Vz-GAL Dusty Star-Forming Galaxies: Revisiting the CO-H2 Conversion Factor Tension

Prachi Prajapati, Axel Weiss, Dominik Riechers +17

The CO luminosity-to-H mass conversion factor () remains a debated uncertainty in determining molecular gas masses of high-redshift dusty star-forming galaxies (DSFGs)…

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…

Vz-GAL: Probing Cold Molecular Gas in Dusty Star-forming Galaxies at z=1-6

Prachi Prajapati, Dominik Riechers, Pierre Cox +20

We present the first results of Vz-GAL, a high-redshift CO(J=1-0) large survey with the Karl G. Jansky Very Large Array, targeting 92 Herschel-selected, infrared-luminous, dusty st…

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…

HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo

P. Cox, K. M. Butler, C. R. Keeton +24

We present a study of HerS-3, a dusty star-forming galaxy at zspec = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy s…

NIKA2 Cosmological Legacy Survey: Blind detection of galaxy clusters in the COSMOS field via the Sunyaev-Zel'dovich effect

D. Chérouvrier, J. F. Macias-Perez, F. X. Désert +59

(Abridged) Clusters of galaxies, formed in the latest stages of structure formation, are unique cosmological probes. With the advent of large CMB surveys like those from the Planck…
