Nice to see our research featured by @NASA and @NASAHubble

[NASA @NASA]

A team using @NASAHubble has made the first confirmed detection of a new type of astronomical object: a starless, gas-rich, dark-matter cloud, nicknamed Cloud-9. Here's what this object is teaching us about dark matter and the early universe: https://t.co/csCRXnzgDM

The galaxy, also known as Messier 104, gets its nickname from its central bulge and outer dust trail, which gives it a sombrero-like appearance from our vantage point

py-sphviewer 2.0 is now live on GitHub.

Rebuilt with a novel super fast algorithm. Native C++ multithreading. Native rotations and panning. Deferred Rendering, and more. Is it worth a try? Ask Grok 😉

Astronomers confirm a major prediction of the big bang creation model where dark energy is the universe's dominant component & cold dark matter is the 2nd most abundant component. They found a starless massive gas cloud in M94's halo. The hydrogen gas in this cloud has a mass equal to a million Suns, has a 9,000 light-year diameter, & contains no luminous stars, implying that it is relic gas cloud left over from the cosmic creation event.

If you've ever wondered what Hubble and Webb were observing at any time? 👀

Space Telescope Live can show you what the telescopes are looking at now and what the next planned observation will be, all in one space (pun intended 😁): https://t.co/yOvvSCNYpJ

I had a wonderful interview for Our Narratives, a platform dedicated to sharing original stories, artwork, and research. It was a pleasure to be part of this experience.

Gracias a Alejandro Horvat y a @LANACION por esta nota científica sobre nuestro trabajo!

[Alejandro Benítez-Llambay @bllalejandro]

Another excellent write-up of our results via @SkyandTelescope. Arielle Frommer did a fantastic job summarizing the physics at play and properly contextualizing the alternative interpretations we explored.

[Sky & Telescope @SkyandTelescope]

Astronomers discovered a cloud of hydrogen gas that’s devoid of stars. Held together by an invisible halo of dark matter, the starless cloud may elucidate its nature.

@StartsWithABang has done his homework! The best coverages of our research I’ve read so far. To add to the story: our VLA observations following the FAST detection were crucial. They allowed us to truly pinpoint Cloud-9’s exact location to point Hubble right at it.

[Ethan Siegel @StartsWithABang]

Astronomers are on “Cloud 9” with a new, starless gas cloud

Just 16 million light-years away is a massive cloud of gas, weighing in at around 1.4 million solar masses.

And yet, there are no stars inside at all. Here's what that means.

Scientists trained Hubble’s sharp vision on a starless, gas-rich, dark-matter cloud and identified a new type of astronomical object—a failed galaxy that never produced stars. Nicknamed Cloud-9, it is considered a fossil from the early universe: https://t.co/nxdwdPsSQI #AAS247

Our new paper with @ximexram on a comoving framework for planet migration is on arXiv!

Simulating planets moving through their disk is computationally expensive. Our new method solves this by keeping the planet fixed, making simulations over >10x faster!

[Pablo Benitez Llambay @pabllam]

From preprint to final publication! The journey for this review on planet-disk interaction is complete.

The officially published version is now available online. I hope it serves as a useful resource for the community!

Published version: https://t.co/h9hFtNHdqD

[Alejandro Benítez-Llambay @bllalejandro]

Our new @NASAHubble observations of Cloud-9, an HI cloud near M94, find no galaxy with mass > 3,000 solar masses, making it the strongest candidate yet for a starless dark matter halo, long predicted, but never observed! Exciting! https://t.co/8nhpLhRTcT

¿Es esta la primera imagen de la red cósmica, la colosal telaraña invisible que sostiene al universo? En ella, las galaxias no flotan al azar, sino que se agrupan y conectan a lo largo de filamentos de gas que atraviesan el cosmos como hilos de luz.

This month’s Nature Astronomy cover features our recent paper led by Davide Tornotti, in which we image a filament connecting 2 QSOs. The cover was created in seconds using our new py-sphviewer 2.0 code, which renders N-body simulations with unprecedented spatial dynamic range.

Our April issue is now available to read! The cover image shows the (simulated) filaments of the cosmic web, and comes courtesy of the Tornotti et al. paper within the issue: https://t.co/pVYg5OhZQF
