Tomographer: End-to-end Redshift Distribution Estimation for Source Catalogs and Intensity Maps
Yi-Kuan Chiang, Yu Voon Ng, Yu-Ren Lin +2
Redshift information is central to nearly every extragalactic and cosmological application of sky surveys, yet only a small fraction of cataloged sources, and none of the photons f…
Weak lensing scattering transform: dark energy and neutrino mass sensitivity
Sihao Cheng, Brice Ménard
As weak lensing surveys become deeper, they reveal more non-Gaussian aspects of the convergence field which can only be extracted using statistics beyond the power spectrum. In Che…
The thermal and gravitational energy densities in the large-scale structure of the Universe
Yi-Kuan Chiang, Ryu Makiya, Eiichiro Komatsu +1
As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized. We therefore expect a connection between the me…
Extracting the main trend in a dataset: the Sequencer algorithm
Dalya Baron, Brice Ménard
Scientists aim to extract simplicity from observations of the complex world. An important component of this process is the exploration of data in search of trends. In practice, how…
The Cosmic Thermal History Probed by Sunyaev-Zeldovich Effect Tomography
Yi-Kuan Chiang, Ryu Makiya, Brice Ménard +1
The cosmic thermal history, quantified by the evolution of the mean thermal energy density in the universe, is driven by the growth of structures as baryons get shock heated in col…
A new approach to observational cosmology using the scattering transform
Sihao Cheng, Yuan-Sen Ting, Brice Ménard +1
Parameter estimation with non-Gaussian stochastic fields is a common challenge in astrophysics and cosmology. In this paper, we advocate performing this task using the scattering t…
