Wide band, tunable gamma-ray lenses
Niels Lund
A new concept for an astronomical telescope in the MeV energy band is presented. The concept builds on Bragg diffraction in crystals, which has been discussed in the past, but so f…
Technologies for tunable gamma-ray lenses
Niels Lund
The tunable gamma-ray lens has turned out to be a promising alternative to the classical fixed-energy Laue-lenses discussed in the past. We describe here our development work on a…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
An Extreme Precision Radial Velocity Pipeline: First Radial Velocities from EXPRES
Ryan R. Petersburg, J. M. Joel Ong, Lily L. Zhao +13
The EXtreme PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, , optical spectrograph. It was recently commissioned at the 4.3-m Lowell Discove…
ATLAS Probe: Breakthrough Science of Galaxy Evolution, Cosmology, Milky Way, and the Solar System
Yun Wang, Massimo Robberto, Mark Dickinson +37
ATLAS (Astrophysics Telescope for Large Area Spectroscopy) Probe is a concept for a NASA probe-class space mission. It is the follow-up space mission to WFIRST, boosting its scient…
eXTP -- enhanced X-ray Timing and Polarimetry Mission
S. N. Zhang, M. Feroci, A. Santangelo +181
eXTP is a science mission designed to study the state of matter under extreme conditions of density, gravity and magnetism. Primary targets include isolated and binary neutron star…
