CONCERTO: Forward modelling of interferograms for calibration

A. P. Lundgren, A. Beelen, G. Lagache, F.–X. Désert et autres

Context . The CarbON [CII] line in post-rEionisation and ReionisaTiOn epoch (CONCERTO) instrument was a low-resolution mapping Fourier-transform spectrometer based on lumped-element kinetic inductance detector (LEKID) technology that operated at 130-310 GHz. It was installed on the 12-meter APEX telescope in Chile …

Continuum, CO, and water vapour maps of the Orion Nebula

F.–X. Désert, J. F. Macías–Pérez, A. Beelen, A. Benoît et autres

Context. 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-resolution heterodyne spectroscopy. Aims. We aim to map the millimetre continuum emission of Galactic regions with …

CONCERTO: instrument model of Fourier transform spectroscopy, white-noise components

A. Fasano, P. A. R. Ade, Manuel Aravena, Emilio Barria et autres

Modern astrophysics relies on intricate instrument setups to meet the demands of sensitivity, sky coverage, and multi-channel observations. An example is the CONCERTO project, employing advanced technology like kinetic inductance detectors and a Martin-Puplett interferometer. This instrument, installed at the APEX telescope …

CONCERTO at APEX -- On-sky performance in continuum

Wenkai Hu, A. Beelen, G. Lagache, A.N. Fasano et autres

We present the data-processing algorithms and the performance of CONCERTO (CarbON CII line in post-rEionisation and ReionisaTiOn epoch) in continuum by analysing the data from the commissioning and scientific observations. The beam pattern is characterized by an effective FWHM of 31.9 $\pm$ …

Correcting estimations of copepod volume from two‐dimensional images

C. Dubois, Jean‐Olivier Irisson, Éric Debreuve

Abstract Accurate plankton biomass estimations are essential to study marine ecological processes and biogeochemical cycles. This is particularly true for copepods, which dominate mesozooplankton. Such estimations can efficiently be computed from organism volume estimated from images. However, imaging devices only provide two‐dimensional …

The MUSEHubbleUltra Deep Field Survey

N. Bouché, Shy Genel, Alisson Pellissier, C. Dubois et autres

We investigate the specific angular momentum (sAM)j(<r) profiles of intermediate redshift (0.4 < z < 1.4) star-forming galaxies (SFGs) in the relatively unexplored regime of low masses (down toM⋆ ∼ 108 M⊙) and small sizes (down toRe ∼ 1.5 kpc), and we …

The synthetic Emission Line COSMOS catalogue: Hα and [O ii ] galaxy luminosity functions and counts at 0.3 < z < 2.5

Shun Saito, Sylvain de la Torre, O. Ilbert, C. Dubois et autres

ABSTRACT Star-forming galaxies with strong nebular and collisional emission lines are privileged target galaxies in forthcoming cosmological large galaxy redshift surveys. We use the COSMOS2015 photometric catalogue to model galaxy spectral energy distributions and emission-line fluxes. We adopt an empirical but physically …

The COSMOS2015 galaxy stellar mass function

I. Davidzon, O. Ilbert, C. Laigle, J. Coupon et autres

We measure the stellar mass function (SMF) and stellar mass density of galaxies in the COSMOS field up to z ~ 6. We select them in the near-IR bands of the COSMOS2015 catalogue, which includes ultra-deep photometry from UltraVISTA-DR2, SPLASH, and Subaru/Hyper …

We measure the stellar mass function (SMF) of galaxies in the COSMOS field up to $z\sim6$. We select them in the near-IR bands of the COSMOS2015 catalogue, which includes ultra-deep photometry from UltraVISTA-DR2, SPLASH, and Subaru/Hyper-SuprimeCam. At $z>2.5$ we use new precise …
