSO J0313−1806 [2] was the most distant, and hence also the oldest known quasar at z = 7.64, at the time of its discovery. [1] In January 2021, it was identified as the most redshifted (highest z) known quasar, with the oldest known supermassive black hole (SMBH) at (1.6 ± 0.4) × 10 9 solar masses.

Gadolinium isotopes have 10 metastable isomers, with the most stable being 143m Gd (t 1/2 = 110 seconds), 145m Gd (t 1/2 = 85 seconds) and 141m Gd (t 1/2 = 24.5 seconds). The primary decay mode at atomic weights lower than the most abundant stable isotope, 158 Gd, is electron capture , and the primary mode at higher atomic weights is beta decay .
Crazy Stone (Champion Go on iOS and Android platforms) is a Go playing engine, developed by Rémi Coulom, a French computer scientist. It is one of the first computer Go programs to utilize a modern variant of the Monte Carlo tree search. It is part of the Computer Go effort. In January 2012 Crazy Stone was rated as 5 dan on KGS, in March 2014 ...
