Here's a really nice introduction article to the #astronomy field of research I am currently working in.

You've heard of Gravitational Waves (GWs) - but did you also know there is a GW spectrum - and much like the EM spectrum, different sources produce different frequencies of GWs.

The GWs we've so far discovered are generated by stellar mass black holes and neutron stars, but the research I am involved with is searching for GWs generated by supermassive black holes (SMBHs) - found in the hearts of galaxies. These SMBHs give off their gravitational radiation as galaxies merge and collide.

Though these are nanohertz frequencies and have wave periods lasting not seconds, but decades! So, we can't use terrestrial detectors to discover them. Instead, we use pulsars located around the Galaxy - each as an analogue to a giant interferometer arm.

This Thursday I am submitting my Master's Thesis on this very topic! For the last 12 months I have assessed 10 new millisecond pulsars to see how they improve the Parkes Pulsar Timing Array's sensitivity to detecting these GWs.

Hello! It's great to be here. I'm a PhD student at Rutgers at the moment, and this will be my "very professional" mastodon account! I'm currently working with moon rocks, specifically meteorites, specifically-specifically lunar breccias.

Look up tonight! The Northern Taurid #meteor shower is expected to peak with the possibility of #fireballs. More on EarthSky: https://earthsky.org/astronomy-essentials/taurid-meteors-all-you-need-to-know/ and SPACE.com: https://www.space.com/nothern-taurid-meteor-shower-peaks-saturday-nov-12-2022

It's not the most active shower of the year, but you might get lucky if you have very dark skies and clear weather 🌠 #meteorshower #taurids #cometencke #skywatching

#HIP41378 f THIS IS TONIGHT !!

The #night has already started in Europe. Current #weather status is:

- OHP ❌
- Calar Alto ✅
- La Palma ❌

But the weather in Chile is great ! ✅

Reading about the Middle Ages is like reading about an alien world where everything is familiar.

I recommend it.

For the full “Ambition” experience, I recommend watching the teaser trailer, released without any hint that it was linked to Rosetta or ESA, then the main film, & finally the epilogue released in September 2016, when the mission ended with Rosetta’s impact on 67P/C-G.

#OTD eight years ago, the Philae lander left the Rosetta spacecraft & headed towards the surface of Comet 67P/Churyumov-Gerasimenko.

Some of the rationale for this astonishing European Space Agency mission with its huge technological, operational, & scientific challenges is captured in the short sci-fi film we made with Platige Image, not least in the title: “Ambition”.

Such a privilege to have been involved with such an amazing team 🙇‍♂️

Undetected Black Hole Reveals Itself by Violently Shredding a Star That Strayed Too Close https://scitechdaily.com/undetected-black-hole-reveals-itself-by-violently-shredding-a-star-that-strayed-too-close/

We should continue trying to convince our colleagues to come over here (on #Mastodon), and not spread around on many different apps.

We should also promote the work of PhD students and #ECR, by boosting their toots 🔄. It is important for their careers !

I just created an AsyncAPI #Mastodon server: asyncapi.social. Would you mind boosting this toot so it helps federating with other servers? Thanks 🙏

2500 years after Thales of Miletus described static electricity, physicists are still trying to figure out exactly how it works. https://nationalmaglab.org/education/magnet-academy/history-of-electricity-magnetism/timeline/600-bc-1599 #physics #History
