Description
The NIKA2 Cosmological Legacy Survey (N2CLS) observed the GOODS-N and COSMOS fields with the NIKA2 millimeter camera at the 30m IRAM telescope on the Sierra Nevada.
On behalf of the N2CLS team, I will present the survey and its early results. The deep GOODS-N NIKA2 maps are close to the photometric confusion limit in both the 2.0 and 1.2 millimeter bands. A total of 120 and 67 sources in the 159 arcmin2 GOODS-N and 301 and 124 sources in the 1010 arcmin2 COSMOS maps are detected at 1.2 and 2.0 mm, respectively.
Number counts are defined with unprecedented precision and are compared, along with galaxy colors, to the predictions of the Simulated Infrared Dusty Extragalactic Sky (SIDES).
The NIKA2 GOODS-N catalog was matched to the rich multi-wavelength data set available from the X-rays to radio frequencies, including Chandra, JWST, HST, Spitzer, Herschel, VLA, and more. The finely sampled spectral energy distributions of the GOODS-N NIKA2 sources were modeled with state of the art methods, including stellar, dust, synchrotron and AGN-torii components. Among the many derived quantities, I will talk about their dust mass, defining for the first time the evolution of the galaxy dust mass function and dust cosmic density up to redshift z~7.
Finally, I will discuss the dust and gas properties of the intriguing overdensity of star forming galaxies at z~5.2 star forming galaxies identified in GOODS-N.
