=== Neil Cornish - taking templates off the grid ===

- Can't do grids for many parameters; MCMC instead
- Actually it's MHMC, use heating, freezing

- First application: single Galactic binary
- Non-spinning BHs
- Galactic foreground (within 20% of theoretical limit for Challenge 2)
- Problems with secondary maxima in all parameter slicings
- Especially true for EMRIs
	- Implemented mode jumping: jump-explore-select (extreme illegal delayed rejection)
- EMRIs: our monster
	- Shotgun approach: short chains on 3 months
	- Sequence of zoomed-in searches
	- New band-jumping move from structure of EMRI harmonics

- Gridless searches for complex, high-dimensional searches

=== Jonathan Gair - Metropolis-Hastings Monte Carlo search for extreme--mass-ratio inspirals ===

- Intro to EMRIs, MCMC issues
- Identifying EMRI harmonic structure
	- Chains lock quickly
	- Analyze overlap contributed by each harmonic
		- See which harmonics contributed SNR where
	- Use to provide starting points for chains
	- Use as veto for secondaries
 	- Fold into parameter priors
	- Use as constraint for Monte Carlo search by proposing jumps that respect constraints
		- Improvements limited because of poor frequency determination
- In the future
	- More harmonic finding
	- Fast-waveform model
	- Real LISA problem more complicated: how to identify harmonics from same source? Explore in future challenges.
