Throwback To That One Time Where Grandma Tracy Tried To Take A Nice Photo Of The Boys For Jeff…

What's a quasar? Is it a science thingy?

“A quasar, or, uh, quasi-stellar radio source as they’re more properly called, are types of Active Galactic Nuclei.” John begins to explain with a smile, “The Tracy Quasar, that is, my quasar, is one of them. AGN’s are extremely luminous and so the first signs of it were an abnormally high redshift source of electromagnetic energy on my screens, that is, uh, a load of radio waves and visible light appeared. It’s something similar to what stars emit, but my readouts were showing very broad emission lines; unlike any known from actual stars, so I knew it was something special from the moment I first pointed my telescope at it.” He laughs.

“Quasar’s are normally caused by collisions of galaxies, with the galaxies’ central black holes merging to form either a supermassive black hole or a binary black hole system.” The spaceman goes on, flicking up a diagram and shifting the data around meaningfully. “So, here, look; the Tracy Quasar is essentially a really super compact region in the centre of a massive galaxy, that surrounds one of these central supermassive black holes. See? Its size is something like ten thousand times the radius of an ordinary enclosed black hole. The energy emitted from such a quasar derives from mass that’s falling onto what we call the accretion disc around the black hole.”

“The primary star of the Tracy Quasar, that is, the largest solar body in the galaxy, is the LucilleX10-37.” John’s expression changes; softening into warm and fond as he mentions his mother’s star. “She’s got a small cluster of satellites; asteroids and exo-planets that have been named after my brothers and Father.”

“I have books written on the subject,” He adds, “though the I’m not sure whether the eponymof the S-TracyX607 has ever used my book for anything but a doorstop…”

The Reign of the Four Never Five:

Blue and gold, the brave and the bold.  Five of four, speaks the brothers of old. Broken and lost, death for recovery. Never complete, the blood of reverie.
