Postdoctoral Research Scholar in 21cm Cosmic Dawn
School of Earth and Space Exploration (SESE)
Arizona State University
Read full job posting.
We invite applications for a postdoctoral research scholar in redshifted 21cm observations of Cosmic Dawn. The successful candidate will work with Professors Danny Jacobs and Judd Bowman on self-directed projects with redshifted 21cm telescopes, including HERA, MWA, EDGES, and/or OVRO-LWA. HERA is currently operating and has begun regular data releases. OVRO-LWA and MWA are completing upgrades which will significantly improve systematic floors. Opportunities are available to analyze 21cm power spectra, including to fit models for galaxy evolution and fundamental physics to observations, identify and remove foregrounds from observations, develop simulations and tests to validate pipelines, and forecast results for current and upgraded instruments, among other investigations. Additional potential topics include development of advanced instrument concepts and hardware solutions to address systematic limits in 21cm observations. The successful candidate will work in close collaboration with partner institutions in these projects and have numerous opportunities for travel to team meetings and conferences. The position is a full-time, fiscal year appointment with benefits and relocation allowance. It will be renewed annually for up to a total of three years, contingent upon satisfactory performance, the needs of the university, and availability of resources.
To apply, please submit to http://apply.interfolio.com/100036 to include the following: 1) a cover letter, 2) a research statement not longer than five pages including figures and references; 3) a statement addressing how your past and/or potential contributions to diversity and inclusion will advance ASU's commitment to inclusive excellence, 4) a current CV; and 5) the names and contact details of three references.
Postdoctoral Research Scholar in Observational Astrophysics and Computational Science
School of Earth and Space Exploration (SESE)
Arizona State University
The radio astronomy group at ASU invites applications for a postdoctoral research scholar to conduct research on efficient, scalable signal processing for large interferometer arrays and fast transient detection. The position includes an annual stipend of $63,000, full-time, fiscal year, with benefits. A relocation allowance will be provided.
A pathfinder of a novel aperture-plane FFT correlator, called EPIC, is currently deployed on the Long Wavelength Array (LWA) station in Sevilleta, New Mexico. The system uses the GPU-accelerated Bifrost framework (C++/CUDA/Python) and images the entire visible sky every 40 microseconds. The successful applicant will upgrade the pathfinder to an operational system by optimizing the algorithm and implementation and deploying a real-time transient detection backend. They will assist with the installation and commissioning of new hardware nodes at the LWA stations in New Mexico and at the Owens Valley Radio Observatory LWA station in California. The operational system will provide unique opportunities for the study of fast radio burst (FRB) progenitors through low-frequency searches, as well as through simultaneous and follow-up observations of detections by other telescopes, including CHIME, DSA, and Realfast. The system will provide additional opportunities for astronomical and atmospheric research.
Essential duties of the position: The successful applicant will develop software, plan and analyze astronomical observations, conduct original research, document results, write journal articles, and present at scientific meetings.
Minimum Qualifications: (1) Ph.D. in a relevant field by the time of appointment, but no earlier than five years before the start date, (2) demonstrated record of research accomplishment in a related field.
Desired Qualifications: (1) Relevant experience in radio instrumentation and observations, signal processing, statistical data analysis, and/or software development, (2) a record of prior achievement and experience that shows the applicant’s potential to accomplish research and/or development objectives, (3) evidence of strong verbal and written communication skills, (4) evidence of ability to work well independently and in team settings.
Established in 2006, SESE is the focal point of astrophysics at Arizona State University, one of the most dynamic and fastest growing institutions of higher learning in the United States. An essential part of SESE's mission is to make new discoveries by promoting interdisciplinary science and by integrating science and engineering. SESE faculty and their research groups benefit from a variety of state-of-the-art facilities including high performance computing, access to the 2x8.4m Large Binocular Telescope, 6.5m MMT telescope, 6.5m Magellan telescopes and a host of 2m-class telescopes owned and operated by the State of Arizona. ASU is a founding member in the Giant Magellan Telescope and a partner in the Hydrogen Epoch of Reionization Array (HERA), the Long Wavelength Array Swarm, and the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA). ASU is participating in the CMB-S4 consortium and is a member of the Simons Observatory (SO), the Toltec project, and several astrophysics sub-orbital class programs.
