The BINGO project X. Cosmological parameter constraints from HI Intensity Mapping lognormal simulations
Pablo Motta, Filipe B. Abdalla, Camila P. Novaes +12
Context. Building on the transformative success of optical redshift surveys, the emerging technique of neutral hydrogen (HI) intensity mapping (IM) offers a novel probe of large-sc…
Accessing the homogeneity scale with 21 cm intensity mapping surveys
Bruno B. Bizarria, Camila P. Novaes, Felipe Avila +4
The homogeneity scale, , offers a fundamental test of the Cosmological Principle, yet it has not yet been measured with 21cm intensity mapping surveys. A key limitation…
Fast End-to-End Framework for Cosmological Parameter Inference from CMB Data Using Machine Learning
Larissa Santos, Camila P. Novaes, Elisa G. M. Ferreira +1
Precise estimation of cosmological parameters from the cosmic microwave background (CMB) remains a central goal of modern cosmology and a key test of inflationary physics. However,…
First Constraints from Marked Angular Power Spectra with Subaru Hyper Suprime-Cam Survey First-Year Data
Jessica A. Cowell, Joaquin Armijo, Leander Thiele +7
We present the first application of marked angular power spectra to weak lensing data, using maps from the Subaru Hyper Suprime-Cam Year 1 (HSC-Y1) survey. Marked convergence field…
Detectability of the 21 cm signal with BINGO through cross-correlation with photometric surveys
Gabriel A. S. Silva, Camila P. Novaes, Carlos A. Wuensche +11
21 cm intensity mapping (HI IM) can efficiently map large cosmic volumes with good redshift resolution, but systematics and foreground contamination pose major challenges for extra…
Cosmological constraints using Minkowski functionals from the first year data of the Hyper Suprime-Cam
Joaquin Armijo, Gabriela A. Marques, Camila P. Novaes +5
We use Minkowski functionals to analyse weak lensing convergence maps from the first-year data release of the Subaru Hyper Suprime-Cam (HSC-Y1) survey. Minkowski functionals provid…
