New data are reported from the operation of the PICO-60 dark matter detector, a bubble chamber filled with 36.8 kg of CF 3 I and located in the SNOLAB underground laboratory. PICO-60 is the largest bubble chamber to search for dark matter to date. With an analyzed exposure of 92.8 livedays, PICO-60 exhibits the same excellent background rejection observed(More)
Low Reynolds number aerodynamics is important for various applications including micro-aerial vehicles, sailplanes, leading edge control devices, high-altitude unmanned vehicles, wind turbines and propellers. These flows are generally characterized by the presence of laminar separation bubbles. These bubbles are generally unsteady and have a significant(More)
We present observations of the dwarf galaxies Draco andUrsaMinor, the Local Group galaxiesM32 andM33, and the globular cluster M15 conducted with the Whipple 10 m gamma-ray telescope to search for the gamma-ray signature of self-annihilating weakly interacting massive particles (WIMPs), which may constitute astrophysical dark matter (DM). We review the(More)
We report results from an intensive multi-wavelength monitoring campaign on the TeV blazar Mrk 421 over the period of 2003–2004. The source was observed simultaneously at TeV energies with the Whipple 10 m telescope and at X-ray energies with Rossi X-ray Timing Explorer (RXTE) during each clear night within the Whipple observing windows.

Micro Air Vehicles (MAVs) are noted for their small size and low-Reynolds number flight regime. Because they have small mass, they are attractive for use in sensing of toxic plumes. This mission requires high aerodynamic efficiency and the ability to be quickly and easily launched. A variable-sweep wing is investigated to meet these goals. Numerical(More)
We report a possible detection of TeV gamma rays from the Galactic center by the Whipple 10 m gammaray telescope. Twenty-six hours of data were taken over an extended period from 1995 through 2003 resulting in a total significance of 3.7 j. The measured excess corresponds to an integral flux of 8 1.6 # 10 0.5 # above an energy of 2.8 TeV, roughly 40% of the(More)
The blazar 1ES 1959+650 was observed in a flaring state with the Whipple 10 m Imaging Atmospheric Cerenkov Telescope in 2002May. A spectral analysis has been carried out on the data from that time period, and the resulting very high energy gamma-ray spectrum (E 316 GeV) can be well fitted by a power law of differential spectral index 1⁄4 2:78 0:12stat(More)
