Multi-wavelength consensus of large-scale linear bias
Hengxing Pan, Danail Obreschkow, Cullan Howlett +4
We model the large-scale linear galaxy bias as a function of redshift and observed absolute magnitude threshold for broadband continuum emission from the far inf…

Measuring the HI mass function below the detection threshold
Hengxing Pan, Matt J. Jarvis, James R. Allison +5
We present a Bayesian Stacking technique to directly measure the HI mass function (HIMF) and its evolution with redshift using galaxies formally below the nominal detection thresho…

Group connectivity in COSMOS: a tracer of mass assembly history
E. Darragh-Ford, C. Laigle, G. Gozaliasl +11
Cosmic filaments are the channel through which galaxy groups assemble their mass. Cosmic connectivity, namely the number of filaments connected to a given group, is therefore expec…
