The Evolution of the SFR-M_* relation at 0.1<z<4: Environmental and Morphological Dependencies
Kaimin He, Ke Shi, Jun Toshikawa +2
We present a comprehensive study of the relationship between star formation rate (SFR) and stellar mass (M_*) from z = 0.1 to z = 4 using a mass-complete sample of approximately 29…
Narrowband Imaging of a z=3.24 Protocluster: Insights from [O III] Emitting Galaxies
Ke Shi, Jun Toshikawa, XianZhong Zheng +2
We present a narrowband imaging on a spectroscopically confirmed protocluster ``D4UD01'' at z=3.24 using CFHT/WIRCam. We identify a sample of 24 [O III] emission line galaxies in t…
Nature vs. Nurture: Revisiting the environmental impact on star formation activities of galaxies
Ke Shi, Nicola Malavasi, Jun Toshikawa +1
We present a systematic study of the environmental impact on star formation activities of galaxies using a mass-complete sample of 170k galaxies at from the latest COSM…
The Role of Dust, UV Luminosity and Large-scale Environment on the Escape of Lya Photons: A Case Study of a Protocluster field at z = 3.1
Yun Huang, Kyoung-Soo Lee, Ke Shi +3
We present a detailed characterization of the Lya properties for 93 Lya emitters (LAEs) at z~3.1 selected from the D1 field of the Canada-France-Hawaii-Telescope Legacy Survey, inc…
Lyman Alpha line properties at and their environmental dependence: a case study around a massive proto-cluster
Nicola Malavasi, Kyoung-Soo Lee, Arjun Dey +3
Ly-emitting galaxies (LAEs) are easily detectable in the high-redshift Universe and are potentially efficient tracers of large scale structure at early epochs, as long as their…
Accelerated galaxy growth and environmental quenching in a protocluster at z=3.24
Ke Shi, Jun Toshikawa, Kyoung-Soo Lee +3
We present a multiwavelength study of galaxies around D4UD01, a spectroscopically confirmed protocluster at z = 3.24 to investigate environmental trends. 450 galaxies are selected…
How Do Galaxies trace a large scale structure?: A case study around a massive protocluster at
Ke Shi, Yun Huang, Kyoung-Soo Lee +7
In the hierarchical theory of galaxy formation, a galaxy overdensity is a hallmark of a massive cosmic structure. However, it is less well understood how different types of galaxie…
A census of galaxy constituents in a Coma Progenitor observed at z>3
Ke Shi, Kyoung-Soo Lee, Arjun Dey +15
We present a detailed census of galaxies in and around PC217.96+32.3, a spectroscopically confirmed Coma analog at z=3.78. Diverse galaxy types identified in the field include Lya…
Discovery of a Very Large (~20 kpc) Galaxy at z=3.72
Kyoung-Soo Lee, Arjun Dey, Thomas Matheson +12
We report the discovery and spectroscopic confirmation of a very large star-forming Lyman Break galaxy, G6025, at z_spec=3.721+/-0.003. In the rest-frame ~2100A, G6025 subtends ~24…
