MAMMOTH-Grism: Gas-phase Metallicity Gradients of Star-forming Galaxies in Protocluster Environments at Cosmic Noon
Yi-Ming Yang, Xin Wang, Chao-Wei Tsai +11
Environment plays a crucial role in shaping galaxy formation, yet the impact of overdensities on the internal chemical structure of galaxies at cosmic noon is still under debate. H…
MAMMOTH-LyC: Investigating the Role of Galaxy Mergers in a Strong Lyman Continuum Leaker at
Shengzhe Wang, Xin Wang, Matthew A. Malkan +16
The MAMMOTH-LyC survey is a cycle 30 Hubble Space Telescope (HST) medium program obtaining 18-orbit-deep WFC3/UVIS F225W imaging in two massive galaxy protocluster fields at $z\sim…
MAMMOTH-Grism: Revisiting the Mass-Metallicity Relation in Protocluster Environments at Cosmic Noon
Yiming Yang, Xin Wang, Xianlong He +12
We present one of the first measurements of the mass-metallicity relation (MZR) in multiple massive protoclusters at cosmic noon, using Hubble Space Telescope (HST) G141 slitless s…
MAMMOTH-MOSFIRE: Environmental Effects on Galaxy Interstellar Medium at
Hang Zhou, Xin Wang, Matthew A. Malkan +16
The MAMMOTH-MOSFIRE program is a deep Keck/MOSFIRE K-band spectroscopic follow-up of emission-line galaxies identified in the MAMMOTH-Grism HST/WFC3 G141 slitless spectroscopic sur…
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…
A first measurement of galaxy merger rate increasing in dynamically colder protoclusters at cosmic noon
Shuang Liu, Xian Zhong Zheng, Valentino Gonzalez +10
The process of galaxy cluster formation likely leaves an imprint on the properties of its individual member galaxies. Understanding this process is essential for uncovering the evo…
