I can't believe I forgot to post this?? Anyway, here's some Megans, it's been literally seven years since I posted pics of her. Jasper's been lonely _(߹𖥦߹」∠)_

 “GN-z11 flash” !

Long gamma-ray bursts (GRB), explosions of very massive stars, provide crucial information on stellar and galaxy evolution, even at redshifts z ~ 8 - 9.5, when the Universe was only 500-600 million years old.

During observations of a galaxy at a redshift of z ~ 11 (400 million years after the Big Bang), a bright signal, named GN-z11-flash, shorter than 245 s was detected and interpreted as an ultraviolet flash associated with a GRB in this galaxy, or a shock-breakout in a Population III supernova.

Its resulting luminosity would be consistent with that of other GRBs, but a discussion based on probability arguments started on whether this is instead a signal from a man-made satellite or a Solar System object.

Here we show a conclusive association of GN-z11-flash with Breeze-M upper stage of a Russian Proton rocket on a highly elliptical orbit.

This rules out GN-z11-flash as the most distant GRB ever detected. It also implies that monitoring of a larger sample of very high redshift galaxies is needed to detect such distant GRBs. This also highlights the importance of a complete database of Earth satellites and debris, which can allow proper interpretation of astronomical observations.

Fermi Telescope finds new feature in brightest gamma-ray burst yet seen

In October 2022, astronomers were stunned by what was quickly dubbed the BOAT—the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi Gamma-ray Space Telescope reveals a feature never seen before. "A few minutes after the BOAT erupted, Fermi's Gamma-ray Burst Monitor recorded an unusual energy peak that caught our attention," said lead researcher Maria Edvige Ravasio at Radboud University in Nijmegen, Netherlands, and affiliated with Brera Observatory, part of INAF (the Italian National Institute of Astrophysics) in Merate, Italy. "When I first saw that signal, it gave me goosebumps. Our analysis since then shows it to be the first high-confidence emission line ever seen in 50 years of studying GRBs." A paper about the discovery appears in the journal Science.

AT2021lwx

In our lives, we see and experience many powerful things, from Earthquakes, Hurricanes, Tornado's, a thunder storm can feel fairly powerful, as can the eyes of the person you share the first kiss with, but on a galactic scale, and not to rain on your life's parade, but the real action is in outer space.

It's a human failing that we only consider the things that directly impact on us, when we consider power, but for anybody who looks up to the sky, perspective can be a real teacher.

Until recently, the most powerful explosions were GRB's (Gamma Ray Bursts) a flash of energy far beyond any Earthly experience, thought to be created during the merger of neutron stars or the collapse of some of the largest stars, these momentary flashes can contain more energy than our Sun will emit in it's entire 10 billion years of life, and then some ! all condensed in a momentary blast.

But back in 2020 a new object was detected by the Zwicky Transient Facility in California, and the observations sat there for almost a year before finally being found by a search algorithm and named AT2021lwx.

Now Gamma Ray Bursts last seconds, Supernova can last months, but this object is still burning today, 3 years since it's discovery and it's the prolonged output of this object that has made it the most energetic, not in terms of brightness, but overall output.

But what is it ?

If it's not a gamma ray burst, and it's not a supernova, maybe it's a star tidally ripped apart by a black hole, another massively powerful event, yet again, that wouldn't have lasted this long.

The only conclusion so far, is that this is similar to a quasar, a supermassive black hole that is constantly being fed material and emitting huge amounts of energy, so much so, that it outputs more energy alone than it's entire galaxy that's powering it.

Yet, these objects flicker and don't turn on and off, while this object appeared in 2020 and doesn't flicker at all.

Still, the most likely reason is a massive body of gas being consumed by a back hole, and throwing out tremendous amounts of energy, so much so, it's become the most powerful thing ever found in our known universe.

DMO: Digimon Military Operatives_13.TXT

WE OPENED THE DOOR.

After what felt like DAYS of trying to open that goddamn door, we did it, I'll cover what's in there in this same entry, but for now, it's time to get in.

"The GRB Virus" a lot of documents covering what this virus is, is what we found inside the gates, as you probably already know, I've already covered this strange virus here, talking about how the military may want to use it to make digimon go berserk and use them for war, however, Vamdemon is way better than I am talking about this stuff, so here you have his description:

"The GRB Virus, or Gulus Realm Burst is an infection caused by the spreading of the power bared within a Digimon called Regulusmon, when the GRB factor infects a Digimon, it altera it's personality and makes them become frenzied, this however, doesn't happen to those digimon that the secretion known as "Black Digitron" the reasons for their immunity are unknown to this day"

If any of you wonder what the hell is a Black Digitron, it's a secretion created by some digimon that alters the evolution and look of some species, this species are, for example, Black Agumon or Black Galgomon.

Just as I was expecting, they want to use this GRB Factor to create an army of crazy digimon they think they could control, only god knows why, they even have a small sample of the GRB Virus in here...
