The HST-Hyperion Survey: Environmental Imprints on the Stellar-Mass Function at z~2.5
Derek Sikorski, Ben Forrest, Brian C. Lemaux +19
Not all galaxies at Cosmic Noon evolve in the same way. It remains unclear how the local environment -- especially the extreme overdensities of protoclusters -- affects stellar mas…
The HST-Hyperion Survey: Companion Fraction and Overdensity in a z ~ 2.5 Proto-supercluster
F. Giddings, B. C. Lemaux, B. Forrest +22
We present a study of the galaxy merger and interaction activity within the Hyperion Proto-supercluster at z~2.5 in an effort to assess the occurrence of galaxy mergers and interac…
Environmental Regulation of Dust and Star Formation Unveiled by Subaru Dual Narrow-band Imaging: Degree-scale Balmer Decrement Mapping across a z = 0.9 Supercluster
Zhaoran Liu, Tadayuki Kodama, Brian C. Lemaux +13
We present results from a dual narrow-band imaging survey targeting the CL1604 supercluster at z = 0.9 using the Subaru Telescope. By combining the NB921 filter on HSC and the NB12…
LATIS: Comparing Galaxy and IGM Tomography Maps as Tracers of Large-scale Structure and Protoclusters at
Andrew B. Newman, Nima Chartab, Mahdi Qezlou +11
We investigate the consistency of intergalactic medium (IGM) tomography and galaxy surveys as tracers of the cosmic web and protoclusters at . We use maps from the Ly$Î…
LATIS: A Sample of IGM-selected Protoclusters and Protogroups at
Andrew B. Newman, Mahdi Qezlou, Gwen C. Rudie +11
The Ly Tomography IMACS Survey (LATIS) has produced large 3D maps of the intergalactic medium (IGM), providing a new window on the cosmic web at . A key advantage of…
Gas properties as a function of environment in the proto-supercluster Hyperion at z ~ 2.45
G. Gururajan, O. Cucciati, B. C. Lemaux +26
The cosmic star-formation rate density, molecular gas density and the AGN activity of the Universe peak at z~ 2-3, showing the Universe is most active at this epoch. The nature of…
