We report VLA detections at 1.3, 2, and 3.6 cm of the Egg Nebula, RAFGL 2688. We resolve the source and find an inner 9&arcsec; diameter core that is produced by approximately 0.01 M middle dot in circle of dust. It seems that the Egg Nebul...

We report the recovery of a spectroscopic event in eta Carinae in 1997/1998 after a prediction by Damineli in 1996. A true periodicity with P=2020+/-5 days (0.2% uncertainty) is obtained. The line intensities and the radial velocity curve d...
A Theoretical Light-Curve Model for the 1999 Outburst of U Scorpii [0.03%]

I Hachisu I et al.
A theoretical light curve for the 1999 outburst of U Scorpii is presented in order to obtain various physical parameters of the recurrent nova. Our U Sco model consists of a very massive white dwarf (WD) with an accretion disk and a lobe-fi...
The Rapid X-Ray Variability of V4641 Sagittarii (SAX J1819.3-2525 = XTE J1819-254) [0.03%]

We report on the rapid X-ray variability of the variable star and X-ray transient V4641 Sagittarii (SAX J1819.3-2525 = XTE J1819-254) as observed on 1999 September 15 by the proportional counter array (PCA) on board the Rossi X-Ray Timing E...
The Ejection of Relativistic Bullets from Supernovae and the Generation of Gamma-Ray Bursts [0.03%]

It is generally believed that cosmological gamma-ray bursts (GRBs) are produced by the deceleration of relativistic objects with Gamma greater, similar100. We study the possibility that some GRBs are produced along with relativistic matter ...
Radio Emission from Three-dimensional Relativistic Hydrodynamic Jets: Observational Evidence of Jet Stratification [0.03%]
三维相对论性流体喷流的射电辐射:观测到喷流结构分层现象的证据
MA Aloy,JL Gómez,JM Ibáñez et al.
MA Aloy et al.
We present the first radio emission simulations from high-resolution three-dimensional relativistic hydrodynamic jets; these simulations allow us to study the observational implications of the interaction between the jet and the external me...
New CO and Millimeter Continuum Observations of the z = 2.394 Radio Galaxy 53W002 [0.03%]
射电星系53W002的红移z=2.394的CO和毫米连续谱新观测结果

The z=2.39 radio galaxy 53W002 lies in a cluster of Lyalpha emission-line objects and may itself be undergoing a major burst of star formation. CO (3-2) emission, at 102 GHz, was detected from 53W002 in 1997 by Scoville et al., who also rep...

The current models of early star and galaxy formation are based upon the hierarchical growth of dark matter halos, within which the baryons condense into stars after cooling down from a hot diffuse phase. The latter is replenished by infall...

Cosmological simulations predict that a large fraction of the baryonic mass of the universe exists as 105-107 K diffuse, X-ray-emitting gas, tracing low-density filament and sheetlike structures exterior to massive clusters of galaxies. If ...

If the mean properties of clusters of galaxies are well described by the entropy-driven model, the distortion induced by the cluster population on the blackbody spectrum of the cosmic microwave background radiation is proportional to the to...
