Twitter Web App : OK, wrapping up #Swift15. Thanks to Regina Caputo and Joshua Schlieder 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.

Twitter Web App : And even closer to home - comets! Swift and Hubble caught a brightening from Asteroid Scheila after it collided with a smaller asteroid.

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

Twitter Web App : Mega-flares from a mini-star: Don’t let the small size fool you, Swift caught a flare from a nearby red dwarf which was 10,000 times more powerful than anything we’ve observed from our sun!

Twitter Web App : 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

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

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

Twitter Web App : SN2008D: For the first time, Swift serendipitously caught a supernova explosion as it was happening ⭐️🧨🎇

Twitter Web App : 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.

Twitter Web App : Judy Racusin 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).

Twitter Web App : GRB080319B - A rapidly rotating massive star explodes into a gamma-ray burst so bright you could have seen it with just your eyes! The naked eye burst is still the brightest afterglow Swift has seen since launch Judy Racusin #Swift15Science

svs.gsfc.nasa.gov/10369

Twitter Web App : 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.

en.wikipedia.org/wiki/GRB_090423

Twitter Web App : 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 🎆🧨🎇!

Twitter Web App : 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 ...

Twitter Web App : Over the next decade the accumulation of more afterglows strongly supported an older progenitor system, and the locations of these afterglows *within* their host galaxies were consistent with predictions for binary neutron star mergers (figure from Fong et al. 2013) ...

Twitter Web App : The first afterglow - and hence host galaxy - detection for a bona fide short GRB was from GRB050509B. The likely host galaxy - a massive elliptical - was unlike any of the star-forming galaxies in which long GRBs occur ...

Twitter Web App : 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 ...
