Reconstructing the galaxy redshift distribution from angular cross power spectra
L. Sun, H. Zhan, C. Tao
The control of photometric redshift (photo-) errors is a crucial and challenging task for precision weak lensing cosmology. The spacial cross-correlations (equivalently, the ang…
Measuring Baryon Acoustic Oscillations from the clustering of voids
Yu Liang, Cheng Zhao, Chia-Hsun Chuang +2
We investigate the necessary methodology to optimally measure the baryon acoustic oscillation (BAO) signal, from voids based on galaxy redshift catalogues. To this end, we study th…
DIVE in the cosmic web: voids with Delaunay Triangulation from discrete matter tracer distributions
Cheng Zhao, Charling Tao, Yu Liang +2
We present a novel parameter-free cosmological void finder (\textsc{dive}, Delaunay TrIangulation Void findEr) based on Delaunay Triangulation (DT), which efficiently computes the…
Improving Cosmological Distance Measurements Using Twin Type Ia Supernovae
H. K. Fakhouri, K. Boone, G. Aldering +41
We introduce a method for identifying "twin" Type Ia supernovae, and using them to improve distance measurements. This novel approach to Type Ia supernova standardization is made p…
Signatures of the Primordial Universe from Its Emptiness: Measurement of Baryon Acoustic Oscillations from Minima of the Density Field
Francisco-Shu Kitaura, Chia-Hsun Chuang, Yu Liang +14
Sound waves from the primordial fluctuations of the Universe imprinted in the large-scale structure, called baryon acoustic oscillations (BAOs), can be used as standard rulers to m…
The extended Baryon Oscillation Spectroscopic Survey (eBOSS): a cosmological forecast
Gong-Bo Zhao, Yuting Wang, Ashley J. Ross +28
We present a science forecast for the eBOSS survey, part of the SDSS-IV project, which is a spectroscopic survey using multiple tracers of large-scale structure, including luminous…
