Status of the COSmological Microwave Observations CALibrator

L. Mousset, J. Aumont, S. Berta +33

As the sensitivity of CMB telescopes increases, the need for precise calibration becomes critical. Started in 2022, the COSMOCal project aims to place an artificial polarized sourc…

CONCERTO: forward modeling of interferograms for calibration

A. Lundgren, A. Beelen, G. Lagache +36

The CarbON [CII] line in post-rEionisation and ReionisaTiOn epoch (CONCERTO) instrument is a low-resolution mapping Fourier-transform spectrometer, based on lumped-element kinetic…

The NIKA2 Cosmological Legacy Survey in COSMOS: Final 1.2mm and 2mm source catalogs and redshift distribution of dusty star-forming galaxies

C. R. Carvajal-Bohorquez, G. Lagache, A. Beelen +64

We present the final 1.2mm and 2mm source catalogs and the redshift distribution of the mm-selected population from the NIKA2 Cosmological Legacy Survey (N2CLS) in the COSMOS field…

First Dark Photon Search Results from the Dandelion Experiment

I. Ourahou, S. Savorgnano, C. Beaufort +9

This paper presents the first results from the Dandelion experiment, a directional detection, which searches for 1 meV dark photon dark matter. We use a spherical mirror to convert…

GASTON-GP: Source catalogue and millimetre variability of massive protostellar objects

Ji-Xuan Zhou, Nicolas Peretto, A. J. Rigby +56

The processes governing protostellar mass growth remain debated, although episodic accretion is now understood as a key feature of protostellar evolution across all masses. Luminos…

Spatially-resolved interstellar dust properties in the face-on spiral galaxy M 99 as observed by NIKA2

L. Pantoni, F. Galliano, S. C. Madden +62

Large dust grains in thermal equilibrium dominate the far-infrared and contribute to the millimetre continuum of star-forming galaxies, but constraining their properties is difficu…
