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…
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…
Resolved ISM properties and scaling relations in the barred galaxy NGC 3627: constraints from NIKA2 observations
S. Katsioli, E. M. Xilouris, F. Galliano +64
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 IMEGI…
NIKA2 Cosmological Legacy Survey. First measurement of the confusion noise at the IRAM 30 m telescope
N. Ponthieu, F. -X. Désert, A. Beelen +54
The NIKA2 Cosmological Legacy Survey (N2CLS) is a large programme using the NIKA2 dual-band camera on the IRAM 30\,m telescope. Its goal is to improve our understanding of the phys…
The NIKA2 cosmological legacy survey at 2 mm: catalogs, colors, redshift distributions, and implications for deep surveys
M. Béthermin, G. Lagache, C. Carvajal-Bohorquez +54
Millimeter galaxy surveys are particularly effective in detecting dusty star-forming galaxies at high redshift. While such observations are typically conducted at ~1mm, some studie…
Overdense fireworks in GOODS-N: Unveiling a record number of massive dusty star forming galaxies at z5.2 with the N2CLS
G. Lagache, M. Xiao, A. Beelen +59
As part of the N2CLS Survey, we have identified a remarkable overdensity of eight bright dusty star-forming galaxies at z5.2 in the GOODS-N field. Three of these galaxies, N2…
Continuum, CO and Water vapour maps of the Orion Nebula. First millimetre spectral imaging with Concerto
F. -X. Désert, J. F. Macías-Pérez, A. Beelen +60
The millimetre spectrum of Galactic regions and galaxies is rich in continuum and molecular lines. This diversity is mostly explored using either broad-band photometry or high-reso…
A panchromatic view of N2CLS GOODS-N: the evolution of the dust cosmic density since z~7
S. Berta, G. Lagache, A. Beelen +58
(abridged) To understand early star formation, it is essential to determine the dust mass budget of high-redshift galaxies. Sub-millimeter rest-frame emission, dominated by cold du…
Interpreting Millimeter Emission from IMEGIN galaxies NGC 2146 and NGC 2976
G. Ejlali, F. S. Tabatabaei, H. Roussel +59
The millimeter continuum emission from galaxies provides important information about cold dust, its distribution, heating, and role in their InterStellar Medium (ISM). This emissio…
Faint millimeter NIKA2 dusty star-forming galaxies: finding the high-redshift population
L. -J. Bing, A. Beelen, G. Lagache +46
We develop a new framework to constrain the source redshift. The method jointly accounts for the detection/non-detection of spectral lines and the prior information from the photom…
IAS/CEA Evolution of Dust in Nearby Galaxies (ICED): the spatially-resolved dust properties of NGC4254
L. Pantoni, R. Adam, P. Ade +57
We present the first preliminary results of the project \textit{ICED}, focusing on the face-on galaxy NGC4254. We use the millimetre maps observed with NIKA2 at IRAM-30m, as part o…
Exploring the interstellar medium of NGC 891 at millimeter wavelengths using the NIKA2 camera
S. Katsioli, R. Adam, P. Ade +61
In the framework of the IMEGIN Large Program, we used the NIKA2 camera on the IRAM 30-m telescope to observe the edge-on galaxy NGC 891 at 1.15 mm and 2 mm and at a FWHM of 11.1" a…
Constraining Millimeter Dust Emission in Nearby Galaxies with NIKA2: the case of NGC2146 and NGC2976
G. Ejlali, R. Adam, P. Ade +57
This study presents the first millimeter continuum mapping observations of two nearby galaxies, the starburst spiral galaxy NGC2146 and the dwarf galaxy NGC2976, at 1.15 mm and 2 m…
The stratification of ISM properties in the edge-on galaxy NGC 891 revealed by NIKA2
S. Katsioli, E. M. Xilouris, C. Kramer +60
As the millimeter wavelength range remains a largely unexplored spectral region for galaxies, the IMEGIN large program aims to map the millimeter continuum emission of 22 nearby ga…
GASTON: Galactic Star Formation with NIKA2: A new population of cold massive sources discovered
N. Peretto, A. Rigby, R. Adam +43
Understanding where and when the mass of stars is determined is one of the fundamental, mostly unsolved, questions in astronomy. Here, we present the first results of GASTON, the G…
