Extreme Values of Black Hole to Stellar Mass Ratio for High-Redshift Galaxies
Cameron Heather, Teeraparb Chantavat, Siri Chongchitnan +1
With recent data from the \emph{James Webb Space Telescope} (JWST), it is possible to calculate the mass of the supermassive black holes at the center of galaxies, and the stellar…

Cluster number counts in dark energy model with energy and momentum coupling to dark matter
Chattree Wongsangwal, Khamphee Karwan, Stharporn Sapa +1
The influences on the cluster number counts from the coupling between dark energy and dark matter with momentum transfer are investigated. We find that the extrapolated linear dens…

The brightest X-ray AGNs at redshift
Cameron Heather, Teeraparb Chantavat, Siri Chongchitnan +1
Given recent X-ray observations of high-redshift active galactic nuclei (AGNs), we consider whether the extreme luminosities of these AGNs are consistent with current semi-analytic…
