I didn't get very good Astro photos (for some reason my brain was mush and totally forgot the camera settings I usually use) but I tried to do some light painting while stargazing in Joshua Tree! (Yes it's a cat)

The first joint ET-LISA Synergy Project is bringing together 40+ scientists to build shared code for joint gravitational-wave analyses. Combining observations across different frequency bands will reveal more about the early Universe than either detector alone. 🔗https://lnkd.in/ds5puvMb

Corner plot and posterior distributions comparing parameter estimation from LISA alone, the Einstein Telescope (ET) alone, and a joint LISA+ET analysis. Blue represents LISA, orange ET, and green the combined analysis. The joint LISA+ET results show substantially narrower posterior distributions for several parameters, illustrating the improved precision achieved through multiband gravitational-wave observations.Conceptual illustration of joint LISA and Einstein Telescope observations of a binary black hole system. Three LISA spacecraft form a triangular laser interferometer in space above Earth, while gravitational-wave ripples extend toward the underground Einstein Telescope facility below the surface. Two black circles represent the binary source. The text “LISA × ET” appears prominently at the top.

Story time! Six years ago, my first book, The End of Everything (Astrophysically Speaking), came out. It was fun to write! I got to share all my cosmology fun facts and dig deep into all the ways the universe might end. I had SO much fun with it, I thought, "maybe I should write another book?" 1/?

Astronomer Vera Rubin was born #OTD in 1928. Her work on galactic rotation curves became one of the main pieces of evidence for the existence of dark matter and she deserved a Nobel Prize for it. 🧪 🔭 ⚛️ 👩‍🔬 Image: Vassar College / Emilio Segrè Visual Archives

Black and white photo of a young Vera Rubin – likely in her teens or twenties – looking through the eyepiece of a long telescope. She wears a blouse or dress with short sleeves and a grid print. Her wavy hair is shoulder length, and there is a wall behind her composed of two-by-fours and wood boards. Her right hand touches the eyepiece, and her left hand is turning a small adjustment knob on the side of the telescope.

Big evidence for “second generation” black hole mergers With 390 gravitational wave events under our belts, we can actually see a difference between spin-orbit aligned and non-aligned mergers. The switch is at 40-45 solar masses. bigthink.com/starts-with-... #blackholes #physics #astro #space

Big evidence for "second generation" black hole mergers

With nearly 400 black hole events from gravitational waves, we can begin to infer their origins. At least two different populations emerge.
