This poster by Shifra Mandel focuses on what HEX-P will enable in the Galactic Center. There is a cornucopia of sources there, both point sources and diffuse, as well as flares from Sgr A* -- the hiccups of the supermassive black hole! #HEAD20

Here's another poster from #HEAD20, this one from Matteo Bachetti. He simulated how HEX-P will enable exceptional new studies of ULXs -- with the resolution needed to separate sources, the sensitivity to detect them in short exposures, and the bandpass to see new behaviors.

Here's a poster from @amruta, on how HEX-P will change our understanding of pulsars. HEX-P will allow us to detect and study pulsars in crowded environments, and to study geometries of intra-binary shocks. We'll learn about companion ablation and orbital evolution. #HEAD20

Oh no, the posters are coming down and we still have so many to share! Here's one from Suvi Gezari, with a conversation with Chat-HEX-P on the potentials of X-ray spectro-timing of extragalactic nuclear transients #HEAD20 #HEXPloreTheUniverse

.@ArcodiaRiccardo gives the last of the @eROSITA_SRG talks of the #HEAD20 meeting on tidal distributing events and the discovery potential of @eROSITA_SRG on variable sources. Riccardo presents lots of great work done by @adam_malyali and Zhu Liu.

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

Here's Dan Wilkins with his poster on the HEX-P perspective on AGN. These observations will revolutionize our understanding of supermassive black hole growth and the important effect that these objects have on their host galaxies and the formation of structure in the Universe. #HEAD20

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; https://submissions.mirasmart.com/HEAD20/Itinerary/EventDetail.aspx?evt=19) at 12:30 and a Special Session at 2 PM (https://submissions.mirasmart.com/HEAD20/Itinerary/EventDetail.aspx?evt=5)!

#HEAD20 isn't over yet, and we still have posters to share! Nicole Rodriguez Cavero demonstrates how the highest-energy sensitivities of HEX-P will enable us to discern coronal geometries generated from the kerrC relativistic ray-tracing code.

Daniel finishes with a shoutout to all of the 22 HEX-P posters. If you're in Hawaii, please take a look at them! And, if you're not -- well, we'll keep on posting them for your benefit on the #HEAD20 hashtag!

HEX-P will enable fundamental insights into the Physics of Accretion -- jet physics, coronal physics, black hole growth and spin, neutron star radius and physics, as well as accretion disk modeling and truncation #HEAD20

The Cosmic X-Ray Background was a motivation for Chandra and XMM -- but we can't extrapolate low energy results. NuSTAR got us to ~10% of this high energy background -- we'll get this over 60%! We'll go over an order of magnitude deeper than the deepest NuSTAR surveys. #HEAD20

HEX-P will introduce a new era in >10 keV imaging. As we've shown here several times this week, we'll be able to resolve galactic populations -- at a level beyond 10 keV, where all the information needed to discriminate between models lies. #HEAD20

Our mission structure is to have a low energy telescope (HPD = 5 arcsec) covering 0.2 - 25 keV, and 2 high energy telescopes (HPD 10 arcsec) covering 2-80 keV. To get the best effective area at high energies, we have a 20 meter focal length, benefiting low energies as well! #HEAD20

HEX-P science is centered around four pillars: a complete census of black hole growth, the extreme physics of accreting objects, resolved populations in the local universe, and the dynamic universe. We need high energies to understand these. #HEAD20

Daniel Stern has taken the stage at #HEAD20 to talk about the vision of the HEX-P Future.

If you're at #HEAD20, make your way over to the Monarchy ballroom -- we're about to have our HEX-P talk in the session on the APEX probes!

Andrew West has a #HEAD20 poster: when a tearing event occurs in a highly-inclined accretion disk, jet formation can occur. Raytracing simulations of these events shows that HEX-P can use Fe line variability to constrain subtle features of these events.

I never tire of hearing hair-raising ballooning stories--leaky balloons, Antarctic crevasse recoveries, broken detectors and switches, data buried in the ice for two years... (B. Rauch on SuperTIGRE at #HEAD20.)

We are celebrating a giant in the field of astrophysics today. Mark Bautz @mwbautz of @MIT received the #HEAD20 Innovation Prize this year. I always felt fortunate to have had the opportunity to work with him. Below, he is with his four generations of grateful postdocs
