[26.01] ALLEGRO: ALl sky Low Energy Gamma Ray Observatory

M. Ulmer (Northwestern University), D. Dixon (UC Riverside), G. Pendleton (UAH), W. Wheaton (IPAC/CIT), S. Matz (Northwestern University), J. Finley (Purdue University), W. Purcell, R. Nyquist, J. Jonaitis (Ball)

We present a novel concept for a Midex that allows all sky coverage for gamma-ray burst and hard X-ray transients. The novel Multiscale Alternating Shadow Collimator (MASC) alone allows for arc minute positioning of 1 second bursts. Our scientific objectives include: (a) The ability to detect and monitor thousands of GRBs and hard X-ray sources with sensitivity 3-10 times better than BATSE ; (b) to solve the gamma-ray burst mystery, to use gamma-ray bursts as probes of star formation and to measure cosmological parameters; (c) to understand the physics of the high energy radiation from AGNs and BLAZARs;(d) to study the physics of matter in the extreme around black holes and neutron stars; (e) to determine the pulsar birth rate characteristics. The mission concept, MASC concept and simulations will be presented.
