Measurement of Quantum Fluctuations in Geometry
Craig J. Hogan
A particular form for the quantum indeterminacy of relative spacetime position of events is derived from the limits of measurement possible with Planck wavelength radiation. The in…
Quantum Indeterminacy of Emergent Spacetime
Craig J. Hogan
It is shown that nearly-flat 3+1D spacetime emerging from a dual quantum field theory in 2+1D displays quantum fluctuations from classical Euclidean geometry on macroscopic scales.…
The Sloan Digital Sky Survey-II Supernova Survey: Search Algorithm and Follow-up Observations
Masao Sako, B. Bassett, A. Becker +47
The Sloan Digital Sky Survey-II Supernova Survey has identified a large number of new transient sources in a 300 sq. deg. region along the celestial equator during its first two se…
A Study of the Type Ia/IIn Supernova 2005gj from X-ray to the Infrared: Paper I
J. L. Prieto, P. M. Garnavich, M. M. Phillips +53
We present extensive ugrizYHJK photometry and optical spectroscopy of SN 2005gj obtained by the SDSS-II and CSP Supernova Projects, which give excellent coverage during the first 1…
Spacetime Indeterminacy and Holographic Noise
Craig J. Hogan
A new kind of quantum indeterminacy of transverse position is shown to arise from quantum degrees of freedom of spacetime, based on the assumption that classical trajectories can b…
White Noise from Dark Matter: 21 cm Observations of Early Baryon Collapse
Kathryn M. Zurek, Craig J. Hogan
In concordance cosmology, dark matter density perturbations generated by inflation lead to nonlinear, virialized minihalos, into which baryons collapse at redshift . We…
