An almost NIRCam-dark dusty star-forming galaxy at z = 6.63

L. Bing, Seb Oliver, Mengyuan Xiao, G. Lagache et autres

ABSTRACT We present AC-2168, an almost NIRCam-dark, millimetre-bright galaxy. The source was identified blindly in Atacama Large Millimeter/submillimeter Array (ALMA) Band-4 continuum data and remains undetected in the COSMOS-Web DR1 NIRCam catalogue. We spectroscopically confirm a redshift of $z_{\rm spec}=6.631$ from [${\rm …

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

L. Pantoni, F. Galliano, S. C. Madden, R. Adam et autres

Context. Large dust grains in thermal equilibrium dominate the far-infrared emission of star-forming galaxies and substantially contribute to their millimetre continuum. Constraining dust properties in this regime is challenging due to contamination from free-free and synchrotron emission. Aims. We investigate the spatial …

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

Ji-Xuan Zhou, Nicolas Peretto, A J Rigby, R Adam et autres

ABSTRACT The processes governing protostellar mass growth remain debated, although episodic accretion is now understood as a key feature of protostellar evolution across all masses. Luminosity bursts have been observed in both low- and high-mass protostars, but the overall statistics remain limited, …

Resolved ISM properties and scaling relations in the barred galaxy NGC 3627: constraints from NIKA2 observations

S. Katsioli, E M Xilouris, Florian Galliano, R Adam et autres

ABSTRACT We investigate the interplay between star formation, interstellar medium (ISM) components, and dust properties in NGC 3627 using new NIKA2 1.15 and 2 mm observations from the IMEGIN Large Program. Our goal is to analyse dust and radio emission, decompose contributions …

Blind detection of galaxy clusters in the COSMOS field via the SZ effect

D. Chérouvrier, Rebecca Adam, P. A. R. Ade, H. Ajeddig et autres

Clusters of galaxies are powerful cosmological probes, and the thermal Sunyaev Zel’dovich (tSZ) effect provides an efficient method for their detection. High-angular-resolution observations, such as those provided by the NIKA2 camera on the IRAM 30-m telescope, are essential to target low mass …

NIKA2 maps tracing dust grain evolution in cores of TMC1

A. Joana Kramer, Rebecca Adam, P. A. R. Ade, H. Ajeddig et autres

The Taurus Molecular Cloud TMC1 is a nearby molecular cloud filament exhibiting several dense cores. It has been intensely studied in particular because of its very rich gas phase chemistry. Here, we present NIKA2 observations with the IRAM 30m telescope of its …

Overview of final results from the NIKA2 Sunyaev-Zeldovich Large Program

F. Mayet, Rebecca Adam, P. A. R. Ade, H. Ajeddig et autres

The NIKA2 SZ Large Program (LPSZ) is devoted to the highangular resolution SZ mapping of a representative sample of SZ-selected clusters, at intermediate to high redshift, drawn from the catalogues of the Planck satellite and of the Atacama Cosmology Telescope. Central to …

The SZ-Mass scaling relation with the NIKA2 SZ Large Program

A. Moyer-Anin, Rémi Adam, P. A. R. Ade, H. Ajeddig et autres

In Sunyaev-Zeldovich (SZ) cluster cosmology, accurately determining cluster masses is crucial for constraining cosmological parameters through cluster number counts. As the mass is not an observable, a scaling relation is needed to link cluster masses to the integrated Compton parameter Y, i.e., …

N2CLS: The NIKA2 view of the distant Universe

S. Berta, Rebecca Adam, P. A. R. Ade, H. Ajeddig et autres

The N2CLS survey observed the GOODS-N and COSMOS fields at 260 GHz and 150 GHz with the NIKA2 camera, reaching the confusion limit in GOODS-N at 1.2 mm and approaching it at 2.0 mm. In this short proceedings, we present the results …

Thermal Sunyaev-Zel’dovich effect at the core of CL J1226.9+3332 revealed by NOEMA

M. Muñoz-Echeverría, J. F. Macías–Pérez, R. Neri, É. Pointecouteau et autres

We present first detailed maps of the thermal Sunyaev-Zel’dovich (tSZ) effect on a z = 0.89 cluster with the NOrthern Extended Millimeter Array (NOEMA). The high sensitivity of these observations enabled the effective identification and removal of the millimetre-wave sources contaminating the …

High-precision polarization measurements with lumped element kinetic inductance detectors

S. Savorgnano, A. Catalano, J. F. Macías–Pérez, J. Bounmy et autres

Aims. Our aim with this work is to demonstrate that two arrays of lumped element kinetic inductance detectors, when employed in filled array configuration and separated by an external linear polarizer oriented at 45°, can achieve the precision required by next-generation cosmological …
