Galaxy clusters approximate a planar distribution in a three-dimensional parameter space that can be characterized, for example, by an optical luminosity, half-light radius, and X-ray luminosity. We find the nearest neighbor clusters for th...
The Discovery of a High-Redshift Quasar without Emission Lines from Sloan Digital Sky Survey Commissioning Data [0.03%]
从SDSS试观测数据发现的一个高红移无发射线类星体
X Fan,MA Strauss,JE Gunn et al.
X Fan et al.
We report observations of a luminous unresolved object at redshift z=4.62, with a featureless optical spectrum redward of the Lyalpha forest region, discovered from Sloan Digital Sky Survey commissioning data. The redshift is determined by ...
In Search of Emerging Magnetic Flux underneath the Solar Surface with Acoustic Imaging [0.03%]

With the method of acoustic imaging in helioseismology, we study an emerging flux region, NOAA 7978, using data taken with instruments of the Taiwan Oscillation Network (TON) and the Michelson Doppler Imager (MDI). Phase-shift maps of NOAA ...
Origin of the Universal Correlation between the Flare Temperature and the Emission Measure for Solar and Stellar Flares [0.03%]
太阳耀斑和恒星耀斑的 flare temperature 和 emission measure 之间普适相关性的起源

K Shibata
We present a theory to explain the observed universal correlation between flare temperature T and emission measure EM=n2V for solar and stellar flares (including solar microflares observed by Yohkoh as well as protostellar flares observed b...
Turbulent Convection: Comparing the Moment Equations to Numerical Simulations [0.03%]
湍流对流：动理学方程与数值模拟的比较研究

The nonlocal hydrodynamic moment equations for compressible convection are compared to numerical simulations. Convective and radiative flux typically deviate less than 20% from the three-dimensional simulations, while mean thermodynamic qua...
The ISO/SWS Spectrum of IRC +10216: The Vibrational Bands of C2H2 and HCN [0.03%]
红外源体IRC+10216的ISO/SWS光谱：C2H2和HCN振动带
J Cernicharo,I Yamamura I,E González-Alfonso et al.
J Cernicharo et al.
We present the Infrared Space Observatory/Short-Wavelength Spectrometer full grating resolution spectrum of IRC +10216, which is dominated by strong absorption/emission bands of C2H2 and HCN. All C2H2 bands and the strong near-infrared stre...
A New Supernova Remnant Coincident with the Slow X-Ray Pulsar AX J1845-0258 [0.03%]

BM Gaensler
We report on Very Large Array observations in the direction of the recently discovered slow X-ray pulsar AX J1845-0258. In the resulting images, we find a 5&arcmin; shell of radio emission; the shell is linearly polarized with a nonthermal ...
The Complex Phase-Lag Behavior of the 3-12 Hz Quasi-Periodic Oscillations during the Very High State of XTE J1550-564 [0.03%]

DW Koerner et al.
We present Keck near-infrared imaging of three binary L dwarf systems, all of which are likely to be substellar. Two are lithium dwarfs, and a third exhibits an L7 spectral type, making it the coolest binary known to date. All have componen...
