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)…

The onset of stellar bars at Cosmic Noon. Bar-driven quenching and AGN co-evolution in a mature disc galaxy

Luca Costantin, Lorenzo Morelli, Cristina Cabello +15

The paper analyzes a barred spiral galaxy at redshift 1.17 using JWST NIRSpec data, showing that the bar formed early (z~5) and contributed to long‑term star‑formation quenching wh…

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…

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…

A Novel high-z submm Galaxy Efficient Line Survey in ALMA bands 3 through 8 -- An ANGELS Pilot

T. J. L. C. Bakx, A. Amvrosiadis, G. J. Bendo +32

We use the Atacama Large sub/Millimetre Array (ALMA) to efficiently observe spectral lines across Bands 3, 4, 5, 6, 7, and 8 at high-resolution (0.5" - 0.1") for 16 bright southern…

A dusty proto-cluster surrounding the binary galaxy HerBS-70 at

Tom J. L. C. Bakx, S. Berta, H. Dannerbauer +38

We report on deep SCUBA-2 observations at 850m and NOEMA spectroscopic measurements at 2 mm of the environment surrounding the luminous, massive ($M_{*} \approx 2 \times 10^{11…
