The team identified several lines of evidence in the JWST observations that indicate "little red dot" GLIMPSE-17775 is indeed a black hole star.
When we saw the spectrum for the first time, it was like having all the pieces of a puzzle scattered on the floor. We picked up each piece of the puzzle, measured the lines, and started combining the different pieces into a mosaic. Maybe a few pieces looked like nothing at first, but then a couple of them came together, and we realized that there was something there.
Because GLIMPSE-17775 is surrounded by a massive host galaxy, the "Balmer Break" is weaker in this aspect... thur the additional of team's data:
Everything fits, nothing is broken, and I think that makes the puzzle that is our universe even better. Looking ahead, I’m eager to dive deeper and learn about what is powering the central engines of little red dots. While we think it’s a black hole, there are some other interesting theories being proposed, which is exciting. Maybe in a year or two, we’ll have the final answer to what powers these sources.

New method could reveal hidden supermassive black hole binaries: Bright flashes of lensed starlight guide the way
➡️ https://www.aei.mpg.de/1407139/new-method-could-reveal-hidden-supermassive-black-hole-binaries
📄 https://journals.aps.org/prl/abstract/10.1103/1sfl-87t4 (Open Access)
Researchers at Oxford University and the @mpi_grav in the Potsdam Science Park propose a new way to detect supermassive black hole binaries using gravitational lensing.
Black holes act as natural telescopes, bending light with their gravity. This creates bright images of stars from the same galaxy that lie behind the supermassive black hole binary.
As the binary orbits, it produces repeating flashes of lensed starlight. Wide-field sky surveys may detect these bursts in the future. These bursts can provide information about the black holes’ properties and enabling entirely new studies.

Whooooaaaa! The new #JWST image is so good! So much physics going on — physics Einstein himself thought about!
This is called an Einstein Ring. When a massive foreground galaxy (in this case, an elliptical galaxy) warps the space-time around it, light from behind it bends in our direction.
The JWST caught this fantastic example, where the background spiral galaxy is getting warped into our view. It appears as a ring, but we can see its structures like its spiral arms, gas features and star clusters.
Incredible science happening here!

Euclid opens data treasure trove, offers glimpse of deep fields
➡️ https://www.aei.mpg.de/1240576/euclid-opens-data-treasure-trove-offers-glimpse-of-deep-fields
“Euclid's unique observational capability could help us to better determine the expansion rate of the Universe through gravitational-wave observations,” explains Miguel Zumalacárregui, group leader in the Astrophysical and Cosmological Relativity department at the @mpi_grav in the Potsdam Science Park. To do this, the researchers plan to correlate events from @LIGO, Virgo, and KAGRA with the Euclid galaxy catalogues. Additionally, the large number of gravitational lens systems discovered by Euclid plays an important role. “Euclid observations could also be crucial for detecting the first gravitational waves split into multiple images by gravitational lenses,” adds Zumalacárregui.

J1721+8842 - the first Einstein zig-zag lens: https://arxiv.org/abs/2411.04177 -> First known double #GravitationalLens could shed light on universe’s expansion: https://www.science.org/content/article/first-known-double-gravitational-lens-could-shed-light-universe-s-expansion - zigzagging light bent by perfectly aligned galaxies could improve estimates of Hubble constant (but we aren't there yet).
One of the coolest, most trippy deep-space object is called an Einstein ring. Named for Albert Einstein, who predicted that massive objects in space could magnify or lens the light of objects far behind them, the eerily perfect circle is an illusion created by warped space-time.

Yet, contrary to footnote 13, our local lens props remain invariant bc lens-model-indep. methods can't use redshift info due to the deg. betw. cosmology+lensing and lensing=effective 2d mass from all matter along the line of sight betw. source and obs.

Besides that, this cluster is the first, where we can constrain the smoothness of #DarkMatter without any model directly from the data!

Our merger hypothesis based on ONE multiple-image system and a RedMapper galaxy cluster centre is confirmed! And our analysis remains valid despite updates: 🧶🧶
Since there was a new debate on H0 from lensing on another social media platform, here is your daily reminder to beware of degeneracies:
Call it the mass-sheet degeneracy or the fact that lensing = light deflection of inhomogeneities on top of a cosmic background, the fact that it's ambiguous to chop an integrated signal into an H0-part and a mass-density part makes it hard for strong lensing to probe cosmology...
New paper day! Have a look at

Anybody seen this paper yet? https://arxiv.org/abs/2309.07326
It's about a SN Ia, mapped into multiple images by a foreground galaxy cluster that is an intriguing config itself.
As we already estimated in our paper several years ago (https://arxiv.org/abs/1811.10618) events like this are great to break degeneracies!

Astronomers Find a Rare "Einstein Cross"
Astronomers use powerful gravitational lenses to peer farther into the Universe than they could with their telescopes alone. A foreground galaxy acts as a natural lens for a more distant galaxy, magnifying it and often splitting its light into several versions. When the alignment is almost perfect, the light is split four ways into an "Einstein Cross." Only a few of these have ever been discovered, and now astronomers have found a new one using the Dark Energy Spectroscopic Instrument. It's both beautiful and scientifically valuable for studying the distant Universe.
