Micron-sized hydrogel cubes show highly efficient delivery of a potent anti-cancer drug
Micron-sized hydrogel cubes highly efficient delivery anti-cancer drug
2017/7/24
Many potent anti-cancer drugs have major drawbacks — they fail to mix with water, which means they will have a limited solubility in blood, and they lack selectivity to cancer cells.Researchers at the...
Micron-scale d13C determination by NanoSIMS in a Juina diamond with a carbonate inclusion
sub-lithospheric diamonds Juina carbonate lower mantle peridotite eclogite
2017/4/10
Juina diamonds present a wide spectrum of mineral inclusions, covering both peridotitic and eclogitic composition.
Among the most rare inclusions, carbonates are interpreted as an evidence of deep re...
Highly Tm-doped silicate glasses and fibers were developed, which exhibit a high slope efficiency of 68.3% and a gain per unit length of greater than 2dB/cm. Single frequency fiber lasers with laser l...
The clustering dipole of the local universe from the Two Micron All Sky Survey
galaxies clusters
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for investigating the galaxies populating the local universe. A full charact...
A Two Micron All Sky Survey view of the Sagittarius dwarf galaxy. I. Morphology of the Sagittarius core and tidal arms
the Sagittarius core tidal arms
2014/12/24
We present the first all-sky view of the Sagittarius (Sgr) dwarf galaxy mapped by M-giant star tracers detected in the complete Two Micron All Sky Survey (2MASS). Near-infrared photometry of Sgr's pro...
A Two Micron All Sky Survey view of the Sagittarius dwarf galaxy. II. Swope telescope spectroscopy of M giant stars in the dynamically cold Sagittarius tidal stream
kinematics halo
2014/12/24
We have obtained moderate resolution (~6 km s-1) spectroscopy of several hundred M giant candidates selected from Two Micron All Sky Survey photometry. Radial velocities are presented for stars mainly...
The galaxy angular correlation functions and power spectrum from the Two Micron All Sky Survey
general statistics
2014/12/24
We calculate the angular correlation function of galaxies in the Two Micron All Sky Survey. We minimize the possible contamination by stars, dust, seeing, and sky brightness by studying their cross co...
Nature and completeness of galaxies detected in the Two Micron All Sky Survey
surveys general fundamental parameters.
2014/12/24
The Two Micron All Sky Survey (2MASS) provides the most comprehensive data set of near-infrared galaxy properties. We cross correlate the well-defined and highly complete spectroscopic selection of ov...
SuperCam: a 64-pixel heterodyne imaging array for the 870-micron atmospheric window (Proceedings Paper)
Heterodyne imaging arrays submillimeter molecular spectroscopy
2014/12/23
We report on the development of SuperCam, a 64 pixel, superheterodyne camera designed for operation in the astrophysically important 870 μm atmospheric window. SuperCam will be used to answer fundamen...
One-micron spectroscopic studies of accretion and outflow in T Tauri stars
High resolution spectrum Classical T Taurus Stars Spectrum Air calibrator The stars
2014/12/9
High-resolution spectroscopy of classical T Tauri stars (CTTS) at one micron yields new insight into the interaction of accretion disks, outflowing gas, and the central stars. Eighty-one 0.95–1.12 μm ...
First Science Observations with SOFIA/FORCAST: 6 to 37 micron Imaging of the Central Orion Nebula
First Science Observations SOFIA/FORCAST micron Central Orion Nebula
2012/2/23
We present new mid-infrared images of the central region of the Orion Nebula using the newly commissioned SOFIA airborne telescope and its 5 -- 40 micron camera FORCAST. The 37.1 micron images represe...
Searching for Saturn's Dust Swarm: Limits on the size distribution of Irregular Satellites from km to micron sizes
Solar System: satellites
2011/10/8
We describe a search for dust created in collisions between the Saturnian irregular satellites using archival \emph{Spitzer} MIPS observations. Although we detected a degree scale Saturn-centric exces...
A Halo Model of Local IRAS Galaxies Selected at 60 Micron Using Conditional Luminosity Functions
Local IRAS Galaxies Selected 60 Micron
2011/1/11
Using conditional luminosity functions (CLFs) which encode the luminosity distribution of galaxies as a function of halo mass, we construct a halo model of IRAS galaxies selected at 60 micron. An abun...
The 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?
