Galaxy populations in protoclusters at cosmic noon
Moira Andrews, M. Celeste Artale, Ankit Kumar +20
We investigate the physical properties and redshift evolution of simulated galaxies residing in protoclusters at cosmic noon, to understand the influence of the environment on gala…
Lyman-Alpha Escape from Low-Mass, Compact, High-Redshift Galaxies
Ragadeepika Pucha, Naveen A. Reddy, Arjun Dey +5
We investigate the effects of stellar populations and sizes on Ly escape in 27 spectroscopically confirmed and 35 photometric Lyman-Alpha Emitters (LAEs) at z 2.65 in…
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…
The Diversity of Diffuse Ly Nebulae around Star-Forming Galaxies at High Redshift
Rui Xue, Kyoung-Soo Lee, Arjun Dey +6
We report the detection of diffuse Ly emission, or Ly halos (LAHs), around star-forming galaxies at and in the NOAO Deep Wide-Field Survey Boötes field.…
Spectroscopic Confirmation of a Protocluster at z=3.786
Arjun Dey, Kyoung-Soo Lee, Naveen Reddy +5
We present new observations of the field containing the z=3.786 protocluster, PC217.96+32.3. We confirm that it is one of the largest and most overdense high-redshift structures kn…
