OK, wrapping up #Swift15. Thanks to @reginacaputo and @JoshuaSchlieder for help with all the Tweets. We'll leave you all with the 10 year anniversary video (new one coming next year!) and looking forward to many more years of discovery and exploration.

And of course Swift is much more than just GRBs and supernovae. Here are a few representative examples of some of the broad science the community is undertaking for #Swift15Science: Hot, young and blue stars sparkle in Swift’s ultraviolet view of our neighbor the Andromeda galaxy

Did you know that Swift studies exoplanet systems? Here's an X-ray flare from the host star (HD 189733b) of a hot-Jupiter just before it transits #Swift15Science

And even closer to home - comets! Swift and @NASAHubble caught a brightening from Asteroid Scheila after it collided with a smaller asteroid.

More fun cosmic explosions for #Swift15Science 🎇🧨🎆 -
Swift J1644 57: an unlucky star wanders too close to a supermassive black hole and is shredded to bits. The resulting tidal disruption event also marks the birth of a relativistic jet.

AT2018cow: A mysterious “cow” observed by Swift explodes 10 times brighter than a typical supernova. 🐮🐄🐮

ASASSN-15lh: A mysterious transient from @SuperASASSN. The most luminous supernova yet discovered? An extremely energetic tidal disruption event? The jury may still be out on this one ...

Some more fun GRB science for #Swift15Science - Still the most distant (spectroscopically confirmed) GRB at z = 8.2, when the Universe was just 600 million years old and around the time that reionization was taking place, GRB090423.

GRB060218 - Still the second nearest GRB detected by Swift, joint observations by the XRT and UVOT captured the prompt "shock breakout" of the progenitor star, as well as the associated H- and He-poor supernova SN2006aj (Figure from Campana et al. 2006).

More GRB #Swift15Science - a new class of ultra-long (> 10,000 s) GRBs, possibly powered by the explosion of blue supergiant stars.

Some #Swift15Science to wrap up our 15th "birthday" - the association between short-duration gamma-ray bursts and binary neutron star mergers. This was a decade effort leading up to the multi-messenger era - let's walk through some of the key results ...

Guided by our theorist friends, we searched for the smoking gun signature of binary neutron star mergers - the formation of heavy r-process elements in a rebrightening known as a kilonova. Tantalizing evidence came from a Swift-detected GRB in 2013 ...

And the final irrefutable evidence came from the joint detection of gravitational waves (@LIGO and @ego_virgo) and a gamma-ray burst (@NASAFermi and @ESA_Integral) from GW170817. Definitely the most remarkable cosmic fireworks show we've seen 🎆🧨🎇!

And now, for #Swift15 some science highlights from the last 15 years. It's critical to note that Swift doesn't exist in a vacuum, but is part of a portfolio of facilities in space (@NASAFermi, @chandraxray, @NASANuSTAR, @NASAHubble, @NASA_TESS, @ESA_XMM, @ESA_Integral) ...

and on the ground (@SuperASASSN, @ztfsurvey, @PanSTARRS1, @fallingstarIfA, @MAGICtelescopes, @VeritasGammaRay, @hesstelescopes, @LIGO, @ego_virgo, @uw_icecube, and too many others to mention). We wouldn't be anywhere near as scientifically productive without such great friends!
