The Lomb-Scargle periodogram is a well-known algorithm for detecting and characterizing periodic signals in unevenly-sampled data… Expand We present rotation periods for thousands of active stars in the Kepler field derived from Q3 data. In most cases a second period… Expand We explore the newly discovered "hangup-kick" effect, which greatly amplifies the recoil for configuration with partial spin… Expand We begin by revisiting the periodogram to explain why arguably the plain least-squares periodogram (LSP) is preferable to the… Expand We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey… Expand We investigate the connection between globular clusters and ultracompact dwarf galaxies (UCDs) by examining the properties of 10… Expand The advent of long-term studies on CO2 and water vapor exchange provides us with new information on how the atmosphere and… Expand We present an analysis of 11 yr of precision radial velocity measurements of 76 nearby solar-type stars from the Lick radial… Expand In this paper, we give a brief review of the theory of spectral analysis of large dimensional random matrices. Most of the… Expand The statistical properties of least-squares frequency analysis of unequally spaced data are examined. It is shown that, in the… Expand
