An extreme ram-pressure stripping event in a protocluster at redshift 4.3
Dazhi Zhou, Scott C. Chapman, Manuel Aravena +16
In the nearby Universe, the environment plays a crucial role in suppressing star formation in dense regions. In particular, ram-pressure stripping (RPS) is a major mechanism for re…
Early Results from GLASS-JWST. XXVI. Spatially Resolved Star Formation and Balmer Decrements at from NIRISS Slitless Spectroscopy
Pengfei Ren, Xin Wang, Yuxuan Pang +10
Using JWST/NIRISS slitless spectroscopy, we present spatially resolved Balmer decrement measurements for 79 galaxies at , which are gravitationally lensed by the for…
The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses
D. Gilman, A. M. Nierenberg, T. Treu +24
The formation of gravitationally bound overdensities of dark matter (DM), or \textit{halos}, is a generic prediction of theories with particle DM. We present a measurement of halo…
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…
GOALS-JWST: Resolved multi-phase molecular gas in IRAS 20551-4250 using JWST and ALMA
D. Kakkad, Y. Song, T. S. -Y. Lai +24
Studying the content and distribution of molecular gas provides key insights into how feedback from Active Galactic Nuclei (AGN) and star formation influences galaxy evolution, sin…
A High Resolution Search for Dual AGN Candidates in Mergers: A Pre-Selection Strategy using Keck AO
Camilo Vazquez, S. Satyapal, G. Canalizo +20
Accreting supermassive black holes (SMBHs) in galaxy mergers with separations 1 kpc are crucial to our understanding of SMBH growth, galaxy evolution, and SMBH binary evolution…
