TL;DR: The observation of DCH states, which exhibit a unique signature, and agreement with theory proves the feasibility of double-core-hole spectroscopy, and exploit the ultrashort pulse duration of the free-electron laser to eject two core electrons on a time scale comparable to that of Auger decay and demonstrate possible future X-ray control of physical inner-shell processes.

TL;DR: The Linac Coherent Light Source (LCLS) and its future plans for the LCLS-II and NGLS are outlined in this article, along with a few selected experiments representing the rapidly developing field of ultra-fast and peak intensity x-ray AMO sciences.

TL;DR: It is discovered that the Auger spectrum as a function of photoexcitation--X-ray-probe delay contains valuable information about the nuclear and electronic degrees of freedom from an element-specific point of view.

TL;DR: In this article, extended x-ray absorption fine structure spectroscopy of liquid microjets has been employed to observe the intermolecular O-O distance undergo a 5.9% expansion at the liquid water interface, in contrast to liquid methanol for which there is a 4.6% surface contraction.

TL;DR: Interpretable diffraction data is recorded from micrometer-sized lipidic sponge phase crystals of the Blastochloris viridis photosynthetic reaction center delivered into an X-FEL beam using a sponge phase micro-jet.
