Raising the Optical Depth to Reionization with Dark Matter Decay
Yu-Ning Wang, Paulo Montero-Camacho, Ziwei Wang +2
DESI DR2 baryon acoustic oscillation measurements have sharpened a discrepancy with cosmic microwave background (CMB) inferences that can be recast as a preference for a reionizati…
No way ou: Epoch of Reionization Observations Do not Support Large Values of the Optical Depth to Reionization

Recent cosmological analyses combining high-redshift cosmic microwave background (CMB) measurements with low-redshift baryon acoustic oscillation (BAO) data have reported a prefere…
Unveiling the dark matter nature with reionization relics
Yao Zhang, Paulo Montero-Camacho, Catalina Morales-Gutiérrez +3
Dark matter constitutes roughly one-fourth of the Universe, yet its physical nature remains unknown. Warm dark matter (WDM), a class of dark matter candidates, has non-negligible v…
Into the Gompverse: A robust Gompertzian reionization model for CMB analyses
Paulo Montero-Camacho, Yin Li, Marco Barquero-Hernández +3
Cosmic reionization is driven by the formation of sources of ultraviolet photons, and hence it is an intrinsically asymmetric process, where its earlier stages occur at a slower pa…

Tantalizing Evidence of Reionization Relics in the eBOSS DR16 Ly Forest Correlations: a Preference for Early Reionization
Yifan Zheng, Paulo Montero-Camacho, Zheng Cai +1
Cosmic reionization of HI leaves enduring relics in the post-reionization intergalactic medium, potentially influencing the Lyman- (Ly) forest down to redshifts as low as $z…
MUltiplexed Survey Telescope (MUST) Science White Paper I: Overview of Large-Scale Structure Cosmology in the Era of Stage-V Spectroscopic Surveys
Cheng Zhao, Song Huang, Mengfan He +41
The MUltiplexed Survey Telescope (MUST) is a 6.5-meter telescope under development. Dedicated to highly-multiplexed, wide-field spectroscopic surveys, MUST observes over 20,000 tar…
CLAP. I. Resolving miscalibration for deep learning-based galaxy photometric redshift estimation
Qiufan Lin, Hengxin Ruan, Dominique Fouchez +6
Obtaining well-calibrated photometric redshift probability densities for galaxies without a spectroscopic measurement remains a challenge. Deep learning discriminative models, typi…
Reionization relics in the cross-correlation between the Ly forest and 21 cm intensity mapping in the post-reionization era
Paulo Montero-Camacho, Catalina Morales-Gutiérrez, Yao Zhang +2
The tumultuous effects of ultraviolet photons that source cosmic reionization, the subsequent compression and shock-heating of low-density regions, and the modulation of baryons in…
Probing the cosmic web in Ly emission over large scales: an Intensity Mapping forecast for DECaLS/BASS and DESI
Pablo Renard, Daniele Spinoso, Zechang Sun +3
Being the most prominent HI line, Ly permeates the cosmic web in emission. Despite its potential as a cosmological probe, its detection on large scales remains elusive. We prese…
Five parameters are all you need (in CDM)
Paulo Montero-Camacho, Yin Li, Miles Cranmer
The standard cosmological model, with its six independent parameters, successfully describes our observable Universe. One of these parameters, the optical depth to reionization $τ_…
