A Decoupled Human-in-the-Loop System for Controlled Autonomy in Agentic Workflows
Edward Cheng, Jeshua Cheng
AI agents are increasingly deployed to execute tasks and make decisions within agentic workflows, introducing new requirements for safe and controlled autonomy. Prior work has esta…
Joint Efficient Dark-energy Investigation (JEDI): a Candidate Implementation of the NASA-DOE Joint Dark Energy Mission (JDEM)
Arlin Crotts, Peter Garnavich, William Priedhorsky +15
JEDI will probe dark energy in three independent ways by measuring the expansion history of the universe: (1) using type Ia supernovae as cosmological standard candles over a range…
Strong gravitational lensing probes of the particle nature of dark matter
Leonidas A. Moustakas, Kevork Abazajian, Andrew Benson +44
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these ca…
The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA)
Leonidas A Moustakas, Adam J Bolton, Jeffrey T Booth +15
(abridged) The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA) is a mission concept for a 1.5-m near-UV through near-IR space observatory that will be dedicated…
The Amplitude and Spectral Index of the Large Angular Scale Anisotropy in the Cosmic Microwave Background Radiation
Ken Ganga, Lyman Page, Edward Cheng +1
In many cosmological models, the large angular scale anisotropy in the cosmic microwave background is parameterized by a spectral index, , and a quadrupolar amplitude, . For…
Bending and Breathing Modes of the Galactic Disk
Lawrence M. Widrow, Jarrett Barber, Matthew H. Chequers +1
We explore the hypothesis that a passing satellite or dark matter subhalo has excited coherent oscillations of the Milky Way's stellar disk in the direction perpendicular to the Ga…
The Joint Efficient Dark-energy Investigation (JEDI): Measuring the cosmic expansion history from type Ia supernovae
M. M. Phillips, Peter Garnavich, Yun Wang +6
JEDI (Joint Efficient Dark-energy Investigation) is a candidate implementation of the NASA-DOE Joint Dark Energy Mission (JDEM). JEDI will probe dark energy in three independent me…
