Postdoctoral Fellow in Dark Energy and the Origin of the Universe

Application deadline:

The Institute of Cosmos Sciences of the University of Barcelona (ICCUB) is seeking a Postdoctoral Fellow in Dark Energy and the Origin of the Universe for its Unit of Excellence Maria de Maeztu postdoctoral positions. Find out more positions in related areas here.

The ICCUB is an interdisciplinary center with more than 60 long term scientists, 20 engineers and 80 postdoctoral researchers (55% international) and PhD students (30%international) offering an international and multicultural environment. The ICCUB also hosts a vibrant fundamental research program in cosmology, astrophysics and particle physics, with a strong technology unit supporting our participation in international collaborations in observational astronomy and experimental particle physics.

Job description
We are looking for enthusiastic researchers who share our curiosity to understand the physics of the Universe from the infinitely small to the infinitely large and the deep connections between these different scales.

You will have the opportunity to work on large-scale structure cosmology, (both theoretical and observational), dark energy and Early Universe.

Forthcoming surveys with exquisite statistical power promise advances on big open questions with deep links to fundamental physics: the nature of dark energy and dark matter, neutrino masses, the early Universe physics driving inflation, etc.

The rapidly growing amount of data in cosmological surveys demands a strong analysis effort to extract important scientific discoveries; a close interaction between theory and observations is crucial for formulating the most relevant questions and developing precise data analysis techniques to find the correct answers.

We anticipate that this process will be strongly influenced by the nascent field of multi-messenger cosmology: gravitational waves with electromagnetic counterparts (e.g, providing redshift measurements). As an example of promising synergies, this combination will result in independent distance measurements, and cross-correlating gravitational wave sources with galaxy maps can trace the origin of black hole mergers (see line B here).

You will be joining a broad group of researchers with interests in Cosmology, -- see (under GROUP) and -- which comprises 5 faculty, 4 postdocs, and 8 graduate students.

Experience with cosmology, analysis of data, statistics, possibly applied in the cosmological context and being proficient with coding is highly desirable. Familiarity with inflation, general relativity and field theory would be valued. Familiarity with high performance computing is a welcome plus.

Members of this group are involved in the following surveys/collaborations: DESI, EUCLID.

The priority lines of the Maria de Maeztu proposal canbe found here.
