New Tests of the Cosmic Distance Duality Relation with DESI 2024 Baryon Acoustic Oscillation Observations

open access: yesThe Astrophysical Journal
In this paper, we test the cosmic distance duality relation (CDDR), as required by the Etherington reciprocity theorem, which connects the angular diameter distance and the luminosity distance via the relation D _L ( z ) =  D _A ( z )(1 +  z ) ^2 .

HEROES: The Hawaii eROSITA Ecliptic Pole Survey Catalog

open access: yesThe Astrophysical Journal Supplement Series, 2023
We present a seven-band ( g , r , i , z , y , NB816, NB921) catalog derived from a Subaru Hyper Suprime-Cam (HSC) imaging survey of the North Ecliptic Pole (NEP).

Against interpretive exclusivism* Contre l'exclusivisme interprétatif

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Interpretive exclusivism is the dogma that we can only understand cultural systems by interpreting them, thereby ruling out causal explanations of cultural phenomena using scientific methods, for example based on measurement, comparison, and experiment.

Cross-correlation Techniques to Mitigate the Interloper Contamination for Line Intensity Mapping Experiments

open access: yesThe Astrophysical Journal
Line intensity mapping (LIM) serves as a potent probe in astrophysics, relying on the statistical analysis of integrated spectral line emissions originating from distant star-forming galaxies.

Constraining the Break of Spatial Diffeomorphism Invariance with Planck Data

open access: yes, 2017
The current most accepted paradigm for the early universe cosmology, the inflationary scenario, shows a good agreement with the recent Cosmic Microwave Background (CMB) and polarization data.

The Ancient Maya Script of Hand Forms Embedded in Figural Art: A Decipherment of Numerals Signed by the Rulers of Altar Q1

open access: yesTransactions of the Philological Society, EarlyView.
Abstract Ancient Maya texts are informationally dominated by hieroglyphic inscriptions and visually dominated by figural art with distinctly formed hands. The hands suggest iconographically embedded hand signs, which would constitute a unique modality of semantic expression and a discourse complement to hieroglyphic writing.

Revisiting the Hubble Constant, Sound Horizon, and Cosmography from Late-time Universe Observations

open access: yesThe Astrophysical Journal
The Hubble tension has become one of the central problems in cosmology. In this work, we determine the Hubble constant H _0 and sound horizon r _d by using the combination of baryon acoustic oscillations (BAOs) from DESI surveys, time-delay lensed ...

New Observational H(z) Data from Full-spectrum Fitting of Cosmic Chronometers in the LEGA-C Survey

open access: yesThe Astrophysical Journal Supplement Series, 2023
In this work, we perform a full-spectrum fitting of 350 massive and passive galaxies selected as cosmic chronometers from the LEGA-C ESO public survey to derive their stellar ages, metallicities, and star formation histories.
