Self-Microlensing in Compact Binary Systems
Bo Qin, Xiang-Ping Wu, Zhenlong Zou
The signature of the self-microlensing in compact binaries (white dwarfs, neutron stars and black holes) is a flare with the characteristic time of typically a few minutes. The pro…
Cosmic Ray Protons and Magnetic Fields in Clusters of Galaxies and their Cosmological Consequences
T. A. Ensslin, P. L. Biermann, P. P. Kronberg +1
The masses of clusters of galaxies estimated by gravitational lensing exceed in many cases the mass estimates based on hydrostatic equilibrium. This may suggest the existence of no…
Polarimetry of the Type Ia Supernova SN 1996X
Lifan Wang, J. Craig Wheeler, Peter Hoeflich
We present broad-band and spectropolarimetry of the Type Ia SN 1996X obtained on April 14, 1996 (UT), and broad-band polarimetry of SN 1996X on May 22,1996, when the supernova was…
Asteroseismological Observations of the Central Star of the Planetary Nebula NGC 1501
H. E. Bond, S. Kawaler, R. Ciardullo +17
We report on a global CCD time-series photometric campaign to decode the pulsations of the nucleus of the planetary nebula NGC1501. The star is hot and hydrogen-deficient, similar…
Comparisons of Cluster Mass Determinations by X-ray Observations and Gravitational Lensing
Xiang-Ping Wu, Li-Zhi Fang
Gravitational lensing by clusters of galaxies has been detected on scales ranging from Mpc to Mpc, namely, arcs/arclets, weak lensing and quasar-cluster asso…
Environmental Effect on the Associations of Background Quasars with Foreground Objects: I. Analytic Investigation
Xiang-Ping Wu, Li-Zhi Fang, Zonghong Zhu +1
The associations of the angular positions of background quasars with foreground galaxies, clusters of galaxies and quasars are often attributed to the statistical lensing by gravit…
On the Possible Variations of the Hubble Constant with Distance
Xiang-Ping Wu, Bo Qin, Li-Zhi Fang
Current measurements of the Hubble constant on scale less than Mpc appear to be controversial, while the observations made at high redshift seem to provide a relati…
Polarization of SN 1987A Revisited
Lifan Wang, J. C. Wheeler
The conventional picture for the origin of the polarization of a supernova is based on a model of Thomson or resonance scattering of photons traveling through an aspherical superno…
Quasar-Cluster Associations and Gravitational Lensing by Large-Scale Matter Clumps
Xiang-Ping Wu, Li-Zhi Fang
Motivated by the significant overdensity of background bright quasars recently detected behind the foreground clusters of galaxies on scale of arcminutes, we have investigated…
