Jens Hjorth Dark Cosmology Centre (2005–2015) Niels Bohr Institute, U Copenhagen Jens Hjorth Dark Cosmology Centre (2005–2015) Niels Bohr Institute, U Copenhagen Primary goals  Carry out research that would otherwise not be possible (prior to DARK we were 2 permanent faculty)  Create a centre whose research and impact would live on beyond the 5 + 5 year funding model – legacy

Call for applications in 2003  We could relate to the key criteria: synergy, paradigm shift, cross-disciplinary, young  Turn existing visions into reality  Science  Setup  Grab new opportunities  Enable research in real fundamental and difficult stuff, address the biggest questions  3 Nobel Prizes in the field over the past decade  Make a difference  Spirit of change  Born international  Endeavour  Fun  Family feeling  Legacy  Openness  Creativity  Competitiveness  Diversity

Aim is to recruit the very best scientists

~200 applications each winter for DARK and Brahe Fellowships  Recognized PhD programme  5+3, 4+4, 3+5  17+13 = 30 students, 17 female, 19 international  6-month evaluation  Presentation to the Centre – what I have been doing and what I do propose to do; questions from audience  Essay – my strengths, weaknesses (science + soft skills)  Supervisor/student meets with committee  Committees  3 DARK scientists (including one post doc) + Coordinator  1 international member  Supervise the supervisor  Give input on plans, projects  Make demands, requirements  Present ideas, solutions, support  Internationalization  Gender balance  Teaching  Professional management and support  IT  External funding  Visitors  Recruitment  Societal engagement  410 papers in refereed international journals  14 papers in Science + Nature  External funding roughly matches DNRF funding, including: 1 ERC starting grant, 1 Lundbeck young group leader, 6 Marie Curie Fellows  7 former postdocs in permanent (academic) positions  NBI faculty: were 2 (males), are 5+1 (50-50 % gender balance), will be 8 by 2015  1 spin-off center  Nobel Prize 2011  1 DARK Associate Scientist  1 Collaborator  Euclid satellite selected for launch 2019  Many intermediate results  Stay tuned: Have two postdocs who might have the key  Hired because they were great, not because they were working on dark energy  Comes out of interaction and work on other problems  One we were able to attract because our admin staff could help one spouse settle in Denmark, has her own clinic now  Free research!!!  Scientific results!  Created a widely known centre with a long-term viability  DARK international family  A model for inspiration on how to do things (or how not to do things)  A fair gender balance in a hard-core field of research  Training of a new generation  World-wide network  A safe haven for busy researchers and a place for free spirits addressing deep questions
