BayeSED-GALAXIES II. Bayesian full spectrum analysis of galaxies and application in the CSST wide-field slitless spectroscopy survey
Yunkun Han, Xian Zhong Zheng, Xiaohu Yang +21
The China Space Station Telescope (CSST) will conduct wide-field multiband photometric imaging and slitless spectroscopic surveys, advancing cosmology and galaxy evolution studies.…
A dark energy parameterization independent constraint of the spatial curvature
Zhennan Li, Pengjie Zhang
Determining the spatial curvature of the Universe has long been crucial in cosmology. In practice, this effort is often entangled with assumptions of dark energy. A combinati…
Approaching the Cramer-Rao Bound in Weak Lensing with PDF Symmetrization
Jun Zhang, Pengjie Zhang, Wentao Luo
Weak lensing statistics is typically measured as weighted sum of shear estimators or their products (shear-shear correlation). The weighting schemes are designed in the hope of min…
The BigBOSS Experiment
D. Schlegel, F. Abdalla, T. Abraham +138
BigBOSS is a Stage IV ground-based dark energy experiment to study baryon acoustic oscillations (BAO) and the growth of structure with a wide-area galaxy and quasar redshift survey…
The exact analytical solution of the linear structure growth rate in LCDM cosmology and its cosmological applications
Pengjie Zhang
We derive the exact analytical solution of the linear structure growth rate in LCDM cosmology with flat or curved geometry, under the Newtonian gauge. Unlike the well known solutio…
Self calibration of galaxy bias in spectroscopic redshift surveys of baryon acoustic oscillations
Pengjie Zhang
Baryon acoustic oscillation (BAO) is a powerful probe on the expansion of the universe, shedding light on elusive dark energy and gravity at cosmological scales. BAO measurements t…
