@franco_vazza Yup, that's all it is. Someone made a joke that the second version should be called The Next Generation, and two decades of astronomers have been gifted a three-character command line task as a consequence of the consequence.

Finally -- a note on the newsletter. All the articles here were written by CXC staff members. But if you read the fine print at the bottom of the newsletter: "We welcome contributions from readers."

We aren't astrobites, so this isn't for summarizing your paper, but if you have something a little bigger than that: reach out! I'm the editor, and, if you're reading this, you know how to get in contact with me. I'd be happy to have more variety now that I'm in charge!

Finally, the article on Peer Review. It has all the numbers you could want (how many proposals, acceptance rates), but it also talks a bit about Dual Anonymous Peer Review (#DAPR). DAPR is here to stay, and the consequences of violating the rules are a rejected proposal. Luckily, the rules are very easy to hold to, and Rudy Montez gives some great examples. If you're a CXO observer, or planning on being one in the future, I strongly recommend giving this a read.

But the changes to DS9 are more than just cosmetic. You can plot your own catalogs directly onto an image; you can read FITS tables, plot columns, and bin those columns into images; you can pull down the footprints of Chandra observations to see if your target has been observed (and hopefully other observatories will enable support for this, too!). But, maybe most exciting of all for the modern astronomer: make your data cubes into movies, easy (like so)!

The next article is a doozy, and it's going to get two toots. Most professional astronomers use ds9 in some form or another. And many know that the story of the name: SAOImage was first, and a second version was SAOImageTNG (the next generation). So the followup was SAOImageDS9 (ask a #StarTrek fan if you don't get it). And, unlike the other two, DS9 has stuck around since 1999 -- but not without updates! First off: there's now a dark mode! And an advanced view, with power at your fingertips.

We then turn to the workshop. Every year, Chandra hosts a workshop on related science. We'll be doing it again this summer (ask me how I know ;) ). This year, the workshop was on #supernova remnants and their progenitors. Dan Patnaude, co-chair of the SOC, provides a rundown of all the fun science that was discussed, including his own, personal highlights. If you missed the workshop, don't fear! The talks are all available on Youtube: https://youtube.com/playlist?list=PLHL ab1XaRRMLOuoZ0r_bnCsrtNCA1-WWI

A logo for a conference, labeled "Supernova remnants and their progenitors." The logo is an outline of the Chandra X-ray Observatory surrounded by four concentric circles, with a rectangular grid seen in projection at the bottom. Blobs are seen along the outer most rings; the colors are mostly black and purple, but rise to orange and yellow at the peaks of the blobs.

Our next story is the cover story: how sonifications made some data from 2003 blow up across social and traditional media almost twenty years later. I can't do the full story justice in one toot, but it's a fascinating look into how #ScienceOutreach, #Accessibility, and #DataVisualization combined with some strange timing can really help #Science stories go viral. Read the whole story here: https://cxc.cfa.harvard.edu/newsletter s/news_32/article4.html, but also check out the sonification that started it all: https://chandra.si.edu/photo/2022/soni fy5/

A pink and purple blob, reminiscent of bubbles rising up into a sink, as viewed from above. A thin beam stretches out from the center, at a slight angle to the bottom. Across the bottom is a bar composed of individual vertical bars, each of different heights, mapping the volume at different frequencies. Over top of all of this are a number of the Red Hearts and Green Retweets associated with Twitter.

The next article is from the Chandra Source Catalog team. The CSC is a *phenomenal* resource for people trying to do population studies, or who have a source they're interested in at different wavelengths and want the X-ray perspective. The upcoming 2.1 release is going to dramatically improve sky coverage and source numbers, while also aligning positions to the Gaia frame. All with better fluxes for faint and crowded sources. Data are available NOW!

The first article is from Raffaele D'Abrusco and is about the Chandra Data Archive. Did you know you can (and should) cite Chandra ObsIDs? They have their own DOIs! In AASTex, just use \dataset[ObsID]{https://doi.org/10.25574/ObsID}

Or maybe you're interested in Transient phenomena; did you know the CXC archive is now cross-linking with ZTF alerts? This is a pilot for upcoming integrations with the archive, maximizing the use of our second, "phantom" telescope.

A cover of a periodical, like a magazine. The title reads "Chandra News," with a date of "Issue 32 -- Fall 2022." The title story is "Sonifications Bring New Life to Old Sounds" by Kimberly Arcand & Megan Watzke. The cover image is a pink-and-purple blob of gas (the Perseus cluster, to those who know), with a vertical, glowing line sticking up from the middle and a horizontal sound bar at the bottom of the frame."

It's Alt Time! @thomasconnor@mstdn.social is my main account, but this will be where I focus on astronomy. Less humor and hobbies, more #Astrodon

I'm an astrophysicist at the CfA at #Harvard, where I work in the #Chandra Director's Office. Before that, I was at #JPL / #Caltech / Carnegie. I study the highest redshift quasars, primarily in the X-rays. I can never remember if I'm an X-ray astronomer or a ground-based observer. I also do galaxy cluster stuff and think about observing techniques. #Introductions
