Beyond UV: Rest-frame B-band and Apparent Luminosity Functions of z=5-9 Galaxies
Nicha Leethochawalit, Takahiro Morishita, Tirawut Worrakitpoonpon +1
We present new measurements of galaxy luminosity functions (LFs) from JWST/NIRCam imaging over the redshift range z=4.5-9.7, using photometric catalogs from JADES and public extrag…
Extracting the X-ray reverberation response functions from the AGN light curves using an autoencoder
Sanhanat Deesamutara, Poemwai Chainakun, Tirawut Worrakitpoonpon +5
We study the X-ray reverberation in active galactic nuclei (AGN) using the variational autoencoder (VAE), which is a machine-learning algorithm widely used for signal processing an…
Bar instability and formation timescale across Toomre's parameter and central mass concentration: slow bar formation or true stability
Tirawut Worrakitpoonpon
We investigate the bar formation process using -body simulations across the Toomre's parameter and central mass concentration (CMC), focusing principally on the format…
Violent relaxation in one-dimensional self-gravitating system: deviation from the Vlasov limit due to finite- effect
Tirawut Worrakitpoonpon
We investigate the effect of a finite particle number on the violent relaxation leading to the Quasi-Stationary State (QSS) in a one-dimensional self-gravitating system. From t…
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…
Dynamical analysis of Maclaurin disk with velocity dispersion and its influence on bar formation
T. Worrakitpoonpon
We investigate the influence of Toomre's parameter on the bar-forming dynamics of Maclaurin disk using -body simulations. According to the Toomre's criterion, local velocity…
Formation of spiral structure from the violent relaxation of self-gravitating disks
Tirawut Worrakitpoonpon
We present the numerical study of the formation of spiral structure in the context of violent relaxation. Initial conditions are the out-of-equilibrium disks of self-gravitating pa…
Limitation of symmetry breaking by gravitational collapse: the revisit of Lin-Mestel-Shu instability
Tirawut Worrakitpoonpon
We revisit the topic of shape evolution during the spherical collapse of an -body system. Our main objective is to investigate the critical particle number below which, during a…
Particle number dependence in the non-linear evolution of N-body self-gravitating systems
David Benhaiem, Michael Joyce, Francesco Sylos Labini +1
Simulations of purely self-gravitating N-body systems are often used in astrophysics and cosmology to study the collisionless limit of such systems. Their results for macroscopic q…
Angular momentum generation in cold gravitational collapse
D. Benhaiem, M. Joyce, F. Sylos Labini +1
During the violent relaxation of a self-gravitating system a significant fraction of its mass may be ejected. If the time varying gravitational field also breaks spherical symmetry…
Spherical symmetry breaking in cold gravitational collapse of isolated systems
Tirawut Worrakitpoonpon
We study, using -body simulation, the shape evolution in gravitational collapse of cold uniform spherical system. The central interest is on how the deviation from spherical sym…
Quasi-stationary states in the self-gravitating sheet model
Michael Joyce, Tirawut Worrakitpoonpon
We study quasi-stationary states (QSS) resulting from violent relaxation in the one-dimensional self-gravitating "sheet model", revisiting in particular the question of the adequac…
Relaxation to thermal equilibrium in the self-gravitating sheet model
Michael Joyce, Tirawut Worrakitpoonpon
We revisit the issue of relaxation to thermal equilibrium in the so-called "sheet model", i.e., particles in one dimension interacting by attractive forces independent of their sep…
