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…

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 +58

We present first detailed maps of the thermal Sunyaev-Zel'dovich (tSZ) effect on a cluster with the NOrthern Extended Millimeter Array (NOEMA). The high sensitivity of t…

The effect of extended radio emission on SMBH accretion rate estimates

Stergios Amarantidis, Duncan Farrah, Nick Seymour +5

Accretion rates in radio galaxies are typically estimated from optical and total radio flux measurements, incorporating emission from the core, jets, and lobes. These estimates can…

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…

Shared-optical-path VLBI frequency phase transfer from 86 to 258 GHz on an 8600 km baseline: Demonstrated with the APEX and IRAM 30 m telescopes

G. -Y. Zhao, A. L. Roy, J. F. Wagner +24

The receiver N3AR operating at a frequency range between 67 and 116 GHz has been commissioned at the APEX telescope in October 2024. This adds a new low-frequency band for APEX, wi…
