The XXL Survey XLIV. Sunyaev-Zel'dovich mapping of a low-mass cluster at z~1: a multi-wavelength approach

M. Ricci, R. Adam, D. Eckert +62

In this paper, we present resolved observations of the Sunyaev-Zel'dovich (SZ) effect, obtained with the NIKA2 camera, towards the cluster of galaxies XLSSC102, a relatively low-ma…

Dynamics of cluster-forming hub-filament systems: The case of the high-mass star-forming complex Monoceros R2

S. P. Trevino-Morales, A. Fuente, A. Sanchez-Monge +15

High-mass stars and star clusters commonly form within hub-filament systems. Monoceros R2, harbors one of the closest such systems, making it an excellent target for case studies.…

The molecular gas mass of M33

P. Gratier, J. Braine, K. Schuster +15

[Abridged] Do some environments favor efficient conversion of molecular gas into stars? To answer this, we need to be able to estimate the H2 mass. Traditionally, this is done usin…

CII, CI, and CO in the massive star forming region W3 Main

C. Kramer, H. Jakob, B. Mookerjea +3

We have used the KOSMA 3m telescope to map the core 7'x5' of the Galactic massive star forming region W3Main in the two fine structure lines of atomic carbon and four mid-J transit…

First polarised light with the NIKA camera

A. Ritacco, R. Adam, A. Adane +39

NIKA is a dual-band camera operating with 315 frequency multiplexed LEKIDs cooled at 100 mK. NIKA is designed to observe the sky in intensity and polarisation at 150 and 260 GHz fr…

Dust heating sources in galaxies: the case of M33 (HERM33ES)

M. Boquien, D. Calzetti, F. Combes +7

Dust emission is one of the main windows to the physics of galaxies and to star formation as the radiation from young, hot stars is absorbed by the dust and reemitted at longer wav…

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…

Unveiling The Physics of Star Formation and Feedback in Galaxies

F. S. Tabatabaei, J. Braine, C. Kramer +3

Recent studies show the importance of feedback in the evolution of the star formation rate in the Universe. However, the nature and physics of the feedback are still pressing quest…

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…

A multi-instrument non-parametric reconstruction of the electron pressure profile in the galaxy cluster CLJ1226.9+3332

C. Romero, M. McWilliam, J. -F. Macıas-Perez +36

Context: In the past decade, sensitive, resolved Sunyaev-Zel'dovich (SZ) studies of galaxy clusters have become common. Whereas many previous SZ studies have parameterized the pres…

Gas morphology and energetics at the surface of PDRs: new insights with Herschel observations of NGC 7023

C. Joblin, P. Pilleri, J. Montillaud +37

We investigate the physics and chemistry of the gas and dust in dense photon-dominated regions (PDRs), along with their dependence on the illuminating UV field. Using Herschel-HIFI…

100 mum and 160 mum emission as resolved star-formation rate estimators in M33 (HERM33ES)

M. Boquien, D. Calzetti, C. Kramer +17

Over the past few years several studies have provided estimates of the SFR (star-formation rate) or the total infrared luminosity from just one infrared band. However these relatio…

A NIKA view of two star-forming infrared dark clouds: Dust emissivity variations and mass concentration

A. J. Rigby, N. Peretto, R. Adam +39

The thermal emission of dust grains is a powerful tool for probing cold, dense regions of molecular gas in the ISM, and so constraining dust properties is key to obtaining accurate…
