Hello to everyone at AAS High Energy #HEAD20! The Chandra X-Ray Center is happy to have a booth, and we hope you swing by to say hi, pick up some swag, and ask whatever questions you have -- from how to get started with Chandra data to the nuances of your most complex analyses!

We've had booths at conferences around the world, but this might be a first for us: a view from the booth toward a family of dolphins playing in a lagoon! If you're at #HEAD20, come swing by our booth on the Grand Promenade and see the view for yourself!

The Chandra Observatory team is happy to be a part of the AAS High Energy and to be present at #HEAD20. Not only can you stop by our booth, but many of us are here as well -- reach out with your Chandra questions! We gathered for this photo just before Mark Bautz's Innovation Prize Talk.

Hi #HEAD20! It's your last chance to visit the booth and grab some of the great swag we have available. Today is also the day to learn more about the Chandra Source Catalog! There's a hands-on tutorial (with lunch) at 12:30 and a Special Session at 2 PM! submissions.mirasmart.com/HEAD20/Itinera…

The pizza is here! If you're at #HEAD20, come to Kona 4 to have a slice and get some hands-on experience working with the Chandra Source Catalog in time for the release of Version 2.1! And if you're attending remotely, the Zoom info is on the Conference Slack #XRaysAreTheBestRays

Interested in High Resolution X-Ray Spectroscopy? That will be the theme of our summer workshop, to be held online and on MIT's campus (Cambridge, MA) from Aug 1-3. The abstract submission deadline is coming up, so submit yours now! cxc.harvard.edu/cdo/hrxs2023/ #XRaysAreTheBestRays

Hello American Physical Society! We're excited to have a presence at the meeting. If you're in Minneapolis, come by and learn about the observatory and our mission and collect some swag -- or, like these Drake University students, get your photo with Chandra! #APSApril #XRaysAreTheBestRays

It's Throwback Monday at #APSApril: Last year Chad Kishimoto (Chad Kishimoto) and his students came by our booth, and this year the tradition continued! We're looking forward to seeing @usdcas students again next year at the @APSMeetings April Meeting!

Are you at #AAS242? Be sure to swing by the #ChandraXray booth every day -- we have limited edition buttons for each day of the conference. Today's button: nearby spiral M101. With our excellent angular resolution, we see where in M101 energetic events are happening!

Hello #AAS242 -- join us at 9:30 in the Exhibitor Theater for a presentation by Ian Evans on the Chandra Observatory Source Catalog. The CSC and its upcoming 2.1 release unlock the 24-year legacy of our mission to enable everyone -- yes, everyone! -- to be an X-ray expert.

Our #AAS242 booth is now packed up and ready for the trip home, but we wanted to thank everyone who stopped by; whether you were learning about us for the first time or are a long-time user, it was lovely to meet with and chat with you all. See you in New Orleans for #AAS243!
