Forecast of observing time delay of the strongly lensed quasars with Muztagh-Ata 1.93m telescope
Shanhao Zhu, Yiping Shu, Haibo Yuan +8
As a completely independent method, the measurement of time delay of strongly lensed quasars (TDSL) are crucial to resolve the Hubble tension. Extensive monitoring is required but…
Simultaneous B'V'R' Monitoring of BL Lacertae Object S5~0716+714 and Detection of Inter-Band Time Delay
Jianghua Wu, Markus Boettcher, Xu Zhou +3
We present the results of our optical monitoring of the BL Lac object S5 0716+714 on seven nights in 2006 December. The monitoring was carried out simultaneously at three optical w…
M dwarf Stars - The By-Product of X-Ray Selected AGN Candidates
Y. Bai, Y. -C. Sun, X. -T. He +5
X-ray loud M dwarfs are a major source of by-product (contamination) in the X-ray band of the multiwavelength quasar survey (MWQS). As a by-product, the low dispersion spectra of 2…
Strong Lensing Probabilities in a Cosmological Model with a Running Primordial Power Spectrum
Tong-Jie Zhang, Zhi-Liang Yang, Xiang-Tao He
The combination of the first-year Wilkinson Microwave Anisotropy Probe (WMAP) data with other finer scale cosmic microwave background (CMB) experiments (CBI and ACBAR) and two stru…
Observational constraints on cosmology from modified Friedmann equation
Zong-Hong Zhu, Masa-Katsu Fujimoto, Xiang-Tao He
Recent measurements of type Ia supernovae as well as other concordant observations suggest that the expansion of our universe is accelerating. A dark energy component has usually b…
Determining the equation of state of dark energy from angular size of compact radio sources and X-ray gas mass fraction of galaxy clusters
Zong-Hong Zhu, Masa-Katsu Fujimoto, Xiang-Tao He
Using recent measurements of angular size of high-z milliarcsecond compact radio sources compiled by Gurvits, Kellermann and Frey (1999) and X-ray gas mass fraction of galaxy clust…
The largest virialized dark halo in the universe
Wei Zhou, Tong-Jie Zhang, Li Chen +2
Using semi-analytic approach, we present an estimate of the properties of the largest virialized dark halos in the present universe for three different scenarios of structure forma…
