International Day of Women and Girls in Science!

Just sharing this as it appeared in their Mastodon post.

MPI for Gravitational Physics @mpi_grav@astrodon.social

As a reminder, today is the last day of our female researcher portrait to celebrate the International Day of Women and Girls in Science!

But until the end of the month, we will be sharing our colleagues' advice for young women, their paths to physics, and their visions for the future.

Possible Gravitational wave detected by LIGO

This is quoted from a Mastodon post from the MPI for Gravitational Physics

Last night, the two @LIGO detectors observed the second gravitational-wave candidate of the day.

The possible signal with the preliminary designation S250205ee most likely originates – if it is real – from the merger of two black holes.

It occurred at a (luminosity) distance of 9.4 billion light-years.

This brings the total number of significant signal candidates identified in the fourth joint observation run of the international detector network to 190. One (GW230529) has already been fully analyzed and published. The others will also be carefully examined and then published if confirmed.

What is Space-Time?

So back to some Physics videos, what is space-time?: This video does a really nice job of explaining this in a way that is understandable, but not so simple it loses any meaning.

I have included links to wondorium below, as well as links to the usual discussion forums.

Unsolved problems in cosmology

I decided to sign up to another free open learn course with the Open University. Unsolved problems in cosmology is an extract from a level 3 course, S385 Cosmology and the distant Universe.

After studying this course, you should be able to:

• understand the basis of modern cosmology based on the hot big bang
• summarise the main candidate dark matter particles, and the prospects for directly detecting them
• compare models to explain the late-time acceleration of the Universe's expansion, i.e. dark energy and the cosmological constant
• discuss observational prospects for understanding the nature of dark energy
• explain the theoretical problems that led to the theory of inflation, how an early inflationary period solves them, and how researchers are investigating inflation.

Dust Battery

More interesting findings about the early universe, I guess some of this makes sense as one of the 4 fundamental forces is Electromagnetic forces.

This research findings are detailed here. So if I understand this correctly, the early universe processes had that were had electrically charged dust particles, these produced magnetic fields as they moved around by the radiation from the 2nd generation of stars.

There is a related paper on arXiv on this research.

Future space telescopes

Future space telescopes could be made from thin membranes, unrolled in space to enormous size

Interesting article on the future of space telescopes so the idea seems interesting as it allows deployment of large telescopes in space quickly.

The JWST is 6.5 meters, the ELT is 39 meters (ground based) as the JWST is foldable then the technology is already there.

This could offer some real opportunity to make strides forward, as we have seen with the JWST. Larger telescopes allow for the collection of more light, I would guess that telescopes can be built to collect different light e.g. UV, Visible and IR.

Should be good.

Black Hole Tears Star to Shreds, Unleashing Cosmic Shockwaves

Black Hole Tears Star to Shreds, Unleashing Cosmic Shockwaves

This is interesting, I will add a link to NICER (see article) to the links page.

Black holes seem really complex, and there is probably much more to learn. It is also worth watching the two videos as a further explainer to the research and the resulting paper.

So this is looking at a black hole, and how it is interacting with a local star trapped within its gravitational pull, As the star is pulled apart, some of the matter becomes a disk around the black hole, however this matter is then also interacting with another star.

If I understand the paper or at least article, this event links tidal disruption events * and quasi-periodic eruptions, helping astronomers understand black hole environments and shape future research

• The above link is to Wikipedia, as this is NOT an academic source of information, please use a different source, link is for reference only

On an unrelated note, according to the Solar System series by Professor Brian COX, Rings have formed around planets when an object such as an asteroid gets caught in the gravitational pull of the planet, Moons are also objects that have been caught up.

I am not sure if the two phenomenons are related in that stars being ripped apart by a black hole are a similar event, just on a much larger scale.

According to MIT there have been other similar events detailed here

New Superheavy Element Synthesis

Updated and reposted 5/11/2024

Interesting post found on Matrix today, :-

New Superheavy Element Synthesis Points to Long-Sought ‘Island of Stability’ you can read more about this in the scientific American article published on 24th September

Seems interesting, as I read a paper a few years ago suggesting element 120 was present in Przybylski's Star. In fact, a number of papers on arXiv have suggested some interesting properties and chemistry.

Here is a link to the Matrix Physics Room where I found the link mentioned above

Update

There is now an update to this research

While I acknowledge that wikipedia is not an academic source of information there is a page on the island of stability as related to nuclear physics that may be useful here.

Open Day at GEO600

This was posted to the MPI for Gravitational Physics Fediverse account today. There is an open day at the Gravitational wave detector on the 31st August, so just sharing here.

Further details can be found here. I have quoted some of the text from the above site below.

Open Day at GEO600

Visit the gravitational-wave detector near Sarstedt on 31 August 2024

On Saturday, August 31, 2024, the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) and the Institute for Gravitational Physics of Leibniz Universität Hannover invite you to visit the German-British gravitational-wave detector GEO600 near Sarstedt. Between 12:00 and 16:00 CEST, visitors can speak with researchers at the detector site about the current state of gravitational-wave astronomy, the crucial contributions of GEO600 as a think tank of international research, and visit the detector.
