#aas241 — Public Fediverse posts

Finally put up my #AAS241 swag: magnetic poetry from the GCN & HEASARC!

✨ Starry surprises in NGC 346
🌌 Early "green pea" galaxies discovered
🥇 First exoplanet confirmed by Webb
📀 New infrared look at dusty disk AU Mic
...and more!

#ICYMI, catch up on Webb updates announced during the recent #AAS241 conference here: https://go.nasa.gov/3ZOcjmj

Six negative covid tests since #AAS241... maybe I was lucky enough to have dodged the bullet? (Thank you for the indoor masking policy AAS Leadership!)

Another one of our #JWST #ERS1328 papers hit the arXiv when I was busy with #AAS241 so apologies for the late post -- this one led by Jeff Rich is about the intriguing nature of the nuclear cores in #VV114, complete with #NIRSpec and #MRS SPECTRA!! You know you want to read this for your #JWSTCycle2 proposal... 😉

From Jeff: "We found an AGN where we didn’t expect to, no AGN where others had predicted one, and interesting ISM properties that require a lot more analyses."

Back from #aas241 and still (as of this morning) negative for COVID. So it’s farewell to the grey skies of #Seattle and hello to the wide blue skies of New Mexic… oh
#NMwx #Socorro

The final daily Astro Vlog for #AAS241 is out! Thanks to everyone for watching this year, it sure was fun uploading videos again!

Goodby Seattle! Had a blast at the "Superbowl of Astronomy" the American Astronomical Society meeting #AAS241.

See everyone at #AAS242 in Albuquerque.

Nice to run into the @[email protected] team at #AAS241 - hi @[email protected]!

My photos of #AAS241 at https://planet4589.org/jcm/pics/23/aas/index.html - nice to see @[email protected] @[email protected] @[email protected] @[email protected] @[email protected] @[email protected] @[email protected] @[email protected] among others

@AlicesAstroInfo hello! I hope you enjoyed #AAS241 as much as I did!

A few highlights of #AAS241 and #ALMA were assembled together in our latest newsletter. https://alma.loadingediciones.cl/dev/news/aas/

Overheard while getting coffee after #AAS241:

"You know that astronomy conference that was in town? I read an article that came out of the conference, saying we found galaxies way further than we thought. I just love thinking about how vast space is!"

Agreed.

There was an announcement at the #AAS241 closing ceremony that, as of 5 PM, only one COVID case had been reported among the attendees. Obviously there's going to be a lot of under-reporting, but ... that's pretty good!

Astronomers using @NASAHubble have recorded a star’s final moments as it gets gobbled up by a black hole. Stellar shredding like this happens only a few times in every 100,000 years in any given galaxy with a supermassive black hole center: https://go.nasa.gov/3GLBRrA #AAS241
#NASA

I want to thank the people who pushed to make #AAS241 safer for everyone to attend when the meeting didn’t make mask mandatory at first. The fact that speakers could safely unmask because the rest of the room was masked and well ventilated is a huge step forward. It gives me hope that we can indeed do better as a community. Looking forward to seeing this and daily testing being normalized for future conferences. #PPVII

Back home after a very successful #AAS241 meeting. Web site launch updates to follow over the weekend.

What is the influence of source properties in strong gravitational lensing? Should we extend the formalism to higher orders (flexion) for galaxy-cluster lenses? The answers to these question can be found here: https://doi.org/10.1051/0004-6361/202243562

Sixteen years ago, I chatted with Nobel-winning physicist John Mather about this big project called the James Webb Space Telescope. Now #JWST is a reality - though it took longer than Mather expected - and he's talking about improvements that could be incorporated in future space telescopes. https://cosmiclog.com/2023/01/12/webb-pioneer-gives-advice-to-future-telescope-builders/ #Space #NASA #AAS #AAS241

For the final #AAS241 presser we have the papers https://iopscience.iop.org/article/10.3847/2041-8213/ac9f36 (Live to Die Another Day: The Rebrightening of AT 2018fyk as a Repeating Partial Tidal Disruption Event) and https://www.aanda.org/component/article?access=doi&doi=10.1051/0004-6361/202244805 (Deciphering the extreme X-ray variability of the nuclear transient eRASSt J045650.3−203750) with the releases https://thecollege.syr.edu/news-all/news-2023/a-stars-unexpected-survival/ and https://www.mpe.mpg.de/7920051/news20230112 and https://www.esa.int/Space_in_Member_States/Germany/Schwarze_Loecher_die_immer_wieder_dieselben_Sterne_verschlingen_XMM-Newton_spioniert_sie_aus plus the releases https://cfa.harvard.edu/news/hungry-black-hole-twists-captured-star-donut-shape and https://esahubble.org/images/opo2301a/

A radar view of the Apollo 15 landing site at 1.25-meter resolution! The Lunar Module is in there...but still really hard to spot, since it's just 3 pixels wide. https://public.nrao.edu/news/successful-test-new-planetary-radar/ #Moon #radar #AAS241

Just in time for #AAS241, I want to share an opportunity to learn #datascience techniques for #science --

The #LaSerenaSchoolforDataScience is now accepting applications. It will be back in person in #Chile this year and is open to advanced undergraduates and junior graduate students.

http://lssds.aura-astronomy.org/winter_school/

If you're interested in learning more about possible program outcomes, here's the paper that was developed out of my group's project at the 2021 LSSDS: https://iopscience.iop.org/article/10.3847/1538-3881/ac912a

Last talk for #AAS241

Great quote from @dfm on releasing scientific software as Open Source : "Releasing your code in the open, does not mean your are guaranteed to support it. People can still learn from it. But maintaining it can lead to higher impact."

#AAS241 #OpenScience

Attended my first science talk at #AAS241, which happened to be my own. Thanks to Grant Tremblay for the photo that makes me look like a plenary speaker. #Astrodon

Had a very #HarryPotter moment trying to find the link rail station which was supposed to be right there according to the map but the building just appeared abandoned and inaccessible to #muggles.

Thanks for a great conference #AAS241! My heart has already gotten ahead of me back to the kiddos.

Doing some last minute touch ups on my #AAS241 talk this afternoon. Five minutes really is not enough time for a research talk, and I think this might be the last AAS talk I give for a long time. Particularly being in the afternoon session of the last day, when I need to be tearing down our booth and when most of my friends have said "oh, sorry, I'll be gone by then," the effort-to-return ratio is, pardon the pun, astronomical. #AstroChatter #Astrodon

I had meant to advertise UCI grad Raymond Remigio's #AAS241 poster (360.15) but failed to do so in advance. Turns out he didn't need much advertising after all - there's always a crowd! Check out the cool video on his poster 😊 #ProudMentor

When else would your #JWSTlaunch baby take her first steps but when you're away at a conference #AAS241?!? Good thing there's a video clip of it... 🥲

(apologies to dinner companions for the silly grin on my face while I stared at my phone for 50 seconds)

Venkatesan now wrapping with thanks to the audience and the #LPRISD Committee for a successful, first-ever hybrid splinter session. Notes that many of the concerns discussed today are expected to accelerate in 2023, and invites AAS members to join the group. #AAS241

Q: About diffuse brightness of the night sky due to satellites and space debris, has it been observed or are there efforts to detect it?

Green: It's "fiendishly difficult" to try to measure it because the light is distributed over the whole sky. It hasn't been measured to date.

#AAS241 #LPRISD

Q: Any concerns about satellite direct-to-mobile communications?

C. Walker: The giant antenna sizes (e.g., #BlueWalker3) are concerning in terms of optical/IR brightness. Obvious radio interference concerns as well, but may possibly be mitigated.

#AAS241 #LPRISD

Q: What about the potential connections to climate?

J. McDowell: Although traffic in space is going way up, it's very small compared to what we're putting in the oceans. But total mass of the upper atmosphere is tiny, so re-entries can have an outsized effect.

#AAS241 #LPRISD

Heim: It's not just whether we can see the stars. There are other, tangible threats to humanity both in space and on Earth that result from the rapid commercialization of space with few meaningful rules for how that space is used. #AAS241 #LPRISD

Heim: Not only satellites, but also ground-based light pollution have a real affect on how people experience the night sky, threatening to cut humanity off from one of the oldest environmental influences in our long history. #AAS241 #LPRISD

Heim: While there's no doubt that access to broadband Internet has significant social benefits, the way it is delivered (especially from space) and how that impacts the environment consists of a series of unanswered questions. #AAS241 #LPRISD

The last speaker is Jessica Heim (University of Southern Queensland) and co-chair of the #LPRISD Community Engagement subcommittee talking about the cultural affects of satellite megaconstellations. #AAS241

Arion: Most of these environmental concerns aren't attributable to big, single problems. It's lots of smaller problems that add up in aggregate. We need to work more closely with enviro orgs that have "deep pockets" and care about the bigger picture. #AAS241 #LPRISD

Arion pivots to remind the audience that, meanwhile, we still haven't solved the problem of terrestrial light pollution. Many of the effects are "upstream" of the light sources, like carbon emissions from wasted light associated with electricity production. #AAS241 #LPRISD

Arion: We're also polluting the surfaces of other Solar System bodies that will persist in their environments for "a very, very long time". Launches from those places can contaminate their surfaces/atmospheres more broadly. #AAS241 #LPRISD

Arion: It's not just about what happens in space. There's a whole life cycle of space operations from launch to re-entry that can have harmful environmental effects. This impacts launch sites to the upper atmosphere. #AAS241 #LPRISD

The next presenter is Doug Arion (Carthage College, emeritus) on the associated environmental and ecological concerns relating to large satellite constellations. #AAS241 #LPRISD

Mudd: Recent litigation has addressed some of these issues. U.S. federal courts have consolidated some of the recent cases. "We need a lot more than these regulations." Stay tuned! #AAS241 #LPRISD
