N2 - ATLAS (Astrophysics Telescope for Large Area Spectroscopy) Probe is a
concept for a NASA probe-class space mission that leverages WFIRST
imaging for targeted spectroscopy. ATLAS Probe will obtain spectra of
90% of all galaxies imaged by the WFIRST High Latitude Survey at z >
0.5, with slit spectra of 300 million galaxies to z = 7. ATLAS Probe and
WFIRST together will produce a 3D map of the Universe with Mpc
resolution over 2200 sq deg, the definitive data sets for studying
galaxy evolution, probing dark matter, dark energy and modification of
general relativity, and quantifying the 3D structure and stellar content
of the Milky Way.ATLAS Probe science spans four broad categories: (1)
Revolutionize galaxy evolution studies by tracing the relation between
galaxies and dark matter from the local group to cosmic voids and
filaments, from the epoch of reionization through the peak era of galaxy
assembly. (2) Open a new window into the Universe by mapping the dark
matter filaments using 3D weak lensing with spectroscopic redshifts to
unveil the nature of the dark Universe, and obtaining definitive
measurements of dark energy and possible modification of general
relativity using cosmic large-scale structure. (3) Probe the Milky Way's
dust-shrouded regions, reaching the far side of our Galaxy. (4)
Characterize asteroids and comets in the outer Solar System.ATLAS Probe
is a 1.5m telescope with a field of view (FoV) of 0.4 sq deg, and uses
Digital Micromirror Devices (DMDs) as slit selectors. It has a
spectroscopic resolution of R = 600, and a wavelength range of 1-4μm.
The lack of slit spectroscopy from space over a wide FoV is the obvious
gap in current and planned future space missions; ATLAS fills this big
gap with an unprecedented spectroscopic capability (with an estimated
spectroscopic multiplex factor of 5000-10000). It has an estimated cost
under $1B, with a single instrument, a telescope aperture that allows
for a lighter launch vehicle, and mature technology (DMDs can reach
Technology Readiness Level 6 within two years). ATLAS Probe will lead to
transformative science over the entire range of astrophysics: from
galaxy evolution to the dark Universe, from Solar System objects to the
dusty regions of the Galaxy.
