3D-DASH

The Widest Near-Infrared Hubble Space Telescope Survey

The 3D-DASH F160W Mosaic

The 3D-Drift And SHift (3D-DASH) program is a Hubble Space Telescope WFC3 F160W imaging and G141 grism survey of the equatorial COSMOS field. 3D-DASH is the widest HST/WFC3 imaging survey in the F160W filter to date, subsuming the COSMOS-DASH pilot survey (Mowla et al. 2019b). 3D-DASH extends the legacy of HST near-infrared imaging and spectroscopy to degree-scale swaths of the sky, enabling the identification and study of distant galaxies (z > 2) that are rare or in short-lived phases of galaxy evolution at rest-frame optical wavelengths.

All our data products are available on our MAST page.

You can now explore the entire mosaic in all available filters using the FitsMap (credit: Gabe Brammer).

Cutout and psf

You can generate point spread functions or create cutouts at any location within the 3D-DASH footprint in this notebook.
