Besides the measurement of ocean surface currents, high-frequency (HF) radar has also been demonstrated to be effective at measuring the wind direction at scales on the order of one to several kilomet...
A Laboratory Demonstration of Coriolis Effects on Wind-Driven Ocean Currents
Wind-Driven Ocean Currents Coriolis Effects
2015/7/20
Here we study the mechanism by which the wind drives ocean circulation. We induce cyclonic and anticyclonic circulation by blowing air over the surface of a rotating tank of water using fans co-rotati...
Depth profiling analysis of solar wind helium collected in diamond-like carbon film from Genesis
solar wind depth profile helium NASA Genesis mission post-ionization
2017/4/10
The distribution of solar-wind ions in Genesis mission collectors, as determined by depth profiling analysis, constrains
the physics of ion-solid interactions involving the solar wind. Thus, they pro...

The correlation of sea surface temperatures, sea level pressure and vertical wind shear with ten tropical cyclones between 1981-2010.
We have examined Chandra observations of the recently discovered X-ray thread G0.13-0.11 in the Galactic center Radio Arc region. Part of the Chandra data was studied by Yusef-Zadeh, Law, & Wardle, wh...
The Chandra View of DA 530: A Subenergetic Supernova Remnant with a Pulsar Wind Nebula?
DA 530 (G93.3+6.9) ISM
2014/12/23
DA 530 (G93.3+6.9) is a high Galactic latitude supernova (SN) remnant with a well-defined shell-like radio morphology and an exceptionally low X-ray-to-radio luminosity ratio. Based on a Chandra ACIS ...
DISTANCE DETERMINATION TO THE CRAB-LIKE PULSAR WIND NEBULA G54.1+0.3 AND THE SEARCH FOR ITS SUPERNOVA REMNANT SHELL

2014/12/23
We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) imag...
Stellar feedback in Galactic bulges plays an essential role in shaping the evolution of galaxies. To quantify this role and facilitate comparisons with X-ray observations, we conduct three-dimensional...
Feedback and Recycled Wind Accretion: Assembling the z = 0 Galaxy Mass Function
Feedback and Recycled Wind Galaxy Mass
2014/12/22
We analyse cosmological hydrodynamic simulations that include observationally-constrained prescriptions for galactic outflows. If these simulated winds accurately represent winds in the real Universe,...
THE RADIO PROPERTIES AND MAGNETIC FIELD CONFIGURATION IN THE CRAB-LIKE PULSAR WIND NEBULA G54.1+0.3
filamentary loop-like structures
2014/12/22
We present a multifrequency radio investigation of the Crab-like pulsar wind nebula (PWN) G54.1+0.3 using the Very Large Array. The high resolution of the observations reveals that G54.1+0.3 has a com...
