AI Thread Summary
MC22 is a bright astronomical source emitting at L=10^31W, but lacks rapid periodic pulsations in its X-ray flux, complicating its classification. The emission is likely due to material accretion from a star, suggesting it could be either a neutron star or a black hole. The discussion seeks to determine if one or both possibilities can be conclusively excluded based on the available data. Additionally, questions arise about the object's mass, reality, and dimensions. Clarifying these aspects is crucial for understanding the nature of MC22.

Can anyone help please,

MC22 is a very bright source, radiating at L=10^31W. However, no rapid periodic pulsations are apparent in the X-ray flux. It suggested that this emission arises from accretion of material from a star onto either a neutron star or black hole. From these facts can you conclusively exclude neither, one or both of these possibilities? Show how you arrived at your answer.

Any help would be great,

thank you Col.

How do you work out the mass of the object please?
 
Is MC22 real or imaginary object?
How far is it? (Length)

What is it's width?
*10^31?

This may help you if you currently do not know L or W of MC22 whether real or imagined.

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...
