Two Postdoc Positions on Gravitational Waves Physics at IFAE

IFAE welcomes applications from outstanding candidates for two postdoctoral positions.

Position 1.

The successful candidate is expected to have:

• PhD Physics – internationally recognized experience on research using the LIGO-Virgo data.
• Experience developing pipelines and code for gravitational-wave searches and/or parameter estimation; knowledge of advanced Bayesian methods and samplers, machine learning approaches to signal processing; additionally other methods such as simulation-based inference.
• Good computing skills in python and good communication skills in English.

What will be your role?

The candidate will be expected to play a central role in the group’s activities in both data analysis and detector characterization. The candidate will implement new methods for compact binary searches and/or parameter estimation, including the use of machine learning/AI. This work will incorporate more realistic models of detector behavior and noise including glitches and non-stationarity in order to make robust detection of new physics. The candidate will also be expected to contribute to existing LVK data analysis and physics efforts (such as populations, PBH, testing GR, or others), including supervising students.

Applications should be submitted through Academic Jobs, including an up-to-date CV with full university records, a motivation letter, and two letters of reference.

Position 2.

The successful candidate is expected to have:

• PhD Physics – internationally recognized experience on research using the LIGO-Virgo data.
• Experience with optical simulation software used in gravitational-waves like Finesse, SIS, and others; knowledge of commercial codes like Zemax is a plus.
• Experience with electronics or hardware development, or commissioning of gravitational-wave detectors, is desirable.
• Good computing skills in python and good communication skills in English.

What will be your role?

The candidate will be expected to play a central role in the group’s detector-related activities including LIGO-Virgo detector characterization, optical simulation studies for stray light modeling in existing and future ground-based detectors, and the active monitoring of the stray light inside the optical cavities with new photo sensors in an ultra‑high vacuum environment. The candidate will also be expected to contribute to existing LVK data analysis and physics efforts, including supervising students.

Applications should be submitted through Academic Jobs, including an up-to-date CV with full university records, a motivation letter, and two letters of reference.

About IFAE

The Institut de Física d’Altes Energies (IFAE) is a public consortium of the Generalitat de Catalunya, the Autonomous Government of Catalonia, and the Universitat Autònoma de Barcelona (UAB, a public university) whose main objective is to carry out research and to contribute to the development of high energy physics from a theoretical, experimental and technological point of view. IFAE has the status of a “University Institute" attached to the UAB and its premises are within the campus of the University.

About the IFAE Gravitational Waves group

The detection of GWs from a black hole binary merger by LIGO in 2015 started a new era in the exploration of the universe. The addition of the Virgo antenna into the network led in 2017 to the detection of a neutron star binary merger that could be followed in electromagnetic signals, representing the beginning of multi‑messenger astronomy. At the moment, LIGO and Virgo observation plans extend until 2030 with upgraded detectors. At the same time, work is beginning on the development of the third generation of detectors which will offer an order of magnitude increase in sensitivity.

The ET project, a third‑generation experiment to be realized in Europe, has been included in the 2021 EU ESFRI roadmap and has recently entered into the preparatory phase. CE is the planned US contribution to the third‑generation GW network, with significant funding from the US NSF and the UK’s STFC for design studies.

IFAE is a member institution of the LVK collaboration. A group of researchers from IFAE has taken significant responsibilities in the Virgo experiment related to the control of the stray light inside the experiment, which is considered a limiting factor for its sensitivity. The group plays an important role in the commissioning, operations and upgrade of the interferometer. For the latter, IFAE is leading the construction of new baffles instrumented with photo sensors around the test masses.

IFAE is actively participating in ET, coordinates the EU Horizon INFRA‑DEV project for the ET preparatory phase, and has central responsibilities in the design of the stray light control systems. In addition, IFAE is deeply involved in the detector R&D and optical simulation activities of ET and CE. IFAE works with CERN in the design of the ET vacuum pipes.

The IFAE research program spans many topics in astrophysics and cosmology using LIGO‑Virgo data. This includes searches for compact binary coalescence events and determining their mass/spin spectrum, and for primordial black holes and axion‑like particles as candidates for dark matter. We perform tests of exotic models for Gravity beyond General Relativity, and cosmological measurements using GWs such as Hubble constant and probes of inflation and phase transitions in the early universe. We are developing new data analysis methods like the use of deep learning and the use of robust statistics. This work is naturally extended to studying physics prospects for the next generation of detectors.

IFAE is supported by its own PIC computing center, a Tier1 LHC center fully integrated into the LIGO/Virgo distributed computing network. IFAE is in a privileged position to analyze the LIGO/Virgo/KAGRA data and, in collaboration with IFAE’s teams in CTA/MAGIC and Observational Cosmology, to fully profit from a multi‑messenger approach.
