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…
Extreme-value modelling of the brightest galaxies at
Cameron Heather, Teeraparb Chantavat, Siri Chongchitnan +1
Data from the James Webb Space Telescope have revealed an intriguing population of bright galaxies at high redshifts. In this work, we use extreme-value statistics to calculate the…
Morphological evolution of disk galaxies and their concentration, asymmetry and clumpiness (CAS) properties in simulations across Toomre's parameter
Teeraparb Chantavat, Suraphong Yuma, Punnapha Malelohit +1
We investigate the morphological and structural evolutions of disk galaxies in simulations for a wide range of Toomre's parameter. In addition to the inspection of conventional…
Observational Constraints on Extended Starobinsky and Weyl Gravity Model of Inflation
Piyabut Burikham, Teeraparb Chantavat, Pongsapat Boonaom
We present constraints on the extended Starobinsky and Weyl gravity model of inflation using updated available observational data. The data includes cosmic microwave background (CM…
The most massive Population III stars
Teeraparb Chantavat, Siri Chongchitnan, Joseph Silk
Recent data from the James Webb Space Telescope suggest that there are realistic prospects for detecting the earliest generation of stars at redshift ~20. These metal-poor, gaseous…
Extreme Primordial Black Holes
Siri Chongchitnan, Teeraparb Chantavat, Jenna Zunder
We present a formalism for calculating the probability distribution of the most massive primordial black holes (PBHs) expected within an observational volume. We show how current o…
Redshift-space distortion from dynamical dark energy with time-dependent Lagrangian perturbation theory
Chakkrit Kaeonikhom, Teeraparb Chantavat
We apply the Lagrangian perturbation theory with time-dependent growth functions at second and third order of perturbation with the aim to model the effect of dynamical dark energy…
Void profile from Planck lensing potential map
Teeraparb Chantavat, Utane Sawangwit, Benjamin D. Wandelt
We use the lensing potential map from Planck CMB lensing reconstruction analysis and the "Public Cosmic Void Catalog" to measure the stacked void lensing potential. In this profile…
Cosmological parameter constraints from CMB lensing with cosmic voids
Teeraparb Chantavat, Utane Sawangwit, P. M. Sutter +1
We investigate the potential of using cosmic voids as a probe to constrain cosmological parameters through the gravitational lensing effect of the cosmic microwave background (CMB)…
Large Scale Structure Forecast Constraints on Particle Production During Inflation
Teeraparb Chantavat, Christopher Gordon, Joseph Silk
Bursts of particle production during inflation provide a well-motivated mechanism for creating bump like features in the primordial power spectrum. Current data constrains these fe…
Probing the Primordial Power Spectrum with Cluster Number Counts
Teeraparb Chantavat, Christopher Gordon, Joseph Silk
We investigate how well galaxy cluster number counts can constrain the primordial power spectrum. Measurements of the primary anisotropies in the cosmic microwave background (CMB)…
