Introduction

Cosmology has benefited greatly from the rapid development of experiments over the last decades. The goal of this Nordita program is to discuss current status and future perspectives in theoretical cosmology in light of currently available and expected data. What have we learnt from current data? What fundamental questions in physics can be probed with cosmology? How can advances in theoretical cosmology inform the choices made for new observatories and new observational directions? Given current technology, which of these questions can we address right now?

To address these questions, the community requires a detailed understanding of the interplay between independent datasets while maintaining a clear dialogue between theorists and observers. This is most easily achieved by bringing together experts from various sub-fields in cosmology to share ideas and discuss. Some of the key topics that will be covered at this meeting include: the nature of dark matter and dark energy; large-sky surveys, multi-frequency observations, and the complementarity of disjoint experiments; the interplay between cosmology and particle physics—both the Standard Model of Particle Physics and Beyond the Standard Model Research; recent advances in both hardware and software development in light of cosmological aspirations.

Although during each week particular emphasis is devoted to specific topics, the aim of the program is to highlight the common thread which links together various sub-fields in cosmology — theoretical advances in light of increasingly better-quality data — and boost cooperation and overlap between different areas. We thus encourage program participants to stay for a period of at least two weeks.

TimeActivityTopic
Week 1: Jul 3–7 Program Messengers: Astroparticles and Gravitational Waves
After the recent detection of a gravitational waves signal, the case for a multi-messenger approach to cosmology, combining information coming from different astrophysical observables, has become even stronger. This week will be devoted to discussing different probes of the universe and their complementarity: cosmic neutrinos, cosmic rays and gravitational waves. What is the state of the art of multi-messenger cosmology? What are the observational and theoretical challenges for the next future? Can we imagine novel approaches to multi-messenger astronomy to promote advances in theoretical cosmology? These are just some of the questions that we might want to discuss during this first week.
Week 2: Jul 10–14 Program The Dark Side: Dark Matter, Dark Energy, Dark Ages
Over the last couple of decades, we have established that the Universe has significant dark components and has experienced periods of dark time, when first stars haven't formed yet. During this week, we specializes in cross talks among theorists and observers/experimentalists in understanding the dark components of the Universe: Dark Matter and Dark Energy (or a modified version of gravity), while attempting to look at our linear Universe during Dark Ages. With the advent of many current and upcoming observations from Cosmic Microwave Background, 21cm, intensity mapping and large sky surveys, it would be pertinent to examine and discuss the theoretical ideas and possibilities in the light of the current and future observations.
Week 3: Jul 17–21 Conference Inflation and the CMB
The search for primordial gravitational wave signal is ongoing and the field is expected to advance significantly by the middle of 2017. The dedicated conference will give attendees the chance to discuss contemporary results in a forum that includes representatives from both theory and experiment. Young researchers will benefit from exposure to world-renowned cosmologists while the exchange of opinion will strengthen the basis for competitive inflation and CMB research in the Nordic countries.
Week 4: Jul 24–28 Program The low redshift universe
The low redshift universe ranges from the variable stars within our milky way, pulsars to extragalactic non-linear large scale structure. The wealth of the low redshift universe cannot be underestimated, ranging from forming the distance ladder to extra-galactic distances, pulsar timing for long period gravitational waves, the measurement of extra-galactic distances via Baryon Acoustic Oscillations and the evolution and formation of galaxies, blackholes throughout the history of the non-linear Universe. We will explore the fundamental constraints and theoretical possibilities of the Universe from these low redshift measurements in the final week of the conference.

Format

During the program (weeks 1, 2, and 4), there will be typically one or two talks per day, leaving ample time for interaction and collaboration. At the start of each week a pedagogical introductory lecture is planned on one of the central topics.

Conference: Inflation and the Cosmic Microwave Background, 17-21 July 2017.

Full one week conference on Inflation and the CMB. This conference will bring together experts from multiple sub-fields, including: early universe models; observational CMB; and cosmological data analysis; as well as general experts in cosmology. This conference is intended to provide the state-of-the-art as well as future directions in the field of inflation physics. Although CMB is considered the main observable, crucial results from complementary probes will be also discussed. Topics include: Current constraints on the constituents of the inflationary paradigm. Alternative early universe models. Projecting fundamental limits on the tensor to scalar ratio from Galactic foregrounds. Validity of the inflationary consistency relation. Parity violation. The future of CMB polarimetry.

Conference reception: Monday July 17 @ 19:00 in the AlbaNova main hall

Conference dinner: Wednesday July 19 @ 19:00, location to be decided

Application

If you want to apply for participation in the program, please fill in the application form. You will be informed by the organizers shortly after the application deadline whether your application has been approved. Due to space restrictions, the total number of participants is strictly limited. (Invited speakers are of course automatically approved, but need to register anyway.)

Application deadline: 31 March 2017

A minimum stay of one working week is required and we encourage program participants to stay for a period of at least two weeks.

There is no registration fee.

Travel Reimbursement

PhD students and young Postdoc fellows are eligible for travel grants to participate in the program. If you are interested in such a grant, please provide a statement to that effect in your application. Briefly summarize your interest in the program in the comments field, and indicate an estimation of your expected travel expenses. Since only a limited number of grants is available, decision concerning the grants will be made on a case-by-case basis and you will be notified shortly after the application deadline.

Daycare service

A daycare service can also be provided upon request. However, note that capacity is limited and provided on a first-come first-served basis.

Accommodation

Nordita provides a limited number of rooms in the Stockholm apartment hotel BizApartments free of charge for accepted participants.
