Description:

Current and future cosmology missions in the big data era of astronomy can greatly benefit from advances in deep learning. Architectures based on convolutional neural networks (e.g., GANs, deep image prior, diffusion probabilistic models) are well tested for applications such as image generation, data/image to image translation, feature/domain transfer, or super resolution. These applications could notably enhance astronomical measurements from combined data sets.  For instance, images boosted in depth and/or resolution can be used to increase the number of usable sources for weak lensing, reduce the systematics errors due to blending, photometric redshifts, and shape measurements, and potentially put tighter constraints on the cosmological parameters measurable through weak lensing. Data from the current ground- and space-based surveys (with e.g., HSC, KiDS+Viking, DES, HST) will be used to quantify the gain for the upcoming missions (i.e., Rubin, Euclid, Roman, and SPherex) with heavy JPL, Caltech and IPAC contributions. We are seeking a postdoctoral fellow to lead this effort. Experience with deep learning frameworks is highly desirable, and familiarity with multi-band spectro/photometric galaxy data of existing and future cosmology missions as well as a broad knowledge of weak lensing systematics is preferred. The successful candidate will be working closely with Dr. Eric Huff and Dr. Shoubaneh Hemmati and other members of the cosmology team at JPL.
