A RAS Specialist Discussion Meeting organised by *Robert Crittenden (Portsmouth);
Alkistis Pourtsidou (Portsmouth); Clive Dickinson (Manchester)

*Contact: robert.crittenden@port.ac.uk

Please note the meeting is a week earlier than usual due to Good Friday bank holiday, and has earlier start and finish times.

 

In the next few years, optical galaxy surveys like the DES, Euclid, and LSST, are promising to deliver cosmological measurements of unprecedented statistical precision. At the same time, the novel and very promising intensity mapping technique is going to be tested with instruments like BINGO and CHIME, as well as with the SKA and its pathfinders (MeerKAT). Combining the two methods (and CMB observations) can alleviate important problems like systematics and foreground contamination, and achieve powerful cosmological constraints. The meeting will discuss the possible synergies and describe how they can be used to investigate the causes of cosmic acceleration via dark energy and gravity tests.
