AI Thread Summary
The lab project focuses on using a radio telescope to map 21cm neutral Hydrogen in the galaxy, aiming to create a comprehensive image. The researcher seeks to explore specific properties of the hydrogen that could provide insights into the galaxy's structure and dynamics. Suggestions include studying the power spectrum of brightness temperature, which can reveal information about the intergalactic medium, and investigating galactic warp to understand galactic dynamics. The project emphasizes not just mapping but also deriving meaningful conclusions from the data collected. Engaging with these aspects could enhance the overall findings of the experiment.

This semester I'll be doing a lab project using a radio telescope to map out 21cm neutral Hydrogen in the galaxy to make a nice big image of it. (First proper hands on experiment:smile: ).

Anyway that's the basic idea of it but I'm hoping in it to try to find something more specific in it. I've only just started reading into it but is there any interesting properties to go looking for in it? What can it tell us about the galaxy? The rotation curve is part of another experiment so I don't want to go too into that.

Mapping it all is the main part but I'd like to have something more to say about it. Suggestions all very welcome!

Just throwing some ideas: you may want to study the power spectrum of the brightness temperature and its distribution, that can tell you something about the properties of the intergalactic medium, or you may want to study the galactic warp, that can tell you about galactic dynamics.

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...
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...
