Tucson, Arizona, United States NSF's NOIRLab Full time
About NSF's NOIRLab

NSF's NOIRLab is a leading national center for ground-based, nighttime optical and infrared astronomy. The organization's mission is to drive breakthrough discoveries in astrophysics by developing and operating state-of-the-art observatories and providing data products and services for a diverse community.

The team operates as a matrix organization, delivering services across various programs: Gemini, Rubin, MSO (CTIO and KPNO), and CSDC; with approximately 400 employees at facilities in three geographic locations: Arizona, Hawai'i, and Chile.

Job Summary

We are seeking a Postdoctoral Research Associate to use high-precision photometry and astrometry catalogs obtained from HST/ACS, HST/WFC3, and JWST/NIRCam to reconstruct the internal kinematics of the young massive cluster 30 Doradus in the Large Magellanic Cloud.

The successful candidate will use Bayesian inference to characterize the ages and physical properties of stars in 30Doradus. They will compare proper motions displacements and ages of stars with models of cluster formation and early evolution to determine 30 Doradus assembly history and evolution.

Responsibilities include processing MIRI observations to identify and characterize young stellar objects present in the region to establish sites of most recent star formation in the complex.

Essential Functions
  • Align and process MIRI observations to HST and JWST/NIRCam catalogs provided by CoIs at STScI
  • Perform photometry analysis of MIRI observations
  • Combine MIRI photometry catalog with available HST and JWST/NIRcam one.
  • Use Bayesian inference to fit spectral energy distribution of stars and young stellar objects to determine their ages and physical properties.
  • Use proper motion displacements and ages to reconstruct internal kinematics of 30 Doradus
  • Compare results with models of cluster formation and evolution.
Additional Responsibilities
  • Other duties as assigned
Required Skills and Qualifications
  • PhD in astronomy
  • Programming experience with Python
  • Experience in Bayesian inference and SED fitting
  • Experience in studies of stellar evolution, YSO, or star cluster internal dynamics
  • Prior experience with JWST/MIRI data is highly desirable
  • Self-motivate, independent, and highly organized
Benefits

AURA offers an excellent benefits package including paid time off and retirement plan contributions, competitive salary commensurate with experience, and a very attractive work environment. The estimated salary range for this position is $65,000 - $72,000 per year, depending on skills, qualifications, and experience.
