PI: prof. dr hab. Agnieszka Pollo

Application deadline: 2025-06-09

Start Date: flexible

Location: Pasteura 7, 02-093 Warsaw

The post-doc position is offered as part of a project entitled "Barely visible: low surface brightness galaxies in the LSST era" and funded by a MAESTO grant from the National Science Centre led by the prof. Agnieszka Pollo (agnieszka.pollo@ncbj.gov.pl). The position is for a fixed term of two years, with the possibility of an extension for a further year depending on the candidate's performance (2+1). The successful candidate will join a team of scientists studying Low Surface Brightness Galaxies (LSBGs) within the Rubin Observatory Legacy Survey of Space and Time (LSST) collaboration with access to early data.

The project offers some flexibility depending on the candidate’s previous experience and scientific interests, but is expected to focus mainly on the topic related to the extragalactic astronomy, in particular the analysis of observations of low surface brightness galaxies. The main objective will be to study the relationships between LSBGs and the large-scale structure of the Universe, with the aim of understanding how the LSBGs are connected to the underlying dark matter field. Different approaches can be used: clustering analysis (correlation functions, cross-correlations, marked statistics), halo occupation distribution models, local density measurements or machine learning methods. The candidate may also choose to work on the theoretical interpretation of the results in the context of different cosmological and dark matter models. The results of this research will provide important insights into the nature of very faint galaxies and their role in galaxy formation and evolution scenarios.

The successful candidate will join an international team of scientists with expertise in LSBGs, galaxy morphology, SED fitting, machine learning, and galaxy clustering and will have a unique opportunity to acquire expertise in all these aspects. Additionally a rich travel budget will allow the PhD candidate to participate in international conferences and workshops, as well as short international research exchanges.

The Astrophysics Division (BP4) of the Fundamental Research Department of the National Centre for Nuclear Research (NCBJ) employs 19 people at the level of post-doc, assistant professor and professor (including 8 foreigners) and 13 PhD students (of various nationalities).
We carry out research in astrophysics and astronomy, in particular their observational aspects. Our main areas of interest are cosmology (including the microwave background radiation, large-scale structure of the Universe, dark matter and gravitational lensing), gravitational waves (multi-messenger astronomy), galaxy properties (formation and evolution of galaxies, active galactic nuclei, quasars) and the interstellar medium (star formation, neutron stars and white dwarfs).
