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…
A detailed study of massive galaxies in a protocluster at z=3.13
Ke Shi, Jun Toshikawa, Zheng Cai +2
We present a detailed study of Near-IR selected galaxies in a protocluster field at z = 3.13. Protocluster galaxies are selected using the available mutliwavelength data with the p…
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…
Constraining dark energy using observational growth rate data
K. Shi, Y. F. Huang, T. Lu
Observational growth rate data had been derived from observations of redshift distortions in galaxy redshift surveys. Here we use the growth rate data to place constraints on the d…
A comprehensive comparison of cosmological models from latest observational data
Ke Shi, Yongfeng Huang, Tan Lu
We investigate in detail some popular cosmological models in light of the latest observational data, including the Union2.1 supernovae compilation, the baryon acoustic oscillation…
