Unravelling the Mystery of "Faint Regime" in Cosmological Explosions

AI Thread Summary
The term "faint regime" in cosmological explosions likely refers to astronomical objects that are either distant and exhibit low brightness (low flux) or are intrinsically low in luminosity. This concept is relevant in the context of phenomena like X-ray flashes, where detection is challenging due to their faintness. Understanding this regime is crucial for interpreting observations and the underlying physics of these events. The discussion highlights the need for further clarification and references to relevant research papers for deeper insights. Overall, the faint regime plays a significant role in the study of cosmological explosions.

What do they mean with "faint regime", when they talk about cosmological explosions?? (e.g X-ray flashes)

thnx

I have no idea, can you give us a link to the paper you are reading? I'm guessing they're speaking of objects that are far away and therefore aren't very bright (i.e. low flux). Though it's also possible they're referring to some technical class of objects that are intrinsically faint (i.e. low luminosity).
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
