Cosmological parameters derived from the final (PR4) Planck data release
M. Tristram, A. J. Banday, M. Douspis +10
We present constraints on cosmological parameters using maps from the last Planck data release (PR4). In particular, we detail an upgraded version of the cosmic microwave backgroun…
CONCERTO: Extracting the power spectrum of the [C II ] emission line
M. Van Cuyck, N. Ponthieu, G. Lagache +21
CONCERTO is the first experiment to perform a [CII] line intensity mapping survey to target . Measuring the [CII] power spectrum allows us to study the role of dusty star-fo…
Extragalactic CO emission lines in the CMB experiments: a forgotten signal and a foreground
Abhishek S. Maniyar, Athanasia Gkogkou, William R. Coulton +3
High resolution cosmic microwave background (CMB) experiments have allowed us to precisely measure the CMB temperature power spectrum down to very small scales (multipole $\ell \si…
CONCERTO: Simulating the CO, [CII], and [CI] line emission of galaxies in a 117 field and the impact of field-to-field variance
A. Gkogkou, M. Béthermin, G. Lagache +29
In the submm regime, spectral line scans and line intensity mapping (LIM) are new promising probes for the cold gas content and star formation rate of galaxies across cosmic time.…
Candidate cosmic filament in the GJ526 field, mapped with the NIKA2 camera
J. -F. Lestrade, F. -X. Desert, G. Lagache +44
Distinctive large-scale structures have been identified in the spatial distribution of optical galaxies up to redshift z ~ 1. In the more distant universe, the relationship between…
Multi-probe analysis of the galaxy cluster CL J1226.9+3332: Hydrostatic mass and hydrostatic-to-lensing bias
M. Muñoz-Echeverría, J. F. Macías-Pérez, G. W. Pratt +50
The precise estimation of the mass of galaxy clusters is a major issue for cosmology. Large galaxy cluster surveys rely on scaling laws that relate cluster observables to their mas…
