Postdoc in Experimental Cosmology at Caltech, Sep 1, 2021

The Caltech experimental cosmology group seeks a Postdoctoral Scholar to advance CMB observations and technology for BICEP Array and CMB-S4. The BICEP-Keck program is producing deep CMB polarization measurements and placing field-leading constraints on Inflationary B-mode polarization. The newest BICEP Array stage of the program is funded and currently in implementation. When fully fielded, BICEP Array will operate over 30,000 detectors in 6 frequency bands, deploying and observing over the next 5 years from the South Pole. The project has begun joint observations and analysis with the 10m South Pole Telescope to improve measurements of gravitational lensing that are essential for stronger constraints on Inflationary physics. Candidates will play a leading role in designing, testing, fielding, and analyzing data from the new BICEP Array receivers. The highest frequency receiver will demonstrate new TKID technology being developed at Caltech/JPL for large, highly-multiplexed CMB arrays. Candidates may choose to join local efforts towards the CMB-S4 project, including developing new detector arrays. The successful applicant will have access to data accumulated to date from the BICEP-Keck program, as well as access to collaborative programs with the South Pole telescope covering a wide range of scientific topics. .

Fellowship at NSF AI Institute for Artificial Intelligence and Fundamental Interactions, Sep 21, 2021

The NSF AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI) is one of the inaugural NSF AI research institutes. The IAIFI will enable physics discoveries and advance foundational AI through the development of novel AI approaches that incorporate first principles from fundamental physics. AI is transforming many aspects of society, including the ways that scientists are pursuing groundbreaking discoveries. For many years, physicists have been at the forefront of applying AI methods to investigate fundamental questions about the Universe. Further progress will require a revolutionary leap in AI, as both the complexity of physics problems and the size of physics datasets continue to grow.

The goal of the IAIFI is to develop and deploy the next generation of AI technologies, based on the transformative idea that artificial intelligence can directly incorporate physics intelligence. IAIFI researchers will use these new AI technologies to tackle some of the most challenging problems in physics, from precision calculations of the structure of matter, to gravitational wave detection of merging black holes, to the extraction of new physical laws from noisy data. IAIFI researchers will also transfer these technologies to the broader AI community, since trustworthy AI is as important for physics discovery as it is for other applications of AI in society. To cultivate human intelligence, the IAIFI will promote training, education, and outreach at the intersection of physics and AI. In this way, the IAIFI will advance physics knowledge – from the smallest building blocks of nature to the largest structures in the Universe – and galvanize AI research innovation.

Staff Physicists at Argonne National Laboratory, Oct 31, 2021

The Cosmological Physics and Advanced Computing (CPAC) Group in the High Energy Physics (HEP) division at Argonne National Laboratory is seeking a highly qualified candidate in the area of cosmic microwave background (CMB) instrumentation and data analysis to contribute to current projects including SPT-3G and CMB-S4, as well as to develop future opportunities.

The successful candidate must have a PhD in physics or related fields and appropriate postdoctoral experience. Areas of technical expertise include cryogenic receiver design and operation, superconducting detector and readout system design and implementation, CMB receiver integration and commissioning, and CMB data analysis ranging from low-level processing, instrumental systematics verification to cosmological constraints. Experience with high performance computing and AI/ML expertise would be helpful. A demonstrated record of student and/or postdoctoral mentorship and proposal writing, along with strong oral and written communication skills, is highly desirable. The selected candidate will work in a highly collaborative environment within CPAC, HEP division, and Argonne National Laboratory, and with academia and other national laboratories.  CPAC hosts wide-ranging programs in theory, modeling, and simulation and in experiment and observation focusing on optical and CMB surveys, including CMB-S4, DES, DESI, Rubin Observatory’s LSST, SPHEREx, and SPT-3G.

Postdoc at Michigan State University, July 20, 2021

Michigan State University invites applications for a postdoctoral position on the South Pole Telescope (SPT) Experiment, with additional work on the forthcoming CMB-S4 project. The recently-deployed (2018) SPT-3G receiver will provide maps of Cosmic Microwave Background intensity and polarization with unprecedented sensitivity at small angular scales, enabling a wide variety of science, in particular the measurement of the properties of light relativistic particles such as neutrinos in the early universe. MSU plays a leading role in the SPT experiment in data analysis and participates in the project at all levels.

The successful applicant will work in the research group of Prof. Nathan Whitehorn. The position will include analysis of data from the SPT-3G receiver recently deployed to the telescope, as well as forecasting and pipeline development for the forthcoming CMB-S4 project.

Postdoc at University of Ferrara, Sep 30, 2021

The Cosmology group at the Department of Physics and Earth Science, University of Ferrara (UNIFE), Italy, invites expressions of interest for a fixed-term staff position* from outstanding candidates with a strong research record in cosmic microwave background (CMB) and large scale structure (LSS) data analysis and interpretation.
