Methodological Frontiers in 21-cm Intensity Mapping: the Treatment of Systematics and Foreground Contamination
Marta Spinelli, Matilde Barberi-Squarotti, José Luis Bernal +29
The distribution of neutral hydrogen (HI) in the post-reionization universe traces the cosmic large-scale structure and therefore serves as a powerful cosmological probe. An effici…
Probing Anomalous Microwave Emission with the Square Kilometre Array
Matías Vidal, Simón Casassus, Roke Cepeda-Arroita +15
Anomalous microwave emission (AME) represents an excess of radiation in the 10-60 GHz range, distinct from synchrotron, free-free, or thermal dust emission. Although most commonly…
CosmicWeb-21cm array: A New Radio Observation Array Design for 21cm Cosmology
Jiancheng Wang, Jirong Mao, Xiangming Cheng +10
This paper presents the CosmicWeb-21cm array, a novel radio interferometer designed to overcome the key challenges in 21 cm cosmology. Its core innovations include: (1) a multi-sca…
Spectral Signatures of Spinning Dust from Grain Ensembles in Diverse Environments: A Combined Theoretical and Observational Study
Zheng Zhang, Jens Chluba, Roke Cepeda-Arroita +1
Recent observations of anomalous microwave emission (AME) reveal spectral features that are not readily reproduced by spinning dust models. We examine how dust grain distributions…
Joint Bayesian calibration and map-making for intensity mapping experiments
Zheng Zhang, Philip Bull, Mario G. Santos +1
Line-intensity mapping (LIM) is an emerging cosmological technique that traces large-scale structure through the integrated spectral-line emission of unresolved sources. Reconstruc…
A general polynomial emulator for cosmology via moment projection
Zheng Zhang
We present MomentEmu, a general-purpose polynomial emulator for fast and interpretable mappings between theoretical parameters and observational features. The method constructs mom…
