NRC fellowship at NIST
Deadline: Feb 1, 2020
There is an upcoming postdoctoral fellowship opportunity to work with the Quantum Sensors Group at NIST, Boulder. The National Research Council (NRC) fellowship application deadline is twice a year, on Feb 1 and August 1. This is a two-year, well-paid position open to US citizens that have completed their PhD within the past 5 years. Our group's research focus is the development of superconducting detectors, multiplexing technology, and applications at millimeter-wavelength with a particular emphasis on CMB polarization. Current projects include the Simons Observatory, LiteBIRD, AliCPT, CMB-S4, TolTec, CCAT-prime, SPIDER, Advanced ACTPol, and BLAST-TNG. Technology programs include the development of Transition-Edge-Sensor (TES) bolometers, Microwave Kinetic Inductance Detectors (MKIDs), quantum-limited microwave amplifiers, quantum-sensing approaches for high energy physics and beyond, microwave SQUID multiplexers, planar-metamaterial lenslet arrays, feedhorn arrays, and Normal-Insulator-Superconductor (NIS) refrigerators. Interested candidates are encouraged to speak with Johannes Hubmayr directly (hubmayr@nist.gov, 303.497.6164)Learn more

 
Post-doc in Cosmology at the University of Groningen
Deadline: Jan 15, 2020
The Van Swinderen Institute (VSI) of the Faculty of Science and Engineering has an opening for a Postdoc working in collaboration with Assistant Professor Daan Meerburg on aspects of analysis for upcoming cosmological datasets, as well as theoretical modeling, with a focus on the cosmic microwave background (CMB). Dr Meerburg is a newly appointed staff member (April 2019) working on topics in theoretical and observational cosmology. He is a senior member of the Simons Observatory (SO), and new ground based CMB experiment to be deployed in the Atacama desert with expected first light in Jan 2021.

Dr Meerburg is funded through a NWO Vidi grant (title: The Cosmic Laboratory). We are looking for someone who is working on different aspects of this proposal. In particular, you will take a leading role within the SO working group responsible for constraining primordial non-Gaussianities. In addition, you are encouraged to work on theoretical aspects of cosmology and collaborate with others at the VSI. The neighboring Kapteyn Institute hosts staff members directly involved in 21 cm cosmology and simulations of large scale structure. Candidates interested in collaborating with members of both institutions are encouraged to apply.Learn more

 
Faculty position in Particle Astrophysics, Cosmology and Gravitational Waves at UC Riverside
Deadline: Feb 15, 2020
The Department of Physics and Astronomy at the University of California, Riverside (https://www.physics.ucr.edu/) invites highly qualified experimental physicists to apply for an Academic-year tenure-track or tenured faculty position in the fields of Particle Astrophysics, Cosmology and Gravitational Waves. Four new experimental physics positions in these emerging areas of physics, including one at mid-level, are expected over the next few years.

Candidates should possess a record of demonstrated excellence in research. The successful candidate is expected to establish an outstanding and well-funded research program involving graduate students and postdoctoral scientists, and to contribute to departmental teaching at all levels. We are initiating a new experimental group at UC Riverside to augment and complement ongoing efforts in particle physics and astronomy. We are seeking independent researchers, who will build significant on-campus research efforts involving undergraduates, graduate students and postdocs on the forefront experimental programs in this general area of physics. We anticipate that individual hires may work together or on different experimental projects. We seek individuals with strong academic promise, who can build significant research efforts at UCR in forefront areas that will complement existing programs in our department.Learn more

 
Postdoctoral researcher in Cosmology at U. Geneva
Jan 15, 2020
We invite applications for a postdoctoral position in cosmology at the University of Geneva, starting in Fall 2020 or earlier. The successful candidate will primarily work with Dr. Julien Carron who will join the the Cosmology and Astroparticle physics group in 2020.

A completed, or near to completion, PhD in Physics, Cosmology, Astrophysics, Astronomy or similar area is required. The position is initially for two years, and funded by a SNSF grant associated to Dr. Carron with main focus Cosmic Microwave Background lensing data analysis for current and upcoming experiments. The Cosmology and Astroparticle physics group is also strongly involved in galaxy clustering, weak gravitational lensing, gravitational waves, dark energy, and modified gravity (see http://cosmology.unige.ch/) and broad collaboration is encouraged.Learn more and apply

 
Computer Systems Engineer at LBNL
Open until filled
Berkeley Lab’s Computational Research Division has an opening for a Computer Systems Engineer. This position will support the development and deployment of high performance computing frameworks, pipelines, and modules required for the synthesis and reduction of data from next-generation Cosmic Microwave Background experiments, with a particular focus on using the TOAST-based software stack for CMB-S4 at the National Energy Research Scientific Computing Center (NERSC).

What You Will Do:
Maintain an optimized installation of the TOAST software stack on current and pending NERSC systems and environments.
Manage the continuous integration of the TOAST software stack.
Benchmark standard pipelines and identifying performance bottlenecks.
Work with CMB-S4 users to help trouble-shoot software installation and performance issues.
Support the transition of the software stack to GPU-based systems such as NERSC’s Perlmutter.Learn more and apply

 
Postdoc on Ultra-sensitive Far-IR Bolometers at JPL
We are seeking a postdoctoral researcher to lead the demonstration of the world's most sensitive far-IR detectors. We are building transition-edge sensor (TES) arrays with per-pixel noise equivalent power of 10^-19 W/sqrt(Hz) in the JPL micro devices lab (MDL) in preparation for space-borne astrophysics missions including SPICA and the Origins Space Telescope. We are characterizing the prototype TES arrays electrically and optically in our dilution-cooled test facility using a frequency-domain multiplexing readout. The postdoc will work closely with our dynamic group of scientists, technologists and engineers in Pasadena, as well as our collaborators at SRON, Holland. Key people in the JPL detector group include Drs. Matt Kenyon, Pierre Echternach, and Roger O'Brient. For qualified and interested candidates, opportunities also exist for collaboration on ongoing and proposed ground-based and balloon-borne instruments targeting the early Universe. Experiments include SuperSpec (a millimeter-wave spectrometer on a chip slated for the large millimeter telescope targeting individual high-redshift galaxies ), TIME (a mm-wave tomographic intensity mapper targeting ionized carbon fro the Reionzation epoch), and TIM ((formerly STARFIRE), a proposed balloon-borne far-IR imaging spectrometer targeting the history of star formation when the Universe was half its current age). Dr. Matt Bradford will serve as the postdoctoral advisor. The appointee will carry out research in collaboration with the JPL advisor and others, resulting in publications in the open literature.Learn more

 
Postdoctoral researchers in experimental cosmology at Argonne
The High Energy Physics Division at Argonne National Laboratory invites applications for postdoctoral research positions in the Experimental Cosmology group. Members of our group study the cosmic microwave background as participants in the South Pole Telescope (SPT, https://pole.uchicago.edu/) and CMB-S4 (https://cmb-s4.org/) collaborations. Successful applicants will have opportunities for cosmological analysis of data from the SPT-3G receiver as well as in technology development for CMB-S4. They will have access to multiple test and fabrication facilities at Argonne, the latter involving close collaboration with the Materials Science Division and the Center for Nanoscale Materials. Opportunities also exist to collaborate closely with the Cosmological Physics and Advanced Computing group as well as groups at Fermilab and the University of Chicago.Learn more (Job ID #407093)
