Optical Surveys for Galaxy Clusters
Optical surveys for galaxy clusters have been the major method for creating large cluster catalogs. We give a brief review of the history of optical searches of galaxy clusters, starting from that of Abell. The traditional application of this survey method suffers from contamination due to projection of galaxies along the line of sight, which becomes increasingly more severe at higher redshift....
متن کاملAn Integrated Optical Transient Sensor
The implementation of a compact continuous-time optical transient sensor with commercial CMOS technology is presented. In its basic version, this sensor consists of a photodiode, five transistors and a capacitor. The proposed circuit produces several output signals in parallel. These include a sustained, logarithmically compressed measure of the incoming irradiance, half-wave rectified and thre...
متن کاملTransient chaos in optical metamaterials.
We investigate the dynamics of light rays in two classes of optical metamaterial systems: (1) time-dependent system with a volcano-shaped, inhomogeneous and isotropic refractive-index distribution, subject to external electromagnetic perturbations and (2) time-independent system consisting of three overlapping or non-overlapping refractive-index distributions. Utilizing a mechanical-optical ana...
متن کاملReal-Time Classification of Transient Events in Synoptic Sky Surveys
An automated rapid classification of the transient events detected in modern synoptic sky surveys is essential for their scientific utility and effective follow-up when resources are scarce. This problem will grow by orders of magnitude with the next generation of surveys. We are exploring a variety of novel automated classification techniques, mostly Bayesian, to respond to those challenges, u...
متن کاملVolumetric Survey Speed: A Figure of Merit for Transient Surveys
Time-domain surveys can exchange sky coverage for revisit frequency, complicating the comparison of their relative capabilities. By using different revisit intervals, a specific camera may execute surveys optimized for discovery of different classes of transient objects. We propose a new figure of merit, the instantaneous volumetric survey speed, for evaluating transient surveys. This metric de...
