Mocking the Universe

In the coming era of LSST, PanSTARRS, WFIRST, Euclid, ALMA, ELTs, JWST, and other facilities, we want to know: What science can we learn by injecting more astrophysics into mock catalogs, and how can we use mock data to maximize the science output of real data?

9th International Conference on Interconnections between Particle Physics and Cosmology

Recent advances in observational astronomy and the discovery of 125-GeV Higgs boson have brought paradigm shifts on the potential connections between new fundamental particles and our understanding of their impact on the early universe and its evolution. With the content of the universe well known from astrophysical observations, a key aspect is that 27% of the universe appears to consist of dark matter. If current theories are correct, the particle physics candidate for this matter may well be observed in ongoing direct and/or indirect dark matter detection experiments or at the LHC. In addition, about 69% of the universe, the dark energy, still remains a significant mystery that major theoretical attempts are trying to understand.

Observational anomalies challenging the Lambda-CDM cosmological model

In the current paradigm of the Lambda-CDM cosmology, the fundamental properties of the Universe are believed to be well understood, with only minor adjustment of the basic model being left to be done. The global picture of an expanding Universe originating during a singularity at Big Bang is now taken for granted, and some basic properties of the Universe are considered to be known with amazing accuracy. For instance, according to Lambda-CDM concordance cosmology, the age of the Universe is 13.798±0.037 Gyr, quoted with a precision higher than the one with which we know the age of our planet.

Cosmology and the Epoch of Reionization

During the past decades, significant efforts have been made to investigate the physics in the late time Universe and during the Epoch of Reionization. Theoretical studies, advanced numerical models and observations have led to great insights into the astrophysics as well as the Cosmology present from redshift zero all the way up to redshifts of order 15. However, they also generated a plethora of interesting but thus far unanswered questions. Continua a leggere Cosmology and the Epoch of Reionization

Cosmology and Structure Formation

Our understanding of the cosmos has been making rapid progress thanks to an interplay of recent precision cosmological observations of the CMB and LSS, and advancement in theoretical understanding. The aim of this 6th KIAS workshop is to review the recent progress in the observational results and our current state of understanding of them from a theoretical perspective, in particular, within the framework of the standard Lambda CDM model and inflation.

Fundamental Issues of the Standard Cosmological Model

The Planck Satellite measurement have increased the accuracy of cosmological observations to a level which allows to constrain cosmological models with unprecedented precision. The aim of this workshop is to discuss the implications of these recent results combined with other (i.e. Planck, but also WMAP, galaxy surveys, SNIa data…) on models that aim at describing the primordial epochs and the origin and formation of large scale structures of the Universe.

Evolving Galaxies in Evolving Environments

The programme of the conference will cover the following topics:

  • Evolving environments: clusters, groups, density field, clustering, dark matter environment, and how they depend globally on redshift)
  • Central galaxies: links between accretion, bulge growth, star formation & AGN feedback, including BCGs.
  • Multiphase gas and environment: observations and simulations of gas budget vs halo mass, hot gas (detection, cooling, stripping), warm gas (absorption studies, abundance), cold gas (detection of flows, abundance).
  • Satellite galaxies: direct evidence of interaction with environment, physical mechanisms, simulations, empirical trends.
  • Tight interactions and no interactions: merging, close pairs, compact groups, fossils/isolated galaxies, etc.

Alpine Cosmology Workshop 2014

The concept of the workshop is to combine a scientific part, in which each participant delivers a review on their topic with a group activity in which every participant is engaged. To this end we have selected to conduct the workshop at several huts located in the Alps, connected by hiking trails. Each day has approximately 6 hours of the workshop and 6 hours of hiking, during which the participants usually continue the discussion of the scientific topics and establish new collaborations. The no escape principle, and no contact to outside, possible during the workshop, are unique attributes of the conference and allow participants to concentrate entirely on the subject of the conference, which includes:

  • Theoretical and observational cosmology
  • Physics of galaxy clusters
  • Coevolution of galaxies and black holes
  • Environmental effects in galaxy formation

Science Results from Pan-STARRS1

The Pan-STARRS1 Science Consortium has carried out a multi-color survey of the entire sky north of declination -30 degrees for more than 3 years using the Pan-STARRS1 telescope in Hawaii. The observing mission formally ends in March 2014 and the project is planning to release the data publicly in 2015 through the STScI archive. This meeting will present the breadth of science from Pan-STARRS1, ranging from solar system objects, low-mass stars, galaxy structure, and the transient sky, to the most distant quasars. Presentations from the PS1SC will review the status of the project along with descriptions of the data products and data quality and plans for public release. The meeting will review the results so far and describe future public data access and science exploitation of this immense legacy archive.
