Two late-T dwarfs at kiloparsec distances revealed by JWST UNCOVER survey
D. H. Li, Z. H. Zhang, H. H. Peng +3
We conducted a search for brown dwarf candidates in a James Webb Space Telescope deep field around A2744 to investigate the space density of these objects at kiloparsec distances.…
Filtering Interlopers with Photometry and Diagnostic Features: A Machine Learning Framework Validated with CSST Slitless Spectroscopy
Hui Peng, Yu Yu, Yiyang Guo +13
The slitless spectroscopic method employed by missions such as Euclid and the Chinese Space-station Survey Telescope (CSST) faces a fundamental challenge: spectroscopic redshifts d…
Redshift Distributions of Fast Radio Bursts Inferred Using Clustering in Dispersion Measure Space
Hui Peng, Yu Yu
Fast radio bursts (FRBs), millisecond-duration radio transient events, possess the potential to serve as excellent cosmological probes. The FRB redshift distribution contains infor…
Reconstructing redshift distributions with photometric galaxy clustering
Hui Peng, Yu Yu
The accurate determination of the true redshift distributions in tomographic bins is critical for cosmological constraints from photometric surveys. The proposed redshift self-cali…
Precise self-calibration of interloper bias in spectroscopic surveys
Hui Peng, Yu Yu
Interloper contamination due to line misidentification is an important issue in the future low-resolution spectroscopic surveys. We realize that the algorithm previously used for p…
Using angular two-point correlations to self-calibrate the photometric redshift distributions of DECaLS DR9
Haojie Xu, Pengjie Zhang, Hui Peng +7
Calibrating the redshift distributions of photometric galaxy samples is essential in weak lensing studies. The self-calibration method combines angular auto- and cross-correlations…
