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)…
Cosmic evolution of the [CII]-to-molecular gas relation
Cédric Accard, Florent Renaud, Katarina Kraljic +3
The [CII] 158 m line is widely used to trace star formation and the gas contents of high-redshift galaxies. However, it remains unclear under which physical conditions it relia…
Starbursts hiding in the main sequence: a pathway toward quenching?
Florent Renaud, Katarina Kraljic, Jonathan Freundlich +10
Star-forming galaxies spend most of their lifetimes on the star-forming main sequence, which establishes a tight empirical and statistical relation between stellar mass and star-fo…
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…
The dust emissivity index beta in infrared-bright galaxies at 1.5 < z < 4.2
G. J. Bendo, T. J. L. C. Bakx, H. S. B. Algera +16
We have measured the dust emissivity index beta for 21 infrared-bright sources (including several gravitationally lensed galaxies) at 1.5 < z < 4.2 using Atacama Large Millimeter/s…
