Transient Accelerated Expansion and Double Quintessence
, 2004 We consider Double Quintessence models for which the Dark Energy sector consists of two coupled scalar fields. We study in particular the possibility to have a transient acceleration in these models. In both Double Quintessence models studied here, it is

The Zwicky Transient Facility: Surveys and Scheduler [PDF]
Publications of the Astronomical Society of the Pacific, 2019 We present a novel algorithm for scheduling the observations of time-domain imaging surveys. Our integer linear programming approach optimizes an observing plan for an entire night by assigning targets to temporal blocks, enabling strict control of the ...
