Assessing how the lenses we found compare with expectations from forecasts: arxiv.org/abs/2503.08785

Our most spectacular lenses: arxiv.org/abs/2503.08782

Announcing the COSMOS-Web Lens Survey, over 100 strong gravitational lenses discovered with JWST! Survey overview: arxiv.org/abs/2503.08777

@juliangough @GravityGrinch Most likely a selection effect rather than physics: we probably missed some faint/high redshift lenses during the visual inspection, since these are the hardest to spot. Also, some of the lower-scoring (faint) candidates I excluded from the comparison are potentially true lenses.

@GravityGrinch @astronat Very interesting. “The observed lens redshift distribution peaks at a slightly lower redshift than the forecast one, whilst the lens magnitudes are systematically brighter in the observed data than in the forecast.” How do you interpret that? What’s it revealing?

That's quite an interesting read today: new lensing survey data released with 100 strong-lensing galaxy-scale cases: arxiv.org/abs/2503.08777 arxiv.org/abs/2503.08782 arxiv.org/abs/2503.08785 (congrats @astronat !)

@GravityGrinch Coming from Oxford as I do, perhaps the mystique will be slightly less apparent ;) I'll be joining Will Handley's group at the IoA!

@astronat 😊😊😊 Enjoy! For me, it looked like Harry-Potter-Town, magic around every corner. But it's also Dennis Sciama's university. So big history in cosmology there! Who will you be working with?

I'm elated to share that in October I'll be moving to Cambridge for another 4 years of postdoc! There isn't room in a tweet to describe how much this means to me; suffice to say, I'm extremely happy.

@GravityGrinch Thanks Jenny! The original Cambridge ;)

@astronat Cordial congrats!! That sounds terrific! 🍾🍾🍾 But wait, which Cambridge? UK or US? (however, both are great places for science 😁)

@JSMakechemu Thanks Jason! Actually, looking at the programme, NAM 2025 looks pretty tempting!

I often find myself listening to Schubert's "Winterreise" when I'm feeling a bit low. I guess it's because the thought that there's some poor bastard out there who feels even lower offers some degree of comfort.

Join a choir today!

Does astrology work? We tested the ability of 152 astrologers to see if they could demonstrate genuine astrological skill. Here is how the study was designed and what we found (including a result that really surprised me): 🧵

Marie Curie did not have to fit 9 deliverabkes, 17 milestones and 44 tasks in a 24 months gantt chart as we, who got the grant in her name, have to do

Taking a moment to enjoy the fact that the new PM was an exhibitioner at Junior Guildhall, who played loads of instruments growing up, who says his favourite music is Beethoven sonatas.

THEY HAVE NOW

The Greens now have as many seats as Reform. Will they get anywhere near as much press coverage?

We had a blast performing Haydn's Creation with the @LPChoir back in March and can think of no better way to round off a sunny Saturday than with a snippet from the glorious 'Awake the harp' chorus 🌞 Head over to @MarqueeArtsTV to watch the whole performance!

Going to do a post doc in a different field

WATCH: 🗳️🔴 @Keir_Starmer confirms to me Labour will extend voting rights to 16-17 year olds if elected "If you can work, if you can pay tax, if you can serve in your armed forces, then you ought to be able to vote."

@cosmic_mar More on the astro than cosmo side, but there's ShOpt.jl by Eddie Berman and Jacqueline McCleary for JWST PSF characterisation: arxiv.org/abs/2310.00071

hey #JuliaLang folks, I'm helping put together a list of Julia cosmology-related packages for NASA Lambda, wacha got? (please dont hesitate to point me to your own!) 👇
