Mergers Drive Structural Complexity but Not Starbursts in Lyman- Emitters at : A JWST Spatially Resolved View
Qi Song, F. S. Liu, Jian Ren +6
Recent observations with the James Webb Space Telescope (JWST) reveal that the merger fraction among Ly emitters (LAEs) at redshifts is significantly higher than previou…
The Size Evolution and the Size-Mass Relation of Lyman-Alpha Emitters across as Observed by JWST
Qi Song, F. S. Liu, Jian Ren +14
Understanding the morphological structures of Lyman-alpha emitters (LAEs) is crucial for unveiling their formation pathways and the physical origins of Ly emission. However, the…
The JWST Unveils the Bimodal Nature of Lyman Alpha Emitters at 3 <z<7: Pristine versus Merger-Driven Populations
Jian Ren, F. S. Liu, Nan Li +8
We present a systematic study of merging galaxies among Lyman-alpha emitters (LAEs) using JWST/NIRCam high-resolution imaging data. From a large sample of 817 spectroscopically con…
Calibrating non-parametric morphological indicators from {\it JWST} images for galaxies over
Jian Ren, F. S. Liu, Nan Li +6
The measurements of morphological indicators of galaxies are often influenced by a series of observational effects. In this study, we utilize a sample of over 800 TNG50 simulated g…
Revisiting Galaxy Evolution in Morphology in the COSMOS field (COSMOS-ReGEM):I. Merging Galaxies
Jian Ren, Nan Li, F. S. Liu +3
We revisit the evolution of galaxy morphology in the COSMOS field over the redshift range , using a large and complete sample of 33,605 galaxies with a stellar ma…
No evidence for feedback: Unexceptional Low-ionization winds in Host galaxies of Low Luminosity Active Galactic Nuclei at Redshift z ~1
Hassen M. Yesuf, David C. Koo, S. M. Faber +6
We study winds in 12 X-ray AGN host galaxies at z ~ 1. We find, using the low-ionization Fe II 2586 absorption in the stacked spectra, that the probability distribution function (P…
Ongoing growth of the brightest cluster galaxies via major dry mergers in the last ~6 Gyr
F. S. Liu, F. J. Lei, X. M. Meng +1
Brightest Cluster Galaxies (BCGs) might have been assembled relatively late (z<1) via mergers. By exploiting the high-resolution HST/ACS imaging, we find four BCGs (COSMOS-P 125516…
From Starburst to Quiescence: Testing AGN feedback in Rapidly Quenching Post-Starburst Galaxies
Hassen M. Yesuf, S. M. Faber, Jonathan R. Trump +5
Post-starbursts are galaxies in transition from the blue cloud to the red sequence. Although they are rare today, integrated over time they may be an important pathway to the red s…
Thermal and non-thermal emission in the Cygnus X region
W. F. Xu, X. Y. Gao, J. L. Han +1
Radio continuum observations detect non-thermal synchrotron and thermal bremsstrahlung radiation. Separation of the two different emission components is crucial to study the proper…
Serendipitous discovery of a massive cD galaxy at z=1.096: Implications for the early formation and late evolution of cD galaxies
F. S. Liu, Yicheng Guo, David C. Koo +18
We have made a serendipitous discovery of a massive cD galaxy at z=1.096 in a candidate rich cluster in the HUDF area of GOODS-South. This brightest cluster galaxy is the most dist…
Star formation activities in early-type brightest cluster galaxies
F. S. Liu, Shude Mao, X. M. Meng
We identify a total of 120 early-type Brightest Cluster Galaxies (BCGs) at 0.1<z<0.4 in two recent large cluster catalogues selected from the Sloan Digital Sky Survey (SDSS). They…
A catalog of 132,684 clusters of galaxies identified from Sloan Digital Sky Survey III
Z. L. Wen, J. L. Han, F. S. Liu
Using the photometric redshifts of galaxies from the Sloan Digital Sky Survey III (SDSS-III), we identify 132,684 clusters in the redshift range of 0.05<z<0.8. Monte Carlo simulati…
Mass Function of Rich Galaxy Clusters and Its Constraint on sigma_8
Z. L. Wen, J. L. Han, F. S. Liu
The mass function of galaxy clusters is a powerful tool to constrain cosmological parameters, e.g., the mass fluctuation on the scale of 8 h^{-1} Mpc, sigma_8, and the abundance of…
