2011 DOE Reviewer IssuesDo we play well with the Particle Theory Group?!!Interactions between two groups occur daily.!!1-3 postdocs in intersection areas have been on staff since 2000.!!However our contribution to Fermilab’s research program is clearly differentiated from Particle Theory (we mostly benefit Cosmic Frontier).!!Are we aligned with DOE HEP mission?!

2014 P5 report supports current and planned effort.

7/30/1417


Current Program well aligned with P5 prioritiesP5 Report 22 May 2014 "!Essential Roles of … Theory (slide 25)"“… A thriving theory program is essential for both identifying new directions for the field and supporting the current experimental program …”

Recommendation 16: Build DESI as a major step forward in dark energy science …!Recommendation 17: Complete LSST as planned.!Recommendation 18: Support CMB as part of the core particle physics program!Recommendation 19: Proceed w/ G2 dark matter direct detection program !Recommendation 20: Support one or more G3 direct detection experiments !Recommendation 21: Invest in Cerenkov Telescope Array

Recommendation 29: Strengthen laboratory university cooperation to address computing/software needs !! (Cosmological Computing Initiative, COSMOSIS: see Gnedin’s presentation)

Summary

7/30/1419

§ Theoretical Astrophysics was/is/will be essential for vibrant Cosmic Frontier Program! !Ø current / past projects have grown out of theory program !

Ø broader community benefits!!§ Benefits to Fermilab program. !

Ø proximity to experiment(alist)s cross-fertilizes both theoretical and experimental FNAL research.!

Ø enlivens intellectual atmosphere @ FNAL and elsewhere!• visitors, seminars, workshops, conferences!

§ Strong record of service to the US & international community. !§ High productivity!

★ ~ 50 papers / year!★ ~ 1 postdoc / year (currently, funding limited)!★ ~ 3 Ph.D trained/ year (funded outside of DOE)!★ ~ 3 workshops / year!★ ~ 1.5 future faculty / year (historically)!

§ Alignment w/ P5 priorities
